Safety Precautions
Confirmations upon Delivery
CAUTION
• Never install an Inverter that is damaged or missing components.
Doing so can result in injury.
Installation
CAUTION
• Always hold the case when carrying the Inverter.
If the Inverter is held by the front cover, the main body of the Inverter may fall, possibly resulting in injury.
• Attach the Inverter to a metal or other noncombustible material.
Fire can result if the Inverter is attached to a combustible material.
• Install a cooling fan or other cooling device when installing more than one Inverter in the same
enclosure so that the temperature of the air entering the Inverters is below 45°C.
Overheating can result in fires or other accidents.
Wiring
WARNING
• Always turn OFF the input power supply before wiring terminals.
Otherwise, an electric shock or fire can occur.
• Wiring must be performed by an authorized person qualified in electrical work.
Otherwise, an electric shock or fire can occur.
• Be sure to ground the ground terminal. (200 V class: Ground to 100 Ω or less, 400 V class: Ground
to 10 Ω or less)
Otherwise, an electric shock or fire can occur.
• Always check the operation of any emergency stop circuits after they are wired.
Otherwise, there is the possibility of injury. (Wiring is the responsibility of the user.)
• Never touch the output terminals directly with your hands or allow the output lines to come into contact with the Inverter case. Never short the output circuits.
Otherwise, an electric shock or ground short can occur.
CAUTION
• Check to be sure that the voltage of the main AC power supply satisfies the rated voltage of the
Inverter.
Injury or fire can occur if the voltage is not correct.
• Do not perform voltage withstand tests on the Inverter.
Otherwise, semiconductor elements and other devices can be damaged.
• Connect braking resistors, Braking Resistor Units, and Braking Units as shown in the I/O wiring
examples.
Otherwise, a fire can occur.
• Tighten all terminal screws to the specified tightening torque.
Otherwise, a fire may occur.
• Do not connect AC power to output terminals U, V, and W.
The interior parts of the Inverter will be damaged if voltage is applied to the output terminals.
• Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits.
The Inverter can be damaged or internal parts burnt if these devices are connected.
iii
CAUTION
• Do not connect electromagnetic switches or contactors to the output circuits.
If a load is connected while the Inverter is operating, surge current will cause the overcurrent protection circuit inside the
Inverter to operate.
Setting User Constants
CAUTION
• Disconnect the load (machine, device) from the motor before performing rotational autotuning.
The motor may turn, possibly resulting in injury or damage to equipment. Also, motor constants cannot be correctly set
with the motor attached to a load.
• Stay clear of the motor during rotational autotuning.
The motor may start operating suddenly when stopped, possibly resulting in injury.
Trial Operation
WARNING
• Check to be sure that the front cover is attached before turning ON the power supply.
An electric shock may occur.
• Do not come close to the machine when the fault reset function is used. If the alarmed is cleared,
the machine may start moving suddenly.
Also, design the machine so that human safety is ensured even when it is restarted.
Injury may occur.
• Provide a separate emergency stop switch; the Digital Operator STOP Key is valid only when its
function is set.
Injury may occur.
• Reset alarms only after confirming that the RUN signal is OFF.
Injury may occur.
CAUTION
• Don't touch the radiation fins (heatsink), braking resistor, or Braking Resistor Unit. These can
become very hot.
Otherwise, a burn injury may occur.
• Be sure that the motor and machine is within the applicable ranges before starting operation.
Otherwise, an injury may occur.
• Provide a separate holding brake if necessary.
Always construct the external sequence to confirm that the holding brake is activated in the event
of an emergency, a power failure, or an abnormality in the Inverter.
Failure to observe this caution can result in injury.
• If using an Inverter with an elevator, take safety measures on the elevator to prevent the elevator
from dropping.
Failure to observe this caution can result in injury.
• Don't check signals while the Inverter is running.
Otherwise, the equipment may be damaged.
• Be careful when changing Inverter settings. The Inverter is factory set to suitable settings.
Otherwise, the equipment may be damaged.
iv
Maintenance and Inspection
WARNING
• Do not touch the Inverter terminals. Some of the terminals carry high voltages and are extremely
dangerous.
Doing so can result in electric shock.
• Always have the protective cover in place when power is being supplied to the Inverter. When
attaching the cover, always turn OFF power to the Inverter through the MCCB.
Doing so can result in electric shock.
• After turning OFF the main circuit power supply, wait until the CHARGE indicator light goes out
before performance maintenance or inspections.
The capacitor will remain charged and is dangerous.
• Maintenance, inspection, and replacement of parts must be performed only by authorized personnel.
Remove all metal objects, such as watches and rings, before starting work. Always use grounded tools.
Failure to heed these warning can result in electric shock.
CAUTION
• A CMOS IC is used in the control board. Handle the control board and CMOS IC carefully. The
CMOS IC can be destroyed by static electricity if touched directly.
The CMOS IC can be destroyed by static electricity if touched directly.
• Do not change the wiring, or remove connectors or the Digital Operator, during operation.
Doing so can result in personal injury.

