Read this manual thoroughly before proceeding with installation, connections (wiring), operation, or maintenance and
inspection. Ensure you have sound knowledge of the device and familiarize yourself with all safety information and
precautions before proceeding to operate the inverter.
Safety precautions are classified into the following two categories in this manual.
Failure to heed the information indicated by this symbol may lead to dangerous conditions,
possibly resulting in death or serious bodily injuries.
Failure to heed the information indicated by this symbol may lead to dangerous conditions,
possibly resulting in minor or light bodily injuries and/or substantial property damage.
Failure to heed the information contained under the CAUTION title can also result in serious consequences. These safety
precautions are of utmost importance and must be observed at all times.
Application
• The JAGUAR VXG is designed to drive a three-phase induction motor. Do not use it for single-phase motors or for
other purposes.
Fire or an accident could occur.
• The JAGUAR VXG may not be used for a life-support system or other purposes directly related to the human safety.
• Though the JAGUAR VXG is manufactured under strict quality control, install safety devices for applications where
serious accidents or property damages are foreseen in relation to the failure of it.
An accident could occur.
Installation
• Install the inverter on a base made of metal or other non-flammable material.
Otherwise, a fire could occur.
• Do not place flammable object nearby.
Doing so could cause fire.
• Inverters with a capacity of 30 kW or above, whose protective structure is IP00, involve a possibility that a human body
may touch the live conductors of the main circuit terminal block. Inverters to which an optional DC reactor is connected
also involve the same. Install such inverters in an inaccessible place.
Otherwise, electric shock or injuries could occur.
• Do not support the inverter by its front cover during transportation.
Doing so could cause a drop of the inverter and injuries.
• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter or from
accumulating on the heat sink.
• When changing the positions of the top and bottom mounting bases, use only the specified screws.
Otherwise, a fire or an accident might result.
• Do not install or operate an inverter that is damaged or lacking parts.
Doing so could cause fire, an accident or injuries.
Wiring
i
• If no zero-phase current (earth leakage current) detective device such as a ground-fault relay is installed in the upstream
power supply line in order to avoid the entire power supply system's shutdown undesirable to factory operation, install
a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) individually to inverters to
break the individual inverter power supply lines only.
Otherwise, a fire could occur.
• When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or
residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent protection)
in the path of each pair of power lines to inverters. Use the recommended devices within the recommended current
capacity.
• Use wires in the specified size.
• Tighten terminals with specified torque.
Otherwise, a fire could occur.
• When there is more than one combination of an inverter and motor, do not use a multicore cable for the purpose of
handling their wirings together.
• Do not connect a surge killer to the inverter's output (secondary) circuit.
Doing so could cause a fire.
• Be sure to connect an optional DC reactor (DCR) when the capacity of the power supply transformer exceeds 500 kVA
and is 10 times or more the inverter rated capacity.
Otherwise, a fire could occur.
• Ground the inverter in compliance with the national or local electric code.
• Be sure to ground the inverter's grounding terminals G.
Otherwise, an electric shock or a fire could occur.
• Qualified electricians should carry out wiring.
• Be sure to perform wiring after turning the power OFF.
Otherwise, an electric shock could occur.
• Be sure to perform wiring after installing the inverter unit.
Otherwise, an electric shock or injuries could occur.
• Ensure that the number of input phases and the rated voltage of the product match the number of phases and the voltage
of the AC power supply to which the product is to be connected.
Otherwise, a fire or an accident could occur.
• Do not connect the power supply wires to output terminals (U, V, and W).
• When connecting a DC braking resistor (DBR), never connect it to terminals other than terminals P(+) and DB.
Doing so could cause fire or an accident.
• In general, sheaths of the control signal wires are not specifically designed to withstand a high voltage (i.e., reinforced
insulation is not applied). Therefore, if a control signal wire comes into direct contact with a live conductor of the main
circuit, the insulation of the sheath might break down, which would expose the signal wire to a high voltage of the main
circuit. Make sure that the control signal wires will not come into contact with live conductors of the main circuit.
Doing so could cause an accident or an electric shock.
• Before changing the switches or touching the control circuit terminal symbol plate, turn OFF the power and wait at
least five minutes for inverters with a capacity of 22 kW or below, or at least ten minutes for inverters with a
capacity of 30 kW or above. Make sure that the LED monitor and charging lamp are turned OFF. Further, make sure,
using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has
dropped to the safe level (+25 VDC or below).
Otherwise, an electric shock could occur.
• The inverter, motor and wiring generate electric noise. Be careful about malfunction of the nearby sensors and devices.
To prevent them from malfunctioning, implement noise control measures.
Otherwise an accident could occur.
• The leakage current of the EMC filter built-in type of inverters is comparatively large. Be sure to perform protective
grounding.
Otherwise, an electric shock could occur.
ii
Operation
• Be sure to mount the front cover before turning the power ON. Do not remove the cover when the inverter power is ON.
Otherwise, an electric shock could occur.
• Do not operate switches with wet hands.
Doing so could cause electric shock.
• If the auto-reset function has been selected, the inverter may automatically restart and drive the motor depending on the
cause of tripping. Design the machinery or equipment so that human safety is ensured at the time of restarting.
Otherwise, an accident could occur.
• If the stall prevention function (current limiter), automatic deceleration (anti-regenerative control), or overload
prevention control has been selected, the inverter may operate with acceleration/deceleration or frequency different
from the commanded ones. Design the machine so that safety is ensured even in such cases.
key on the keypad is effective only when the keypad operation is enabled with function code F02 (= 0, 2 or 3).
• The
When the keypad operation is disabled, prepare an emergency stop switch separately for safe operations.
Switching the run command source from keypad (local) to external equipment (remote) by turning ON the "Enable
key. To enable the
key for an emergency stop, select the STOP
communications link" command LE disables the
key priority with function code H96 (= 1 or 3).
• If any of the protective functions have been activated, first remove the cause. Then, after checking that the all run
commands are set to OFF, release the alarm. If the alarm is released while any run commands are set to ON, the inverter
may supply the power to the motor, running the motor.
Otherwise, an accident could occur.
• If you enable the "Restart mode after momentary power failure" (Function code F14 = 3 to 5), then the inverter
automatically restarts running the motor when the power is recovered.
Design the machinery or equipment so that human safety is ensured after restarting.
• If the user configures the function codes wrongly without completely understanding this Instruction Manual and the
JAGUAR VXG User's Manual, the motor may rotate with a torque or at a speed not permitted for the machine.
An accident or injuries could occur.
• Even if the inverter has interrupted power to the motor, if the voltage is applied to the main circuit input terminals L1/R,
L2/S and L3/T, voltage may be output to inverter output terminals U, V, and W.
• Even if the run command is set to OFF, voltage is output to inverter output terminals U, V, and W if the servo-lock
command is ON.
• Even if the motor is stopped due to DC braking or preliminary excitation, voltage is output to inverter output terminals
U, V, and W.
An electric shock may occur.
• The inverter can easily accept high-speed operation. When changing the speed setting, carefully check the
specifications of motors or equipment beforehand.
Otherwise, injuries could occur.
• Do not touch the heat sink and braking resistor because they become very hot.
Doing so could cause burns.
• The DC brake function of the inverter does not provide any holding mechanism.
Injuries could occur.
• Ensure safety before modifying the function code settings.
Run commands (e.g., "Run forward" FWD), stop commands (e.g., "Coast to a stop" BX), and frequency change
commands can be assigned to digital input terminals. Depending upon the assignment states of those terminals,
modifying the function code setting may cause a sudden motor start or an abrupt change in speed.
• When the inverter is controlled with the digital input signals, switching run or frequency command sources with the
related terminal commands (e.g., SS1, SS2, SS4, SS8, Hz2/Hz1, Hz/PID, IVS, and LE) may cause a sudden motor start
or an abrupt change in speed.
• Ensure safety before modifying customizable logic related function code settings (U codes and related function codes)
or turning ON the "Cancel customizable logic" terminal command CLC. Depending upon the settings, such
modification or cancellation of the customizable logic may change the operation sequence to cause a sudden motor
start or an unexpected motor operation.
An accident or injuries could occur.
iii
Maintenance and inspection, and parts replacement
• Before proceeding to the maintenance/inspection jobs, turn OFF the power and wait at least five minutes for
inverters with a capacity of 22 kW or below, or at least ten minutes for inverters with a capacity of 30 kW or
above. Make sure that the LED monitor and charging lamp are turned OFF. Further, make sure, using a multimeter or a
similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25
VDC or below).
Otherwise, an electric shock could occur.
• Maintenance, inspection, and parts replacement should be made only by qualified persons.
• Take off the watch, rings and other metallic objects before starting work.
• Use insulated tools.
Otherwise, an electric shock or injuries could occur.
• Never modify the inverter.
Doing so could cause an electric shock or injuries.
Disposal
• Treat the inverter as an industrial waste when disposing of it.
Otherwise injuries could occur.

Canada) by installation within precautions listed below.
1. Solid state motor overload protection (motor protection by electronic thermal overload relay) is provided in each model.
Use function codes F10 to F12 to set the protection level.
2. Use Cu wire only.
3. Use Class 1 wire only for control circuits.
4. Short circuit rating
"Suitable For Use On A Circuit Of Delivering Not More Than 100,000 rms Symmetrical Amperes, 240 Volts Maximum
for 200V class input 22 kW or less, 230 Volts maximum for 200V class input 30 kW or above when protected by Class
J Fuses or a Circuit Breaker having an interrupting rating not less than 100,000 rms Symmetrical Amperes, 240 Volts
Maximum." Models FRN; rated for 200V class input.
"Suitable For Use On A Circuit Of Delivering Not More Than 100,000 rms Symmetrical Amperes, 480 Volts Maximum
when protected by Class J Fuses or a Circuit Breaker having an interrupting rating not less than 100,000 rms
Symmetrical Amperes, 480 Volts Maximum." Models VXG; rated for 400V class input.
"Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit protection must be
provided in accordance with the National Electrical Code and any additional local codes."
5. Field wiring connections must be made by a UL Listed and CSA Certified closed-loop terminal connector sized for the
wire gauge involved. Connector must be fixed using the crimp tool specified by the connector manufacturer.
6. All circuits with terminals L1/R, L2/S, L3/T, R0, T0, R1, T1 must have a common disconnect and be connected to the
same pole of the disconnect if the terminals are connected to the power supply.

Chapter 1 BEFORE USING THE INVERTER
1.1 Acceptance Inspection
Unpack the package and check the following:
(1) An inverter and instruction manual (this book) are contained in the package.
• The inverter is not equipped with a keypad when it is shipped. Mount a separately ordered keypad on the
inverter. This manual describes the inverter with a remote keypad. For inverters with a multi-function keypad,
read the Multi-function Keypad Instruction Manual in conjunction with this manual.
• Inverters with a capacity of 55 kW in VT mode and inverters with 75 kW or above require a DC reactor
(DCR) to be connected. Be sure to connect a separately ordered DCR to those inverters.
(2) The inverter has not been damaged during transportation—there should be no dents or parts missing.
(3) The inverter is the type you ordered. You can check the type and specifications on the main nameplate. (Main and sub
nameplates are attached to the inverter and are located as shown on the next page.) For inverters with a capacity of 30 kW
or above, the mass is printed on the main nameplate.

1.3 Precautions for Using Inverters
1.3.1 Precautions in introducing inverters
This section provides precautions in introducing inverters, e.g. precautions for installation environment, power supply lines,
wiring, and connection to peripheral equipment. Be sure to observe those precautions.
„ Installation environment
Install the inverter in an environment that satisfies the requirements listed in Table 2.1 in Chapter 2.
IMO strongly recommends installing inverters in a panel for safety reasons, in particular, when installing the ones whose
enclosure rating is IP00.
When installing the inverter in a place out of the specified environmental requirements, it is necessary to derate the inverter
or consider the panel engineering design suitable for the special environment or the panel installation location. For details,
refer to the IMO technical information "Engineering Design of Panels" or consult your IMO representative.
The special environments listed below require using the specially designed panel or considering the panel installation
location.
Environments
Possible problems
Highly concentrated
sulfidizing gas or
other corrosive gases
Corrosive gases cause parts
inside the inverter to corrode,
resulting in an inverter
malfunction.
Any of the following measures may
be necessary.
A lot of conductive
dust or foreign
material (e.g., metal
powders or shavings,
carbon fibers, or
carbon dust)
Entry of conductive dust into
the inverter causes a short
circuit.
Any of the following measures may
be necessary.
A lot of fibrous or
paper dust
Fibrous or paper dust
accumulated on the heat sink
lowers the cooing effect.
Any of the following measures may
be necessary.
Entry of dust into the inverter
causes the electronic circuitry
to malfunction.
Sample measures
- Mount the inverter in a sealed
panel with IP6X or air-purge
mechanism.
- Place the panel in a room free
from influence of the gases.
- Mount the inverter in a sealed
panel.
- Place the panel in a room free
from influence of the conductive
dust.
Applications
Paper manufacturing,
sewage disposal, sludge
treatment, tire
manufacturing, gypsum
manufacturing, metal
processing, and a
particular process in
textile factories.
Wiredrawing machines,
metal processing,
extruding machines,
printing presses,
combustors, and industrial
waste treatment.
Textile manufacturing and
paper manufacturing.
- Mount the inverter in a sealed
panel that shuts out dust.
- Ensure a maintenance space for
periodical cleaning of the heat sink
in panel engineering design.
- Employ external cooling when
mounting the inverter in a panel
for easy maintenance and perform
periodical maintenance.
High humidity or
dew condensation
In an environment where a
humidifier is used or where
the air conditioner is not
equipped with a
dehumidifier, high humidity
or dew condensation results,
which causes a
short-circuiting or
malfunction of electronic
circuitry inside the inverter.
- Put a heating module such as a
space heater in the panel.
Outdoor installation.
Vibration or shock
exceeding the
specified level
If a large vibration or shock
exceeding the specified level
is applied to the inverter, for
example, due to a carrier
running on seam joints of
rails or blasting at a
construction site, the inverter
structure gets damaged.
- Insert shock-absorbing materials
between the mounting base of the
inverter and the panel for safe
mounting.
Installation of an inverter
panel on a carrier or
self-propelled machine.
Halogen compounds such as
methyl bromide used in
fumigation corrodes some
parts inside the inverter.
- When exporting an inverter built
in a panel or equipment, pack
them in a previously fumigated
wooden crate.
- When packing an inverter alone
for export, use a laminated veneer
lumber (LVL).
Exporting.
Fumigation for
export packaging
Film manufacturing line,
pumps and food
processing.
Ventilating fan at a
construction site or a press
machine.
„ Storage environment
The storage environment in which the inverter is stored after purchase is different from the operation environment. For details,
refer to the VXG-MANUAL

For an inverter with an output circuit filter installed, the total secondary wiring length should be 400 m or less (100 m or
less under the vector control).
If further longer secondary wiring is required, consult your IMO representative.
(5) Precautions for surge voltage in driving a motor by an inverter (especially for 400 V class, general-purpose motors)
If the motor is driven by a PWM-type inverter, surge voltage generated by switching the inverter component may be
superimposed on the output voltage and may be applied to the motor terminals. Particularly if the wiring length is long,
the surge voltage may deteriorate the insulation resistance of the motor. Implement any of the following measures.
- Use a motor with insulation that withstands the surge voltage.
- Connect a surge suppressor unit at the motor terminal.
- Connect an output circuit filter to the output terminals (secondary circuits) of the inverter.
- Minimize the wiring length between the inverter and motor (10 to 20 m or less).
(6) When an output circuit filter is inserted in the secondary circuit or the wiring between the inverter and the motor is long,
a voltage loss occurs due to reactance of the filter or wiring so that the insufficient voltage may cause output current
oscillation or a lack of motor output torque. To avoid it, select the constant torque load by setting the function code F37
(Load Selection/Auto Torque Boost/Auto Energy Saving Operation 1) to "1" and keep the inverter output voltage at a
higher level by configuring H50/H52 (Non-linear V/f Pattern, Frequency) and H51/H53 (Non-linear V/f Pattern,
Voltage).
„ Precautions for connection of peripheral equipment
(1) Phase-advancing capacitors for power factor correction
Do not mount a phase-advancing capacitor for power factor correction in the inverter's input (primary) or output
(secondary) circuit. Mounting it in the input (primary) circuit takes no effect. To correct the inverter power factor, use an
optional DC reactor (DCR). Mounting it in the output (secondary) circuit causes an overcurrent trip, disabling operation.
An overvoltage trip that occurs when the inverter is stopped or running with a light load is assumed to be due to surge
current generated by open/close of phase-advancing capacitors in the power system. An optional DC/AC reactor
(DCR/ACR) is recommended as a measure to be taken at the inverter side.
Input current to an inverter contains a harmonic component that may affect other motors and phase-advancing capacitors
on the same power supply line. If the harmonic component causes any problems, connect an optional DCR/ACR to the
inverter. In some cases, it is necessary to insert a reactor in series with the phase-advancing capacitors.
(2) Power supply lines (Application of a DC/AC reactor)
Use an optional DC reactor (DCR) when the capacity of the power supply transformer is 500 kVA or more and is 10
times or more the inverter rated capacity or when there are thyristor-driven loads. If no DCR is used, the
percentage-reactance of the power supply decreases, and harmonic components and their peak levels increase. These
factors may break rectifiers or capacitors in the converter section of the inverter, or decrease the capacitance of the
capacitors.
If the input voltage unbalance rate is 2% to 3%, use an optional AC reactor (ACR).

™ ,(& - 7KUHH SKDVH DYHUDJH YROWDJH 9
(3) DC reactor (DCR) for correcting the inverter input power factor (for suppressing harmonics)
To correct the inverter input power factor (to suppress harmonics), use an optional DCR. Using a DCR increases the
reactance of inverter’s power source so as to decrease harmonic components on the power source lines and correct the
power factor of the inverter.
1-4
BEFORE USING THE INVERTER
(1) Route the wiring of the control circuit terminals as far from the wiring of the main circuit as possible. Otherwise electric
noise may cause malfunctions.
(2) Fix the control circuit wires inside the inverter to keep them away from the live parts of the main circuit (such as the
terminal block of the main circuit).
(3) If more than one motor is to be connected to a single inverter, the wiring length should be the sum of the length of the
wires to the motors.
(4) Precautions for high frequency leakage currents
If the wiring distance between an inverter and a motor is long, high frequency currents flowing through stray capacitance
across wires of phases may cause an inverter overheat, overcurrent trip, increase of leakage current, or it may not assure
the accuracy in measuring leakage current. Depending on the operating condition, an excessive leakage current may
damage the inverter.
To avoid the above problems when directly connecting an inverter to a motor, keep the wiring distance 50 m or less for
inverters with a capacity of 3.7 kW or below, and 100 m or less for inverters with a higher capacity.
If the wiring distance longer than the specified above is required, lower the carrier frequency or insert an output circuit
filter as shown below.
When the inverter drives two or more motors connected in parallel (group drive), in particular, using shielded wires, the
stray capacitance to the earth is large, so lower the carrier frequency or insert an output circuit filter.

Exclusively designed for nominal applied motor of 37 kW
or above.
Select a DCR matching not the inverter but the nominal applied motor. Applicable reactors differ depending
upon the selected CT, MT, or VT mode even on the same type of inverters.
(4) PWM converter for correcting the inverter input power factor
Using a PWM converter (High power-factor, regenerative PWM converter, RHC series) corrects the inverter power factor
up to nearly 100%. When combining an inverter with a PWM converter, disable the main power loss detection by setting
the function code H72 to "0." If the main power loss detection is enabled (H72 = 1 by factory default), the inverter
interprets the main power as being shut down, ignoring an entry of a run command.
(5) Molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker
(ELCB)
Install a recommended MCCB or RCD/ELCB (with overcurrent protection) in the primary circuit of the inverter to
protect the wiring. Since using an MCCB or RCD/ELCB with a lager capacity than recommended ones breaks the
protective coordination of the power supply system, be sure to select recommended ones. Also select ones with
short-circuit breaking capacity suitable for the power source impedance.

Otherwise, a fire could occur.
(6) Magnetic contactor (MC) in the inverter input (primary) circuit
Avoid frequent ON/OFF operation of the magnetic contactor (MC) in the input circuit; otherwise, the inverter failure may
/
keys on the
result. If frequent start/stop of the motor is required, use FWD/REV terminal signals or the
inverter's keypad.
The frequency of the MC's ON/OFF should not be more than once per 30 minutes. To assure 10-year or longer service
life of the inverter, it should not be more than once per hour.
• From the system's safety point of view, it is recommended to employ such a sequence that shuts down the
magnetic contactor (MC) in the inverter input circuit with an alarm output signal ALM issued on inverter's
programmable output terminals. The sequence minimizes the secondary damage even if the inverter breaks.
When the sequence is employed, connecting the MC's primary power line to the inverter's auxiliary control
power input makes it possible to monitor the inverter's alarm status on the keypad.
• The breakdown of a braking unit or misconnection of an external braking resistor may trigger that of the
inverter's internal parts (e.g., charging resistor). To avoid such a breakdown linkage, introduce an MC and
configure a sequence that shuts down the MC if a DC link voltage establishment signal is not issued within
three seconds after the MC is switched on.
For the braking transistor built-in type of inverters, assign a transistor error output signal DBAL on inverter's
programmable output terminals to switch off the MC in the input circuit.
(7) Magnetic contactor (MC) in the inverter output (secondary) circuit
If a magnetic contactor (MC) is inserted in the inverter's output (secondary) circuit for switching the motor to a
commercial power or for any other purposes, it should be switched on and off when both the inverter and motor are
completely stopped. This prevents the contact point from getting rough due to a switching arc of the MC. The MC should
not be equipped with any main circuit surge killer.
Applying a commercial power to the inverter's output circuit breaks the inverter. To avoid it, interlock the MC on the
motor's commercial power line with the one in the inverter output circuit so that they are not switched ON at the same
time.
(8) Surge absorber/surge killer
Do not install any surge absorber or surge killer in the inverter's output (secondary) lines.
„ Noise reduction
If noise generated from the inverter affects other devices, or that generated from peripheral equipment causes the inverter to
malfunction, follow the basic measures outlined below.
(1) If noise generated from the inverter affects the other devices through power wires or grounding wires:
- Isolate the grounding terminals of the inverter from those of the other devices.
- Connect a noise filter to the inverter power wires.
- Isolate the power system of the other devices from that of the inverter with an insulated transformer.
- Decrease the inverter's carrier frequency (F26).
(2) If induction or radio noise generated from the inverter affects other devices:
- Isolate the main circuit wires from the control circuit wires and other device wires.
- Put the main circuit wires through a metal conduit pipe, and connect the pipe to the ground near the inverter.
- Install the inverter into the metal panel and connect the whole panel to the ground.
- Connect a noise filter to the inverter's power wires.
- Decrease the inverter's carrier frequency (F26).
(3) When implementing measures against noise generated from peripheral equipment:
- For inverter's control signal wires, use twisted or shielded-twisted wires. When using shielded-twisted wires, connect
the shield of the shielded wires to the common terminals of the control circuit.
- Connect a surge absorber in parallel with magnetic contactor's coils or other solenoids (if any).
1-6
BEFORE USING THE INVERTER
If no zero-phase current (earth leakage current) detective device such as a ground-fault relay is installed in the
upstream power supply line in order to avoid the entire power supply system's shutdown undesirable to factory
operation, install a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)
individually to inverters to break the individual inverter power supply lines only.
Chap. 1
„ Leakage current
A high frequency current component generated by insulated gate bipolar transistors (IGBTs) switching on/off inside the
inverter becomes leakage current through stray capacitance of inverter input and output wires or a motor. If any of the
problems listed below occurs, take an appropriate measure against them.
Problem
An earth leakage circuit
breaker* that is connected
to the input (primary) side
has tripped.
*With overcurrent protection
An external thermal relay
was activated.
Measures
1)
2)
3)
4)
Decrease the carrier frequency.
Make the wires between the inverter and motor shorter.
Use an earth leakage circuit breaker with lower sensitivity than the one currently used.
Use an earth leakage circuit breaker that features measures against the high frequency
current component.
1) Decrease the carrier frequency.
2) Increase the current setting of the thermal relay.
3) Use the electronic thermal overload protection built in the inverter, instead of the
external thermal relay.
„ Selecting inverter capacity
(1) To drive a general-purpose motor, select an inverter according to the nominal applied motor rating listed in the standard
specifications table. When high starting torque is required or quick acceleration or deceleration is required, select an
inverter with one rank higher capacity than the standard.
(2) Special motors may have larger rated current than general-purpose ones. In such a case, select an inverter that meets the
following condition.
Inverter rated current > Motor rated current
1.3.2 Precautions in running inverters
Precautions for running inverters to drive motors or motor-driven machinery are described below.
„ Motor temperature
When an inverter is used to run a general-purpose motor, the motor temperature becomes higher than when it is operated with
a commercial power supply. In the low-speed range, the motor cooling effect will be weakened, so decrease the output torque
of the motor when running the inverter in the low-speed range.
„ Motor noise
When a general-purpose motor is driven by an inverter, the noise level is higher than that when it is driven by a commercial
power supply. To reduce noise, raise carrier frequency of the inverter. Operation at 60 Hz or higher can also result in higher
noise level.
„ Machine vibration
When an inverter-driven motor is mounted to a machine, resonance may be caused by the natural frequencies of the
motor-driven machinery. Driving a 2-pole motor at 60 Hz or higher may cause abnormal vibration. If it happens, do any of
the following:
- Consider the use of a rubber coupling or vibration-proof rubber.
- Use the inverter's jump frequency control feature to skip the resonance frequency zone(s).
- Use the vibration suppression related function codes that may be effective. For details, refer to the description of H80 in
Chapter 5 "FUNCTION CODES."
1-7
Chap. 1
1.3.3 Precautions in using special motors
When using special motors, note the followings.
„ Explosion-proof motors
„ Submersible motors and pumps
These motors have a larger rated current than general-purpose motors. Select an inverter whose rated output current is greater
than that of the motor. These motors differ from general-purpose motors in thermal characteristics. Decrease the thermal time
constant of the electronic thermal overload protection to match the motor rating.
„ Brake motors
For motors equipped with parallel-connected brakes, their power supply for braking must be supplied from the inverter input
(primary) circuit. If the power supply for braking is mistakenly connected to the inverter's output (secondary) circuit, the
brake may not work when the inverter output is shut down. Do not use inverters for driving motors equipped with
series-connected brakes.
„ Geared motors
If the power transmission mechanism uses an oil-lubricated gearbox or speed changer/reducer, then continuous operation at
low speed may cause poor lubrication. Avoid such operation.
„ Synchronous motors
It is necessary to take special measures suitable for this motor type. Contact your IMO representative for details.
„ Single-phase motors
Single-phase motors are not suitable for inverter-driven variable speed operation.
„ High-speed motors
If the reference frequency is set to 120 Hz or higher to drive a high-speed motor, test-run the combination of the inverter and
motor beforehand to check it for the safe operation.
1-8
BEFORE USING THE INVERTER
When driving an explosion-proof motor with an inverter, use a combination of a motor and an inverter that has been
approved in advance.