• Install the Inverter in a location without excessive oscillation.
• Install the Inverter in a location free from chlorides.
• Install the Inverter in a location not in direct sunlight.
Controlling the Ambient Temperature
To enhance the reliability of operation, the Inverter should be installed in an environment free from extreme
temperature increases. If the Inverter is installed in an enclosed environment, such as a box, use a cooling fan
or air conditioner to maintain the internal air temperature below 45°C.
Protecting the Inverter from Foreign Matter
Place a cover over the Inverter during installation to shield it from metal power produced by drilling.
Always remove the cover from the Inverter after completing installation. Otherwise, ventilation will be
reduced, causing the Inverter to overheat.

2. The output current capacity of the +V terminal is 20 mA.
3. Disable the stall prevention during deceleration (set constant L3-04 to 0) when using a Braking Resistor
Unit. If this user constant is not changed to disable stall prevention, the system may not stop during deceleration.
4. Main circuit terminals are indicated with double circles and control circuit terminals are indicated with single
circles.
5. The wiring for a motor with a cooling fan is not required for self-cooling motors.
6. PG circuit wiring (i.e., wiring to the PG-B2 Card) is not required for open-loop vector control.
7. Sequence input signals S1 to S12 are labeled for sequence connections (0 V common and sinking mode)
for no-voltage contacts or NPN transistors. These are the default settings.
For PNP transistor sequence connections (+24V common and sourcing mode) or to provide a 24-V external power supply, refer toTable 2.13.
8. The master speed frequency reference can set to input either a voltage (terminal A1) or current (terminal
A2) by changing the setting of parameter H3-13. The default setting is for a voltage reference input.
9. The multi-function analog output is a dedicated meter output for an analog frequency meter, ammeter, voltmeter, wattmeter, etc. Do not use this output for feedback control or for any other control purpose.
10.DC reactors to improve the input power factor built into 200 V Class Inverters for 18.5 to 110 kW and 400
V Class Inverters for 18.5 to 300 kW. A DC reactor is thus an option only for Inverters for 15 kW or less.
11.Set parameter L8-01 to 1 when using a breaking resistor (ERF). When using a Braking Resistor Unit, a
shutoff sequence for the power supply must be made using a thermal relay trip.

Wiring the Main Circuits
This section describes wiring connections for the main circuit inputs and outputs.
Wiring Main Circuit Inputs
Observe the following precautions for the main circuit power supply input.
Installing a Molded-case Circuit Breaker
Always connect the power input terminals (R, S, and T) and power supply via a molded-case circuit breaker
(MCCB) suitable for the Inverter.
• Choose an MCCB with a capacity of 1.5 to 2 times the Inverter's rated current.
• For the MCCB's time characteristics, be sure to consider the Inverter's overload protection (one minute at
150% of the rated output current).
• If the same MCCB is to be used for more than one Inverter, or other devices, set up a sequence so that the
power supply will be turned OFF by a fault output, as shown in Fig 2.6.

Fault output
(NC)
* For 400 V class Inverters, connect a 400/200 V transformer.
Fig 2.6 MCCB Installation
Installing a Ground Fault Interrupter
Inverter outputs use high-speed switching, so high-frequency leakage current is generated. Therefore, at the
Inverter primary side, use a ground fault interrupter to detect only the leakage current in the frequency range
that is hazardous to humans and exclude high-frequency leakage current.
• For the special-purpose ground fault interrupter for Inverters, choose a ground fault interrupter with a sen-
sitivity amperage of at least 30 mA per Inverter.
• When using a general ground fault interrupter, choose a ground fault interrupter with a sensitivity amper-
age of 200 mA or more per Inverter and with an operating time of 0.1 s or more.
2-14
Wiring Main Circuit Terminals
Installing a Magnetic Contactor
If the power supply for the main circuit is to be shut off during a sequence, a magnetic contactor can be used.
When a magnetic contactor is installed on the primary side of the main circuit to forcibly stop the Inverter,
however, the regenerative braking does not work and the Inverter will coast to a stop.
• The Inverter can be started and stopped by opening and closing the magnetic contactor on the primary side.
Frequently opening and closing the magnetic contactor, however, may cause the Inverter to break down.
Start and stop the Inverter at most once every 30 minutes.
• When the Inverter is operated with the Digital Operator, automatic operation cannot be performed after
recovery from a power interruption.
• If the Braking Resistor Unit is used, program the sequence so that the magnetic contactor is turned OFF by
the contact of the Unit's thermal overload relay.
Connecting Input Power Supply to the Terminal Block
Input power supply can be connected to any terminal R, S or T on the terminal block; the phase sequence of
input power supply is irrelevant to the phase sequence.
Installing an AC Reactor
If the Inverter is connected to a large-capacity power transformer (600 kW or more) or the phase advancing
capacitor is switched, an excessive peak current may flow through the input power circuit, causing the converter unit to break down.
To prevent this, install an optional AC Reactor on the input side of the Inverter or a DC reactor to the DC reactor connection terminals.
This also improves the power factor on the power supply side.
Installing a Surge Absorber
Always use a surge absorber or diode for inductive loads near the Inverter. These inductive loads include magnetic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.
Installing a Noise Filter on Power Supply Side
Install a noise filter to eliminate noise transmitted between the power line and the Inverter.

Wiring the Output Side of Main Circuit
Observe the following precautions when wiring the main output circuits.
Connecting the Inverter and Motor
Connect output terminals U, V, and W to motor lead wires U, V, and W, respectively.
Check that the motor rotates forward with the forward run command. Switch over any two of the output terminals to each other and reconnect if the motor rotates in reverse with the forward run command.
Never Connect a Power Supply to Output Terminals
Never connect a power supply to output terminals U, V, and W. If voltage is applied to the output terminals,
the internal circuits of the Inverter will be damaged.
Never Short or Ground Output Terminals
If the output terminals are touched with bare hands or the output wires come into contact with the Inverter casing, an electric shock or grounding will occur. This is extremely hazardous. Do not short the output wires.
Do Not Use a Phase Advancing Capacitor or Noise Filter
Never connect a phase advancing capacitor or LC/RC noise filter to an output circuit. The high-frequency
components of the Inverter output may result in overheating or damage to these part or may result in damage
to the Inverter or cause other parts to burn.
Do Not Use an Electromagnetic Switch
Never connect an electromagnetic switch (MC) between the Inverter and motor and turn it ON or OFF during
operation. If the MC is turned ON while the Inverter is operating, a large inrush current will be created and the
overcurrent protection in the Inverter will operate.
2-16
Wiring Main Circuit Terminals
When using an MC to switch to a commercial power supply, stop the Inverter and motor before operating the
MC. Use the speed search function if the MC is operated during operation. If measures for momentary power
interrupts are required, use a delayed release MC.
Installing a Thermal Overload Relay
This Inverter has an electronic thermal protection function to protect the motor from overheating. If, however,
more than one motor is operated with one Inverter or a multi-polar motor is used, always install a thermal
relay (THR) between the Inverter and the motor and set L1-01 to 0 (no motor protection). The sequence
should be designed so that the contacts of the thermal overload relay turn OFF the magnetic contactor on the
main circuit inputs.
Installing a Noise Filter on Output Side
Connect a noise filter to the output side of the Inverter to reduce radio noise and inductive noise.

Countermeasures Against Inductive Noise
As described previously, a noise filter can be used to prevent inductive noise from being generated on the output side. Alternatively, cables can be routed through a grounded metal pipe to prevent inductive noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces inductive noise.

Countermeasures Against Radio Interference
Radio noise is generated from the Inverter as well as from the input and output lines. To reduce radio noise,
install noise filters on both input and output sides, and also install the Inverter in a totally enclosed steel box.
The cable between the Inverter and the motor should be as short as possible.

Cable Length between Inverter and Motor
If the cable between the Inverter and the motor is long, the high-frequency leakage current will increase, causing the Inverter output current to increase as well. This may affect peripheral devices. To prevent this, adjust
the carrier frequency (set in C6-01, C6-02) as shown in Table 2.6. (For details, refer to Chapter 5 User Constants.)

Ground Wiring
Observe the following precautions when wiring the ground line.
• Always use the ground terminal of the 200 V Inverter with a ground resistance of less than 100 Ω and that
of the 400 V Inverter with a ground resistance of less than 10 Ω.
• Do not share the ground wire with other devices, such as welding machines or power tools.
• Always use a ground wire that complies with technical standards on electrical equipment and minimize the
length of the ground wire.
Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode and the
ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.
• When using more than one Inverter, be careful not to loop the ground wire.

Connecting the Braking Resistor (ERF)
A Braking Resistor that mounts to the Inverter can be used with 200 V and 400 V Class Inverters with outputs
from 0.4 to 3.7 kW.
Connect the braking resistor as shown in Fig 2.13.

Fig 2.13 Connecting the Braking Resistor
The braking resistor connection terminals are B1 and B2. Do not connect to any other terminals. Connecting
to any terminals other than B1 or B2 can cause the resistor to overheat, resulting in damage to the equipment.
IMPORTANT
Connecting the Braking Resistor Unit (LKEB) and Braking Unit (CDBR)
Use the following settings when using a Braking Resistor Unit. Refer to User Constants on page 10-19 for connection methods for a Braking Resistor Unit.
A Braking Resistor that mounts to the Inverter can also be used with Inverters with outputs from 0.4 to
3.7 kW.

0 (Disables overheat protection)
L3-04 (Stall prevention selection during deceleration)

0 (Disables stall prevention function)
3 (Enables stall prevention function with braking resistor)
L8-01 is used when a braking resistor without thermal overload relay trip contacts (ERF type mounted to
Inverter) is connected.
The Braking Resistor Unit cannot be used and the deceleration time cannot be shortened by the Inverter if L304 is set to 1 (i.e., if stall prevention is enabled for deceleration).

Wiring Control Circuit Terminals
Wire Sizes and Closed-loop Connectors
For remote operation using analog signals, keep the control line length between the Digital Operator or operation signals and the Inverter to 50 m or less, and separate the lines from high-power lines (main circuits or
relay sequence circuits) to reduce induction from peripheral devices.
When setting frequencies from an external frequency setter (and not from a Digital Operator), used shielded
twisted-pair wires and ground the shield to terminal E (G), as shown in the following diagram.

Wiring Control Circuit Terminals
Control Circuit Wiring Precautions
Observe the following precautions when wiring control circuits.
• Separate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/T2,
W/T3,
,
1,
2, and
3) and other high-power lines.
• Separate wiring for control circuit terminals MA, MB, MC, M1, and M2 (contact outputs) from wiring to
other control circuit terminals.
• Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating faults. Process
cable ends as shown in Fig 2.20.
• Connect the shield wire to terminal E (G).
• Insulate the shield with tape to prevent contact with other signal lines and equipment.