(Note 1) When inverters are mounted
side-by-side without any clearance between
them (22 kW or below), the surrounding
temperature should be within the range from
-10 to +40qC.
(Note 2) Do not install the inverter in an
environment where it may be exposed to lint,
cotton waste or moist dust or dirt which will
clog the heat sink of the inverter. If the
inverter is to be used in such an environment,
install it in a dustproof panel of your system.
(Note 3) If you use the inverter in an altitude
above 1000 m, you should apply an output
current derating factor as listed in Table 2.2.
2.2 Installing the Inverter
(1) Mounting base
Install the inverter on a base made of metal or other non-flammable material. Do not
mount the inverter upside down or horizontally.
Install the inverter on a base made of metal or other non-flammable material.
Otherwise, a fire could occur.
(2) Clearances
Ensure that the minimum clearances indicated in Figure 2.1 and Table 2.3 are maintained
at all times. When mounting the inverter in the panel of your system, take extra care with
ventilation inside the panel as the surrounding temperature easily rises. Do not install the
inverter in a small panel with poor ventilation.
„ When mounting two or more inverters
When mounting two or more inverters in the same unit or panel, basically lay them out
side by side. When mounting them necessarily one above the other, be sure to separate
them with a partition plate or the like so that any heat radiating from an inverter will not
affect the one/s above.
As long as the surrounding temperature is 40°C or lower, inverters with a capacity of 22
kW or below can be mounted side by side without any clearance between them.

MOUNTING AND WIRING THE INVERTER
Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials
from getting into the inverter or from accumulating on the heat sink.
Otherwise, a fire or accident could occur.
Chap. 2
„ When employing external cooling
In external cooling, the heat sink, which dissipates about 70% of the total heat (total
loss) generated into air, is situated outside the equipment or the panel. The external
cooling, therefore, significantly reduces heat radiating inside the equipment or panel.
To employ external cooling for inverters with a capacity of 22 kW or below, use the
external cooling attachment option; for those with a capacity of 30 kW or above,
simply change the positions of the mounting bases.
To utilize external cooling for inverters with a capacity of 30 kW or above, change the positions of the top and bottom
mounting bases from the edge to the center of the inverter as shown in Figure 2.3.
Screws differ in size and count for each inverter. Refer to the table below.

1) Remove all of the base fixing screws and the case fixing screws from the top of the inverter.
2) Move the top mounting base to the center of the inverter and secure it to the case fixing screw holes with the base fixing
screws. (After changing the position of the top mounting base, some screws may be left unused.)
3) Remove the base fixing screws from the bottom of the inverter, move the bottom mounting base to the center of the
inverter, and secure it with the base fixing screws, just as in step 2). (Inverters with a capacity of 220 kW or below have
no case fixing screws on the bottom.)

2.3.3 Wiring precautions
Follow the rules below when performing wiring for the inverter.
(1) Make sure that the source voltage is within the rated voltage range specified on the nameplate.
(2) Be sure to connect the three-phase power wires to the main circuit power input terminals L1/R, L2/S and L3/T of the
inverter. If the power wires are connected to other terminals, the inverter will be damaged when the power is turned ON.
(3) Always connect the grounding terminal to prevent electric shock, fire or other disasters and to reduce electric noise.
(4) Use crimp terminals covered with insulated sleeves for the main circuit terminal wiring to ensure a reliable connection.
(5) Keep the power supply wiring (primary circuit) and motor wiring (secondary circuit) of the main circuit, and control
circuit wiring as far away as possible from each other.
(6) After removing a screw from the main circuit terminal block, be sure to restore the screw even if no wire is connected.
(7) Use the wiring guide to separate wiring. For inverters with a capacity of 3.7 kW or below, the wiring guide separates the
main circuit wires and the control circuit wires. For inverters with a capacity of 5.5 to 22 kW, it separates the upper and
lower main circuit wires, and control circuit wires. Be careful about the wiring order.
VXG9A-4E
VXG30A5-4E
„ Preparing for the wiring guide
Inverters with a capacity of 11 to 22 kW (three-phase 200 V class series) are sometimes lacking in wiring space for main
circuit wires depending upon the wire materials used. To assure a sufficient wiring space, remove the clip-off sections
(see below) as required with a nipper. Note that the enclosure rating of IP20 may not be ensured when the wiring guide
itself is removed to secure a space for thick main circuit wiring.
Before removal of clip-off sections
After removal of clip-off sections

.
2-8
MOUNTING AND WIRING THE INVERTER
Recommended wire size: 0.65 to 0.82 mm2 (AWG 19 or 18)*
(8) In some types of inverters, the wires from the main circuit terminal block cannot be straight routed. Route such wires as
shown below so that the front cover is set into place.
(9) For inverters with a capacity of 500 kW or 630 kW, two L2/S input terminals are arranged vertically to the terminal
block. When connecting wires to these terminals, use the bolts, washers and nuts that come with the inverter, as shown
below.
• When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or
residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent protection)
in the path of each pair of power lines to inverters. Use the recommended devices within the recommended current
capacity.
• Be sure to use wires in the specified size.
• Tighten terminals with specified torque.
Otherwise, a fire could occur.
• When there is more than one combination of an inverter and motor, do not use a multicore cable for the purpose of
handling their wirings together.
• Do not connect a surge killer to the inverter's output (secondary) circuit.
Doing so could cause a fire.
• Ground the inverter in compliance with the national or local electric code.
• Be sure to ground the inverter's grounding terminals G.
Otherwise, an electric shock or fire could occur.
• Qualified electricians should carry out wiring.
• Be sure to perform wiring after turning the power OFF.
Otherwise, electric shock could occur.
• Be sure to perform wiring after installing the inverter unit.
Otherwise, electric shock or injuries could occur.
• Ensure that the number of input phases and the rated voltage of the product match the number of phases and the
voltage of the AC power supply to which the product is to be connected.
Otherwise, a fire or an accident could occur.
• Do not connect the power source wires to inverter output terminals (U, V, and W).
Doing so could cause fire or an accident.

Install a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit
breaker (ELCB) (with overcurrent protection function) in the primary circuit of the inverter to protect wiring. Ensure that the circuit
breaker capacity is equivalent to or lower than the recommended capacity.
The R0 and T0 terminals are provided for inverters with a capacity of 1.5 kW or above.
To retain an alarm output signal ALM issued on inverter's programmable output terminals by the protective function or to keep the
keypad alive even if the main power has shut down, connect these terminals to the power supply lines. Without power supply to these
terminals, the inverter can run.
*4
Normally no need to be connected. Use these terminals when the inverter is equipped with a high power-factor, regenerative PWM
converter (RHC series).
*5
When connecting an optional DC reactor (DCR), remove the jumper bar from the terminals P1 and P(+).
Inverters with a capacity of 55 kW in LD mode and inverters with 75 kW or above require a DCR to be connected. Be sure to connect it
to those inverters.
Use a DCR when the capacity of the power supply transformer exceeds 500 kVA and is 10 times or more the inverter rated capacity, or
when there are thyristor-driven loads in the same power supply line.
*6
Inverters with a capacity of 7.5 kW or below have a built-in braking resistor (DBR) between the terminals P(+) and DB.
*7
A grounding terminal for a motor. Use this terminal if needed.
*8
For control signal wires, use twisted or shielded-twisted wires. When using shielded-twisted wires, connect the shield of them to the
common terminals of the control circuit. To prevent malfunction due to noise, keep the control circuit wiring away from the main circuit
wiring as far as possible (recommended: 10 cm or more). Never install them in the same wire duct. When crossing the control circuit
wiring with the main circuit wiring, set them at right angles.
*9
The connection diagram shows factory default functions assigned to digital input terminals [X1] to [X7], [FWD] and [REV], transistor
output terminals [Y1] to [Y4], and relay contact output terminals [Y5A/C] and [30A/B/C].
When connecting an external braking resistor (DBR), be sure to disconnect the built-in one.
*10 Switching connectors in the main circuits. For details, refer to "
Switching connectors" later in this section.
*11 Slide switches on the control printed circuit board (control PCB). Use these switches to customize the inverter operations. For details,
refer to Section 2.3.6 "Setting up the slide switches."
*12 When using the Enable input function, be sure to remove the jumper wire from terminals [EN] and [PLC]. For opening and closing the
hardware circuit between terminals [EN] and [PLC], use safety components such as safety relays and safety switches that comply with
EN954-1, Category 3 or higher. Be sure to use shielded wires exclusive to terminals [EN] and [PLC]. (Do not put them together with
any other control signal wire in the same shielded core.) Ground the shielding layer. For details, refer to Chapter 9, Section 9.6
"Compliance with EN954-1, Category 3."
When not using the Enable input function, keep the terminals between [EN] and [PLC] short-circuited with the jumper wire (factory
default).

Chap. 2
*2 Install a magnetic contactor (MC) for each inverter to separate the inverter from the power supply, apart from the MCCB or RCD/ELCB,
when necessary.
Connect a surge absorber in parallel when installing a coil such as the MC or solenoid near the inverter.
Primary grounding terminal ( G) for inverter enclosure
Two grounding terminals ( G) are not exclusive to the power supply wiring (primary circuit) or motor wiring (secondary
circuit). Be sure to ground either of the two grounding terminals for safety and noise reduction. The inverter is designed for
use with safety grounding to avoid electric shock, fire and other disasters.
The grounding terminal for inverter enclosure should be grounded as follows:
1) Ground the inverter in compliance with the national or local electric code.
2) Use a thick grounding wire with a large surface area and keep the wiring length as short as possible.
An EMC filter built-in type of inverters with a capacity of 5.5 to 11 kW (both 200 V and 400 V class series) has
three grounding terminals. For effective noise suppression, connect grounding wires to the specified grounding
terminals. (Refer to Chapter 9, Section 9.3.2 "Recommended installation procedure.")
Inverter output terminals U, V, and W and secondary grounding terminals ( G) for motor
Inverter’s output terminals should be connected as follows:
1) Connect the three wires of the 3-phase motor to terminals U, V, and W, aligning the phases each other.
2) Connect the secondary grounding wire to the grounding terminal ( G).
When there is more than one combination of an inverter and motor, do not use a multicore cable for the purpose of
handling their wirings together.
DC reactor terminals P1 and P(+)
Connect a DC reactor (DCR) to these terminals for power factor correction.
1) Remove the jumper bar from terminals P1 and P(+).
2) Connect an optional DCR to those terminals.
• The wiring length should be 10 m or below.
• Do not remove the jumper bar when a DCR is not used.
• Inverters with a capacity of 55 kW in LD mode and inverters with 75 kW or above require a DCR to be
connected. Be sure to connect it to those inverters.
• If a PWM converter is connected to the inverter, no DCR is required.
Be sure to connect an optional DC reactor (DCR) when the capacity of the power supply transformer exceeds 500 kVA
and is 10 times or more the inverter rated capacity.
Otherwise, a fire could occur.

In inverters with a capacity of 7.5 kW or below, if the capacity of the built-in DC braking resistor (DBR) is insufficient since
the inverter undergoes frequent start/stop or heavy inertial load, mount an optional external DC braking resistor (DBR) with a
larger capacity to increase the braking capability, using the following steps. Before mounting the external DBR, remove the
built-in DBR.
1) For inverters with a capacity of 0.4 to 3.7 kW, disconnect the wiring of the built-in DBR from terminals P(+) and DB; for
inverters with a capacity of 5.5 and 7.5 kW, disconnect the wiring from terminal DB and the internal relay terminal (see
the figure below).
Insulate the terminals of the disconnected wires with insulating tape or other materials.

2) Connect an optional DBR to terminals P(+) and DB.
The internal relay terminal on inverters with a capacity of 5.5 and 7.5 kW is left unused.
3) Arrange the DBR and inverter so that the wiring length comes to 5 m or less and twist the two DBR wires or route them
together in parallel.

A DC link bus of other inverter(s) or a PWM converter is connectable to these terminals.
When you need to use the DC link bus terminals P(+) and N(-), consult your Fuji Electric representative.
Switching connectors
„ Power switching connectors (CN UX) (for 400 V class series with 75 kW or above)
The 400 V class series with 75 kW or above is equipped with a set of switching connectors (male) which should be
configured according to the power source voltage and frequency. By factory default, a jumper (female connector) is set to U1.
If the power supply to the main power inputs (L1/R, L2/S, L3/T) or the auxiliary fan power input terminals (R1, T1) matches
the conditions listed below, change the jumper to U2.

„ Fan power supply switching connectors (CN R and CN W) (for 200 V class series with 37 kW or above and
400 V class series with 75 kW or above)
The standard JAGUAR VXG series accepts DC-linked power input in combination with a PWM converter. The 200 V class
series with 37 kW or above and 400 V class series with 75 kW or above, however, contain AC-driven components such as AC
fans. To supply AC power to those components, exchange the CN R and CN W connectors as shown below and connect the
AC power line to the auxiliary fan power input terminals (R1, T1).
For the switching instructions, see Figures 2.6 and 2.7.

Inserting/Removing the Jumpers
Main circuit power input terminals L1/R, L2/S, and L3/T (three-phase input)
The three-phase input power lines are connected to these terminals.
1) For safety, make sure that the molded case circuit breaker (MCCB) or magnetic contactor (MC) is turned OFF before
wiring the main circuit power input terminals.
2) Connect the main circuit power supply wires (L1/R, L2/S and L3/T) to the input terminals of the inverter via an MCCB
or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)*, and an MC if necessary.
It is not necessary to align phases of the power supply wires and the input terminals of the inverter with each other.
* With overcurrent protection
It is recommended to insert a manually operable magnetic contactor (MC) that allows you to disconnect the inverter
from the power supply in an emergency (e.g., when the protective function is activated), preventing a failure or
accident from causing secondary disasters.
To drive the inverter with single-phase input power, consult your IMO representative.
Auxiliary control power input terminals R0 and T0 (for inverters with a capacity of 1.5 kW or above)
In general, the inverter runs normally without power supplied to the auxiliary control power input terminals R0 and T0. If the
inverter main power is shut down, however, no power is supplied to the control circuit so that the inverter cannot issue a
variety of output signals or display on the keypad.
To retain an alarm output signal ALM issued on inverter's programmable output terminals by the protective function or to
keep the keypad alive even if the main power has shut down, connect the auxiliary control power input terminals R0 and T0
to the power supply lines. If a magnetic contactor (MC) is installed in the inverter's primary circuit, connect the primary
circuit of the MC to these terminals R0 and T0.
Terminal rating:
200 to 240 VAC, 50/60 Hz, Maximum current 1.0 A (200 V class series with 22 kW or below)
200 to 230 VAC, 50/60 Hz, Maximum current 1.0 A (200 V class series with 30 kW or above)
380 to 480 VAC, 50/60 Hz, Maximum current 0.5 A (400 V class series)
When introducing a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB),
connect its output (secondary) side to terminals R0 and T0. Connecting its input (primary) side to those terminals
causes the RCD/ELCB to malfunction since the input power voltage to the inverter is three-phase but the one to
terminals R0 and T0 is single-phase. To avoid such problems, be sure to insert an insulation transformer or auxiliary
B contacts of a magnetic contactor in the location shown in Figure 2.8.

Earth Leakage Circuit Breaker (ELCB)

To remove each of the jumpers, pinch its upper side between
your fingers, unlock its fastener, and pull it up.
When mounting it, fit the jumper over the connector until it
snaps into place.
When connecting a PWM converter with an inverter, do not connect the power supply line directly to terminals R0
and T0. If a PWM is to be connected, insert an insulation transformer or auxiliary B contacts of a magnetic contactor
at the power supply side.
For connection examples at the PWM converter side, refer to the PWM Converter Instruction Manual.
Figure 2.9
Connection Example of PWM Converter
Auxiliary fan power input terminals R1 and T1
The 200 V class series with 37 kW or above and 400 V class series with 75 kW or above are equipped with terminals R1 and
T1. Only if the inverter works with the DC-linked power input whose source is a PWM converter, these terminals are used to
feed AC power to the fans, while they are not used in any power system of ordinary configuration.
In this case, set up the fan power supply switching connectors (CN R and CN W).
Terminal rating:
200 to 220 VAC/50 Hz, 200 to 230 VAC/60 Hz, Maximum current 1.0 A (200 V class series with 37 kW or above)
380 to 440 VAC/50 Hz, 380 to 480 VAC/60 Hz, Maximum current 1.0 A (400 V class series with 75 kW to 400 kW)
380 to 440 VAC/50 Hz, 380 to 480 VAC/60 Hz, Maximum current 2.0 A (400 V class series with 500 kW and 630 kW)
2.3.5 Wiring for control circuit terminals
In general, the covers of the control signal wires are not specifically designed to withstand a high voltage (i.e., reinforced
insulation is not applied). Therefore, if a control signal wire comes into direct contact with a live conductor of the main
circuit, the insulation of the cover might break down, which would expose the signal wire to a high voltage of the main
circuit. Make sure that the control signal wires will not come into contact with live conductors of the main circuit.
Failure to observe these precautions could cause electric shock or an accident.
Noise may be emitted from the inverter, motor and wires.
Take appropriate measures to prevent the nearby sensors and devices from malfunctioning due to such noise.
An accident could occur.
„ Connecting/disconnecting wires to/from a control circuit terminal
Strip the wire end by 8 to 10 mm as shown below.
Strip length of wire end
8 to 10 mm
Type of screwdriver (tip shape)
Flat (0.6 u 3.5 mm)
For strand wires, the strip length specified above should apply after twisting of them.
If the strip length is out of the specified range, the wire may not be firmly clamped or may be short-circuited with
other wires.
Twist the end of the stripped wires for easy insertion and insert it firmly into the wire inlet on the control circuit terminal.
If the insertion is difficult, hold down the clamp release button on the terminal with a flat screwdriver.
When disconnecting the wires from the terminal, hold down the clamp release button on the terminal with a flat
screwdriver and pull out the wires.

- Since low level analog signals are handled, these signals are especially susceptible to the external noise
effects. Route the wiring as short as possible (within 20 m) and use shielded wires. In principle, ground
the shielded sheath of wires; if effects of external inductive noises are considerable, connection to
terminal [11] may be effective. As shown in Figure 2.11, be sure to ground the single end of the shield
to enhance the shield effect.
- Use a twin-contact relay for low level signals if the relay is used in the control circuit. Do not connect
the relay's contact to terminal [11].
- When the inverter is connected to an external device outputting the analog signal, the external device
may malfunction due to electric noise generated by the inverter. If this happens, according to the
circumstances, connect a ferrite core (a toroidal core or equivalent) to the device outputting the analog
signal or connect a capacitor having the good cut-off characteristics for high frequency between control
signal wires as shown in Figure 2.12.
- Do not apply a voltage of +7.5 VDC or higher to terminal [C1]. Doing so could damage the internal
control circuit.

„ Using a relay contact to turn [X1] to [X7], [FWD], or [REV] ON or OFF
Figure 2.14 shows two examples of a circuit that uses a relay contact to turn control signal input [X1] to
[X7], [FWD], or [REV] ON or OFF. In circuit (a), the slide switch SW1 has been turned to SINK, whereas
in circuit (b) it has been turned to SOURCE.
Note: To configure this kind of circuit, use a high quality relay.

Figure 2.15 shows two examples of a circuit that uses a programmable logic controller (PLC) to turn
control signal input [X1] to [X7], [FWD], or [REV] ON or OFF. In circuit (a), the slide switch SW1 has
been turned to SINK, whereas in circuit (b) it has been turned to SOURCE.
In circuit (a) below, short-circuiting or opening the transistor's open collector circuit in the PLC using an
external power supply turns ON or OFF control signal [X1] to [X7], [FWD], or [REV]. When using this
type of circuit, observe the following:
- Connect the + node of the external power supply (which should be isolated from the PLC's power) to
terminal [PLC] of the inverter.
- Do not connect terminal [CM] of the inverter to the common terminal of the PLC.

MOUNTING AND WIRING THE INVERTER
(1) Safety stop function that is compliant with EN954-1, Category 3. This terminal
allows the hardware circuit to stop the inserter's output transistor and coast the motor
to a stop.
(2) This terminal is exclusively used for the source mode input. When it is
short-circuited with terminal [PLC], the Enable input is ON (ready for inverter run);
when it is opened, the inverter coasts the motor to a stop. (This terminal is not
interlocked with the slide switch SW1.)
(3) By factory default, terminals [EN] and [PLC] are short-circuited with each other
using a jumper wire, disabling this function. To enable it, be sure to remove the
jumper wire.

„ For inputting a pulse train through the digital input terminal [X7]
• Inputting from a pulse generator with an open collector transistor output
Stray capacity on the wiring between the pulse generator and the inverter may disable transmission of the
pulse train. As a countermeasure against this problem, insert a pull-up resistor between the open collector
output signal (terminal [X7]) and the power source terminal (terminal [PLC]) if the switch selects the
SINK mode input; insert a pull-down resistor between the output signal and the digital common terminal
(terminal [CM]) if the switch selects the SOURCE mode input.
A recommended pull-up/down resistor is 1k: 2 W. Check if the pulse train is correctly transmitted
because stray capacity is significantly affected by the wire types and wiring conditions.

- When a transistor output drives a control relay, connect a surge-absorbing diode
across relay’s coil terminals.
- When any equipment or device connected to the transistor output needs to be
supplied with DC power, feed the power (+24 VDC: allowable range: +22 to
+27 VDC, 100 mA max.) through the [PLC] terminal. Short-circuit between the
terminals [CMY] and [CM] in this case.

Wiring Route and Fixing Position for the Control Circuit Wires
- Route the wiring of the control circuit terminals as far from the wiring of the main circuit as possible.
Otherwise electric noise may cause malfunctions.
- Fix the control circuit wires with a cable tie inside the inverter to keep them away from the live parts of the
main circuit (such as the terminal block of the main circuit).
2.3.6 Setting up the slide switches
Before changing the switches or touching the control circuit terminal symbol plate, turn OFF the power and wait at
least five minutes for inverters with a capacity of 22 kW or below, or at least ten minutes for inverters with a
capacity of 30 kW or above. Make sure that the LED monitor and charging lamp are turned OFF. Further, make sure,
using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped
to the safe level (+25 VDC or below).
An electric shock may result if this warning is not heeded as there may be some residual electric charge in the DC
bus capacitor even after the power has been turned OFF.
Switching the slide switches located on the control PCB allows you to customize the operation mode of the analog output
terminals, digital I/O terminals, and communications ports. The locations of those switches are shown in Figure 2.20.
To access the slide switches, remove the front cover so that you can see the control PCB. For inverters with a capacity of 30
kW or above, open also the keypad enclosure.
For details on how to remove the front cover and how to open and close the keypad enclosure, refer to Section 2.3.1
"Removing and mounting the front cover and the wiring guide."

3.3.2 Monitoring light alarms
The JAGUAR VXG identifies abnormal states in two categories--Heavy alarm and Light alarm. If the former occurs, the
inverter immediately trips; if the latter occurs, the inverter shows the ODO on the LED monitor and blinks the KEYPAD
CONTROL LED but it continues to run without tripping.

H82 beforehand.
Assigning the LALM signal to any one of the digital output terminals with any of function codes E20 to E24 and E27 (= 98)
enables the inverter to output the LALM signal on that terminal upon occurrence of a light alarm.
For details of the light alarm objects, refer to Chapter 6 "TROUBLESHOOTING," Table 6.1.

It is also possible to check the factors of the last three light alarms B (last) to B (3rd last).
For details of the menu transition of the maintenance information, refer to Section 3.4.6 "Reading maintenance information."
„ How to remove the current light alarm
After checking the current light alarm factor, to switch the LED monitor back to the running status display (e.g., output
frequency) from the ODO indication, press the
key in Running mode.
If the light alarm factor has been removed, the KEYPAD CONTROL LED stops blinking and the LALM signal turns OFF. If
not (e.g. DC fan lock), the KEYPAD CONTROL LED continues blinking and the LALM signal remains ON.

• Displaying I/O signal status in hexadecimal
Each I/O terminal is assigned to bit 15 through bit 0 as shown in Table 3.13. An unassigned bit is interpreted as "0." Allocated
bit data is displayed on the LED monitor as four hexadecimal digits ( to I each).
On the JAGUAR VXG, digital input terminals [FWD] and [REV] are assigned to bits 0 and 1, respectively. Terminals [X1]
through [X7] are assigned to bits 2 through 10. The bit is set to "1" when the corresponding input terminal is short-circuited
(ON), and it is set to "0" when the terminal is open (OFF). For example, when [FWD] and [X1] are ON (short-circuited) and all
the others are OFF (open), is displayed on LED4 to LED1.
Digital output terminals [Y1] through [Y4] are assigned to bits 0 through 3. Each bit is set to "1" when the output terminal [Y1],
[Y2], [Y3] or [Y4] is short-circuited with [CMY] (ON), and "0" when it is open (OFF).
The status of the relay contact output terminal [Y5A/C] is assigned to bit 4. It is set to "1" when the circuit between output
terminals [Y5A] and [Y5C] is closed. The status of the relay contact output terminals [30A/B/C] is assigned to bit 8. It is set to
"1" when the circuit between output terminals [30A] and [30C] is closed, and "0" when the circuit between [30A] and [30C] is
open.
For example, if [Y1] is ON, [Y2] through [Y4] are OFF, the circuit between [Y5A] and [Y5C] is open, and the circuit between
[30A] and [30C] is closed, then " " is displayed on the LED4 through LED1.

Function code E42 (LED display filter) allows you to filter the monitoring signals for the monitor items such as output
frequency and output current. Increase the E42 data if the monitored values are unstable and unreadable due to
fluctuation of load.
3.3.2 Monitoring light alarms
The JAGUAR VXG identifies abnormal states in two categories--Heavy alarm and Light alarm. If the former occurs, the
inverter immediately trips; if the latter occurs, the inverter shows the ODO on the LED monitor and blinks the KEYPAD
CONTROL LED but it continues to run without tripping.
Which abnormal states are categorized as a light alarm ("Light alarm" object) should be defined with function codes H81 and
H82 beforehand.
Assigning the LALM signal to any one of the digital output terminals with any of function codes E20 to E24 and E27 (= 98)
enables the inverter to output the LALM signal on that terminal upon occurrence of a light alarm.
For details of the light alarm objects, refer to Chapter 6 "TROUBLESHOOTING," Table 6.1.
„ How to check a light alarm factor
When a light alarm occurs, ODO appears on the LED monitor. To check the current light alarm factor, enter Programming mode
key and select B on Menu #5 "Maintenance Information."
by pressing the
It is also possible to check the factors of the last three light alarms B (last) to B (3rd last).
For details of the menu transition of the maintenance information, refer to Section 3.4.6 "Reading maintenance information."
„ How to remove the current light alarm
After checking the current light alarm factor, to switch the LED monitor back to the running status display (e.g., output
frequency) from the ODO indication, press the
key in Running mode.
If the light alarm factor has been removed, the KEYPAD CONTROL LED stops blinking and the LALM signal turns OFF. If
not (e.g. DC fan lock), the KEYPAD CONTROL LED continues blinking and the LALM signal remains ON.