The wiring method is the same as the one used for straight solderless terminals. Refer to page 2-2-21. Observe
the following precautions when wiring.
• Separate the control signal lines for the PG Speed Control Card from main circuit lines and power lines.
• Connect the shield when connecting to a PG. The shield must be connected to prevent operational errors
caused by noise. Also, do not use any lines that are more than 100 m long. Refer to Fig 2.20 for details on
connecting the shield.
• Connect the shield to the shield terminal (E).
• Do not solder the ends of wires. Doing so may cause contact faults.
• When not using straight solderless terminals, strip the wires to a length of approximately 5.5 mm.

Modes
This section describes the Inverter's modes and switching between modes.
Inverter Modes
The Inverter's user constants and monitoring functions are organized in groups called modes that make it easier to read and set user constants.The Inverter is equipped with 5 modes.
The 5 modes and their primary functions are shown in the Table 3.2.
Table 3.2 Modes
Mode
Primary function(s)
Drive mode
The Inverter can be run in this mode.
Use this mode when monitoring values such as frequency references or output current, displaying fault information, or displaying the fault history.
Quick programming mode
Use this mode to reference and set the minimum user constants to operate the
Inverter (e.g., the operating environment of the Inverter and Digital Operator).
Advanced programming mode
Use this mode to reference and set all user constants.
Verify mode
Use this mode to read/set user constants that have been changed from their factoryset values.
Autotuning mode*
Use this mode when running a motor with unknown motor constants in the vector
control mode. The motor constants are calculated and set automatically.
This mode can also be used to measure only the motor line-to-line resistance.
* Always perform autotuning with the motor before operating using vector control. Autotuning mode will not be displayed during operation or when an error
has occurred. The default setting of the Inverter is for open-loop vector control 1 (A1-02 = 2).

Verify Mode
Verify mode is used to display any constants that have been changed from their default settings in a programming mode or by autotuning. “None” will be displayed if no settings have been changed.
Of the environment mode settings, only A1-02 will be displayed if it has been changed. Other environment
modes settings will not be displayed even if they have been changed from their default settings.
Even in verify mode, the same procedures can be used to change settings as are used in the programming
modes. Use the Increment, Decrement, and Shift/RESET Keys to change the frequency. The user constant will
be written and the monitor display will be returned to when the DATA/ENTER Key is pressed after changing
the setting.
Example Operations
An example of key operations is given below for when the following settings have been changed from their
default settings: b1-01 (Reference Selection), C1-01 (Acceleration Time 1), E1-01 (Input Voltage Setting), and

Autotuning Mode
Autotuning automatically tunes and sets the required motor constants when operating in the vector control
modes. Always perform autotuning before starting operation.
When V/f control has been selected, stationary autotuning for only line-to-line resistance can be selected.
When the motor cannot be disconnected from the load, perform stationary autotuning. Contact your Yaskawa
representatives to set motor constants by calculation.
The Inverter's autotuning function automatically determines the motor constants, while a servo system's autotuning function determines the size of a load, so these autotuning functions are fundamentally different. The
default setting of the Inverter is for open-loop vector control 1.
Example of Operation
Set the motor output power (in kW), rated voltage, rated current, rated frequency, rated speed, and number of
poles specified on the nameplate on the motor and then press the RUN Key. The motor is automatically run
and the motor constants measured based on these settings and autotuning will be set.
Always set the above items. Autotuning cannot be started otherwise, e.g., it cannot be started from the motor
rated voltage display.
Constants can be changed from the setting displays. Use the Increment, Decrement, and Shift/RESET Keys to
change the frequency. The user constant will be written and the monitor display will be returned to when the
DATA/ENTER Key is pressed after changing the setting.
The following example shows autotuning for open-loop vector control while operating the motor without
switching to motor 2.

Trial Operation Procedures
• Perform stationary autotuning for the line-to-line resistance only if the motor cable is 50 m or longer for
the actual installation or the load is heavy enough to produce stalling. Refer to the following section on
Autotuning for details on stationary autotuning.
Open-loop Vector Control 1 (A1-02 = 2)
Perform autotuning. If the motor can be operated, perform rotational autotuning. If the motor cannot be operated, perform stationary autotuning. Refer to the following section on Autotuning for details on autotuning.
Flux Vector Control (A1-02 = 3)
Perform autotuning. If the motor can be operated, perform rotational autotuning. If the motor cannot be operated, perform stationary autotuning. Refer to the following section on Autotuning for details on autotuning.
Open-loop Vector Control 2 (A1-02 = 4)
Perform autotuning. Be sure to perform rotational autotuning. Refer to the following section on Autotuning for
details on autotuning.
Autotuning
Use the following procedure to perform autotuning to automatically set motor constants when using the vector
control method, when the cable length is long, etc.
Setting the Autotuning Mode
One of the following three autotuning modes can be set.
• Rotational autotuning
• Stationary autotuning
• Stationary autotuning for line-to-line resistance only
Always confirm the precautions before autotuning before performing autotuning.
Rotational Autotuning (T1-01 = 0)
Rotational autotuning is used only for open-vector control. Set T1-01 to 0, input the data from the nameplate,
and then press the RUN Key on the Digital Operator. The Inverter will stop the motor for approximately
1 minute and then set the required motor constants automatically while operating the motor for approximately
1 minute.
Stationary Autotuning (T1-01 = 1)
Stationary autotuning is used for open-vector control or flux vector control. Set T1-01 to 1, input the data from
the nameplate, and then press the RUN Key on the Digital Operator. The Inverter will supply power to the stationary motor for approximately 1 minute and some of the motor constants will be set automatically. The
remaining motor constants will be set automatically the first time operation is started in drive mode.
4-9
Stationary Autotuning for Line-to-Line Resistance Only (T1-01 = 2)
Stationary autotuning for line-to-line resistance only can be used in any control method. This is the only autotuning possible for V/f control and V/f control with PG modes.
Autotuning can be used to prevent control errors when the motor cable is long (50 m or longer) or the cable
length has changed since installation or when the motor and Inverter have different capacities.
Set T1-01 to 2 for open-loop vector control, and then press the RUN Key on the Digital Operator. The Inverter
will supply power to the stationary motor for approximately 20 seconds and the Motor Line-to-Line Resistance (E2-05) and cable resistance will be automatically measured.
Precautions Before Using Autotuning
Read the following precautions before using autotuning.
• Autotuning the Inverter is fundamentally different from autotuning the servo system. Inverter autotuning
automatically adjusts parameters according to detected motor constants, whereas servo system autotuning
adjusts parameters according to the detected size of the load.
• When speed precision or torque precision is required at high speeds (i.e., 90% of the rated speed or higher),
use a motor with a rated voltage that is 20 V less than the input power supply voltage of the Inverter for
200V-class Inverters and 40 V less for 400V-class Inverters. If the rated voltage of the motor is the same as
the input power supply voltage, the voltage output from the Inverter will be unstable at high speeds and
sufficient performance will not be possible.
• Use stationary autotuning whenever performing autotuning for a motor that is connected to a load.
• Use rotational autotuning whenever performing autotuning for a motor that has fixed output characteris-
tics, when high precision is required, or for a motor that is not connected to a load.
• If rotational autotuning is performed for a motor connected to a load, the motor constants will not be found
accurately and the motor may exhibit abnormal operation. Never perform rotational autotuning for a motor
connected to a load.
• If the wiring between the Inverter and motor changes by 50 m or more between autotuning and motor
installation, perform stationary autotuning for line-to-line resistance only.
• If the motor cable is long (50 m or longer), perform stationary autotuning for line-to-line resistance only
even when using V/f control.
• The status of the multi-function inputs and multi-function outputs will be as shown in the following table
during autotuning. When performing autotuning with the motor connected to a load, be sure that the holding brake is not applied during autotuning, especially for conveyor systems or similar equipment.

IMPORTANT
4-10
1. Power will be supplied to the motor when stationary autotuning is performed even though the motor
will not turn. Do not touch the motor until autotuning has been completed.
2. When performing stationary autotuning connected to a conveyor or other machine, ensure that the
holding brake is not activated during autotuning.
Trial Operation Procedures
Precautions for Rotational and Stationary Autotuning
Lower the base voltage based on Fig 4.4 to prevent saturation of the Inverter’s output voltage when the rated
voltage of the motor is higher than the voltage of the power supply to the Inverter. Use the following procedure to perform autotuning.
1. Input the voltage of the input power supply to T1-03 (Motor rated voltage).
2. Input the results of the following formula to T1-05 (Motor base frequency):
(Base frequency from the motor’s nameplate × setting of T1-03)/(Rated voltage from motor’s nameplate)
3. Perform autotuning.
After completing autotuning, set E1-04 (Max. output frequency) to the base frequency from the motor’s nameplate.

IMPORTANT
1. When speed precision is required at high speeds (i.e., 90% of the rated speed or higher), set T1-03 (Motor
rated voltage) to the input power supply voltage × 0.9.
2. When operating at high speeds (i.e., 90% of the rated speed or higher), the output current will increase as
the input power supply voltage is reduced. Be sure to provide sufficient margin in the Inverter current.
Precautions after Rotational and Stationary Autotuning
If the maximum output frequency and base frequency are different, set the maximum output frequency (E104) after autotuning.

The factory setting depends on the Inverter capacity. Values are given for a 200 V class, 0.4 kW Inverter.
The setting range is 10% to 200% of the Inverter capacity.
For V/f control, the only setting that is possible is 2 (stationary autotuning for line-to-line resistance only).
For fixed output motors, set the base speed value.
For inverter motors or for specialized vector motors, the voltage or frequency may be lower than for general-purpose motors. Always confirm the information on the nameplate or in test reports. If the no-load values are known, input the no-load voltage in T1-03 and the no-load current in T1-05 to
ensure accuracy.
* 7. The settings that will ensure stable vector control are between 50% and 100% of the Inverter rating.
Refer to page 3-14 for Digital Operator displays during autotuning.