3.4 Programming Mode
The Programming mode provides you with these functions--setting and checking function code data, monitoring maintenance
information and checking input/output (I/O) signal status. The functions can be easily selected with the menu-driven system.
Table 3.4 lists menus available in Programming mode. The leftmost digit (numerals) of each letter string on the LED monitor
indicates the corresponding menu number and the remaining three digits indicate the menu contents.
When the inverter enters Programming mode from the second time on, the menu selected last in Programming mode will be

• Displaying I/O signal status in hexadecimal
Each I/O terminal is assigned to bit 15 through bit 0 as shown in Table 3.13. An unassigned bit is interpreted as "0." Allocated
bit data is displayed on the LED monitor as four hexadecimal digits ( to I each).
On the JAGUAR VXG, digital input terminals [FWD] and [REV] are assigned to bits 0 and 1, respectively. Terminals [X1]
through [X7] are assigned to bits 2 through 10. The bit is set to "1" when the corresponding input terminal is short-circuited
(ON), and it is set to "0" when the terminal is open (OFF). For example, when [FWD] and [X1] are ON (short-circuited) and all
the others are OFF (open), is displayed on LED4 to LED1.
Digital output terminals [Y1] through [Y4] are assigned to bits 0 through 3. Each bit is set to "1" when the output terminal [Y1],
[Y2], [Y3] or [Y4] is short-circuited with [CMY] (ON), and "0" when it is open (OFF).
The status of the relay contact output terminal [Y5A/C] is assigned to bit 4. It is set to "1" when the circuit between output
terminals [Y5A] and [Y5C] is closed. The status of the relay contact output terminals [30A/B/C] is assigned to bit 8. It is set to
"1" when the circuit between output terminals [30A] and [30C] is closed, and "0" when the circuit between [30A] and [30C] is
open.
For example, if [Y1] is ON, [Y2] through [Y4] are OFF, the circuit between [Y5A] and [Y5C] is open, and the circuit between
[30A] and [30C] is closed, then " " is displayed on the LED4 through LED1.

As shown in Table 3.12 and the figure below, each of segments "a" to "dp" on LED1 and LED2 lights when the corresponding
digital input terminal circuit ([FWD], [REV], [X1] to [X7]) is closed; it goes OFF when it is open. Each of segments "a" to "e"
on LED3 lights when the circuit between output terminal [Y1], [Y2], [Y3] or [Y4] and terminal [CMY] or between terminals
[Y5A] and [Y5C] is closed, respectively; it goes OFF when the circuit is open. Segment "a" on LED4 is for terminals
[30A/B/C] and lights when the circuit between terminals [30C] and [30A] is short-circuited (ON) and goes OFF when it is
open.
„ Displaying control I/O signal terminals under communications control
Under communications control, input commands (function code S06) sent via RS-485 or other optional communications can be
displayed in two ways: "with ON/OFF of each LED segment" and "in hexadecimal." The content to be displayed is basically the
same as that for the control I/O signal terminal status display; however, (XF), (XR), and (RST) are added as inputs. Note that
under communications control, the I/O display is in normal logic (using the original signals not inverted)
For details about input commands sent through the communications link, refer to the RS-485 Communication User's
Manual and the instruction manual of communication-related options as well.
„ Displaying control I/O signal terminals on options
The LED monitor can also show the signal status of the terminals on the optional digital input and output interface cards, just
like the signal status of the control circuit terminals.

3.4.8 Copying data -- Menu #7 "Data Copying" --
Menu #7 "Data Copying" is used to read function code data out of an inverter for storing it in the keypad or writing it into
another inverter. It is also used to verify the function code data stored in the keypad with the one configured in the inverter. The
keypad serves as a temporary storage media.
In addition, using Menu #7 allows you to store the running status information in the keypad, detach the keypad from the inverter,
connect it to a PC running JAGUAR Loader at an office or off-site place, and check the inverter running status without
removing the inverter itself.
To store the inverter running status information into the keypad, use "Read data" (UHDG ) or "Read inverter running information"
(FKHF ) function. For details on how to connect the keypad to a PC and check the inverter running status information stored in
the keypad, refer to the JAGUAR Loader Instruction Manual.
Figure 3.6 shows the menu transition in Menu #7 "Data Copying." The keypad can hold function code data for a single inverter.

4.1.2 Checking prior to powering on
Check the following before powering on the inverter.
(1) Check that the wiring is correct.
Especially check the wiring to the inverter input terminals L1/R, L2/S and L3/T and output terminals U, V, and W. Also
check that the grounding wires are connected to the grounding terminals ( G) correctly. See Figure 4.2.
• Never connect power supply wires to the inverter output terminals U, V, and W. Doing so and turning the power ON breaks
the inverter.
• Be sure to connect the grounding wires of the inverter and the motor to the ground electrodes.
Otherwise, an electric shock could occur.
(2) Check the control circuit terminals and main circuit terminals for short circuits or ground faults.

(3) Check for loose terminals, connectors and screws.
(4) Check that the motor is separated from mechanical equipment.
(5) Make sure that all switches of devices connected to the inverter
are turned OFF. Powering on the inverter with any of those
switches being ON may cause an unexpected motor operation.
(6) Check that safety measures are taken against runaway of the
equipment, e.g., a defense to prevent people from access to the
equipment.

The MT-/VT-mode inverter brings out the continuous rated current level which enables the inverter to drive a motor with one or
two ranks higher capacity, but its overload capability (%) against the continuous current level decreases. For the rated current
level, see Chapter 8 "SPECIFICATIONS."
Some versions of the optional multi-function keypad (OP-KP-LCD) do not display the content of the function code F80
when the data is "2," so "2: ---" appears instead of "2: Medium T." However, the function code data can be configured
normally.

„ V/f control with slip compensation inactive
Under this control, the inverter controls a motor with the voltage and frequency according to the V/f pattern specified by
function codes. This control disables all automatically controlled features such as the slip compensation, so no unpredictable
output fluctuation results, enabling stable operation with constant output frequency.
„ V/f control with slip compensation active
Applying any load to an induction motor causes a rotational slip due to the motor characteristics, decreasing the motor rotation.
The inverter’s slip compensation function first presumes the slip value of the motor based on the motor torque generated and
raises the output frequency to compensate for the decrease in motor rotation. This prevents the motor from decreasing the
rotation due to the slip.
That is, this function is effective for improving the motor speed control accuracy.
The compensation value is specified by combination of function codes P12* (Rated slip frequency), P09* (Slip compensation
gain for driving) and P11* (Slip compensation gain for braking).

„ Dynamic torque vector control
To get the maximal torque out of a motor, this control calculates the motor torque for the load applied and uses it to optimize the
voltage and current vector output.
Selecting this control automatically enables the auto torque boost and slip compensation function.
This control is effective for improving the system response to external disturbances such as load fluctuations, and the motor
speed control accuracy.
Note that the inverter may not respond to a rapid load fluctuation since this control is an open-loop V/f control that does not
perform the current control, unlike the vector control. The advantages of this control include larger maximum torque per output
current than that the vector control.
„ V/f control with speed sensor
Applying any load to an induction motor causes a rotational slip due to the motor characteristics, decreasing the motor rotation.
Under V/f control with speed sensor, the inverter detects the motor rotation using the encoder mounted on the motor shaft and
compensates for the decrease in slip frequency by the PI control to match the motor rotation with the commanded speed. This
improves the motor speed control accuracy.
„ Dynamic torque vector control with speed sensor
The difference from the "V/f control with speed sensor" stated above is to calculate the motor torque for the load applied and
use it to optimize the voltage and current vector output for getting the maximal torque out of a motor.
This control is effective for improving the system response to external disturbances such as load fluctuations, and the motor
speed control accuracy.
„ Vector control without speed sensor
This control estimates the motor speed based on the inverter's output voltage and current to use the estimated speed for speed
control. In addition, it decomposes the motor drive current into the exciting and torque current components, and controls each
of those components in vector. No PG (pulse generator) interface card is required. It is possible to obtain the desired response
by adjusting the control constants (PI constants) using the speed regulator (PI controller).
Since this control controls the motor current, it is necessary to secure some voltage margin between the voltage that the inverter
can output and the induced voltage of the motor, by keeping the former lower than the latter.
Although the voltage of the general-purpose motor has usually been adjusted to match the commercial power, keeping the
motor terminal voltage low is necessary in order to secure the voltage margin. If the motor is driven under this control with the
motor terminal voltage being kept low, however, the rated torque cannot be obtained even when the rated current originally
specified for the motor is applied. To secure the rated torque, therefore, it is necessary to use a motor with higher rated current.
(This also applies to the vector control with speed sensor.)
This control is not available for MT-mode inverters, so do not set F42 data to "5" for those inverters.
„ Vector control with speed sensor
This control requires an optional PG (pulse generator) and an optional PG interface card to be mounted on a motor shaft and an
inverter, respectively. The inverter detects the motor's rotational position and speed from PG feedback signals and uses them for
speed control. In addition, it decomposes the motor drive current into the exciting and torque current components, and controls
each of components in vector.
The desired response can be obtained by adjusting the control constants (PI constants) and using the speed regulator (PI
controller). This control enables the speed control with higher accuracy and quicker response than the vector control without
speed sensor.
Since slip compensation, dynamic torque vector control, and vector control with/without speed sensor use motor
parameters, the following conditions should be satisfied; otherwise, full control performance may not be obtained.
• A single motor should be controlled per inverter.
• Motor parameters P02*, P03*, P06* to P23*, P55* and P56* should be properly configured or auto-tuning (P04*)
should be performed.
• The capacity of the motor to be controlled should be two or more ranks lower than that of the inverter under the
dynamic torque vector control; it should be the same as that of the inverter under the vector control with/without
speed sensor. Otherwise, the inverter may not control the motor due to decrease of the current detection resolution.
• The wiring distance between the inverter and motor should be 50 m or less. If it is longer, the inverter may not
control the motor due to leakage current flowing through stray capacitance to the ground or between wires.
Especially, small capacity inverters whose rated current is also small may be unable to control the motor correctly
even when the wiring is less than 50 m. In that case, make the wiring length as short as possible or use a wire with
small stray capacitance (e.g., loosely-bundled cable) to minimize the stray capacitance.

speed, slip compensation, torque vector control, droop control, or overload stop.
In any of the following cases, the full control performance may not be obtained from the inverter because the motor
parameters differ from the factory defaults, so perform auto-tuning. (Refer to Section 4.1.7.)
• The motor to be driven is not a IMO product or is a non-standard product.
• The wiring distance between the inverter and the motor is too long (generally 20 m or more).
• A reactor is inserted between the inverter and the motor.
4.1.7 Function code basic settings and tuning < 2 >
Under the V/f control (F42* = 0 or 2) or dynamic torque vector control (F42* = 1), any of the following cases requires
configuring the basic function codes given below and auto-tuning. (Refer to Figure 4.1 on page 4-1.)
- Driving a non-standard motor
- Driving a general-purpose motor, provided that the wiring distance between the inverter and motor is long or a reactor is

„ Tuning procedure
(1) Selection of tuning type
Check the situation of the machinery and select "Tuning with the motor stopped (P04* = 1)" or "Tuning with the motor running
(P04* = 2)." For the latter tuning, adjust the acceleration and deceleration times (F07 and F08) and specify the rotation direction
that matches the actual rotation direction of the machinery.

(2) Preparation of machinery
Perform appropriate preparations on the motor and its load, such as disengaging the coupling from the motor and deactivating
the safety devices.
(3) Tuning
Set function code P04* to "1" or "2" and press the
key. (The blinking of or on the LED monitor will slow down.)
Enter a run command. The factory default is "
key on the keypad for forward rotation." To switch to reverse rotation
or to select the terminal signal FWD or REV as a run command, change the data of function code F02.
The moment a run command is entered, the display of or lights up, and tuning starts with the motor stopped.
(Maximum tuning time: Approx. 40 to 80 s.)
If P04* = 2, after the tuning in above, the motor is accelerated to approximately 50% of the base frequency and then
tuning starts. Upon completion of measurements, the motor decelerates to a stop.
(Estimated tuning time: Acceleration time + 20 to 75 s + Deceleration time)
If P04* = 2, after the motor decelerates to a stop in above, tuning continues with the motor stopped.
(Maximum tuning time: Approx. 40 to 80 s.)
If the terminal signal FWD or REV is selected as a run command (F02 = 1), HQG appears upon completion of the
measurements. Turning the run command OFF completes the tuning.
If the run command has been given through the keypad or the communications link, it automatically turns OFF upon
completion of the measurements, which completes the tuning.
Upon completion of the tuning, the subsequent function code P06* appears on the keypad.
„ Tuning errors
Improper tuning would negatively affect the operation performance and, in the worst case, could even cause hunting or
deteriorate precision. Therefore, if the inverter finds any abnormality in the tuning results or any error in the tuning process, it
displays HU and discards the tuning data.
Listed below are possible causes that trigger tuning errors.
Possible tuning error causes
Details
Error in tuning results
- An interphase voltage unbalance or output phase loss has been detected.
- Tuning has resulted in an abnormally high or low value of a parameter due to the output
circuit opened.
Output current error
An abnormally high current has flown during tuning.
Sequence error
During tuning, a run command has been turned OFF, or STOP (Force to stop), BX (Coast to
a stop), DWP (Protect from dew condensation), or other similar terminal command has been
received.
Error due to limitation
- During tuning, any of the operation limiters has been activated.
- The maximum frequency or the frequency limiter (high) has limited tuning operation.
Other errors
An undervoltage or any other alarm has occurred.
If any of these errors occurs, remove the error cause and perform tuning again, or consult your IMO representative.

If a filter other than the IMO optional output filter is connected to the inverter's output (secondary) circuit, the tuning
result cannot be assured. When replacing the inverter connected with such a filter, make a note of the old inverter’s
settings for the primary resistance %R1, leakage reactance %X, no-load current, and rated slip frequency, and specify
those values to the new inverter’s function codes.
Vibration that may occur when the motor's coupling is elastic can be regarded as normal vibration due to the output
voltage pattern applied in tuning. The tuning does not always result in an error; however, run the motor and check its
running state.
4.1.8 Function code basic settings and tuning < 3 >
Driving a motor under vector control without speed sensor (F42* = 5) requires auto-tuning, regardless of the motor type. (Refer

Tuning operation
The default value of the speed regulator is set low to prevent your system from oscillation (hunting). However,
hunting may occur during tuning due to machinery-related conditions, causing a tuning error (HU ) or a speed
mismatch error (HUH ). If a tuning error (HU ) occurs, reduce the gain for the speed regulator; if a speed mismatch error
(HUH ) occurs, cancel the speed mismatch detection function (d23=0). After that, perform tuning again.
„ If tuning while the motor is rotating cannot be selected
If the "tuning while the motor is rotating under vector control (P04*=3)" cannot be selected due to restrictions on the machinery,
perform the "tuning with the motor stops (P04*=1)" by following the procedure below. Compared to the former tuning, the
latter may show rather inferior performance in the speed control accuracy or stability, perform sufficient tests beforehand by
connecting the motor with the machinery.
(1) For motors whose motor ratings are unknown such as ones made by other manufacturers
Specify the F04*, F05*, P02*, and P03* data according to the motor rated values printed on the motor 's nameplate.
Specify motor parameters (the data of P06*, P16* to P23*) by obtaining the appropriate values on the datasheet issued
from the motor manufacturer.
For details of conversion from data on the datasheet into ones to be entered as function code data, contact your IMO
representative.
Perform the "tuning with the motor stops (P04*=1)."
(2) Tuning (Tune while the motor stops)
Set function code P04* to "1" and press the
key. (The blinking of on the LED monitor will slow down.)
Enter a run command. The factory default is "
key on the keypad for forward rotation." To select the terminal signal
FWD or REV as a run command, change the data of function code F02.
The moment a run command is entered, the display of lights up, and tuning starts with the motor stopped.
(Maximum tuning time: Approx. 40 s.)
If the terminal signal FWD or REV is selected as a run command (F02 = 1), HQG appears upon completion of the
measurements. Turning the run command OFF completes the tuning.
If the run command has been given through the keypad or the communications link, it automatically turns OFF upon

Check the situation of the machinery and select "Tuning with the motor stopped (P04* = 1)" or "Tuning with the motor running
(P04* = 2)." For the latter tuning, adjust the acceleration and deceleration times (F07 and F08) and specify the rotation direction
that matches the actual rotation direction of the machinery.

The tuning results of motor parameters will be automatically saved into their respective function codes. If P04* tuning is
performed, for instance, the tuning results will be saved into P* codes (Motor 1* parameters).
(2) Preparation of machinery
Perform appropriate preparations on the motor and its load, such as disengaging the coupling from the motor and deactivating
the safety devices.

(3) Tuning
Set function code P04* to "1" or "2" and press the
key. (The blinking of or on the LED monitor will slow down.)
Enter a run command. The factory default is "
key on the keypad for forward rotation." To switch to reverse rotation
or to select the terminal signal FWD or REV as a run command, change the data of function code F02.
The moment a run command is entered, the display of or lights up, and tuning starts with the motor stopped.
(Maximum tuning time: Approx. 40 to 80 s.)
If P04* = 2, after the tuning in above, the motor is accelerated to approximately 50% of the base frequency and then
tuning starts. Upon completion of measurements, the motor decelerates to a stop.
(Estimated tuning time: Acceleration time + 20 to 75 s + Deceleration time)
If P04* = 2, after the motor decelerates to a stop in above, tuning continues with the motor stopped.
(Maximum tuning time: Approx. 40 to 80 s.)
If the terminal signal FWD or REV is selected as a run command (F02 = 1), HQG appears upon completion of the
measurements. Turning the run command OFF completes the tuning.
If the run command has been given through the keypad or the communications link, it automatically turns OFF upon
completion of the measurements, which completes the tuning.
Upon completion of the tuning, the subsequent function code P06* appears on the keypad.
„ Tuning errors
Improper tuning would negatively affect the operation performance and, in the worst case, could even cause hunting or
deteriorate precision. Therefore, if the inverter finds any abnormality in the tuning results or any error in the tuning process, it
displays HU and discards the tuning data.
Listed below are possible causes that trigger tuning errors.
Possible tuning error causes
Details
Error in tuning results
- An interphase voltage unbalance or output phase loss has been detected.
- Tuning has resulted in an abnormally high or low value of a parameter due to the output
circuit opened.
Output current error
An abnormally high current has flown during tuning.
Sequence error
During tuning, a run command has been turned OFF, or STOP (Force to stop), BX (Coast to
a stop), DWP (Protect from dew condensation), or other similar terminal command has been
received.
Error due to limitation
- During tuning, any of the operation limiters has been activated.
- The maximum frequency or the frequency limiter (high) has limited tuning operation.
Other errors
An undervoltage or any other alarm has occurred.
If any of these errors occurs, remove the error cause and perform tuning again, or consult your IMO representative.
If a filter other than the IMO optional output filter is connected to the inverter's output (secondary) circuit, the tuning
result cannot be assured. When replacing the inverter connected with such a filter, make a note of the old inverter’s
settings for the primary resistance %R1, leakage reactance %X, no-load current, and rated slip frequency, and specify
those values to the new inverter’s function codes.
Vibration that may occur when the motor's coupling is elastic can be regarded as normal vibration due to the output
voltage pattern applied in tuning. The tuning does not always result in an error; however, run the motor and check its
running state.
4.1.12 Running the inverter for motor operation check
If the user configures the function codes wrongly without completely understanding this Instruction Manual and the
JAGUAR VXG User's Manual, the motor may rotate with a torque or at a speed not permitted for the machine.
Accident or injury may result.
After completion of preparations for a test run as described above, start running the inverter for motor operation check using the
following procedure.
If any abnormality is found in the inverter or motor, immediately stop operation and investigate the cause referring to
Chapter 6, "TROUBLESHOOTING."

RUNNING THE MOTOR
Depending on the settings of function codes, the motor speed may rise to an unexpectedly high and dangerous
level, particularly, under vector control with/without speed sensor. To avoid such an event, the speed limiting
function is provided.
If the user is unfamiliar with the function code settings (e.g., when the user starts up the inverter for the first time),
it is recommended that the frequency limiter (high) (F15) and the torque control (speed limit 1/2) (d32/d33) be
used. At the startup of the inverter, to ensure safer operation, specify small values to those function codes at first
and gradually increase them while checking the actual operation.
The speed limiting function serves as an overspeed level barrier, or as a speed limiter under torque control. For
details of the speed limiting function, refer to the JAGUAR VXG User's Manual.
-------------------------------------------------------------------------------------------------------------------------------------------------------
4.1.13 Preparation for practical operation
After verifying normal motor running with the inverter in a test run, connect the motor with the machinery and perform wiring
for practical operation.
(1) Configure the application related function codes that operate the machinery.
(2) Check interfacing with the peripheral circuits.
1) Mock alarm
keys" on the keypad for 5 seconds or more and check the alarm
Generate a mock alarm by pressing the " +
sequence. The inverter should stop and issue an alarm output signal (for any fault).
2) Judgment on the life of the DC link bus capacitor
When the multi-function keypad is used, it is necessary to set up the judgment reference level to be applied for the
judgment on the life of the DC link bus capacitor.
When the remote keypad is used, the same setting-up is also necessary in order to judge the life of the DC link bus
capacitor under the practical operating conditions.
For details, refer to Chapter 7 "MAINTENANCE AND INSPECTION."
3) I/O checking
Check interfacing with peripherals using Menu #4 "I/O Checking" on the keypad in Programming mode. For details,
refer to Chapter 3 "OPERATION USING THE KEYPAD."
4) Analog input adjustment
Adjust the analog inputs on terminals [12], [C1] and [V2] using the function codes related to the offset, filter and gain
that minimize analog input errors. For details, refer to Chapter 5 "FUNCTION CODES."
5) Calibrating the [FM] output
Calibrate the full scale of the analog meter connected to the terminals [FM1] and [FM2], using the reference voltage
equivalent to +10 VDC. To output the reference voltage, it is necessary to select the analog output test with the function
code (F31/F35 = 14).
6) Clearing the alarm history
Clear the alarm history saved during the system setup with the function code (H97 = 1).
Depending upon the situation of the practical operation, it may become necessary to modify the settings of the torque
boost (F09*), acceleration/deceleration times (F07/F08), and the PI controller for speed control under the vector
control. Confirm the function code data and modify them properly.
4.2 Special Operations

4.2.2 Remote and local modes
The inverter is available in either remote or local mode. In the remote mode that applies to ordinary operation, the inverter is
driven under the control of the data settings stored in the inverter, whereas in the local mode that applies to maintenance
operation, it is separated from the control system and is driven manually under the control of the keypad.
• Remote mode: Run and frequency commands are selected by function codes or source switching signals except "Select
local (keypad) operation" LOC.
• Local mode: The command source is the keypad, regardless of the settings specified by function codes. The keypad takes
precedence over the settings specified by communications link operation signals.

No specification of the motor rotational direction is required.
The remote and local modes can be switched by a digital input signal provided from the outside of the inverter.
To enable the switching, you need to assign LOC as a digital input signal to any of terminals [X1] to [X7] by setting "35" to any
of E01 to E07, E98 and E99.
Switching from remote to local mode automatically inherits the frequency settings used in remote mode. If the motor is running
at the time of the switching from remote to local, the run command will be automatically turned ON so that all the necessary
data settings will be carried over. If, however, there is a discrepancy between the settings used in remote mode and ones made
on the keypad (e.g., switching from the reverse rotation in remote mode to the forward rotation only in local mode), the inverter
automatically stops.
The transition paths between remote and local modes depend on the current mode and the value (ON/OFF) of LOC, as shown in
the status transition diagram given below. Also, refer to above table for details.
Transition between Remote and Local Modes by LOC
4.2.3 External run/frequency command
By factory default, run and frequency commands are sourced from the keypad. This section provides other external command
source samples--an external frequency command potentiometer (variable resistor) as a frequency command source and external
run switches as run forward/reverse command sources.
Set up those external sources using the following procedure.
(1) Configure the function codes as listed below.

If terminal [FWD] and [REV] are ON, the F02 data cannot be changed. First turn those terminals OFF and then
change the F02 data.
(2) Wire the external frequency command potentiometer to terminals across [13], [12], and [11].
(3) Connect the run forward switch between terminals [FWD] and [CM] and the run reverse switch between [REV] and [CM].
(4) To start running the inverter, rotate the potentiometer to give a voltage to terminal [12] and then turn the run forward or
reverse switch ON (short-circuit).
For precautions in wiring, refer to Chapter 2 "MOUNTING AND WIRING THE INVERTER."

Chapter 5 FUNCTION CODES
5.1 Function Code Tables
Function codes enable the JAGUAR VXG series of inverters to be set up to match your system requirements.
Each function code consists of a 3-letter alphanumeric string. The first letter is an alphabet that identifies its group and the
following two letters are numerals that identify each individual code in the group. The function codes are classified into 13
groups: Fundamental Functions (F codes), Extension Terminal Functions (E codes), Control Functions (C codes), Motor 1
Parameters (P codes), High Performance Functions (H codes), Motor 2, 3 and 4 Parameters (A, b and r codes), Application
Functions 1, 2, and 3 (J, d, and U codes), Link Functions (y codes) and Option Functions (o codes). To determine the
property of each function code, set data to the function code.
This manual does not contain the descriptions of Option Function (o codes). For Option Function (o codes), refer to the
instruction manual for each option.
The following descriptions supplement those given in the function code tables on the following pages.
„ Changing, validating, and saving function code data when the inverter is running

„ Copying data
The keypad is capable of copying of the function code data stored in the inverter's memory into the keypad's memory (refer
to Menu #7 "Data copying" in Programming mode). With this feature, you can easily transfer the data saved in a source
inverter to other destination inverters.
If the specifications of the source and destination inverters differ, some code data may not be copied to ensure safe operation
of your power system. Whether data will be copied or not is detailed with the following symbols in the "Data copying"
column of the function code tables given on the following pages.
Y:
Will be copied unconditionally.
Y1: Will not be copied if the rated capacity differs from the source inverter.
Y2: Will not be copied if the rated input voltage differs from the source inverter.
N:
Will not be copied. (The function code marked with "N" is not subject to the Verify operation, either.)
For details of copying operation, refer to Chapter 3, Section 3.4.8.
„ Using negative logic for programmable I/O terminals
The negative logic signaling system can be used for the programmable, digital input and output terminals by setting the
function code data specifying the properties for those terminals. Negative logic refers to the inverted ON/OFF (logical value
1 (true)/0 (false)) state of input or output signal. An active-ON signal (the function takes effect if the terminal is
short-circuited.) in the normal logic system is functionally equivalent to active-OFF signal (the function takes effect if the
terminal is opened.) in the negative logic system. Active-ON signals can be switched to active-OFF signals, and vice versa,
with the function code data setting, except some signals.
To set the negative logic system for an input or output terminal, enter data of 1000s (by adding 1000 to the data for the
normal logic) in the corresponding function code.