Application Settings
User constants are set as required in advanced programming mode (“ADV” will be displayed on the LCD
screen). All the constants that can be set in quick programming mode can also be displayed and set in
advanced programming mode.
Setting Examples
The following are examples of settings for applications.
• When using an Inverter-mounted braking resistor (ERF), set L8-01 to 1 to enable ERF braking resistor
overheating protection.
• To prevent the machine from being operated in reverse, set b1-04 to 1 to disable reverse operation.
• To increase the speed of a 60 Hz motor by 10%, set E1-04 to 66.0 Hz.
• To use a 0 to 10-V analog signal for a 60 Hz motor for variable-speed operation between 0 and 54 Hz (0%
to 90% speed deduction), set H3-02 to 90.0%.
• To control speed between 20% and 80% to ensure smooth gear operation and limit the maximum speed of
the machine, set d2-01 to 80.0% and set d2-02 to 20.0%.
No-load Operation
To being no-load operation (without connecting the machine and the motor), press the LOCAL/REMOTE Key
on the Digital Operator to change to LOCAL mode (the SEQ and REF indicators on the Digital Operator
should be OFF).
Always confirm safety around the motor and machine before starting Inverter operation from the Digital
Operator. Confirm that the motor works normally and that no errors are displayed at the Inverter.
Jog Frequency Reference (d1-17, default: 6.00 Hz) can be started and stopped by pressing and releasing the
JOG Key on the Digital Operator. If the external sequence prevent operation from the Digital Operator, confirm that emergency stop circuits and machine safety mechanisms are functioning, and then start operation in
REMOTE mode (i.e., with a signal from the control signal terminals). The safety precautions must always be
taken before starting the Inverter with the motor connected to the machine.
Both a RUN command (forward or reverse) and a frequency reference (or multi-step speed reference) must
be provided to start Inverter operation.
Input these commands and reference regardless of the operation method (i.e., LOCAL of REMOTE).
INFO
Loaded Operation
Connect the machine to the motor and then start operation as described for no-load operation (i.e., from the
Digital Operator or by using control circuit terminal signals).
Connecting the Load
• After confirming that the motor has stopped completely, connect the mechanical system.
• Be sure to tighten all the screws when securing the motor shaft to the mechanical system.
4-14
Trial Operation Procedures
Operation using the Digital Operator
• Use the Digital Operator to start operation in LOCAL mode in the same way as in no-load operation.
• If fault occurs during operation, make sure the STOP Key on the Digital Operator is easily accessible.
• At first, set the frequency reference to a low speed of one tenth the normal operating speed.
Checking Operating Status
• Having checked that the operating direction is correct and that the machine is operating smoothly at slow
speed, increase the frequency reference.
• After changing the frequency reference or the rotation direction, check that there is no oscillation or abnor-
mal sound from the motor. Check the monitor display to ensure that U1-03 (Output Current) is not too
high.
• Refer to Adjustment Suggestions on page 4-16 if hunting, vibration, or other problems originating in the
control system occur.
Check and Recording User Constants
Use verify mode (“VERIFY” will be displayed on the LCD screen) to check user constants that have been
changed for trial operation and record them in a user constant table.
Any user constants that have been change by autotuning will also be displayed in verify mode.
If required, the copy function in constants o3-01 and o3-02 displayed in advanced programming mode can be
used to copy the changed settings from the Inverter to a recording area in the Digital Operator. If changed settings are saved in the Digital Operator, they can be easily copied back to the Inverter to speed up system
recovery if for any reason the Inverter has to be replaced.
The following functions can also be used to manage user constants.
• Recording user constants
• Setting access levels for user constants
• Setting a password
Recording User Constants (o2-03)
If o2-03 is set to 1 after completing trial operation, the settings of user constants will be saved in a separate
memory area in the Inverter. Later, after Inverter settings have been changed, the user constants can be initialized to the settings saved in the separate memory area when o2-03 was set to 1 by setting A1-03 (Initialize) to
1110.
User Constant Access Levels (A1-01)
A1-01 can be set to 0 (monitoring-only) to prevent user constants from being changed. A1-01 can also be set
to 1 (User-specified Constants) and used along with A2 constants to display only constants required by the
machine or application in a programming mode.
Password (A1-04 and A1-05)
When the access level is set to monitoring-only (A1-01 = 0), a password can be set so that user constants will
be displayed only when the correct password is input.

Adjustment Suggestions
If hunting, vibration, or other problems originating in the control system occur during trial operation,

• Do not change the Torque Compensation Gain (C4-01) from its default setting of 1.00 when using open-
loop vector control 1.
• If speeds are inaccurate during regeneration in open-loop vector control 1, enable Slip Compensation Dur-

• Use slip compensation to improve speed precision during V/f control (A1-02 = 0).
Set the Motor Rated Current (E2-01), Motor Rated Slip (E2-02), and Motor No-load Current (E2-03), and
then adjust the Slip Compensation Gain (C3-01) to between 0.5 and 1.5. The default setting for V/f control
is C3-01 = 0.0 (slip compensation disabled).
• To improve speed response and stability in V/f control with a PG (A1-02 = 1), set the ASR constants (C5-
01 to C5-05) to between 0.5 and 1.5 times the default. (It is not normally necessary to adjust this setting.)
ASR for V/f control with a PG will only control the output frequency; a high gain, such as is possible for
open-loop vector control 2 or flux vector control, cannot be set.
The following user constants will also indirectly affect the control system.
Table 4.5 Constants Indirectly Affecting Control and Applications
Name (Constant Number)
4-18
Application
Dwell function (b6-01 to b6-04)
Used for heavy loads or large machine backlashes.
Droop function (b7-01 to b7-02)
Used to soften the torque or to balance the load between two motors. Can
be used when the control mode (A1-02) is set to 3 or 4.
Acceleration/deceleration times
(C1-01 to C1-11)
Adjust torque during acceleration and deceleration.
S-curve characteristics (C2-01 to C2-04)
Used to prevent shock when completing acceleration.
Adjustment Suggestions
Table 4.5 Constants Indirectly Affecting Control and Applications(Continued)
Name (Constant Number)
Application
Jump frequencies (d3-01 to d3-04)
Used to avoid resonance points during operation.
Analog input filter time constant (H3-12)
Used to prevent fluctuations in analog input signals caused by noise.
Stall prevention (L3-01 to L3-06)
Used to prevent 0 V (overvoltage errors) and motor stalling for heavy
loads or rapid acceleration/deceleration. Stall prevention is enabled by
default and the setting does not normally need to be changed. When using
a braking resistor, however, disable stall prevention during deceleration
by setting L3-04 to 0.
Torque limits (L7-01 to L7-04)
Set the maximum torque during vector control. If a setting is increased,
use a motor with higher capacity than the Inverter. If a setting is reduced,
stalling can occur under heavy loads.
Feed forward control (N5-01 to N5-03)
Used to increase response for acceleration/deceleration or to reduce overshooting when there is low machine rigidity and the gain of the speed
controller (ASR) cannot be increased. The inertia ratio between the load
and motor and the acceleration time of the motor running alone must be
set.

Set T1-02 and T1-04 when 2 is set for T1-01. Only set value 2 is possible for V/f control or V/f control with PG.
These are values for a 200 V class Inverter. Values for a 400 V class Inverter are double.
The factory setting depends on the Inverter capacity. (The value for a 200 V Class Inverter for 0.4 kW is given.)
The setting range is from 10% to 200% of the Inverter rated output current. (The value for a 200 V Class Inverter for 0.4 kW is given.)
The upper setting limit will be 150.0 Hz when C6-01 is set to 0.

Note Attach a Momentary Power Interruption Compensation Unit if compensation for power interruptions of up to 2.0 seconds is required for 200 V class
Inverters with outputs of 0.4 to 7.5 kW.
* 1. The initial settings for C6-02 are as follows: 0: Low noise PWM, 1: 2.0 kHz, 2: 5.0 kHz, 3: 8.0 kHz, 4: 10 kHz, 5: 12.5 kHz, and 6: 15 kHz. If the carrier
frequency is set higher than the factory setting for Inverters with outputs of 5.5 kW or more, the Inverter rated current will need to be reduced.
* 2. The initial settings for C6-11 are as follows: 1: 2.0 kHz, 2: 4.0 kHz, 3: 6.0 kHz, 4: 8.0 kHz.

Switch between 2 Step Speeds: Master/Auxiliary Speeds
When switching between the master and auxiliary speeds, connect the master speed frequency reference to
control circuit terminal A1 or A2 and connect the auxiliary speed frequency reference to terminal A3. The reference on terminal A1 or A2 will be used for the Inverter frequency reference when the multi-function input
allocated to multi-speed command 1 is OFF and the reference on terminal A3 will be used when it is ON.
When switching between the master and auxiliary speeds, set H3-05 (Multi-function analog input terminal
6-3
A3) to 2 (auxiliary frequency reference, 2nd step analog) and set on of the multi-function input terminals to
multi-step speed reference 1.
When inputting a current to terminal A2 for the master speed frequency reference, set H3-08 (Multi-function
analog input terminal A2 signal level selection) to 2 (current input), and set H3-09 (Multi-function analog

Setting Precautions
When setting analog inputs to step 1 to step 3, observe the following precautions.
• When setting terminal A1's analog input to step 1, set b1-01 to 1, and when setting d1-01 (Frequency Ref-
erence 1) to step 1, set b1-01 to 0.
• When setting terminal A2's analog input to step 2, set H3-09 to 2 (auxiliary frequency reference). When
setting d1-02 (Frequency Reference 2) to step 2, set H3-09 to 1F (do not use analog inputs).
• When setting terminal A3's analog input to step 3, set H3-05 to 3 (auxiliary frequency reference 2). When
setting d1-03(Frequency Reference 3) to step 3, set H3-05 to 1F (Analog input not used).

Performing Operations Using a Digital Operator
When b1-02 is set to 0, you can perform Inverter operations using the Digital Operator keys (RUN, STOP,
JOG, and FWD/REV). For details on the Digital Operator, refer to Chapter 3 Digital Operator and Modes.
Performing Operations Using Control Circuit Terminals
When b1-02 is set to 1, you can perform Inverter operations using the control circuit terminals.
Performing Operations Using a 2-wire Sequence
The factory setting is set to a 2-wire sequence. When control circuit terminal S1 is set to ON, forward operation will be performed, and when S1 is turned OFF, the Inverter will stop. In the same way, when control circuit terminal S2 is set to ON, reverse operation will be performed, and when S2 is turned OFF, the Inverter
will stop.

Performing Operations Using a 3-wire Sequence
When any constant from H1-01 to H1-10 (multi-function contact input terminals S3 to S12) is set to 0, terminals S1 and S2 are used for a 3-wire sequence, and the multi-function input terminal that has been set functions as a forward/reverse run command terminal.
When the Inverter is initialized for 3-wire sequence control with A1-03, multi-function input 3 becomes the
input terminal for the forward/reverse run command.

Stopping Methods
Stopping Methods
This section explains methods of stopping the Inverter.
Selecting the Stopping Method when a Stop Command is Sent
There are four methods of stopping the Inverter when a stop command is sent:
• Deceleration to stop
• Coast to stop
• DC braking stop
• Coast to stop with timer
Set constant b1-03 to select the Inverter stopping method. A DC braking stop and coasting to a stop with a
timer cannot be set for flux vector control.