FUNCTION CODES
The JAGUAR VXG is a general-purpose inverter whose operation is customized by frequency-basis function codes,
like conventional inverters. Under the speed-basis drive control, however, the control target is a motor speed, not a
frequency, so convert the frequency to the motor speed according to the following expression.
Motor speed (r/min) = 120 u Frequency (Hz) y Number of poles

5.2 Details of Function Codes
This section provides the details of the function codes. The descriptions are, in principle, arranged in the order of function
code groups and in numerical order. However, highly relevant function codes are collectively described where one of them
first appears.
5.2.1 Fundamental Functions
F00

F00 specifies whether to protect function code data (except F00) and digital reference data (such as frequency command

*Only F00 data can be modified with the keypad, while all other function codes cannot.
To change F00 data, simultaneous keying of "
+
" (from 0 to 1) or "
+
" (from 1 to 0) keys is required.
For similar purposes, WE-KP, a signal enabling editing of function code data from the keypad is provided as a terminal
command for digital input terminals. (Refer to the descriptions of E01 through E07, data = 19)
The relationship between the terminal command WE-KP and F00 data are as shown below.

• If you mistakenly assign the terminal command WE-KP, you no longer edit or modify function code data. In
such a case, temporarily turn this WE-KP-assigned terminal ON and reassign the WE-KP to a correct
command.
• WE-KP is only a signal that allows you to change function code data, so it does not protect the frequency
settings or PID speed command specified by the
and
keys.
Even when F00 = 1 or 3, function code data can be changed via the communications link.

Enable the voltage input to terminal [12] (0 to r10 VDC, maximum frequency obtained at r10
VDC).
Enable the current input to terminal [C1] (+4 to +20 mA DC, maximum frequency obtained at +20
mA DC). (SW5 on the control PCB should be turned to the C1 side (factory default).)
Enable the sum of voltage (0 to r10 VDC) and current inputs (+4 to +20 mA DC) given to terminals
[12] and [C1], respectively. See the two items listed above for the setting range and the value
required for maximum frequencies. (SW5 on the control PCB should be turned to the C1 side
(factory default).)
Note: If the sum exceeds the maximum frequency (F03), the maximum frequency will apply.
Enable the voltage input to terminal [V2] (0 to ±10 VDC, maximum frequency obtained at ±10
VDC). (SW5 on the control circuit board should be turned to the V2 position (factory default).)
Enable UP and DOWN commands assigned to the digital input terminals.
The UP command (any of E01 to E07 = 17) and DOWN command (any of E01 to E07 = 18) should
be assigned to any of digital input terminals [X1] to [X7].
For details, refer to the descriptions of E01 through E07.
Enable
/
keys on the keypad (balanceless-bumpless switching available).
Enable a digital input interface card (option).
(For details, refer to the Digital Input Interface Card Instruction Manual.)
Enable the "Pulse train input" PIN command assigned to digital input terminal [X7] (E07 = 48), or a
PG interface card (option).

When any analog input (voltage input to terminals [12] and [V2], or current input to terminal [C1]) is selected by F01, it
is possible to arbitrarily specify the reference frequency by multiplying the gain and adding the bias. The polarity can be
selected and the filter time constant and offset can be adjusted.

down the
/
key changes data in the least significant digit and generates a carry, while the cursor
remains in the least significant digit.
• While the least significant digit is blinking by pressing the
/
key, holding down the
key for
more than 1 second moves the cursor from the least significant digit to the most significant digit. Further
holding it down moves the cursor to the next lower digit. This cursor movement allows you to easily
move the cursor to the desired digit and change the data in higher digits.
• Setting F01 data to "8" enables the balanceless-bumpless switching. When the frequency command
source is switched to the keypad from any other source, the inverter inherits the current frequency that
has applied before switching, providing smooth switching and shockless running.

C33, C38, or C43 specifies a filter time constant for analog input voltage or current. Choose an appropriate value for the
time constant taking into account the response speed of the mechanical system since a large time constant slows down
the response. When the input voltage fluctuates due to noise, specify a larger time constant.

„ Gain and bias
If F01 = 3 (the sum of [12] + [C1] is enabled), the bias and gain are independently applied to each of the
voltage and current inputs given to terminals [12] and [C1], and the sum of the two values is applied as the
reference frequency.
In the case of unipolar input (terminal [12] with C35 = 1, terminal [C1], terminal [V2] with C45 = 1)
As shown in the graph above, the relationship between the analog input and the reference frequency specified by
frequency command 1 can arbitrarily be determined by points "A" and "B." Point "A" is defined by the combination of
the bias (F18) and its base point (C50); Point "B," by the combination of the gain (C32, C37 or C42) and its base point
(C34, C39 or C44).
The combination of C32 and C34 applies to terminal [12], that of C37 and C39, to [C1] (C1 function), and that of C42
and C44, to [C1] (V2 function).
Configure the bias (F18) and gain (C32, C37 or C42), assuming the maximum frequency as 100%, and the bias base
point (C50) and gain base point (C34, C39 or C44), assuming the full scale (10 VDC or 20 mA DC) of analog input as
100%.
• The analog input less than the bias base point (C50) is limited by the bias value (F18).
• Specifying that the data of the bias base point (C50) is equal to or greater than that of each gain base point
(C34, C39 or C44) will be interpreted as invalid, so the inverter will reset the reference frequency to 0 Hz.
Example: Setting the bias, gain and their base points when the reference frequency 0 to 60 Hz follows the analog input
of 1 to 5 VDC to terminal [12] (in frequency command 1).
(Point A)
To set the reference frequency to 0 Hz for an analog input being at 1 V, set the bias to 0% (F18 = 0). Since 1 V is the
bias base point and it is equal to 10% of 10 V (full scale of terminal [12]), set the bias base point to 10% (C50 = 10).
(Point B)
To make the maximum frequency equal to the reference frequency for an analog input being at 5 V, set the gain to
100% (C32 = 100). Since 5 V is the gain base point and it is equal to 50% of 10 V (full scale of terminal [12]), set the
gain base point to 50% (C34 = 50).
The setting procedure for specifying a gain or bias alone without changing any base points is the same as that
of IMO standard inverters of VXM & VXSM series, etc.
5-31
In the case of bipolar input (terminal [12] with C35 = 0, terminal [V2] with C45 = 0)
Setting C35 and C45 data to "0" enables terminal [12] and [V2] to be used for bipolar input (-10 V to +10 V)
respectively.
When both F18 (Bias) and C50 (Bias base point) are set to "0," the negative and positive voltage inputs produce
reference frequencies symmetric about the origin point as shown below.

Configuring F18 (Bias) and C50 (Bias base point) to specify an arbitrary value (Points A1, A2, and A3) gives

„ Selecting the pulse train input format (d59)
A pulse train in the format selected by the function code d59 can give a frequency command to the inverter. Three types
of formats are available; the pulse train sign/pulse train input, the forward rotation pulse/reverse rotation pulse, and the
A and B phases with 90 degree phase difference. If no optional PG interface card is mounted, the inverter ignores the
setting of the function code d59 and accepts only the pulse train sign/pulse train input.
The table below lists pulse train formats and their operations.

• When function code F02 = 0 or 1, the "Run forward" FWD and "Run reverse" REV terminal commands must
be assigned to terminals [FWD] and [REV], respectively.
• When the FWD or REV is ON, the F02 data cannot be changed.
• When changing terminal command assignments to terminals [FWD] and [REV] from commands other than
the FWD and REV to the FWD or REV with F02 being set to "1," be sure to turn the target terminal OFF
beforehand; otherwise, the motor may unintentionally rotate.
„ 3-wire operation with external input signals (digital input terminal commands)
The default setting of the FWD and REV are 2-wire. Assigning the terminal command HLD self-holds the forward
FWD or reverse REV run command, to enable 3-wire inverter operation. Short-circuiting the HLD-assigned terminal
and [CM] (i.e., when HLD is ON) self-holds the first FWD or REV at its rising edge. Turning the HLD OFF releases
the self-holding. When no HLD is assigned, 2-wire operation involving only FWD and REV takes effect.
For details about HLD, refer to E01 to E07 (data = 6).

In addition to the run command sources described above, higher priority command sources including remote and local

Maximum Frequency 1
- Data setting range: 25.0 to 500.0 (Hz)
• For MT- and VT-mode inverters, set the maximum frequency at 120 Hz or below.
• Under vector control with speed sensor, set the maximum frequency at 200 Hz or below, and under vector
control without speed sensor, at 120 Hz or below.
• If a setting exceeding the maximum setting value (e.g., 500 Hz) is made, the reference speed and analog
output (FMA) will be based on the full scale/reference value (10V/500 Hz). However, the frequency is
internally limited. Even if 10 V is inputted, the frequency 500 Hz will be internally limited to 200 Hz.
FUNCTION CODES
F03 specifies the maximum frequency to limit the output frequency. Specifying the maximum frequency exceeding the
rating of the equipment driven by the inverter may cause damage or a dangerous situation. Make sure that the maximum
frequency setting matches the equipment rating.
Chap. 5
F03
The inverter can easily accept high-speed operation. When changing the speed setting, carefully check the
specifications of motors or equipment beforehand.
Otherwise injuries could occur.
Modifying F03 data to allow a higher reference frequency requires also changing F15 data specifying a

Set "0" or the rated voltage printed on the nameplate labeled on the motor.
- If F05 = 0, the rated voltage at base frequency is determined by the power source of the inverter. The output voltage
will fluctuate in line with the input voltage fluctuation.
- If F05 = an arbitrary value other than 0, the inverter automatically keeps the output voltage constant in line with the
setting. When any of the auto torque boost, auto energy saving, etc. is enabled, the F05 data should be equal to the
rated voltage of the motor.
In vector control, current feedback control is performed. In the current feedback control, the current is
controlled with the difference between the motor induced voltage and the inverter output voltage. For a proper
control, the inverter output voltage should be sufficiently higher than the motor induced voltage. Generally, the
voltage difference is about 20 V for 200 V class series, about 40 V for 400 V class series.
The voltage the inverter can output is at the same level as the inverter input voltage. Configure these voltages
correctly in accordance with the motor specifications.
When enabling the vector control without speed sensor using a general-purpose motor, set the F05 (Rated
Voltage at Base Frequency 1) data at the rated voltage of the motor. The voltage difference described above is
specified by function code P56 (Induced voltage factor under vector control). Generally, there is no need to
modify the initial setting.

Upon detection of overload conditions of the motor, the inverter shuts down its output and issues a motor overload
alarm O to protect motor 1.

Even if you need only the overload early warning, set these characteristics data to these function codes.

If F10 is set to "2," changes of the output frequency do not affect the cooling effect. Therefore, the overload detection
level (F11) remains constant.

„ Overload detection level (F11)
Data setting range: 1 to 135% of the rated current (allowable continuous drive current) of the inverter
In general, set the F11 data to the allowable continuous current of motor when driven at the base frequency (i.e. 1.0 to
1.1 times of the rated current of the motor.)
To disable the electronic thermal overload protection, set the F11 data to "0.00."
Data setting range: 0.5 to 75.0 (minutes)
„ Thermal time constant (F12)
F12 specifies the thermal time constant of the motor. If the current of 150% of the overload detection level specified by
F11 flows for the time specified by F12, the electronic thermal overload protection becomes activated to detect the
motor overload. The thermal time constant for general-purpose motors including Fuji motors is approx. 5 minutes for
motors of 22 kW or below and 10 minutes for motors of 30 kW or above by factory default.
(Example) When the F12 data is set at 5 minutes
The actual time required for issuing a motor overload alarm tends to be shorter than the specified value, taking into
account the time period from when the output current exceeds the rated current (100%) until it reaches 150% of the
overload detection level.

If you enable the "Restart mode after momentary power failure" (Function code F14 = 3, 4, or 5), the inverter
automatically restarts the motor running when the power is recovered. Design the machinery or equipment so that
human safety is ensured after restarting.
Otherwise an accident could occur.
„ Restart mode after momentary power failure (Basic operation with auto search disabled)
The inverter recognizes a momentary power failure upon detecting the condition that DC link bus voltage goes below
the undervoltage detection level, while the inverter is running. If the load of the motor is light and the duration of the
momentary power failure is extremely short, the voltage drop may not be great enough for a momentary power failure
to be recognized, and the motor may continue to run uninterrupted.
Upon recognizing a momentary power failure, the inverter enters the restart mode (after a recovery from momentary
power failure) and prepares for restart. When power is restored, the inverter goes through an initial charging stage and
enters the ready-to-run state. When a momentary power failure occurs, the power supply voltage for external circuits
such as relay sequence circuits may also drop so as to turn the run command OFF. In consideration of such a situation,
the inverter waits 2 seconds for a run command input after the inverter enters a ready-to-run state. If a run command is
received within 2 seconds, the inverter begins the restart processing in accordance with the F14 data (Mode selection).
If no run command has been received within 2-second wait period, the inverter cancels the restart mode (after a
recovery from momentary power failure) and needs to be started again from the ordinary starting frequency. Therefore,
ensure that a run command is entered within 2 seconds after a recovery of power, or install a mechanical latch relay.
When run commands are entered via the keypad, the above operation is also necessary for the mode (F02 = 0) in which
the rotational direction is determined by the terminal command, FWD or REV. In the modes where the rotational
direction is fixed (F02 = 2 or 3), it is retained inside the inverter so that the restart will begin as soon as the inverter
enters the ready-to-run state.
• When the power is restored, the inverter will wait 2 seconds for input of a run command. However, if the
allowable momentary power failure time (H16) elapses after the power failure was recognized, even within
the 2 seconds, the restart time for a run command is canceled. The inverter will start operation in the normal
starting sequence.
• If the "Coast to a stop" terminal command BX is entered during the power failure, the inverter gets out of the
restart mode and enters the normal running mode. If a run command is entered with power supply applied,
the inverter will start from the normal starting frequency.
• The inverter recognizes a momentary power failure by detecting an undervoltage condition whereby the
voltage of the DC link bus goes below the lower limit. In a configuration where a magnetic contactor is
installed on the output side of the inverter, the inverter may fail to recognize a momentary power failure
because the momentary power failure shuts down the operating power of the magnetic contactor, causing the
contactor circuit to open. When the contactor circuit is open, the inverter is cut off from the motor and load,
and the voltage drop in the DC link bus is not great enough to be recognized as a power failure. In such an
event, restart after a recovery from momentary power failure does not work properly as designed. To solve
this, connect the interlock command IL line to the auxiliary contact of the magnetic contactor, so that a
momentary power failure can sure be detected. For details, refer to the descriptions of E01 through E07.

Description
No momentary power failure has occurred.
A momentary power failure has occurred. (Restart after a momentary power failure enabled)
During a momentary power failure, the motor slows down. After power is restored, the inverter restarts at the frequency
just before the momentary power failure. Then, the current limiting function works and the output frequency of the
inverter automatically decreases. When the output frequency matches the motor speed, the motor accelerates up to the
original output frequency. See the figure below. In this case, the instantaneous overcurrent limiting must be enabled
(H12 = 1).

• Auto-restarting after momentary power failure IPF
„ Restart mode after momentary power failure (Basic operation with auto search enabled)
Auto search for idling motor speed will become unsuccessful if it is done while the motor retains residual voltage. It is,
therefore, necessary to leave the motor for the time (auto search delay time) enough to discharge the residual voltage.
The delay time is specified by H46 (Starting Mode (Auto search delay time 2)).
The inverter will not start unless the time specified by H46 has elapsed, even if the starting conditions are satisfied. (
For details, refer to H09 and d67.)
FUNCTION CODES
This output signal is ON during the period after the occurrence of momentary power failure until the completion of
restart (the output has reached the reference frequency). When the IPF is ON, the motor slows down, so perform
necessary operations. ( For details about IPF, refer to E20 through E24 and E27 (data = 6).)
• To use auto search for idling motor speed, it is necessary to tune the inverter beforehand.
• When the estimated speed exceeds the maximum frequency or the upper limit frequency, the inverter
disables auto search and starts running the motor with the maximum frequency or the upper limit frequency,
whichever is lower.
• During auto search, if an overcurrent or overvoltage trip occurs, the inverter restarts the suspended auto
search.
• Perform auto search at 60 Hz or below.
• Note that auto search may not fully provide the expected/designed performance depending on conditions
including the load, motor parameters, power cable length, and other externally determined events.
„ Restart mode after momentary power failure (Allowable momentary power failure time) (H16)
H16 specifies the maximum allowable duration (0.0 to 30.0 seconds) from an occurrence of a momentary power failure
(undervoltage) until the inverter is to be restarted. Specify the coast-to-stop time which the machine system and facility
can tolerate.
If the power is restored within the specified duration, the inverter restarts in the restart mode specified by F14. If not,
the inverter recognizes that the power has been shut down so that the inverter does not apply the restart mode and starts
normal running.

If H16 (Allowable momentary power failure time) is set to "999," restart will take place until the DC link bus voltage
drops down to the allowable voltage for restart after a momentary power failure (50 V for 200 V class series and 100 V
for 400 V class series). If the DC link bus voltage drops below the allowable voltage, the inverter recognizes that the
power has been shut down so that it does not restart but starts (normal starting).

The time required from when the DC link bus voltage drops from the threshold of undervoltage until it reaches
the allowable voltage for restart after a momentary power failure, greatly varies depending on the inverter
capacity, the presence of options, and other factors.
„ Restart mode after momentary power failure (Restart time) (H13)
H13 specifies the time period from momentary power failure occurrence until the inverter reacts for restarting process.
If the inverter starts the motor while motor’s residual voltage is still in a high level, a large inrush current may flow or
an overvoltage alarm may occur due to an occurrence of temporary regeneration. For safety, therefore, it is advisable to
set H13 to a certain level so that the restart will take place only after the residual voltage has dropped to a low level.
Note that even when power is restored, restart will not take place until the restart time (H13) has elapsed.
Factory default: By factory default, H13 is set to the value suitable for the standard motor (see Table B in Section 5.1
"Function Code Tables"). Basically, it is not necessary to change H13 data. However, if the long restart time causes the
flow rate of the pump to overly decrease or causes any other problem, you might as well reduce the setting to about a
half of the default value. In such a case, make sure that no alarm occurs.
Function code H13 (Restart mode after momentary power failure -- Restart time) also applies to the switching
operation between line and inverter (refer to the descriptions of E01 through E07).
5-47
„ Restart mode after momentary power failure (Frequency fall rate) (H14)
During restart after a momentary power failure, if the inverter output frequency and the idling motor speed cannot be
harmonized with each other, an overcurrent will flow, activating the overcurrent limiter. If it happens, the inverter
automatically reduces the output frequency to match the idling motor speed according to the reduction rate (Frequency
fall rate: Hz/s) specified by H14.

(The PI constant is prefixed inside the inverter.)
If the frequency fall rate is too high, regeneration may take place at the moment the motor rotation matches
the inverter output frequency, causing an overvoltage trip. On the contrary, if the frequency fall rate is too
low, the time required for the output frequency to match the motor speed (duration of current limiting action)
may be prolonged, triggering the inverter overload prevention control.

„ Restart after momentary power failure (Continuous running level) (H15)
Continuity of running (P and I) (H92, H93)
FUNCTION CODES
• Trip after decelerate-to-stop
If a momentary power failure occurs when F14 is set to "2" (Trip after decelerate-to-stop), the inverter enters the control
sequence of the decelerate-to-stop when the DC link bus voltage drops below the continuous running level specified by
H15.
Under the decelerate-to-stop control, the inverter decelerates its output frequency keeping the DC link bus voltage
constant using the PI processor. P (proportional) and I (integral) components of the PI processor are specified by H92
and H93, respectively.
For normal inverter operation, it is not necessary to modify data of H15, H92 or H93.
• Continue to run
If a momentary power failure occurs when F14 is set to "3" (Continue to run), the inverter enters the control sequence
of the continuous running when the DC link bus voltage drops below the continuous running level specified by H15.
Under the continuous running control, the inverter continues to run keeping the DC link bus voltage constant using the
PI processor.
P (proportional) and I (integral) components of the PI processor are specified by H92 and H93, respectively.

Even if you select "Trip after decelerate-to-stop" or "Continue to run," the inverter may not be able to do so
when the load's inertia is small or the load is heavy, due to undervoltage caused by a control delay. In such a
case, when "Trip after decelerate-to-stop" is selected, the inverter allows the motor to coast to a stop; when
"Continue to run" is selected, the inverter saves the output frequency being applied when the undervoltage
alarm occurred and restarts at the saved frequency after a recovery from the momentary power failure.
When the input power voltage for the inverter is high, setting the continuous running level high makes the
control more stable even if the load's inertia is relatively small. Raising the continuous running level too high,
however, might cause the continuous running control activated even during normal operation.
When the input power voltage for the inverter is extremely low, continuous running control might be activated
even during normal operation, at the beginning of acceleration or at an abrupt change in load. To avoid this,
lower the continuous running level. Lowering it too low, however, might cause undervoltage that results from
voltage drop due to a control delay.
Before you change the continuous running level, make sure that the continuous running control will be
performed properly, by considering the fluctuations of the load and the input voltage.

If the motor enters a decelerate-to-stop operation by turning OFF the run command or by decreasing the reference

Turning the DCBRK command ON even when the inverter is in a stopped state activates the DC braking. This
feature allows the motor to be excited before starting, resulting in smoother acceleration (quicker build-up of
acceleration torque) (under V/f control).
When vector control without/with speed sensor is selected, use the pre-exciting feature for establishing the
magnetic flux. ( For details, refer to H84.)
In general, DC braking is used to prevent the motor from running by inertia during the stopping process. Under
vector control with speed sensor, however, zero speed control will be more effective for applications where
load is applied to the motor even in a stopped state.
If the zero speed control continues for a long time, the motor may slightly rotate due to a control error. To fix
the motor shaft, use the servo-lock function. ( For details, refer to J97.)
In general, specify data of function code F20 at a value close to the rated slip frequency of motor. If you set it
at an extremely high value, control may become unstable and an overvoltage alarm may result in some cases.

Under V/f control
At the startup of an inverter, the initial output frequency is equal to the starting frequency 1 specified by F23. The
inverter stops its output when the output frequency reaches the stop frequency specified by F25.
Set the starting frequency to a level at which the motor can generate enough torque for startup. Generally, set the
motor's rated slip frequency as the starting frequency.
In addition, F24 specifies the holding time for the starting frequency 1 in order to compensate for the delay time for the
establishment of a magnetic flux in the motor. F39 specifies the holding time for the stop frequency in order to stabilize
the motor speed at the stop of the inverter.
Data setting range: 0.0 to 60.0 (Hz)
„ Starting frequency 1 (F23)

the inverter stops at 0.1 Hz.
„ Stop frequency (Holding time) (F39)
Data setting range: 0.00 to 10.00 (s)
F39 specifies the holding time for the stop frequency.
If the starting frequency is lower than the stop frequency, the inverter will not output any power as long as the
reference frequency does not exceed the stop frequency.
Under vector control without/with speed sensor
At the startup, the inverter first starts at the “0” speed and accelerates to the starting frequency according to the
specified acceleration time. After holding the starting frequency for the specified period, the inverter again accelerates
to the reference speed according to the specified acceleration time.
The inverter stops its output when the detected speed or reference one (specified by F38) reaches the stop frequency
specified by F25.
In addition, F24 specifies the holding time for the starting frequency 1 in order to compensate for the delay time for the
establishment of a magnetic flux in the motor. F39 specifies the holding time for the stop frequency in order to stabilize
the motor speed at the stop of the inverter.

F38 specifies whether the inverter judges when to shutdown its output by the detected speed or reference speed.
Although the inverter generally judges it by the detected speed, if a load exceeding the inverter capability such as
external excess load is applied, the inverter may not stop because the motor may not stop normally and the detected
speed may not reach the stop frequency level. If F38 data is set to "1" (reference speed), the inverter can stop without
fail because the reference speed reaches the stop frequency level even if the detected speed does not.

Specifying a too low carrier frequency will cause the output current waveform to have a large amount of
ripples. As a result, the motor loss increases, causing the motor temperature to rise. Furthermore, the large
amount of ripples tends to cause a current limiting alarm. When the carrier frequency is set to 1 kHz or below,
therefore, reduce the load so that the inverter output current comes to be 80% or less of the rated current.
When a high carrier frequency is specified, the temperature of the inverter may rise due to a surrounding
temperature rise or an increase of the load. If it happens, the inverter automatically decreases the carrier
frequency to prevent the inverter overload alarm OX . With consideration for motor noise, the automatic
reduction of carrier frequency can be disabled. Refer to the description of H98.
It is recommended to set the carrier frequency at 5 kHz or above under vector control without/with speed
sensor. DO NOT set it at 1 kHz or below.
„ Motor Sound (Tone) (F27)
F27 changes the motor running sound tone (only for motors under V/f control). This setting is effective when the carrier
frequency specified by function code F26 is 7 kHz or lower. Changing the tone level may reduce the high and harsh
running noise from the motor.
If the tone level is set too high, the output current may become unstable, or mechanical vibration and noise may
increase.
Also, this function code may not be very effective for certain types of motor.

„ V/f characteristics
The JAGUAR VXG series of inverters offers a variety of V/f patterns and torque boosts, which include V/f patterns
suitable for variable torque load such as general fans and pumps and for constant torque load (including special pumps
requiring high starting torque). Two types of torque boosts are available: manual and automatic.
Variable torque V/f pattern (F37 = 0)
Linear V/f pattern (F37 = 1)
5-55
When the variable torque V/f pattern is selected (F37 = 0 or 3), the output voltage may be low at a low
frequency zone, resulting in insufficient output torque, depending on the characteristics of the motor and load.
In such a case, it is recommended to increase the output voltage at the low frequency zone using the
non-linear V/f pattern.
Recommended value: H50 = 1/10 of the base frequency
H51 = 1/10 of the voltage at base frequency
• Manual torque boost (F09)
In torque boost using F09, constant voltage is added to the basic V/f pattern, regardless of the load. To secure a
sufficient starting torque, manually adjust the output voltage to optimally match the motor and its load by using F09.
Specify an appropriate level that guarantees smooth start-up and yet does not cause over-excitation at no or light load.
Torque boost per F09 ensures high driving stability since the output voltage remains constant regardless of the load
fluctuation.
Specify the F09 data in percentage to the rated voltage at base frequency 1 (F05). At factory shipment, F09 is preset to a
level that assures approx. 100% of starting torque.
• Specifying a high torque boost level will generate a high torque, but may cause overcurrent due to
over-excitation at no load. If you continue to drive the motor, it may overheat. To avoid such a situation,
adjust torque boost to an appropriate level.
• When the non-linear V/f pattern and the torque boost are used together, the torque boost takes effect below
the frequency on the non-linear V/f pattern’s point.

Data setting range: 0.0 to 20.0 (%) (100%/Rated voltage at base frequency)

„ Torque boost
• Auto torque boost
If the auto torque boost is selected, the inverter automatically optimizes the output voltage to fit the motor with its load.
Under light load, the inverter decreases the output voltage to prevent the motor from over-excitation. Under heavy load,
it increases the output voltage to increase the output torque of the motor.
• Since this function relies also on the characteristics of the motor, set the base frequency 1 (F04), the rated
voltage at base frequency 1 (F05), and other pertinent motor parameters (P01 through P03 and P06 through
P99) in line with the motor capacity and characteristics, or else perform auto-tuning (P04).
• When a special motor is driven or the load does not have sufficient rigidity, the maximum torque might
decrease or the motor operation might become unstable. In such cases, do not use auto torque boost but
choose manual torque boost per F09 (F37 = 0 or 1).
F codes
„ Auto energy saving operation (H67)
If the auto energy saving operation is enabled, the inverter automatically controls the supply voltage to the motor to
minimize the total power loss of motor and inverter. (Note that this feature may not be effective depending upon the
motor or load characteristics. Check the advantage of energy saving before you actually apply this feature to your
machinery.)
You can select whether applying this feature to constant speed operation only or applying to constant speed operation
and accelerating/decelerating operation.

base frequency, the auto energy saving operation will be invalid.
• Since this function relies also on the characteristics of the motor, set the base frequency 1 (F04), the rated
voltage at base frequency 1 (F05), and other pertinent motor parameters (P01 through P03 and P06 through

„ Torque limiter (Frequency increment limit for braking) (H76)
Data setting range: 0.0 to 500.0 (Hz)
H76 specifies the increment limit of the frequency in limiting torque for braking. The factory default is 5.0 Hz. If the
increasing frequency during braking reaches the limit value, the torque limiters no longer function, resulting in an
overvoltage trip. Such a problem may be avoided by increasing the setting of H76.
The torque limiter and current limiter are very similar function each other. If both are activated concurrently,
they may conflict each other and cause hunting in the system. Avoid concurrent activation of these limiters.
Under vector control without/with speed sensor
If the inverter’s output torque exceeds the specified levels of the torque limiters (F40, F41, E16, E17, and E61 to E63),
the inverter controls the speed regulator's output (torque command) in speed control or a torque command in torque

• If the value of torque limiter A is less than that of torque limiter B, torque limiter A
applies to both the upper and lower limits.
• Selecting the "Upper/lower torque limits" may cause reciprocating oscillation between
the upper and lower limit values, depending upon a small difference between the upper
and lower limits, a slow response from the speed control sequence, and other
conditions.

Although the data setting range for F40, F41, E16, and E17 is from positive to negative values (–300% to
+300%), specify positive values in practice except when the "Upper/lower torque limits" (H75 = 2) is selected.
If a negative value is specified, the inverter interprets it as an absolute value.
The torque limiter determined depending on the overload current actually limits the torque current output.
Therefore, the torque current output is automatically limited at a value lower than 300%, the maximum setting
value.
„ Analog torque limit values (E61 to E63)
The torque limit values can be specified by analog inputs through terminals [12], [C1], and [V2] (voltage or current).
Set E61, E62, and E63 (Terminal [12] Extended Function, Terminal [C1] Extended Function, and Terminal [V2]

If the same setting is made for different terminals, the priority order is E61>E62>E63.
„ Torque limiter levels specified via communications link (S10, S11)
The torque limiter levels can be changed via the communications link. Function codes S10 and S11 exclusively
reserved for the communications link respond to function codes F40 and F41.
„ Switching torque limiters
The torque limiters can be switched by the function code setting and the terminal command TL2/TL1 ("Select torque
limiter level 2/1") assigned to any of the digital input terminals.
To assign the TL2/TL1 as the terminal function, set any of E01 through E07 to "14." If no TL2/TL1 is assigned, torque
limiter levels 1-1 and 1-2 (F40 and F41) take effect by default.

„ V/f control with slip compensation inactive
Under this control, the inverter controls a motor with the voltage and frequency according to the V/f pattern specified
by function codes. This control disables all automatically controlled features such as the slip compensation, so no
unpredictable output fluctuation, enabling stable operation with constant output frequency.
„ V/f control with slip compensation active
Applying any load to an induction motor causes a rotational slip due to the motor characteristics, decreasing the motor
rotation. The inverter’s slip compensation function first presumes the slip value of the motor based on the motor torque
generated and raises the output frequency to compensate for the decrease in motor rotation. This prevents the motor
from decreasing the rotation due to the slip.
That is, this function is effective for improving the motor speed control accuracy.

„ Dynamic torque vector control
To get the maximal torque out of a motor, this control calculates the motor torque for the load applied and uses it to
optimize the voltage and current vector output.
Selecting this control automatically enables the auto torque boost and slip compensation function.
This control is effective for improving the system response to external disturbances such as load fluctuation, and the
motor speed control accuracy.
Note that the inverter may not respond to a rapid load fluctuation since this control is an open-loop V/f control that does
not perform the current control, unlike the vector control. The advantages of this control include larger maximum
torque per output current than that the vector control.
„ V/f control with speed sensor
Applying any load to an induction motor causes a rotational slip due to the motor characteristics, decreasing the motor
rotation. Under V/f control with speed sensor, the inverter detects the motor rotation using the encoder mounted on the
motor shaft and compensates for the decrease in slip frequency by the PI control to match the motor rotation with the
commanded speed. This improves the motor speed control accuracy.
„ Dynamic torque vector control with speed sensor
The difference from the "V/f control with speed sensor" stated above is to calculate the motor torque for the load
applied and use it to optimize the voltage and current vector output for getting the maximal torque out of a motor.
This control is effective for improving the system response to external disturbances such as load fluctuations, and the
motor speed control accuracy.
„ Vector control without speed sensor
This control estimates the motor speed based on the inverter's output voltage and current to use the estimated speed for
speed control. In addition, it decomposes the motor drive current into the exciting and torque current components, and
controls each of those components in vector. No PG (pulse generator) interface card is required. It is possible to obtain
the desired response by adjusting the control constants (PI constants) using the speed regulator (PI controller).
Since this control controls the motor current, it is necessary to secure some voltage margin between the voltage that the
inverter can output and the induced voltage of the motor, by keeping the former lower than the latter.
Although the voltage of the general-purpose motor has usually been adjusted to match the commercial power, keeping
the motor terminal voltage low is necessary in order to secure the voltage margin. If the motor is driven under this
control with the motor terminal voltage being kept low, however, the rated torque cannot be obtained even when the
rated current originally specified for the motor is applied. To secure the rated torque, therefore, it is necessary to use a
motor with higher rated current. (This also applies to the vector control with speed sensor.)
This control is not available in MT-mode inverters, so do not set F42 data to "5" for those inverters.
„ Vector control with speed sensor
This control requires an optional PG (pulse generator) and an optional PG interface card to be mounted on a motor shaft
and an inverter, respectively. The inverter detects the motor's rotational position and speed from PG feedback signals
and uses them for speed control. In addition, it decomposes the motor drive current into the exciting and torque current
components, and controls each of components in vector.
The desired response can be obtained by adjusting the control constants (PI constants) and using the speed regulator (PI
controller). This control enables the speed control with higher accuracy and quicker response than the vector control
without speed sensor.
Since slip compensation, dynamic torque vector control, and vector control without/with speed sensor use
parameters, the following conditions should be satisfied; otherwise, full control performance may not be
obtained.
• A single motor should be controlled per inverter.
• Motor parameters P02, P03, P06 to P23, P55 and P56 are properly configured. Or, auto-tuning (P04) is
performed.
• The capacity of the motor to be controlled should be two or more ranks lower than that of the inverter under
the dynamic torque vector control; it should be the same as the inverter under the vector control without/with
speed sensor. Otherwise, the inverter may not control the motor due to decrease of the current detection
resolution.
• The wiring distance between the inverter and motor should be 50 m or less. If it is longer, the inverter may not
control the motor due to leakage current flowing through stray capacitance to the ground or between wires.
Especially, small capacity inverters whose rated current is also small may be unable to control the motor
correctly even when the wiring is less than 50 m. In that case, make the wiring length as short as possible or
use a wire with small stray capacitance (e.g., loosely-bundled cable) to minimize the stray capacitance.

Current Limiter (Mode selection, Level)
H12 (Instantaneous Overcurrent Limiting (Mode selection))
When the output current of the inverter exceeds the level specified by the current limiter (F44), the inverter
automatically manages its output frequency to prevent a stall and limit the output current.
The default setting is 160%, 145% and 130% for CT-, MT- and VT-mode inverters, respectively. (Once the CT, MT, or
VT mode is selected by F80, the current limit for each mode is automatically specified.)
If 160% (145% or 130%) or over of overcurrent instantaneously flows and the output frequency decreases by this
current limit that is undesired, consider increasing the current limit level.
If F43 = 1, the current limiter is enabled only during constant speed operation. If F43 = 2, the current limiter is enabled
during both of acceleration and constant speed operation. Choose F43 = 1 if you need to run the inverter at full
capability during acceleration and to limit the output current during constant speed operation.

„ Instantaneous Overcurrent Limiting (Mode selection) (H12)
H12 specifies whether the inverter invokes the current limit processing or enters the overcurrent trip when its output
current exceeds the instantaneous overcurrent limiting level. Under the current limit processing, the inverter
immediately turns OFF its output gate to suppress the further current increase and continues to control the output
frequency.

If any problem occurs in use of the equipment or machine is expected when the motor torque temporarily drops during
current limiting processing, it is necessary to cause an overcurrent trip (H12 = 0) and actuate a mechanical brake at the
same time.
X
• Since the current limit operation with F43 and F44 is performed by software, it may cause a delay in control.
If you need a quick response current limiting, also enable the instantaneous overcurrent limiting with H12.
• If an excessive load is applied when the current limiter operation level is set extremely low, the inverter will
rapidly lower its output frequency. This may cause an overvoltage trip or dangerous turnover of the motor
rotation due to undershooting. Depending on the load, extremely short acceleration time may activate the
current limiting to suppress the increase of the inverter output frequency, causing the system oscillation
(hunting) or activating the inverter overvoltage trip (alarm
). When specifying the acceleration time,
therefore, you need to take into account machinery characteristics and moment of inertia of the load.
• The torque limiter and current limiter are very similar function each other. If both are activated concurrently,
they may conflict each other and cause hunting in the system. Avoid concurrent activation of these limiters.
• The vector control itself contains the current control system, so it disables the current limiter specified by
F43 and F44, as well as automatically disabling the instantaneous overcurrent limiting (specified by H12).
Accordingly, the inverter causes an overcurrent trip when its output current exceeds the instantaneous
overcurrent limiting level.

Electronic Thermal Overload Protection for Braking Resistor
(Discharging capability, Allowable average loss and Resistance)
These function codes specify the electronic thermal overload protection feature for the braking resistor.
Set the discharging capability, allowable average loss and resistance to F50, F51 and F52, respectively. These values
are determined by the inverter and braking resistor models. For the discharging capability, allowable average loss and
resistance, refer to JAGUAR VXG User's Manual, Chapter 4 "SELECTING PERIPHERAL EQUIPMENT." The values
listed in the manual are for standard models and 10% ED models of the braking resistors which IMO can supply. If you
use a braking resistor of other manufacturer, confirm the corresponding values with the manufacturer, and set the
function codes accordingly.

Depending on the thermal marginal characteristics of the braking resistor, the electronic thermal overload
protection feature may act so that the inverter issues the overheat protection alarm GEK even if the actual
temperature rise is not large enough. If it happens, review the relationship between the performance index of
the braking resistor and settings of related function codes.
The standard models of braking resistor can output temperature detection signal for overheat. Assign an
"Enable external alarm trip" terminal command THR to any of digital input terminals [X1] to [X7], [FWD]
and [REV] and connect that terminal and its common terminal to braking resistor's terminals 2 and 1.
Calculating the discharging capability and allowable average loss of the braking resistor and configuring the
function code data
When using any non-Fuji braking resistor, inquire of the resistor manufacturer about the resistor rating and then
configure the related function codes.
The calculation procedures for the discharging capability and allowable average loss of the braking resistor differ
depending on the application of the braking load as shown below.
- Applying braking load during deceleration
In usual deceleration, the braking load decreases as the speed slows down. In the deceleration with constant torque, the
braking load decreases in proportion to the speed. Use Expressions (1) and (3) given below.
- Applying braking load during running at a constant speed
Different from during deceleration, in applications where the braking load is externally applied during running at a
constant speed, the braking load is constant. Use Expressions (2) and (4) given below.

Function codes E01 to E07, E98 and E99 allow you to assign commands to terminals [X1] to [X7], [FWD], and [REV]
which are general-purpose, programmable, digital input terminals.
These function codes may also switch the logic system between normal and negative to define how the inverter logic
interprets either ON or OFF status of each terminal. The default setting is normal logic system "Active ON." So,
explanations that follow are given in normal logic system "Active ON." The descriptions are, in principle, arranged in
the numerical order of assigned data. However, highly relevant signals are collectively described where one of them
first appears. Refer to the function codes in the "Related function codes" column, if any.
The JAGUAR VXG runs under V/f control, dynamic torque vector control, V/f control with speed sensor, dynamic
torque vector control with speed sensor, vector control without speed sensor, or vector control with speed sensor. Some
function codes apply exclusively to the specific drive control, which is indicated by letters Y (Applicable) and N (Not
applicable) in the "Drive control" column in the table given below. (Refer to page 5-2.)
• Ensure safety before modifying the function code settings.
Run commands (e.g., "Run forward" FWD), stop commands (e.g., "Coast to a stop" BX), and frequency change
commands can be assigned to digital input terminals. Depending upon the assignment states of those terminals,
modifying the function code setting may cause a sudden motor start or an abrupt change in speed.
• When the inverter is controlled with the digital input signals, switching run or frequency command sources with
the related terminal commands (e.g., SS1, SS2, SS4, SS8, Hz2/Hz1, Hz/PID, IVS, and LE) may cause a sudden
motor start or an abrupt change in speed.
An accident or physical injury may result.

Terminal function assignment and data setting
„ Coast to a stop -- BX (Function code data = 7)
Turning this terminal command ON immediately shuts down the inverter output so that the motor coasts to a stop
without issuing any alarms.
„ Reset alarm -- RST (Function code data = 8)
Turning this terminal command ON clears the ALM state--alarm output (for any fault). Turning it OFF erases the alarm
display and clears the alarm hold state.
When you turn the RST command ON, keep it ON for 10 ms or more. This command should be kept OFF for the
normal inverter operation.
„ Enable external alarm trip -- THR (Function code data = 9)
Turning this terminal command OFF immediately shuts down the inverter output (so that the motor coasts to a stop),
displays the alarm K, and outputs the alarm relay (for any fault) ALM. The THR command is self-held, and is reset
when an alarm reset takes place.
Use this alarm trip command from external equipment when you have to immediately shut down the inverter
output in the event of an abnormal situation in peripheral equipment.
„ Switch to commercial power for 50 Hz or 60 Hz -- SW50 and SW60 (Function code data = 15 and 16)
When an external sequence switches the motor drive power from the commercial line to the inverter, inputting the
terminal command SW50 or SW60 at the specified timing enables the inverter to start running the motor with the
current commercial power frequency, regardless of settings of the reference/output frequency in the inverter. A running
motor driven by commercial power is carried on into inverter operation. This command helps you smoothly switch the
motor drive power source, when the motor is being driven by commercial power, from the commercial power to the
inverter power.
For details, refer to the following table, the operation schemes, and an example of external circuit and its operation time
scheme on the following pages.

Operation Schemes
• When the motor speed remains almost the same during coast-to-stop:
FUNCTION CODES
• When the motor speed decreases significantly during coast-to-stop (with the current limiter activated):
Chap. 5
• Secure more than 0.1 second after turning ON the "Switch to commercial power" signal before turning ON a
run command.
• Secure more than 0.2 second of an overlapping period with both the "Switch to commercial power" signal
and run command being ON.
• If an alarm has been issued or BX has been ON when the motor drive source is switched from the
commercial power to the inverter, the inverter will not be started at the commercial power frequency and
will remain OFF. After the alarm has been reset or BX turned OFF, operation at the frequency of the
commercial power will not be continued, and the inverter will be started at the ordinary starting frequency.
If you wish to switch the motor drive source from the commercial line to the inverter, be sure to turn BX
OFF before the "Switch to commercial power" signal is turned OFF.
• When switching the motor drive source from the inverter to commercial power, adjust the inverter's
reference frequency at or slightly higher than that of the commercial power frequency beforehand, taking
into consideration the motor speed down during the coast-to-stop period produced by switching.
• Note that when the motor drive source is switched from the inverter to the commercial power, a high inrush
current will be generated, because the phase of the commercial power usually does not match the motor
speed at the switching. Make sure that the power supply and all the peripheral equipment are capable of
withstanding this inrush current.
• If you have enabled "Restart after momentary power failure" (F14 = 3, 4, or 5), keep BX ON during
commercial power driven operation to prevent the inverter from restarting after a momentary power failure.

Alternatively, you may use the integrated sequence by which some of the actions above are automatically
performed by the inverter itself. For details, refer to the description of ISW50 and ISW60.
„ Cancel PID control -- Hz/PID (Function code data = 20)

If the PID control is disabled with this command, the inverter runs the motor with the reference frequency manually set
by any of the multi-frequency, keypad, analog input, etc.

„ Switch normal/inverse operation -- IVS (Function code data = 21)
This terminal command switches the output frequency control between normal (proportional to the input value) and
inverse in analog frequency setting or under PID process control. To select the inverse operation, turn the IVS ON.

The normal/inverse switching operation is useful for air-conditioners that require switching between cooling
and heating. In cooling, the speed of the fan motor (output frequency of the inverter) is increased to lower the
temperature. In heating, it is reduced to lower the temperature. This switching is realized by this IVS terminal
command.

• When the inverter is driven by an external analog frequency command sources (terminals [12], [C1] and [V2]):
Switching normal/inverse operation can apply only to the analog frequency command sources (terminals [12], [C1] and
[V2]) in frequency command 1 (F01) and does not affect frequency command 2 (C30) or UP/DOWN control.
As listed below, the combination of the "Selection of normal/inverse operation for frequency command 1" (C53) and
the IVS terminal command determines the final operation.

case, the combination of the "PID control" (J01) or "Selection of normal/inverse operation for frequency command 1"
(C53) and the terminal command IVS determines the final operation as listed below.

When the process control is performed by the PID control facility integrated in the inverter, the IVS is used
to switch the PID processor output (reference frequency) between normal and inverse, and has no effect on
any normal/inverse operation selection of the manual frequency setting.
Refer to the descriptions of J01 through J19 and J56 through J62.
„ Universal DI -- U-DI (Function code data = 25)
Using U-DI enables the inverter to monitor digital signals sent from the peripheral equipment via an RS-485
communications link or a fieldbus option by feeding those signals to the digital input terminals. Signals assigned to the
universal DI are simply monitored and do not operate the inverter.
For an access to universal DI via the RS-485 or fieldbus communications link, refer to their respective Instruction
Manuals.
„ Force to stop -- STOP (Function code data = 30)
Turning this terminal command OFF causes the motor to decelerate to a stop in accordance with the H56 data
(Deceleration time for forced stop). After the motor stops, the inverter enters the alarm state with the alarm HU
displayed. ( Refer to the description of F07.)
„ Reset PID integral and differential components -- PID-RST (Function code data = 33)
Turning this terminal command ON resets the integral and differential components of the PID processor. ( Refer to
the descriptions of J01 through J19 and J56 through J62.)
„ Hold PID integral component -- PID-HLD (Function code data = 34)
Turning this terminal command ON holds the integral components of the PID processor. ( Refer to the descriptions
of J01 through J19 and J56 through J62.)
5-73
„ Enable integrated sequence to switch to commercial power (50 Hz) and (60 Hz) -- ISW50 and ISW60
(Function code data = 40 and 41)
With the terminal command ISW50 or ISW60 assigned, the inverter controls the magnetic contactor that switches the
motor drive source between the commercial power and the inverter output according to the integrated sequence.
This control is effective when not only ISW50 or ISW60* has been assigned to the input terminal but also the SW88
and SW52-2 signals have been assigned to the output terminals. (It is not essential to assign the SW52-1 signal.)
* The ISW50 or ISW60 should be selected depending upon the frequency of the commercial power; the former for 50
Hz and the latter for 60 Hz.
For details of these commands, refer to the circuit diagrams and timing schemes given below.

Sequence (upon occurrence of an alarm)
Keep inverter-operation (Stop due to alarm.)
Automatically switch to commercial-power operation
• The sequence operates normally also even when SW52-1 is not used and the main power of the inverter is
supplied at all times.
• Using SW52-1 requires connecting the input terminals [R0] and [T0] for an auxiliary control power. Without
the connection, turning SW52-1 OFF loses also the control power.
• The sequence operates normally even if an alarm occurs in the inverter except when the inverter itself is
broken. Therefore, for a critical facility, be sure to install an emergency switching circuit outside the inverter.
• Turning ON both the magnetic contactor MC (88) at the commercial-power side and the MC (52-2) at the
inverter output side at the same time supplies main power mistakenly from the output (secondary) side of the
inverter, which may damage the inverter. To prevent it, be sure to set up an interlocking logic outside the
inverter.

Terminal [Y5A/C] and [30A/B/C] Function (Relay output)
E20 through E24 and E27 assign output signals (listed on the next page) to general-purpose, programmable output
terminals [Y1], [Y2], [Y3], [Y4], [Y5A/C] and [30A/B/C]. These function codes can also switch the logic system
between normal and negative to define the property of those output terminals so that the inverter logic can interpret
either the ON or OFF status of each terminal as active. The factory default settings are "Active ON."
Terminals [Y1], [Y2], [Y3] and [Y4] are transistor outputs and terminals [Y5A/C] and [30A/B/C] are relay contact
outputs. In normal logic, if an alarm occurs, the relay will be energized so that [30A] and [30C] will be closed, and
[30B] and [30C] opened. In negative logic, the relay will be deenergized so that [30A] and [30C] will be opened, and
[30B] and [30C] closed. This may be useful for the implementation of failsafe power systems.
• When a negative logic is employed, all output signals are active (e.g. an alarm would be recognized) while
the inverter is powered OFF. To avoid causing system malfunctions by this, interlock these signals to keep
them ON using an external power supply. Furthermore, the validity of these output signals is not guaranteed
for approximately 1.5 seconds (for 22 kW or below) or 3 seconds (for 30 kW or above) after power- ON, so
introduce such a mechanism that masks them during the transient period.
5-77
• Terminals [Y5A/C] and [30A/B/C] use mechanical contacts that cannot stand frequent ON/OFF switching.
Where frequent ON/OFF switching is anticipated (for example, limiting a current by using signals subjected
to inverter output limit control such as switching to commercial power line or direct-on-line starting), use
transistor outputs [Y1], [Y2], [Y3] and [Y4] instead.
The service life of a relay is approximately 200,000 times if it is switched ON and OFF at one-second
intervals.
The table below lists functions that can be assigned to terminals [Y1], [Y2], [Y3], [Y4], [Y5A/C], and [30A/B/C]. The
descriptions are, in principle, arranged in the numerical order of assigned data. However, highly relevant signals are
collectively described where one of them first appears. Refer to the function codes or signals in the "Related function
codes/signals (data)" column, if any.
The JAGUAR VXG runs under V/f control, dynamic torque vector control, V/f control with speed sensor, dynamic
torque vector control with speed sensor, vector control without speed sensor, or vector control with speed sensor. Some
function codes apply exclusively to the specific drive control, which is indicated by letters Y (Applicable) and N (Not
applicable) in the "Drive control" column in the tables. (Refer to page 5-2.)
Explanations of each function are given in normal logic system "Active ON."

Any negative logic (Active OFF) command cannot be assigned to the functions marked with "" in the
"Active OFF" column.
„ Inverter running -- RUN (Function code data = 0)
Inverter output on -- RUN2 (Function code data = 35)
These output signals tell the external equipment that the inverter is running at a starting frequency or higher.
If assigned in negative logic (Active OFF), these signals can be used to tell the "Inverter being stopped" state.
Output signal
RUN
RUN2
Basic function
These signals come ON when the inverter is running.
Under V/f control:
These signals come ON if the inverter output frequency
exceeds the starting frequency, and go OFF if it drops
below the stop frequency. The RUN signal can also be
used as a "Speed valid" signal DNZS.
Remarks
Goes OFF even during DC braking or
dew condensation prevention.
Comes ON even during DC braking,
pre-exciting, zero speed control, or
dew condensation prevention.
Under vector control, both RUN and RUN2 come ON when zero speed control or servo-lock function is enabled.
„ Undervoltage detected (Inverter stopped) -- LU (Function code data = 3)
This output signal comes ON when the DC link bus voltage of the inverter drops below the specified undervoltage level,
and it goes OFF when the voltage exceeds the level.
This signal is ON also when the undervoltage protective function is activated so that the motor is in an abnormal stop
state (e.g., tripped).
When this signal is ON, a run command is disabled if given.
„ Torque polarity detected -- B/D (Function code data = 4)
The inverter issues the driving or braking polarity signal to this digital output judging from the internally calculated
torque or torque command. This signal goes OFF when the detected torque is a driving one, and it goes ON when it is a
braking one.
5-79
„ Inverter output limiting -- IOL (Function code data = 5)
Inverter output limiting with delay -- IOL2 (Function code data = 22)
The output signal IOL comes ON when the inverter is limiting the output frequency by activating any of the following
actions (minimum width of the output signal: 100 ms). The output signal IOL2 comes ON when any of the following
output limiting operation continues for 20 ms or more.
• Torque limiting (F40, F41, E16 and E17, Maximum internal value)
• Current limiting by software (F43 and F44)
• Instantaneous overcurrent limiting by hardware (H12 = 1)
• Automatic deceleration (Anti-regenerative control) (H69)
When the IOL signal is ON, it may mean that the output frequency may have deviated from the frequency
specified by the frequency command because of this limiting function.
„ Keypad operation enabled -- KP (Function code data = 8)
This output signal comes ON when the
/
keys are specified as the run command source.
FUNCTION CODES
„ Select AX terminal function -- AX (Function code data = 15)
In response to a run command FWD, this output signal controls the magnetic contactor on the commercial-power
supply side. It comes ON when the inverter receives a run command and it goes OFF after the motor decelerates to stop
with a stop command received.
This signal immediately goes OFF upon receipt of a coast-to-stop command or when an alarm occurs.
Chap. 5
„ Inverter ready to run -- RDY (Function code data = 10)
This output signal comes ON when the inverter becomes ready to run by completing hardware preparation (such as
initial charging of DC link bus capacitors and initialization of the control circuit) and no protective functions are
activated.
„ Universal DO -- U-DO (Function code data = 27)
Assigning this output signal to an inverter's output terminal and connecting the terminal to a digital input terminal of
peripheral equipment via the RS-485 communications link or the fieldbus, allows the inverter to send commands to the
peripheral equipment.
The universal DO can also be used as an output signal independent of the inverter operation.
For the procedure for access to Universal DO via the RS-485 communications link or fieldbus, refer to the
respective instruction manual.
„ Heat sink overheat early warning -- OH (Function code data = 28)㻌
This output signal is used to issue a heat sink overheat early warning that enables you to take a corrective action before
an overheat trip K actually happens.
This signal comes ON when the temperature of the heat sink exceeds the "overheat trip temperature minus 5°C," and it
goes OFF when it drops down to the "overheat trip temperature minus 8°C."
This signal comes ON also when the internal air circulation DC fan (45 kW or above for 200 V class series or 75 kW or
above for 400 V class series) has locked.
„ Lifetime alarm -- LIFE (Function code data = 30)
This output signal comes ON when it is judged that the service life of any one of capacitors (DC link bus capacitors and
electrolytic capacitors on the printed circuit boards) and cooling fan has expired.
This signal should be used as a guide for replacement of the capacitors and cooling fan. If this signal comes ON, use the
specified maintenance procedure to check the service life of these parts and determine whether the parts should be
replaced or not. (Refer to Chapter 7, Section 7.3 "List of Periodic Replacement Parts.")
This signal comes ON also when the internal air circulation DC fan (45 kW or above for 200 V class series or 75 kW or
above for 400 V class series) has locked.

„ Under PID control -- PID-CTL (Function code data = 43)
his output signal comes ON when PID control is enabled ("Cancel PID control" (Hz/PID) = OFF) and a run command
is ON. (Refer to the description of J01.)
When PID control is enabled, the inverter may stop due to the slow flowrate stopping function or other
reasons, with the PID-CTL signal being ON. As long as the PID-CTL signal is ON, PID control is effective,
so the inverter may abruptly resume its operation, depending on the feedback value in PID control.
When PID control is enabled, even if the inverter stops its output during operation because of sensor signals or other
reasons, operation will resume automatically. Design your machinery so that safety is ensured even in such cases.
Otherwise, an accident could occur.

„ In remote operation -- RMT (Function code data = 54)㻌
This output signal comes ON when the inverter switches from local to remote mode.
For details of switching between remote and local modes, refer to Chapter 4, Section 4.2.2 "Remote and local
modes."
„ Terminal [C1] wire break -- C1OFF (Function code data = 59)
This output signal comes ON when the inverter detects that the input current to terminal [C1] drops below 2 mA
interpreting it as the terminal [C1] wire broken.
„ Speed valid -- DNZS (Function code data = 70)
This output signal comes ON when the reference speed or detected one exceeds the stop frequency specified by
function code F25. It goes OFF when the speed is below the stop frequency for 100 ms or longer. Under vector control
with speed sensor, F38 switches the decision criteria between the reference speed and detected one. Under vector
control without speed sensor, the reference speed is used as a decision criteria. ( Refer to the descriptions of F25 and
F38.)
„ Alarm output (for any alarm) -- ALM (Function code data = 99)
This output signal comes ON if any of the protective functions is activated and the inverter enters Alarm mode.
„ Braking transistor broken -- DBAL (Function code data = 105)
If the inverter detects a breakdown of the braking transistor, it issues the braking transistor alarm (GED ) and also the
output signal DBAL. Detection of braking transistor broken can be cancelled by H98.
(200 V class series/ 400 V class series, 22 kW or below) ( Refer to the description of H98.)
Breakdown of the braking transistor could lead to the secondary breakdown of the braking resistor and
inverter’s internal units. Use this output signal DBAL to detect abnormal operation of the built-in braking
transistor and to cut off power to the magnetic contactor in inverter primary circuits, for preventing spread of
the damage.

„ Motor overload early warning signal -- OL
The OL signal is used to detect a symptom of an overload condition (alarm code O) of the motor so that the user can
take an appropriate action before the alarm actually happens.
The OL signal turns ON when the inverter output current exceeds the level specified by E34. In typical cases, set E34
data to 80 to 90% against F11 data (Electronic thermal overload protection for motor 1, Overload detection level).
Specify also the thermal characteristics of the motor with F10 (Select motor characteristics) and F12 (Thermal time
constant).
„ Current detected, Current detected 2 and Current detected 3 -- ID, ID2 and ID3
When the inverter output current exceeds the level specified by E34, E37 or E55 for the period specified by E35, E38 or
E56, the ID, ID2 or ID3 signal turns ON, respectively. When the output current drops below 90% of the rated operation
level, the ID, ID2 or ID3 turns OFF. (The minimum ON-duration is 100 ms.)
„ Low current detected -- IDL
This signal turns ON when the output current drops below the level specified by E37 (Low current detection, Level) for
the period specified by E38 (Timer). When the output current exceeds the "Low current detection level plus 5% of the
inverter rated current," it goes OFF. (The minimum ON-duration is 100 ms.)

PID Display Coefficient A, B
These function codes specify PID display coefficients A and B to convert a PID command (process command or dancer
position command) and its feedback into mnemonic physical quantities to display.
- Data setting range: -999 to 0.00 to 9990 for PID display coefficients A and B
„ Display coefficients for PID process command and its feedback (J01 = 1 or 2)
E40 specifies coefficient A that determines the display value at 100% of the PID process command or its feedback, and
E41 specifies coefficient B that determines the display value at 0%.
The display value is determined as follows:
Display value = (PID process command or its feedback (%))/100 u (Display coefficient A - B) + B
Chap. 5
Example
Maintaining the pressure around 16 kPa (sensor voltage 3.13 V) while the pressure sensor can detect 0 to 30 kPa over
the output voltage range of 1 to 5 V:
Select terminal [12] as a feedback terminal and set the gain to 200% so that 5 V corresponds to 100%.
The following E40 and E41 settings allow you to monitor or specify the values of the PID process command and its
feedback on the keypad as pressure.
FUNCTION CODES
PID display coefficient A (E40) = 30.0, that determines the display value at 100% of PID process command or its
feedback
PID display coefficient B (E41) = -7.5, that determines the display value at 0% of PID process command or its
feedback
To control the pressure at 16 kPa on the keypad, set the value to 16.0.

„ Display coefficients for PID dancer position command and its feedback (J01 = 3)
Under the PID dancer control, the PID command and its feedback operate within the range r100%, so specify the value
at +100% of the PID command or its feedback as coefficient A with E40, and the value at -100% as coefficient B with
E41.
If the sensor output is unipolar, the PID dancer control operates within the range from 0 to +100%, so virtually specify
the value at -100% as coefficient B.
That is, suppose "b" = "Display value at 0%," then:
Display coefficient B = 2b - A
For details about the PID control, refer to the description of J01 and later.
For the display method of the PID command and its feedback, refer to the description of E43.
„ Display coefficient for analog input monitor
By inputting analog signals from various sensors such as temperature sensors in air conditioners to the inverter, you can
monitor the state of peripheral devices via the communications link. By using an appropriate display coefficient, you
can also have various values converted into physical values such as temperature and pressure before they are displayed.
To set up the analog input monitor, use function codes E61 through E63. Use E43 to choose the item to be
displayed.
E42
LED Display Filter
E42 specifies a filter time constant to be applied for displaying the output frequency, output current and other running

When the analog frequency command (setting through terminal [12], [C1], or [V2]) has dropped below 10% of the
reference frequency within 400 ms, the inverter presumes that the analog frequency command wire has been broken and
continues its operation at the frequency determined by the ratio specified by E65 to the reference frequency. Refer
to E20 through E24 and E27 (data = 33).
When the frequency command level (in voltage or current) returns to a level higher than that specified by E65, the
inverter presumes that the broken wire has been fixed and continues to run following the frequency command.

In the diagram above, f1 is the level of the analog frequency command sampled at any given time. The sampling is
repeated at regular intervals to continually monitor the wiring connection of the analog frequency command.
- Data setting range: 0 (Decelerate to stop), 20 to 120%, 999 (Disable)
Avoid an abrupt voltage or current change for the analog frequency command. An abrupt change may be
interpreted as a wire break.
Setting E65 data at "999" (Disable) allows the REF OFF signal ("Reference loss detected") to be issued, but
does not allow the reference frequency to change (the inverter runs at the analog frequency command as
specified).
When E65 = "0" or "999," the reference frequency level at which the broken wire is recognized as fixed is "f1
u 0.2."
When E65 = "100" (%) or higher, the reference frequency level at which the wire is recognized as fixed is "f1 u
1."
The reference loss detection is not affected by the setting of analog input adjustment (filter time constants: C33,
C38, and C43)

(Timer)), respectively. The signal turns OFF when the calculated torque drops below "the level specified by E78 or E80
minus 5% of the motor rated torque." The minimum ON-duration is 100 ms.
„ Low output torque detected--U-TL
This output signal comes ON when the torque value calculated by the inverter or torque command drops below the level
specified by E80 (Low torque detection (Level)) for the period specified by E81 (Low torque detection (Timer)). The

In the inverter’s low frequency operation, as a substantial error in torque calculation occurs, no low torque can be
detected within the operation range at less than 20% of the base frequency (F04). (In this case, the result of recognition
before entering this operation range is retained.)
The U-TL signal goes off when the inverter is stopped.

Chap. 5
Since the motor parameters are used in the calculation of torque, it is recommended that auto-tuning be applied by
function code P04 to achieve higher accuracy.
These function codes enable the inverter to jump over three different points on the output frequency in order to skip
resonance caused by the motor speed and natural frequency of the driven machinery (load).
- While you are increasing the reference frequency, the moment the reference frequency reaches the bottom of the
jump frequency band, the inverter keeps the output at that bottom frequency. When the reference frequency exceeds
the upper limit of the jump frequency band, the internal reference frequency takes on the value of the reference
frequency. When you are decreasing the reference frequency, the situation will be reversed.
- When more than two jump frequency bands overlap, the inverter actually takes the lowest frequency within the
overlapped bands as the bottom frequency and the highest as the upper limit. Refer to the figure on the lower right.

5.2.4 P codes (Motor 1 Parameters)
The JAGUAR VXG drives the motor under V/f control, dynamic torque vector control, V/f control with speed sensor,
dynamic torque vector control with speed sensor, vector control without speed sensor, or vector control with speed
sensor, which can be selected with function codes.
To use the integrated automatic control functions such as auto torque boost, torque calculation monitoring, auto-energy
saving operation, torque limiter, automatic deceleration (anti-regenerative control), auto search for idling motor speed,
slip compensation, torque vector control, droop control, and overload stop, it is necessary to build a motor model in the
inverter by specifying proper motor parameters including the motor capacity and rated current.
If the cabling between the inverter and the motor is long (generally, 20 m or longer) or a reactor is inserted between the
motor and the inverter, however, the apparent motor parameters are different from the actual ones, so auto-tuning or
other adjustments are necessary. For the auto-tuning procedure, refer to Chapter 4 "RUNNING THE MOTOR."
When using a motor made by other manufacturers or a non-standard motor, obtain the datasheet of the motor and
specify the motor parameters manually or perform auto-tuning.
To specify the motor parameters correctly, select the motor type with P99 (Motor 1 Selection), specify the motor rated
capacity with P02, and then initialize the motor parameters with H03. This procedure also applies when the inverter is
switched to the MT/VT mode and a motor with one rank higher capacity is used. When switching the motor between
the 1st to 4th motors, specify the corresponding function codes. (Refer to the description of A42.)
The motor parameters to be specified in P13 through P56 (such as iron loss factors and magnetic saturation factors) are
usually not shown on the motor nameplate or in the test report.
If auto-tuning (P04 = 2 or 3) is not performed , it is not necessary to change the motor parameters from the ones for a
standard motor.

operation on the actual machine.
For motors exclusively designed for vector control, the rated slip of the motor for driving or braking is compensated by
P09 or P11, respectively, to improve output torque accuracy.

Auto Reset (Times and Reset interval)
H04 and H05 specify the auto-reset function that makes the inverter automatically attempt to reset the tripped state and
restart without issuing an alarm output (for any alarm) even if any protective function subject to reset is activated and
the inverter enters the forced-to-stop state (tripped state).
If the protective function is activated in excess of the times specified by H04, the inverter will issue an alarm output (for
any alarm) and not attempt to auto-reset the tripped state.

„ Number of reset times (H04) Data setting range: 0 (Disable), 1 to 10 (times)
H04 specifies the number of reset times for the inverter to automatically attempt to escape the tripped state.
If the "auto-reset" function has been specified, the inverter may automatically restart and run the motor stopped due
to a trip fault, depending on the cause of the tripping.
Design the machinery so that human body and peripheral equipment safety is ensured even when the auto-resetting
succeeds.
Otherwise an accident could occur.

Starting Mode (Auto search)
Starting Mode (Auto search)
H49 (Starting Mode, Auto search delay time 1)
H46 (Starting Mode, Auto search delay time 2)
H09 specifies the starting mode--whether to enable the auto search for idling motor speed to run the idling motor
without stopping it.
The auto search can apply to the restart of the inverter after a momentary power failure and the normal startup of the
inverter individually.
If the terminal command STM ("Enable auto search for idling motor speed at starting") is assigned to a digital input
terminal with any of E01 to E07 (data = 26), the combination of the H09 data and the STM command status switches
the starting modes (whether auto search is enabled or disabled). If no STM is assigned, the inverter interprets STM as
being OFF by default.

Auto search for idling motor speed
Starting the inverter (with a run command ON, BX OFF, auto-reset, etc.) with STM being ON searches for the idling
motor speed for a maximum of 1.2 seconds to run the idling motor without stopping it. After completion of the auto
search, the inverter accelerates the motor up to the reference frequency according to the frequency command and the
preset acceleration time.
Auto search for idling motor speed to follow
5-101
„ Starting Mode (Auto search delay time 1) (H49)
Data setting range: 0.0 to 10.0 (s)
Auto search for the idling motor speed will become unsuccessful if it is done while the motor retains residual voltage. It
is, therefore, necessary to leave the motor for an enough time for residual voltage to disappear. H49 specifies that time
(0.0 to 10.0 sec.).
At the startup triggered by a run command ON, auto search starts with the delay specified by H49. Using H49, therefore,
eliminates the need of the run command timing control when two inverters share a single motor to drive it alternately,
allow the motor to coast to a stop, and restart it under auto search control at each time of inverter switching
„ Starting Mode (Auto search delay time 2) (H46)
Data setting range: 0.1 to 10.0 (s)
At the restart after a momentary power failure, at the start by turning the terminal command BX ("Coast to a stop") OFF
and ON, or at the restart by auto-reset, the inverter applies the delay time specified by H46. The inverter will not start
unless the time specified by H46 has elapsed, even if the starting conditions are satisfied.
Chap. 5
Under auto search control, the inverter searches the motor speed with the voltage applied at the motor start and the
current flowing in the motor, based on the model built with the motor parameters. Therefore, the search is greatly
influenced by the residual voltage in the motor.
At factory shipment, H46 data is preset to a correct value according to the motor capacity for the general purpose motor,
and basically there is no need to modify the data.
Depending on the motor characteristics, however, it may take time for residual voltage to disappear (due to the
secondary thermal time constant of the motor). In such a case, the inverter starts the motor with the residual voltage
remaining, which will cause an error in the speed search and may result in occurrence of an inrush current or an
overvoltage alarm.
If it happens, increase the value of H46 data and remove the influence of residual voltage. (If possible, it is
recommended to set the value around two times as large as the factory default value allowing a margin.)
FUNCTION CODES
• Be sure to auto-tune the inverter preceding the start of auto search for the idling motor speed.
• When the estimated speed exceeds the maximum frequency or the upper limit frequency, the inverter
disables auto search and starts running the motor with the maximum frequency or the upper limit frequency,
whichever is lower.
• During auto search, if an overcurrent or overvoltage trip occurs, the inverter restarts the suspended auto
search.
• Perform auto search at 60 Hz or below.
• Note that auto search may not fully provide the expected/designed performance depending on conditions
including the load, motor parameters, power cable length, and other externally determined events.

„ Torque Control (Speed limits 1 and 2) (d32, d33)
Torque control controls the motor-generating torque, not the speed. The speed is determined secondarily by load torque,
mechanical inertia, and other factors. To prevent a dangerous situation, however, the speed limit functions (d32 and
d33) are provided inside the inverter.
If a regenerative load (which is not generated usually) is generated under droop control, or if function codes
are incorrectly configured, the motor may rotate at an unintended high speed. You can specify the overspeed
level at any value to protect the mechanical system.
• Forward overspeed level = Maximum frequency 1 (F03) x Speed limit 1 (d32) x 120 (%)
• Reverse overspeed level = Maximum frequency 1 (F03) x Speed limit 2 (d33) x 120 (%)
5-103
Running/stopping the motor
Under torque control, the inverter does not control the speed, so it does not perform acceleration or
deceleration by soft-start and stop (acceleration/deceleration time) at the time of startup and stop.
Turning ON a run command starts the inverter to run and outputs the commanded torque. Turning it OFF
stops the inverter so that the motor coasts to a stop.
At the startup in torque control under the "Vector control without speed sensor," the starting operation differs
depending upon whether auto-search is enabled or disabled by d67 as shown below.
Data for d67
0: Disable
1: Enable (At restart after
momentary power failure)
2: Enable (At normal start and
at restart after momentary
power failure)
Operation
At startup, the inverter first starts at zero frequency. Then it accelerates
according to a torque command.
Select this operation for use in which the motor is surely stopped before
startup.
At startup, the inverter searches for idling motor speed and starts
running the motor at the frequency base on the searched speed. Then it
starts torque control.

When the voltage sensed by PTC thermistor exceeds the detection level, motor protective function
(alarm 0h4 ) is triggered, causing the inverter to enter an alarm stop state.
Enable
When the voltage sensed by the PTC thermistor exceeds the detection level, a motor alarm signal is
output but the inverter continues running. You need to assign the "Motor overheat detected by
thermistor" signal (THM) to one of the digital output terminals beforehand, by which a temperature
alarm condition can be detected by the thermistor (PTC) (E20 to E24 and E27, data = 56).
Enable
If the motor overheats and the temperature exceeds the protection level, the inverter issues the
Motor protection alarm 0h4 and stops the motor.
FUNCTION CODES
These function codes specify the PTC (Positive Temperature Coefficient)/NTC (Negative Temperature Coefficient)
thermistor embedded in the motor. The thermistor is used to protect the motor from overheating or output an alarm
signal.
If H26 data is set to "1" or "2" (PTC thermistor), the inverter monitors the voltage sensed by PTC thermistor and protect
the motor even when any of the 2nd to 4th motors is selected. If H26 data is set to "3" (NTC thermistor) and any of the
2nd to 4th motors is selected, the inverter does not perform these functions.
„ Thermistor (for motor) (Level) (H27)
Data setting range: 0.00 to 5.00 (V)
H27 specifies the detection level (expressed in voltage) for the temperature sensed by the PTC thermistor.
The alarm temperature at which the overheat protection becomes activated depends on the characteristics of the PTC
thermistor. The internal resistance of the thermistor will significantly change at the alarm temperature. The detection
level (voltage) is specified based on the change of the internal resistance.

H28
Droop Control
In a system in which two or more motors drive single machinery, any speed gap between inverter-driven motors results
in some load unbalance between motors. The droop control allows each inverter to drive the motor with the speed droop
characteristics for increasing its load, eliminating such kind of load unbalance.
- Data setting range: -60.0 to 0.0 (Hz), (0.0: Disable)
„ Select droop control -- DROOP (E01 to E07, data = 76)
This terminal command DROOP is to switch enabling or disabling the droop control.
DROOP

Droop control

To use droop control, be sure to auto-tune the inverter for the motor beforehand.
The droop control under V/f control applies the acceleration/deceleration time to the frequency obtained as a
result of the droop control to prevent the inverter from tripping even at an abrupt change in load. As a result,
reflecting the frequency compensated by the droop control on the motor speed may be delayed due to the
influence of the acceleration/deceleration time specified, which may look as if the droop control is disabled.
By contrast, the vector control without/with speed sensor contains the current control system and the inverter
does not trip even at an abrupt change in load, so the acceleration/deceleration time does not affect the droop
control. It is, therefore, possible to eliminate load unbalance using the droop control even during
accelerating/decelerating.

„ Cumulative motor run time 1 (H94)
Operating the keypad can display the cumulative run time of motor 1. This feature is useful for management and
maintenance of the mechanical system. H94 allows you to set the cumulative run time of the motor to the desired value,
which enables setting an arbitrary initial data to determine a parts or inverter replacement timing. Specifying "0" clears
the cumulative run time of the motor.
Even when a motor is driven by commercial power, not by the inverter, it is possible to count the cumulative run time
of the motor by detecting the ON/OFF state of the auxiliary contact of the magnetic contactor for switching to the
commercial power line. To enable this function, assign CRUN-M1 (Commercial power driving status of motor 1,
function code data = 72) to one of the digital input terminals.
• H94 data is in hexadecimal notation. It appears, however, in decimal notation on the keypad.
• Cumulative motor run time 2 through 4 can also be counted by assigning CRUN-M2 through CRUN-M4
(Commercial power driving status of motor 2 through 4, function code data = 73 through 75).

In the inverter not equipped with a PWM converter or braking unit, if the regenerative energy returned exceeds the
inverter's braking capability, an overvoltage trip occurs.
To avoid such an overvoltage trip, enable the automatic deceleration (anti-regenerative control) with this function code,
and the inverter controls the output frequency to keep the braking torque around 0 N·m in both the deceleration and
constant speed running phases.

In addition, during deceleration triggered by turning the run command OFF, the anti-regenerative control increases the
output frequency so that the inverter may not stop the load depending on the load state (huge moment of inertia, for
example). To avoid that, H69 provides a choice of cancellation of the anti-regenerative control to apply when three
times the specified deceleration time is elapsed, thus decelerating the motor forcibly.

FUNCTION CODES
„ Torque Limiter (Frequency increment limit for braking) (H76)
Data setting range: 0.0 to 500.0 (Hz)
Since increasing the output frequency too much in the torque limit control mode is dangerous, the inverter has a torque
limiter (Frequency increment limit for braking) that can be specified by H76. The torque limiter limits the inverter's
output frequency to less than "Reference frequency + H76 setting."
Note that the torque limiter activated restrains the anti-regenerative control, resulting in a trip with an overvoltage alarm
in some cases. Increasing the H76 data makes the anti-regenerative control capability high.
• Enabling the automatic deceleration (anti-regenerative control) may automatically increase the deceleration
time.
• When a braking unit is connected, disable the anti-regenerative control. The automatic deceleration control
may be activated at the same time when a braking unit starts operation, which may make the deceleration
time fluctuate.
• If the set deceleration time is too short, the DC link bus voltage of the inverter rises quickly, and
consequently, the automatic deceleration may not follow the voltage rise. In such a case, specify a longer
deceleration time.
H70
Overload Prevention Control
H70 specifies the decelerating rate of the output frequency to prevent a trip from occurring due to an overload. This
control decreases the output frequency of the inverter before the inverter trips due to a heat sink overheat or inverter
overload (with an alarm indication of K or OX, respectively). It is useful for equipment such as pumps where a
decrease in the output frequency leads to a decrease in the load and it is necessary to keep the motor running even when
the output frequency drops.

Light Alarm Selection 1 and 2
If the inverter detects a minor abnormal state "light alarm", it can continue the current operation without tripping while
displaying the "light alarm" indication ODO on the LED monitor. In addition to the indication ODO, the inverter blinks
the KEYPAD CONTROL LED and outputs the "light alarm" signal L-ALM to a digital output terminal to alert the
peripheral equipment to the occurrence of a light alarm. (To use the L-ALM, it is necessary to assign the signal to any
of the digital output terminals by setting any of function codes E20 through E24 and E27 to "98.")

H84, H85
Pre-excitation (Initial level, Time)
A motor generates torque with magnetic flux and torque current. Lag elements of the rising edge of magnetic flux
causes a phenomenon in which enough torque is not generated at the moment of the motor start. To obtain enough
torque even at the moment of motor start, enable the pre-excitation with H84 and H85 so that magnetic flux is
established before a motor start.
„ Pre-excitation (Initial level) (H84)
Data setting range: 100 to 400 (%) (Ratio to the motor's no-load current)
H84 specifies the forcing function for the pre-excitation. It is used to shorten the pre-excitation time. Basically, there is
no need to modify the default setting.
„ Pre-excitation (Time) (H85)
Data setting range: 0.00 (Disable), 0.01 to 30.00 (s)
H85 specifies the pre-excitation time before starting operation. When a run command is inputted, the pre-excitation
starts. After the pre-excitation time specified by H85 has elapsed, the inverter judges magnetic flux to have been
established and starts acceleration. Specify H85 data so that enough time is secured for establishing magnetic flux. The
appropriate value for H85 data depends on the motor capacity. Use the default setting value of H13 data as a guide.

phase loss protection, judgment threshold on the life of DC link bus capacitor, judgment on the life of DC link bus
capacitor, DC fan lock detection, braking transistor error detection, and IP20/IP40 switching, in combination (Bit 0 to
Bit 7).
Automatic lowering of carrier frequency (Bit 0) (Under V/f control only)
This function should be used for important machinery that requires keeping the inverter running.
Even if a heat sink overheat or overload occurs due to excessive load, abnormal surrounding temperature, or cooling
system failure, enabling this function lowers the carrier frequency to avoid tripping (K, K or OXY). Note that
enabling this function results in increased motor noise.
Input phase loss protection (OLQ) (Bit 1)
Upon detection of an excessive stress inflicted on the apparatus connected to the main circuit due to phase loss or
line-to-line voltage unbalance in the three-phase power supplied to the inverter, this feature stops the inverter and
displays an alarm OLQ.
5-115
In configurations where only a light load is driven or a DC reactor is connected, phase loss or line-to-line
voltage unbalance may not be detected because of the relatively small stress on the apparatus connected to the
main circuit.
Output phase loss protection (SO ) (Bit 2)
Upon detection of phase loss in the output while the inverter is running, this feature stops the inverter and displays an
alarm SO.
Where a magnetic contactor is installed in the inverter output circuit, if the magnetic contactor goes OFF
during operation, all the phases will be lost. In such a case, this protection feature does not work.
Judgment threshold on the life of DC link bus capacitor (Bit 3)
FUNCTION CODES
Judgment on the life of DC link bus capacitor (Bit 4)
Whether the DC link bus capacitor has reached its life is determined by measuring the length of time for discharging
after power OFF. The discharging time is determined by the capacitance of the DC link bus capacitor and the load
inside the inverter. Therefore, if the load inside the inverter fluctuates significantly, the discharging time cannot be
accurately measured, and as a result, it may be mistakenly determined that the life has been reached. To avoid such an
error, you can disable the judgment on the life of the DC link bus capacitor. (Even if it is disabled, the judgment based
on the "ON-time counting" while the voltage is applied to the DC link bus capacitor is continued.) For details, refer to
the description of H42.
Since load may vary significantly in the following cases, disable the judgment on the life during operation. Either
conduct the measurement with the judgment enabled under appropriate conditions during periodical maintenance or
conduct the measurement under the operating conditions matching the actual ones.
• Auxiliary input for control power is used.
• An option card or multi-function keypad is used.
• Another inverter or equipment such as a PWM converter is connected to terminals of the DC link bus.
Chap. 5
Bit 3 is used to select the threshold for judging the life of the DC link bus capacitor--the factory default level or
user-setup level.
If the multi-function keypad is mounted, the inverter does not perform automatic capacitance measurement of
the DC link bus capacitor using the factory default level since the inverter's conditions are different from the
ones applied at shipment. It is, therefore, necessary to select the user-setup level. Using the user-setup level
requires performing the setup procedure for the user ordinary operation beforehand.
( Refer to the description of H42.)
DC fan lock detection (Bit 5) (200 V class series: 45 kW or above, 400 V class series: 75 kW or above)
An inverter of 45 kW or above (200 V class series), or of 75 kW or above (400 V class series) is equipped with the
internal air circulation DC fan. When the inverter detects that the DC fan is locked by a failure or other cause, you can
select either continuing the inverter operation or entering into alarm state.
Entering alarm state: The inverter issues the alarm K and coasts to stop the motor.
Continuing operation: The inverter does not enter the alarm mode, and continues operation of the motor.
Note that, however, the inverter turns ON the OH and LIFE signals on the transistor output terminals whenever the DC
fan lock is detected regardless of your selection.
If the ON/OFF control of the cooling fan is enabled (H06 = 1), the cooling fan may stop depending on
operating condition of the inverter. In this case, the DC fan lock detection feature is considered normal (e.g.;
the cooling fan is normally stopped by the stop fan command.) so that the inverter may turn OFF the LIFE or
OH signal output, or enable to cancel the alarm K , even if the internal air circulation DC fan is locked due
to a failure etc. (When you start the inverter in this state, it automatically issues the run fan command, then the
inverter detects the DC fan lock state, and turn ON the LIFE or OH output or enters the alarm K state.)
F codes
E codes
C codes
Note that, operating the inverter under the condition that the DC fan is locked for long time may shorten the life of
electrolytic capacitors on the PCBs due to local high temperature inside the inverter. Be sure to check with the LIFE

The JAGUAR VXG can switch control parameters even when it is running so that a single inverter can drive four
motors by switching them or turn the energy saving operation ON or OFF for the setup change (e.g., gear switching)
that causes the moment of inertia of the machinery to change.

The combination of digital input terminal commands M2, M3 and M4 (Select motor 2, 3 and 4) switches between the
1st, 2nd, 3rd and 4th motors as listed below. (Function codes E01 through E07, data = 12, 36, or 37) When the motor is
switched, the function code group with which the inverter drives the motor is also switched to the corresponding one.
At the same time, the inverter outputs the corresponding signal from the "Motor 1 selected" signal SWM1 through the
"Motor 4 selected" signal SWM4 (Function codes E20 through E27 data = 48, 49, 50, or 51) in order to switch the
external switch to that selected motor.

Parameter switching is possible even during operation. For example, speed control P (Gain) and I (Integral time) listed
in Table 5.5 can be switched.
Switching these parameters during operation may cause an abrupt change of torque and result in a mechanical shock,
depending on the driving condition of the load.
To reduce such a mechanical shock, the inverter decreases the abrupt torque change using the ramp function of ASR
Switching Time (d25).

PID Control (Mode selection)
Under PID control, the inverter detects the state of a control target object with a sensor or the similar device and
compares it with the commanded value (e.g., temperature control command). If there is any deviation between them, the
PID control operates so as to minimize it. That is, it is a closed loop feedback system that matches controlled variable
(feedback amount). The PID control expands the application area of the inverter to the process control (e.g., flow
control, pressure control, and temperature control) and the speed control (e.g., dancer control).
If PID control is enabled (J01 = 1, 2 or 3), the frequency control of the inverter is switched from the drive frequency
command generator block to the PID command generator block.

Application example: Process control (for air conditioners, fans and pumps)
The operating range for PID process control is internally controlled as 0% through 100%. For the given feedback input,
determine the operating range to be controlled by means of gain adjustment.
Example: When the output level of the external sensor is within the range of 1 to 5 V:
• Use terminal [12] since the connection terminal is for voltage input.
• Set the gain (C32 for analog input adjustment) at 200% in order to make the maximum value (5 V) of the external
sensor's output correspond to 100%. Note that the input specification for terminal [12] is 0 to 10 V corresponding to 0
to 100%; thus, a gain factor of 200% (= 10 V y 5 V u 100) should be specified. Note also that any bias setting does
not apply to feedback control.
Application examples: Dancer control (for winders)
Example 1. When the output level of the external sensor is r7 VDC:
• Use terminal [12] since the voltage input is of bipolar.
• When the external sensor's output is of bipolar, the inverter controls the speed within the range of r100%. To convert
the output r7 VDC to r100%, set the gain (C32 for analog input adjustment) at 143% as calculated below.
10 V
| 143%
7V
Example 2. When the output level of the external sensor is 0 to 10 VDC:
• Use terminal [12] since the connection terminal is for voltage input.
• When the external sensor's output is of unipolar, the inverter controls the speed within the range of 0 to 100%.
In this example, it is recommended that the dancer reference position be set around the +5 V (50%) point.
PID Display Coefficient and Monitoring
To monitor the PID command and its feedback value, set the display coefficient to convert the values into
easy-to-understand mnemonic physical quantities, such as temperature.
Refer to function codes E40 and E41 for details on display coefficients, and to E43 for details on monitoring.

PID Control (P (Gain), I (Integral time), D (Differential time), Feedback filter)
„ P gain (J03)
Data setting range: 0.000 to 30.000 (times)
J03 specifies the gain for the PID processor.
P (Proportional) action
An operation in which the MV (manipulated value: output frequency) is proportional to the deviation is called P action,
which outputs the MV in proportion to deviation. However, the MV alone cannot eliminate deviation.
Gain is data that determines the system response level against the deviation in P action. An increase in gain speeds up
response, but an excessive gain may oscillate the inverter output. A decrease in gain delays response, but it stabilizes
the inverter output.
Chap. 5
I (Integral) action
FUNCTION CODES
„ I integral time (J04)
Data setting range: 0.0 to 3600.0 (s), 0.0 means that the integral component is ineffective.
J04 specifies the integral time for the PID processor.
An operation in which the change rate of the MV (manipulated value: output frequency) is proportional to the integral
value of deviation is called I action, which outputs the MV that integrates the deviation. Therefore, I action is effective
in bringing the feedback amount close to the commanded value. For the system whose deviation rapidly changes,
however, this action cannot make it react quickly.
The effectiveness of I action is expressed by integral time as parameter, that is J04 data. The longer the integral time,
the slower the response. The reaction to the external disturbance also becomes slow. The shorter the integral time, the
faster the response. Setting too short integral time, however, makes the inverter output tend to oscillate against the
external disturbance.
F codes
„ D differential time (J05)
Data setting range: 0.00 to 600.00 (s), 0.00 means that the differential component is ineffective.
J05 specifies the differential time for the PID processor.
D (Differential) action
E codes
C codes
P codes
H codes
An operation in which the MV (manipulated value: output frequency) is proportional to the differential value of the
deviation is called D action, which outputs the MV that differentiates the deviation. D action makes the inverter quickly
react to a rapid change of deviation.
The effectiveness of D action is expressed by differential time as parameter, that is J05 data. Setting a long differential
time will quickly suppress oscillation caused by P action when a deviation occurs. Too long differential time makes the
inverter output oscillation more. Setting short differential time will weakens the suppression effect when the deviation
occurs.

The combined uses of P, I, and D actions are described below.
(1) PI control
PI control, which is a combination of P and I actions, is generally used to minimize the remaining deviation caused by P
action. PI control always acts to minimize the deviation even if a commanded value changes or external disturbance
steadily occurs. However, the longer the integral time, the slower the system response to quick-changed control.
P action can be used alone for loads with very large part of integral components.
(2) PD control
In PD control, the moment that a deviation occurs, the control rapidly generates greater MV (manipulated value) than
that generated by D action alone, to suppress the deviation increase. When the deviation becomes small, the behavior of
P action becomes small.
A load including the integral component in the controlled system may oscillate due to the action of the integral
component if P action alone is applied. In such a case, use PD control to reduce the oscillation caused by P action, for
keeping the system stable. That is, PD control is applied to a system that does not contain any damping actions in its
process.
(3) PID control
PID control is implemented by combining P action with the deviation suppression of I action and the oscillation
suppression of D action. PID control features minimal control deviation, high precision and high stability.
In particular, PID control is effective to a system that has a long response time to the occurrence of deviation.
Follow the procedure below to set data to PID control function codes.
It is highly recommended that you adjust the PID control value while monitoring the system response waveform with an
oscilloscope or equivalent. Repeat the following procedure to determine the optimal solution for each system.
- Increase the data of J03 (PID control P (Gain)) within the range where the feedback signal does not oscillate.
- Decrease the data of J04 (PID control I (Integral time)) within the range where the feedback signal does not oscillate.
- Increase the data of J05 (PID control D (Differential time)) within the range where the feedback signal does not
oscillate.
Refining the system response waveforms is shown below.
1) Suppressing overshoot
Increase the data of J04 (Integral time) and decrease that of J05 (Differential time.)
2) Quick stabilizing (moderate overshoot allowable)
Decrease the data of J03 (Gain) and increase that of J05 (Differential time).
3) Suppressing oscillation whose period is longer than the integral time specified by J04
Increase the data of J04 (Integral time).
4) Suppressing oscillation whose period is approximately the same as the time specified by J05 (Differential time)
Decrease the data of J05 (Differential time).
Decrease the data of J03 (Gain), if the oscillation cannot be suppressed even though the differential time is set at 0
sec.
5-125
„ Feedback filter (J06)
Data setting range: 0.0 to 900.0 (s)
J06 specifies the time constant of the filter for feedback signals under PID control. (This setting is used to stabilize the
PID control loop. Setting too long a time constant makes the system response slow.)
To specify the filter for feedback signals finely under PID dancer control, apply filter time constants for analog
input (C33, C38 and C43).

J16 specifies the period from when the PID output drops below the frequency specified by J15 until the inverter starts
deceleration to stop.
„ PID control (Starting frequency) (J17)
Data setting range: 0.0 to 500.0 (Hz)
J17 specifies the starting frequency. Set J17 to a frequency higher than the stop frequency for slow flowrate (J15). If the
specified starting frequency is lower than the stop frequency for slow flowrate, the latter stop frequency is ignored; the
slow flowrate stopping function is triggered when the output of the PID processor drops below the specified starting
frequency.
FUNCTION CODES
„ PID control (Stop frequency for slow flowrate) (J15) Data setting range: 0.0 (Disable), 1.0 to 500.0 (Hz)
J15 specifies the frequency which triggers slow flowrate stop of inverter.
Chap. 5
Slow flowrate stopping function (J15 to J17)
J15 to J17 configure the slow flowrate stopping function in pump control, a function that stops the inverter when the
discharge pressure rises, causing the volume of water to decrease.
When the discharge pressure has increased, decreasing the reference frequency (output of the PID processor) below the
stop frequency for slow flowrate level (J15) for the period of slow flowrate level stop latency (J16), the inverter
decelerates to stop, while PID control itself continues to operate. When the discharge pressure decreases, increasing the
reference frequency (output of the PID processor) above the starting frequency (J17), the inverter resumes operation.
„ Assignment of PID-STP ("Motor stopped due to slow flowrate under PID control")
(E20 to E24 and E27, data = 44)
Assigning the digital output signal PID-STP to any of the programmable, output terminals with any of E20 through E24
and E27 (data = 44) enables the signal to output when the inverter stops due to the slow flowrate stopping function
under PID control.

Pressurization before slow flowrate stopping (J08 and J09)
Specifying J08 (Pressurization starting frequency) and J09 (Pressurizing time) enables pressurization control when the
frequency drops below the level specified by J15 (Stop frequency for slow flowrate) for the period specified by J16.
During the pressurization, the PID control is in the hold state.
This function prolongs the stopping time of equipment with a bladder tank by pressurizing immediately before the
frequency drops below the level at which the inverter stops the motor, thus enabling energy saving operation.
Because the pressurization starting frequency (J08) can be specified with a parameter, pressurization setting suitable for
the equipment is possible.

„ Brake signal -- BRKS (E20 to E24 and E27, data = 57)
This signal outputs a brake control command that releases or activates the brake.
Releasing the Brake
When any of the inverter output current, output frequency, or torque command value exceeds the specified level of the
brake signal (J68/J69/J95) for the period specified by J70 (Brake signal (Brake-OFF timer)), the inverter judges that
required motor torque is generated and turns the signal BRKS ON for releasing the brake.
This prevents a hoisted load from falling down due to an insufficient torque when the brake is released.

Servo-lock (Gain, Completion timer, Completion width)
Servo-lock
This function servo-locks the inverter to hold the motor within the positioning completion range specified by J99 for the
period specified by J98 even if an external force applies to the load.
When the inverter is servo-locked, it keeps the output frequency low; therefore, use the inverter under the
following specified thermal restriction: Output current within the range of 150% of the rated current for 3
seconds and 80% for continuous operation. (Note that under the restriction, the inverter automatically limits
the carrier frequency under 5 kHz.)

Notes for using servo-lock

If a positioning error exceeds the value equivalent to four rotations of the motor shaft when the inverter is
servo-locked, the inverter issues a positioning control error signal HUR.
H codes
(2) Stop frequency (F25) under servo-lock
Since servo-lock starts when the output frequency is below the stop frequency (F25), it is necessary to specify such
F25 data that does not trigger HUR (that is, specify the value equivalent to less than 4 rotations of the motor shaft).

These function codes control the speed control sequence for normal operations. For application of each function code,
refer to the figure below and the subsequent descriptions.
Block diagram of the speed control sequence
„ Speed command filter (d01)
Data setting range: 0.000 to 5.000 (s)
d01 specifies a time constant determining the first order delay of the speed command filter.
Modify this data when an excessive overshoot occurs against the speed command change.
Increasing the filter time constant stabilizes the speed command and reduces overshoot against the speed command
change, but it slows the response speed of the inverter.
„ Speed detection filter (d02)
Data setting range: 0.000 to 0.100 (s)
Modify this data when the control target (machinery) is oscillatory due to deflection of a drive belt or other causes so
that ripples (oscillatory components) are superimposed on the detected speed, causing hunting (undesirable oscillation
of the system) and blocking the PI processor gain from increasing (resulting in a slow response speed of the inverter). In
addition, if the lower encoder (PG) resolution makes the system oscillatory, try to modify this data.
Increasing the time constant stabilizes the detected speed and raises the PI processor gain even with ripples
superimposed on the detected speed. However, the detected speed itself delays, resulting in a slower speed response,
larger overshoot, or hunting.
„ P gain (d03)
Data setting range: 0.1 to 200.0 (times)
Data setting range: 0.001 to 9.999 (s)
I integral time (d04)
d03 and d04 specify the gain and integral time of the speed regulator (PI processor), respectively.
P gain
Definition of "P gain = 1.0" is that the torque command is 100% (100% torque output of each inverter capacity) when
the speed deviation (reference speed – actual speed) is 100% (equivalent to the maximum speed).
Determine the P gain according to moment of inertia of machinery loaded to the motor output shaft. Larger moment of
inertia needs larger P gain to keep the flat response in whole operations.
Specifying a larger P gain improves the quickness of control response, but may cause a motor speed overshooting or
hunting (undesirable oscillation of the system). Moreover, mechanical resonance or vibration sound on the machine or
motor could occur due to excessively amplified noises. If it happens, decreasing P gain will reduce the amplitude of the
resonance/vibration. A too small P gain results in a slow inverter response and a speed fluctuation in low frequency,
which may prolong the time required for stabilizing the motor speed.
Integral time
Specifying a shorter integral time shortens the time needed to compensate the speed deviation, resulting in quick
response in speed. Specify a short integral time if quick arrival to the target speed is necessary and a slight overshooting
in the control is allowed; specify a long time if any overshooting is not allowed and taking longer time is allowed.
If a mechanical resonance occurs and the motor or gears sound abnormally, setting a longer integral time can transfer
the resonance point to the low frequency zone and suppress the resonance in the high frequency zone.
„ Output Filter (d06)
Data setting range: 0.000 to 0.100 (s)
d06 specifies the time constant for the first order delay of the speed controller output filter.
Use this function code when setting of the P gain and/or integral time cannot control mechanical resonance such as
hunting or vibration. Generally, setting a larger value to this time constant decreases the amplitude of resonance;
however, a too long time constant may make the system unstable.

A49, b49, r49 (Speed control 2 to 4, Notch filter resonance frequency)
A50, b50, r50 (Speed control 2 to 4, Notch filter attenuation level)
These function codes specify speed control using notch filters. The notch filters make it possible to decrease the speed
loop gain only in the vicinity of the predetermined resonance points, suppressing the mechanical resonance.
The notch filters are available only under "vector control with speed sensor."
Setting the speed loop gain at a high level in order to obtain quicker speed response may cause mechanical resonance. If
it happens, decreasing the speed loop gain is required to slow the speed response as a whole. In such a case, using the
notch filters makes it possible to decrease the speed loop gain only in the vicinity of the predetermined resonance points
and set the speed loop gain at a high level in other resonance points, enabling a quicker speed response as a whole.

(Detection timer) (d22)
Data setting range: 0.00 to 10.00 (s)
If the speed regulator's deviation (between the reference speed and detected one) is within the specified range (d21), the
signal DSAG turns ON. If the deviation is out of the specified range (d21) for the period specified by d22, the signal
turns OFF. This signal allows the user to check whether the speed regulator works properly or not.
If the deviation (between the reference speed and detected one) is out of the specified range (d21) for the period
specified by d22, the inverter judges it as a PG error.
Data setting for d23, however, defines the detection conditions and the error processing after the error detection.

When the inverter cannot follow the speed
command (even after the soft-starting) due to a
heavy overload or the like, and the detected speed
is slow against the reference speed, the inverter
does not interpret this situation as a PG error.
The inverter interprets the situation above as a PG
error.
The inverter outputs the PG error
detected signal PG-ERR and continues to
run.
The inverter enters the coast-to-stop state
outputting the HUH alarm, and also outputs
the PG error detected signal PG-ERR.

Enabling an operation limiting function such as the torque limit and droop control will increase the deviation
caused by a huge gap between the reference speed and actual one. In this case, the inverter may trip
interpreting this situation as a PG error, depending on the running status. To avoid this incident, set the d23
data to "0: Continue to run" to prevent the inverter from tripping even if any of those limiting functions is
activated.

Torque Control (Speed limit 1 and Speed limit 2)
d41
Application-Defined Control
(Refer to H18.)
The constant peripheral speed control is available as an application, which suppresses an increase in peripheral speed
(line speed) resulting from the increasing radius of the take-up roll in a winder system.
In a winder system (e.g., roving frames, wiredrawing machines), if the inverter continues to run the motor at a constant
speed, the take-up roll gets bigger with materials (roving, wire, etc.) and its radius increases so that the winding speed
of the take-up roll increases.
Under the application-defined control, to keep the peripheral speed (winding speed) constant, the inverter detects the
winding speed using an encoder and controls the motor rotation according to the encoder feedback.
„ Application-Defined Control (d41)
d41 specifies whether to enable or disable the constant peripheral speed control.

Like usual speed controls, it is necessary to adjust the speed command filter, speed detection filter, P gain, and integral
time in the speed control sequence that controls the peripheral speed at a constant level.
Function code
Name
Key points
d01
Speed control
(Speed command filter)
If an excessive overshoot occurs for a speed command change,
increase the filter constant.
d02
Speed control
(Speed detection filter)
If ripples are superimposed on the speed detection signal so that the
speed control gain cannot be increased, increase the filter constant to
obtain a larger gain.
d03
Speed control P
(Gain)
If hunting is caused in the motor speed control, decrease the gain.
If the motor response is slow, increase the gain.
d04
Speed control I
(Integral time)
If the motor response is slow, decrease the integral time.

„ Cancel constant peripheral speed control Hz/LSC (Function code E01 to E07, data = 70)
Turning ON Hz/LSC cancels the constant peripheral speed control. This disables the frequency compensation of PI
operation, resulting in no compensation for a take-up roll getting bigger and an increase in the winding speed.
Use this signal to temporarily interrupt the control for repairing a thread break, for example.

„ Hold the constant peripheral speed control frequency in the memory LSC-HLD
(Function code E01 to E07, data = 71)
If this signal is ON under constant peripheral speed control, stopping the inverter (including an occurrence of an alarm
and a coast-to-stop command) or turning OFF Hz/LSC saves the current frequency command compensating for a
take-up roll getting bigger, in the memory. At the time of restart, the saved frequency command applies and the inverter
keeps the peripheral speed constant.

Enable (Saving the frequency command compensating for a take-up roll getting bigger)
Shutting down the inverter power during an operation stop loses the frequency compensation data saved in the

large overshoot may occur.

Speed Control Limiter
d70 specifies a limiter for the PI value output calculated in speed control sequence under V/f control with speed sensor
or dynamic torque vector control with speed sensor.
A PI value output is within the "slip frequency u maximum torque (%)" in a normally controlled state.
If an abnormal state such as a temporary overload arises, the PI value output greatly fluctuates and it may take a long
time for the PI value output to return to the normal level. To suppress such abnormal operation, the PI value output can
be limited with d70.

„ Notes for using a customizable logic
A customizable logic performs processing every 2 ms in the following sequence.
(1) At the start of processing, the customizable logic latches all of the external input signals entered to steps 1 to 10 to
ensure simultaneity.
(2) Logical operations are performed in the order of steps 1 to 10.
(3) If an output of a particular step applies to an input at the next step, the output of the step having processing priority
can be used in the same processing.
(4) The customizable logic updates all of the five output signals at the same time.
Chap. 5
When configuring a logic circuit, take into account the processing order of the customizable logic. Otherwise, a delay in
processing of logical operation leads to a signal delay problem, resulting in no expected output, slow processing, or a
hazard signal issued.
An accident or injuries could occur.
„ Customizable logic timer monitor (Step selection) (U91)
FUNCTION CODES
Ensure safety before modifying customizable logic related function code settings (U codes and related function
codes) or turning ON the "Cancel customizable logic" terminal command CLC. Depending upon the settings, such
modification or cancellation of the customizable logic may change the operation sequence to cause a sudden motor
start or an unexpected motor operation.

RS-485 communications errors include logical errors (such as address error, parity error, framing error), transmission
protocol error, and physical errors (such as no-response error specified by y08 and y18). The inverter can recognize
such an error only when it is configured with a run or frequency command sourced through the RS-485 communications
link and it is running. If none of run and frequency commands is sourced through the RS-485 communications link or
the inverter is not running, the inverter does not recognize any error occurrence.

Communication Data Storage Selection
A nonvolatile storage in the inverter has a limited number of rewritable times (100,000 to 1,000,000 times). Saving data
into the storage so many times unnecessarily will no longer allow the storage to save data, causing memory errors.
For frequent data writing via the communications link, therefore, a temporary storage is provided instead of the
nonvolatile storage. To use the temporary storage, set the y97 data at "1." Using the temporary storage reduces the
number of data writing times into the nonvolatile storage, preventing memory errors.
Setting the y97 data at "2" saves all data written in the temporary storage into the nonvolatile one.
Changing the y97 data requires simultaneous keying of

Loader Link Function (Mode selection)
(Refer to H30.)
This is a link switching function for JAGUAR Loader. Rewriting the data of y99 to enable RS-485 communications
from Loader helps Loader send the inverter the frequency and/or run commands. Since the data to be set in the function
code of the inverter is automatically set by Loader, no keypad operation is required.
While Loader is selected as the source of the run command, if the computer runs out of control and cannot be stopped
by a stop command sent from Loader, disconnect the RS-485 communications cable from the port 1 or the USB cable,
connect a keypad instead, and reset the y99 data to "0." This setting "0" in y99 means that the run and frequency
command source specified by function code H30 takes place instead of JAGUAR Loader.
Note that the inverter cannot save the setting of y99. When power is turned off, the data in y99 is lost (y99 is reset to
"0").

Chapter 6 TROUBLESHOOTING
6.1 Protective Functions
The JAGUAR VXG series of inverters has various protective functions as listed below to prevent the system from going down
and reduce system downtime. The protective functions marked with an asterisk (*) in the table are disabled by default. Enable
them according to your needs.
The protective functions include, for example, the "heavy alarm" detection function which, upon detection of an abnormal state,
displays the alarm code on the LED monitor and causes the inverter to trip, the "light alarm" detection function which displays
the alarm code but lets the inverter continue the current operation, and other warning signal output functions.
If any problem arises, understand the protective functions listed below and follow the procedures given in Sections 6.2 and
onwards for troubleshooting.
Related
function code
"Heavy alarm" detection
This function detects an abnormal state, displays the corresponding alarm code,
and causes the inverter to trip. The "heavy alarm" codes are check-marked in the
"Heavy alarm" object column in Table 6.1. For details of each alarm code, see the
corresponding item in the troubleshooting.
The inverter retains the last four alarm codes and their factors together with their
running information applied when the alarm occurred, so it can display them.
H98
"Light alarm" detection*
This function detects an abnormal state categorized as a "light alarm," displays
ODO and lets the inverter continue the current operation without tripping.
It is possible to define which abnormal states should be categorized as a "light
alarm" using function codes H81 and H82. The "light alarm" codes are
check-marked in the "Light alarm" object column in Table 6.1.
For how to check and release light alarms, see Section 6.5 "If the "Light Alarm"
Indication (ODO) Appears on the LED Monitor."
H81
H82
Stall prevention
When the output current exceeds the current limiter level (F44) during
acceleration/ deceleration or constant speed running, this function decreases the
output frequency to avoid an overcurrent trip.
F44
Overload prevention
control*
Before the inverter trips due to a heat sink overheat (K) or inverter overload
(OX ), this function decreases the output frequency to reduce the load.
H70
Automatic deceleration*
(Anti-regenerative
control)
If regenerative energy returned exceeds the inverter's braking capability, this
function automatically increases the deceleration time or controls the output
frequency to avoid an overvoltage trip.
H69
Deceleration
characteristics*
(Excessive regenerative
energy proof braking
capability)
During deceleration, this function increases the motor energy loss and decreases
the regenerative energy returned to avoid an overvoltage trip (X ).
Chap. 6
Description
Protective function
This function detects a reference frequency loss (due to a broken wire, etc.),
Reference loss detection* continues the inverter operation at the specified frequency, and issues the
"Command loss detected" signal REF OFF.
E65
Automatic lowering of
carrier frequency
Before the inverter trips due to an abnormal surrounding temperature or output
current, this function automatically lowers the carrier frequency to avoid a trip.
H98
Dew condensation
prevention*
Even when the inverter is in stopped state, this function feeds DC current across
the motor at certain intervals to raise the motor temperature for preventing dew
condensation.
J21
Motor overload early
warning*
When the inverter output current has exceeded the specified level, this function
issues the "Motor overload early warning" signal OL before the thermal overload
protection function causes the inverter to trip for motor protection. This function
exclusively applies to the 1st motor.
E34
E35
Auto-reset*
When the inverter has stopped because of a trip, this function allows the inverter
to automatically reset and restart itself. (The number of retries and the latency
between stop and reset can be specified.)
H04
H05
Forced stop*
Upon receipt of the "Force to stop" terminal command STOP, this function
interrupts the run and other commands currently applied in order to forcedly
decelerate the inverter to a stop.
H56
Surge protection
This function protects the inverter from a surge voltage invaded between main
circuit power lines and the ground.

6.2 Before Proceeding with Troubleshooting
If any of the protective functions has been activated, first remove the cause. Then, after checking that the all run commands
are set to OFF, release the alarm. If the alarm is released while any run commands are set to ON, the inverter may supply the
power to the motor, running the motor.
Injury may occur.
- Even if the inverter has interrupted power to the motor, if the voltage is applied to the main circuit input terminals L1/R,
L2/S and L3/T, voltage may be output to inverter output terminals U, V, and W.
- Turn OFF the power and wait at least five minutes for inverters with a capacity of 22 kW or below, or at least ten
minutes for inverters with a capacity of 30 kW or above. Make sure that the LED monitor and charging lamp are
turned OFF. Further, make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the
terminals P (+) and N (-) has dropped to the safe level (+25 VDC or below).
Electric shock may occur.
Follow the procedure below to solve problems.

[ 9 ] K Inverter internal overheat
[ 11 ] GEK Braking resistor overheated
Problem
The electronic thermal protection for the braking resistor has been activated.
Possible Causes
What to Check and Suggested Measures
(1) Braking load is too heavy.
Reconsider the relationship between the braking load estimated and the real load.
Î Lower the real braking load.
Î Review the selection of the braking resistor and increase the braking capability
(Modification of related function code data (F50, F51, and F52) is also
required.)
(2) Specified deceleration time is
too short.
Recalculate the deceleration torque and time needed for the load currently applied,
based on a moment of inertia for the load and the deceleration time.
Î Increase the deceleration time (F08, E11, E13, E15, and H56).
Î Review the selection of the braking resistor and increase the braking capability.
(Modification of related function code data (F50, F51, and F52) is also
required.)
(3) Incorrect setting of function
code data F50, F51, and F52.
Recheck the specifications of the braking resistor.
Î Review data of function codes F50, F51, and F52, then modify them.
Note: The inverter issues an overheat alarm of the braking resistor by monitoring the magnitude of the braking load, not by
measuring its surface temperature.
When the braking resistor is frequently used so as to exceed the settings made by function codes F50, F51, and F52, therefore,
the inverter issues an overheat alarm even if the surface temperature of the braking resistor does not rise. To squeeze out full
performance of the braking resistor, configure function codes F50, F51, and F52 while actually measuring the surface
temperature of the braking resistor.
[ 12 ] IXV Fuse blown
Problem
The fuse inside the inverter blew.
Possible Causes
What to Check and Suggested Measures
(1) The fuse blew due to
short-circuiting inside the
inverter.
Check whether there has been any excess surge or noise coming from outside.
Î Take measures against surges and noise.
Î Have the inverter repaired.
[ 13 ] SEI Charger circuit fault
Problem
The magnetic contactor for short-circuiting the charging resistor failed to work.
Possible Causes
What to Check and Suggested Measures
(1) The control power was not
supplied to the magnetic
contactor intended for
short-circuiting the charging
resistor.
Check that, in normal connection of the main circuit (not a connection via the DC
link bus), the connector (CN R) on the power printed circuit board (power PCB) is
not inserted to NC .
Î Insert the connector (CN R) to FAN .
Check whether you quickly turned the circuit breaker ON and OFF to confirm safety
after cabling/wiring.
Î Wait until the DC link bus voltage has dropped to a sufficiently low level and
then release the current alarm. After that, turn ON the power again. (Do not turn
the circuit breaker ON and OFF quickly.)
(Turning ON the circuit breaker supplies power to the control circuit to the
operation level (lighting the LEDs on the keypad) in a short period. Immediately
turning it OFF even retains the control circuit power for a time, while it shuts
down the power to the magnetic contactor intended for short-circuiting the
charging resistor since the contactor is directly powered from the main power.
Under such conditions, the control circuit can issue a turn-on command to the
magnetic contactor, but the contactor not powered can produce nothing. This
state is regarded as abnormal, causing an alarm.)

7.3 List of Periodic Replacement Parts
Each part of the inverter has its own service life that will vary according to the environmental and operating conditions. It is
recommended that the following parts be replaced at the specified intervals.
When the replacement is necessary, consult your IMO representative.
Table 7.2 Replacement Parts
Part name
DC link bus capacitor
Standard replacement intervals (See Note below.)
10 years
Electrolytic capacitors on printed circuit boards
10 years
Cooling fans
10 years
Fuse
10 years (90 kW or above)
(Note) These replacement intervals are based on the inverter's service life estimated at a surrounding temperature of 40qC at
100% (CT-mode inverters) or 80% (MT/VT-mode inverters) of full load. In environments with a surrounding
temperature above 40qC or a large amount of dust or dirt, the replacement intervals may be shorter.
Standard replacement intervals mentioned above are only a guide for replacement, not a guaranteed service life.
7-2
7.3.1 Judgment on service life
The inverter has the life prediction function for some parts which measures the discharging time or counts the voltage applied
time, etc. The function allows you to monitor the current lifetime state on the LED monitor and judge whether those parts are
approaching the end of their service life.
The life prediction function can also issue early warning signals if the life time alarm command LIFE is assigned to any of the
digital output terminals. (Refer to "[ 3 ] Early warning of lifetime alarm" later in this section.)
Table 7.3 lists the parts whose service life can be predicted and details the life prediction function. The predicted values should
be used only as a guide since the actual service life is influenced by the surrounding temperature and other usage environments.

„ Notes for the judgment on the service life of the DC link bus capacitor
The service life of the DC link bus capacitor can be judged by the "measurement of discharging time" (c to f) or "ON-time
counting" (g).
c The discharging time of the DC link bus capacitor depends largely on the inverter's internal load conditions, e.g. options
attached or ON/OFF of digital I/O signals. If actual load conditions are so different from the ones at which the
initial/reference capacitance is measured that the measurement result falls out of the accuracy level required, then the
inverter does not perform measuring.
The
capacitance measuring conditions at shipment are extremely restricted--e.g., with the remote keypad mounted and all
d
input terminals being OFF--in order to stabilize the load and measure the capacitance accurately. Those conditions are,
therefore, different from the actual operating conditions in almost all cases. If the actual operating conditions are the same
as those at shipment, shutting down the inverter power automatically measures the discharging time; however, if they are
different, no automatic measurement is performed. To perform it, put those conditions back to the factory default ones and
shut down the inverter. For the measuring procedure, see [ 1 ] given on the next page.
e To measure the capacitance of the DC link bus capacitor under ordinary operating conditions when the power is turned
OFF, it is necessary to set up the load conditions for ordinary operation and measure the reference capacitance (initial
setting) when the inverter is introduced. For the reference capacitance setup procedure, see [ 2 ] given on page 7-5.
Performing the setup procedure automatically detects and saves the measuring conditions of the DC link bus capacitor.
Setting bit 3 of H98 data to 0 restores the inverter to the measurement in comparison with the initial capacitance measured
at shipment.
f If the multi-function keypad is mounted, the inverter does not measure the discharging time automatically since the
inverter's conditions are different from the ones applied at shipment. It is, therefore, necessary to perform the setup
procedure mentioned in e above to enable the measurement under ordinary operating conditions.
To make an accurate judgment on the service life of the DC ink bus capacitor (accurate measurement of the capacitance),
select the judgment procedure according to the keypad type and the measuring conditions, following the flowchart given on
the next page.

g In a machine system where the inverter main power is rarely shut down, the inverter does not measure the discharging time.
For such an inverter, the ON-time counting is provided. The ON-time counting result can be represented as "elapsed
time"(B ) and "time remaining before the end of life" (B ) as shown in Table 7.3, "On the LED monitor."
When the inverter uses an auxiliary control power input, the load conditions widely differ so that the discharging time
cannot be accurately measured. To prevent unintended measuring, the discharging time measurement can be disabled
with the function code H98 (Bit 4 = 0).
[ 1 ] Measuring the capacitance of DC link bus capacitor in comparison with initial one at shipment
When bit 3 of H98 data is 0, the measuring procedure given below measures the capacitance of DC link bus capacitor in
comparison with initial one at shipment when the power is turned OFF. The measuring result can be displayed on the keypad as
a ratio (%) to the initial capacitance.
-------------------------------------------------- Capacitance measuring procedure ------------------------------------------------------1) To ensure validity in the comparative measurement, put the condition of the inverter back to the state at factory shipment.
x Remove the option card (if already in use) from the inverter.
x In case another inverter is connected via the DC link bus to the P(+) and N(-) terminals of the main circuit, disconnect the
wires. (You do not need to disconnect a DC reactor (optional), if any.)
x Disconnect power wires for the auxiliary input to the control circuit (R0, T0).
x Mount the remote keypad on the inverter.
x Turn OFF all the digital input signals fed to terminals [FWD], [REV], and [X1] through [X7] of the control circuit.
x If an external frequency command potentiometer is connected to terminal [13], disconnect it.
x If an external apparatus is attached to terminal [PLC], disconnect it.
x Ensure that transistor output signals ([Y1] to [Y4]) and relay output signals ([Y5A] - [Y5C], and [30A/B/C]) will not be
turned ON.
x Disable the RS-485 communications link.
It is recommended that terminal [EN] be short-circuited for the measurement of the capacitance.
If negative logic is specified for the transistor output and relay output signals, they are considered ON when the
inverter is not running. Specify positive logic for them.
x Keep the surrounding temperature within 25 r10qC.

If " . . . . " does not appear on the LED monitor, the measurement has not started. Check the conditions listed in 1).
6) After " . . . . " has disappeared from the LED monitor, turn ON the main circuit power again.
7) Select Menu #5 "Maintenance Information" in Programming mode and note the reading (relative capacitance (%) of the DC

-------------------------------------------------------------------------------------------------------------------------------------------------------
7-4
[ 2 ] Measuring the capacitance of the DC link bus capacitor under ordinary operating conditions
When bit 3 of H98 data is 1, the inverter automatically measures the capacitance of the DC link bus capacitor under ordinary
operating conditions when the power is turned OFF. This measurement requires setting up the load conditions for ordinary
operation and measuring the reference capacitance when the inverter is introduced to the practical operation, using the setup
procedure given below.
------------------------------------------------ Reference capacitance setup procedure ---------------------------------------------------1) Set function code H98 (Protection/maintenance function) to enable the user to specify the judgment criteria for the service
life of the DC link bus capacitor (Bit 3 = 1) (refer to function code H98).
2) Turn OFF all run commands.
3) Make the inverter ready to be turned OFF under ordinary operating conditions.
4) Set both function codes H42 (Capacitance of DC link bus capacitor) and H47 (Initial capacitance of DC link bus capacitor)
to "0000."
5) Turn OFF the inverter, and the following operations are automatically performed.
The inverter measures the discharging time of the DC link bus capacitor and saves the result in function code H47 (Initial
capacitance of DC link bus capacitor).
The conditions under which the measurement has been conducted will be automatically collected and saved.
During the measurement, " . . . . " will appear on the LED monitor.
6) Turn ON the inverter again.
Confirm that H42 (Capacitance of DC link bus capacitor) and H47 (Initial capacitance of DC link bus capacitor) hold right
values. Shift to Menu #5 "Maintenance Information" and confirm that the relative capacitance (ratio to full capacitance) is
100%.
The condition given above produces a rather large measurement error. If this mode gives you a lifetime alarm, set H98
(Maintenance operation) back to the default setting (Bit 3 (Select life judgment threshold of DC link bus capacitor) =
0) and conduct the measurement under the condition at the time of factory shipment.
[ 3 ] Early warning of lifetime alarm
For the components listed in Table 7.3, the inverter can issue an early warning of lifetime alarm LIFE at one of the transistor
output terminals ([Y1] to [Y4]) and the relay contact terminals ([Y5A] - [Y5C], and [30A/B/C]) as soon as any of the levels
specified in Table 7.3 has been exceeded.
The early warning signal is also turned ON when a lock condition on the internal air circulation DC fan (provided on 200 V
class series inverters with a capacity of 45 kW or above; on 400 V class series inverters with a capacity of 75 kW or above) has
been detected.
7.4 Measurement of Electrical Amounts in Main Circuit
Because the voltage and current of the power supply (input, primary circuit) of the main circuit of the inverter and those of the
motor (output, secondary circuit) contain harmonic components, the readings may vary with the type of the meter. Use meters
indicated in Table 7.4 when measuring with meters for commercial frequencies.
The power factor cannot be measured by a commercially available power-factor meter that measures the phase difference
between the voltage and current. To obtain the power factor, measure the power, voltage and current on each of the input and
output sides and use the following formula.
„ Three-phase input
Power factor =
Electric power (W)
× 100 %
3 × Voltage (V) × Current (A)
7-5
MAINTENANCE AND INSPECTION
Hereafter, each time the inverter is turned OFF, it automatically measures the discharging time of the DC link bus capacitor if
the above conditions are met. Periodically check the relative capacitance of the DC link bus capacitor (%) with Menu #5
"Maintenance Information" in Programming mode.
Chap. 7
If the measurement has failed, "0001" is entered into both H42 and H47. Remove the factor of the failure and
conduct the measurement again.

7.5 Insulation Test
Since the inverter has undergone an insulation test before shipment, avoid making a Megger test at the customer's site.
If a Megger test is unavoidable for the main circuit, observe the following instructions; otherwise, the inverter may be damaged.
A withstand voltage test may also damage the inverter if the test procedure is wrong. When the withstand voltage test is
necessary, consult your IMO representative.
(1) Megger test of main circuit
1) Use a 500 VDC Megger and shut off the main power supply without fail before measurement.
2) If the test voltage leaks to the control circuit due to the wiring, disconnect all the wiring from the control circuit.
3) Connect the main circuit terminals with a common line as shown in Figure 7.2.
4) The Megger test must be limited to across the common line of the main circuit and the ground ( ).
5) Value of 5 M: or more displayed on the Megger indicates a correct state. (The value is measured on an inverter alone.)
Figure 7.2 Main Circuit Terminal Connection for Megger Test
(2) Insulation test of control circuit
Do not make a Megger test or withstand voltage test for the control circuit. Use a high resistance range tester for the control
circuit.
1) Disconnect all the external wiring from the control circuit terminals.
2) Perform a continuity test to the ground. One M: or a larger measurement indicates a correct state.
(3) Insulation test of external main circuit and sequence control circuit
Disconnect all the wiring connected to the inverter so that the test voltage is not applied to the inverter.

4-pole standard motor
Rated capacity is calculated assuming the rated output voltage as 220 V for 200 V class series and 440 V for 400 V class series.
Output voltage cannot exceed the power supply voltage.
To use the inverter with the carrier frequency of 3 kHz or more at the surrounding temperature of 40°C or higher, manage the load so that the current
comes to be within the rated ones enclosed in parentheses ( ) in continuous running.
*5 Voltage unbalance (%) = Max. voltage (V) - Min. voltage (V) × 67 (IEC 61800 - 3)
Three - phase average voltage (V)
If this value is 2 to 3%, use an optional AC reactor (ACR).
*6 Required when a DC reactor (DCR) is used.
*7 Average braking torque for the motor running alone. (It varies with the efficiency of the motor.)
*8 A DC reactor (DCR) is optionally provided. Note that inverters with a capacity of 55 kW in VT mode and inverters with 75 kW or above in all modes
require a DCR to be connected. Be sure to connect it to those inverters.

Chapter 9 CONFORMITY WITH STANDARDS
9.1 Compliance with UL Standards and Canadian Standards (cUL certification)
9.1.1 General
Originally, the UL standards were established by Underwriters Laboratories, Inc. as private criteria for
inspections/investigations pertaining to fire/accident insurance in the USA. Later, these standards were authorized as the
official standards to protect operators, service personnel and the general populace from fires and other accidents in the USA.
cUL certification means that UL has given certification for products to clear CSA Standards. cUL certified products are
equivalent to those compliant with CSA Standards.
9.1.2 Considerations when using JAGUAR VXG in systems to be certified by UL and cUL
If you want to use the IMO series of inverters as a part of UL Standards or CSA Standards (cUL certified) certified product,
refer to the related guidelines described on pages ix to xii.
9.2 Compliance with European Standards
The CE marking on IMO products indicates that they comply with the essential requirements of the Electromagnetic
Compatibility (EMC) Directive 2004/108/EC and Low Voltage Directive 2006/95/EC which are issued by the Council of the
European Communities
The products comply with the following standards
Basic type
EMC filter built-in type
EMC Directives
Depends upon a filter dedicated to
IMO inverters*
Low Voltage Directive
EN61800-5-1: 2003
Safety Standard
EN954-1: Category 3
EN61800-3 : 2004
Immunity : Second environment (Industrial)
Emission : Category C3
* If connected with an external EMC filter dedicated to IMO inverters, the basic type of inverters that bear a CE marking but
have no built-in EMC filter becomes compliant with these EMC Directives.
9.3 Compliance with EMC Standards
9.3.1 General
The CE marking on inverters does not ensure that the entire equipment including our CE-marked products is compliant with
the EMC Directive. Therefore, CE marking for the equipment shall be the responsibility of the equipment manufacturer. For
this reason, IMO’s CE mark is indicated under the condition that the product shall be used within equipment meeting all
requirements for the relevant Directives. Instrumentation of such equipment shall be the responsibility of the equipment
manufacturer.
Generally, machinery or equipment includes not only our products but other devices as well. Manufacturers, therefore, shall
design the whole system to be compliant with the relevant Directives.
In addition, to satisfy the requirements noted above, use the EMC filter built-in type of inverters or the combination of the
basic type of inverters that have no built-in EMC filter and an external filter (option) dedicated to IMO inverters. In either
case, mount inverters in accordance with the installation procedure given below. To ensure the compliance, it is
recommended that inverters be mounted in a metal panel.
Our EMC compliance test is performed under the following conditions.
Wiring length (of the shielded cable) between the inverter (EMC filter built-in type) and motor: 5m
To use IMO inverters in combination with a PWM converter, the basic type of inverters having no built-in EMC
filter should be used. Use of an EMC filter built-in type may increase heat of capacitors in the inverter, resulting in
a break. In addition, the effect of the EMC filter can no longer be expected.
9-1
CONFORMITY WITH STANDARDS
CAUTION
The EMC filter built-in type of the IMO inverters is categorized as "Category C3" of the EN61800-3. It is not designed for
use in a domestic environment. It may interfere with the operations of home appliances or office equipment due to noise
emitted from it.
Chap. 9
9.3.2 Recommended installation procedure
To make the machinery or equipment fully compliant with the EMC Directive, have certified technicians wire the motor and
inverter in strict accordance with the procedure described below.
„ In the case of EMC filter built-in type of inverter
1) Mount the inverter on a grounded panel or metal plate. Use shielded wires for the motor cable and route the cable as short
as possible. Firmly clamp the shield to the metal plate to ground it. Further, connect the shielding layer electrically to the
grounding terminal of the motor. Separate the input and output wires as far as possible, using wiring guides.
For inverters with a capacity of 5.5 to 11 kW, connect the input grounding wire to the grounding terminal at the front,
left-hand side, and the output grounding wire to that on the main circuit terminal block. (Refer to Figure 9.1.)

Output wires
Figure 9.1 Wiring for EMC Filter Built-in Type Inverters with a Capacity of 5.5 to 11 kW
2) For connection to inverter's control terminals and for connection of the RS-485 communication signal cable, use shielded
wires. As with the motor, clamp the shields firmly to a grounded panel.
3) If noise from the inverter exceeds the permissible level, enclose the inverter and its peripherals within a metal panel as
shown in Figure 9.2.
Figure 9.2 Mounting the Inverter in a Metal Panel
„ In case an EMC-compliant filter (optional) is externally used
1) Mount the inverter and the filter on a grounded panel or metal plate. Use shielded wires for the motor cable and route the
cable as short as possible. Firmly clamp the shields to the metal plate to ground them. Further, connect the shielding
layers electrically to the grounding terminal of the motor.
2) For connection to inverter's control terminals and for connection of the RS-485 communication signal cable, use shielded
wires. As with the motor, clamp the shields firmly to a grounded panel.
3) If noise from the inverter exceeds the permissible level, enclose the inverter and its peripherals within a metal panel as
shown in Figure 9.3.
Figure 9.3 Mounting the Inverter with EMC-compliant Filter in a Metal Panel
9-2
9.3.3 Leakage current of EMC-filter built-in type of inverters
An EMC filter uses grounding capacitors for noise suppression which increase leakage current. When using an EMC-filter
built-in type of inverters, therefore, check whether there is no problem with electrical systems.
Three-Phase PDS (Power Drive System) with touch currents t 3.5 mA AC or t 10 mA DC
As the touch current (leakage current) of inverters with EMC-filter is relatively high, it is of essential importance to
always assure a reliable connection to Protective Earth (PE).
In Table 9.1, for the inverter types whose leakage currents are equal to or exceed the critical value of 35 mA AC or 10 mA
DC (IEC 61800-5-1), the minimum cross sectional area of the PE-conductor should be:
- 10 mm2 (Cu-conductors)
- 16 mm2 (Al-conductors)
An electric shock could occur.

9.4 Harmonic Component Regulation in the EU
9.4.1 General comments
When you use general-purpose industrial inverters in the EU, the harmonics emitted from the inverter to power lines are
strictly regulated as stated below.
If an inverter whose rated input is 1 kW or less is connected to public low-voltage power supply, it is regulated by the
harmonics emission regulations from inverters to power lines (with the exception of industrial low-voltage power lines).
Refer to Figure 9.4 below for details.

* When supplying three-phase 200 VAC power stepped down from a three-phase 400 VAC power line using a transformer, the level of
harmonic flow from the 400 VAC line will be regulated.
Note 1) Inverter types marked with — in the table above are compliant with the EN61000-3-2 (+A14), so they may be connected to public
low-voltage power supply unconditionally.
Conditions apply when connecting models marked with "—". To connect them to public low-voltage power supply, you need to
obtain permission from the local electric power supplier. In general, you will need to provide the supplier with the harmonics
current data of the inverter. To obtain the data, contact your IMO representative.
9.5 Compliance with the Low Voltage Directive in the EU
9.5.1 General
General-purpose inverters are regulated by the Low Voltage Directive in the EU. IMO Precision Controls Ltd states that all
our inverters with CE marking are compliant with the Low Voltage Directive.
9.5.2 Points for consideration when using the IMO series in a system to be certified by the Low Voltage
Directive in the EU
If you want to use the IMO series of inverters in systems/equipment in the EU, refer to the guidelines on pages v to viii.

9.6 Compliance with EN954-1, Category 3
9.6.1 General
In IMO series of inverters, opening the hardware circuit between terminals [EN] and [PLC] stops the output transistor,
coasting the motor to a stop. (EN: Enable input) This is the safety stop function prescribed in EN60204-1, Category 0
(Uncontrolled stop) and compliant with EN954-1, Category 3.
Note: Depending on applications, additional measures may be necessary (for end-user) to apply such as ‘brake function’ to
prevent movement and motor terminal protection against possible electrical hazard(s).
Use of terminals [EN] and [PLC] eliminates the need of external safety circuit breakers while conventional inverters need
those breakers to configure the EN954-1 Category 3 compliant safety system.
9.6.2 EN954-1
Chap. 9
European Standard EN954-1 (Safety of machinery–Safety related parts of control systems) prescribes the basic safety
requirements for machinery categorized according to the requirement level. Category 3 represents the requirements that the
machinery shall be designed with redundancy so that a single fault does not lead to the loss of the safety function. Table 9.3
shows an outline of the category levels and their safety requirements. (For detailed requirements refer to EN 954-1)
Table 9.3
Summary of requirements
System behavior
B
Safety related parts of control systems and/or their safety
devices and their components shall be designed,
constructed, selected, assembled and combined in
accordance with the relevant standards so that they can
withstand the expected influence.
The occurrence of a fault can lead to the
loss of the safety function.
1
Requirements of Category B shall apply.
Well-tried safety principles and well-tried components shall
be used.
The occurrence of a fault can lead to the
loss of the safety function, but the
probability of occurrence is lower than
for Category B.
2
Requirements of Category 1 shall apply.
The occurrence of a fault can lead to the
loss of the safety function between the
checks.
The safety function shall be checked at intervals suitable
for the machinery.
3
Requirements of Category 1 shall apply.
Safety-related parts shall be designed, so that:
- a single fault in any of these parts does not lead to the
loss of the safety function, and
- a single fault is detected whenever reasonably
practicable.
When the single fault occurs, the safety
function is still maintained.
Accumulation of undetected faults can
lead to the loss of the safety function.
4
Requirements of Category 1 shall apply.
Safety-related parts shall be designed, so that a single fault
is detected during or prior to the next demand on the safety
function. If this is not possible, an accumulation of faults
shall not lead to the loss of the safety function.
When faults occur, the safety function is
still maintained.

9.6.3 Notes
(1) Wiring for terminal [EN]
- When using terminal [EN], be sure to remove the short-circuit wire from terminals [EN] and [PLC], which has been
connected at the shipment.
- '[EN] & [PLC]' terminals are safety related wire connections and therefore careful installation practices shall be applied
to ensure no 'short-circuit(s)' can occur to these connections.
- For opening and closing the hardware circuit between terminals [EN] and [PLC], use safety approved components such
as safety switches and safety relays that comply with EN954-1, Category 3 or higher to ensure a complete shutoff.
- Be sure to use shielded wires for connecting terminals [EN] and [PLC] and ground the shielding layer. Do not
connect/mix any other control signal wire within the same shielded core.
- It is the responsibility of the machinery manufacturer to guarantee that a short-circuiting or other fault does not occur in
wiring of external safety components between terminals [EN] and [PLC].
Fault examples:
• Terminals [EN] and [PLC] are short-circuited due to the wiring being caught in the door of the control panel so that a
current continues to flow in terminal [EN] although the safety component is OFF and therefore the safety function
will/may NOT operate
• The wiring is in contact with any other wire so that a current continues to flow in terminal [EN] and therefore the
safety function will/may NOT operate
(2) Other notes
- When configuring the product safety system with this safety stop function, make a risk assessment of not only the
external equipment and wiring connected to terminal [EN] but also the whole system including other equipment,
devices and wiring against the product safety system required by the machinery manufacturer under the manufacturer's
responsibility in order to confirm that the whole system conforms to the product safety system required by the
machinery manufacturer.
In addition, as preventive maintenance, the machinery manufacturer must perform periodical inspections to check that
the product safety system properly functions.
- To make the inverter compliant with EN954-1, Category 3, it is necessary to install the inverter on a control panel with
the enclosure rating of IP54 or above.
This safety stop function coasts the motor to a stop. When a mechanical brake is used to stop or hold the motor for the
sake of the product safety system of whole system, do not use the inverter's control signals such as output from terminal
[Y]. (Using control signals does not satisfy the safety standards because of software intervention.) Use safety
components complying with EN954-1, Category 3 or higher to activate mechanical brakes.
- The safety shutdown circuit between terminal [EN] input section and inverter's output shutdown section is dualconfigured (redundant circuit) so that an occurrence of a single fault does not detract the safety stop function.
If a single fault is detected in the safety shutdown circuit, the inverter coasts the motor to a stop even with the terminal
[EN]-[PLC] state being ON, as well as outputting an alarm to external equipment. (Note that the alarm output function
is not guaranteed to all of single faults.)
- This safety stop function may not completely shut off the power supply to the motor electrically. Before performing
wiring or maintenance jobs, be sure to disconnect/isolate the input power to the inverter and wait at least 5 minutes for
22 kW or below of inverters, and at least 10 minutes for 30 kW or above.