Deceleration to Stop
If the stop command is input (i.e., the run command is turned OFF) when b1-03 is set to 0, the motor decelerates to a stop according to the deceleration time that has been set. (Factory setting: C1-02 (Deceleration Time
1))
If the output frequency when decelerating to a stop falls below b2-01, the DC injection brake will be applied
using the DC current set in b2-02 only for the time set in b2-04.
For deceleration time settings, refer to page 6-16 Setting Acceleration and Deceleration Times.

Coast to Stop
If the stop command is input (i.e., the run command is turned OFF) when b1-03 is set to 1, the Inverter output
voltage is interrupted. The motor coasts to a stop at the deceleration rate that counterbalances damage to the
machine and inertia including the load.

INFO
DC Braking Stop
If the stop command is input (i.e., the run command is turned OFF) when b1-03 is set to 2, a wait is made for
the time set in L2-03 (Minimum Baseblock (BB) Time) and then the DC injection brake current set in b2-02 is
sent to the motor to apply a DC injection brake to stop the motor. The DC injection brake time is determined
by the set value in b2-04 and the output frequency when the stop command is input.

Inputting the DC Injection Brake Command from Control Circuit Terminals
If you set a multi-function contact input terminal (H1-) to 60 (DC injection brake command), you can
apply the DC injection brake to the motor by turning ON the terminal for which the DC injection brake command has been set when the Inverter is being stopped. DC injection braking is used at startup for flux vector
control.
The time chart for the DC injection brake is shown below.

Changing the DC Injection Brake Current Using an Analog Input
If you set H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-function
Analog Input Terminal A3 Function Selection) to 6 (DC injection brake current), you can change the DC
injection brake current level using the analog input.
At 10 V input (voltage) or 20 mA input (current), 100% of the Inverter rated current will be applied.

Using an Emergency Stop
Set a multi-function input terminal (H1-) to 15 or 17 (emergency stop) to decelerate to a stop at the deceleration time set in C1-09. If inputting the emergency stop with an NO contact, set the multi-function input terminal (H1-) to 15, and if inputting the emergency stop with an NC contact, set the multi-function input
terminal (H1-) to 17.
After the emergency stop command has been input, operation cannot be restarted until the Inverter has
stopped. To cancel the emergency stop, turn OFF the run command and emergency stop command.

Switching Acceleration and Deceleration Time Automatically
Use this setting when you want to switch acceleration/deceleration time automatically using the set frequency.
When the output frequency reaches the set value in C1-11, the Inverter switches the acceleration/deceleration
time automatically as shown in the following diagram.
Set C1-11 to a value other than 0.0 Hz. If C1-11 is set to 0.0 Hz, the function will be disabled.

When output frequency ≥ C1-11, acceleration and deceleration are performed using
Acceleration/deceleration Time 1 (C1-01, C1-02).
When output frequency < C1-11, acceleration and deceleration are performed using
Acceleration/deceleration Time 4 (C1-07, C1-08).

Adjusting Acceleration and Deceleration Time Using an Analog Input
If you set H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-function
Analog Input Terminal A3 Function Selection) to 5 (acceleration/deceleration time gain), you can adjust the
acceleration/deceleration time using terminal A2's input voltage.
The Inverter's acceleration time when the acceleration time has been set in C1-01 is as follows:
Acceleration time = C1-01 set value x acceleration/deceleration time gain
Acceleration/deceleration time gain (set value: 5)
(Acceleration/deceleration gain from 1 to
10 V) = 10 V/Input voltage (V) x 10 (%)

6-17
Entering S-curve Characteristics in the Acceleration and Deceleration Time
By performing acceleration and deceleration using an S-curve pattern, you can reduce shock when starting and
stopping the machine.
Using the Inverter, you can set an S-curve characteristic time for each of the following: Acceleration start
time, deceleration start time, acceleration end time, and deceleration end time.
INFO
Set the S-curve characteristic time to lengthen acceleration/deceleration time as follows:
Acceleration time = Selected acceleration time + (Acceleration start time S-curve characteristic time +
Acceleration end time S-curve characteristic time) / 2
Deceleration time = Selected deceleration time + (Deceleration start time S-curve characteristic time +
Deceleration end time S-curve characteristic time) / 2

Preventing the Motor from Stalling During Acceleration (Stall Prevention
During Acceleration Function)
The Stall Prevention During Acceleration function prevents the motor from stalling if a heavy load is placed
on the motor, or sudden rapid acceleration is performed.
If you set L3-01 to 1 (enabled) and the Inverter output current exceeds the -15% level of the set value in L302, the acceleration rate will begin to slow down. When L3-02 is exceeded, acceleration will stop.
If you set L3-01 to 2 (optimum adjustment), the motor current accelerates to the value set in L3-02. With this
setting, the acceleration time setting is ignored.

Setting Precautions
• If the motor capacity is small compared to the Inverter capacity, or if the motor is operated using the fac-
tory settings, resulting in the motor stalling, lower the set value of L3-02.
• If using the motor in the constant output range, L3-02 will be automatically lowered to prevent stalling.
L3-03 is the limit value to prevent the stall prevention level in the constant output range from being
reduced more than necessary.
• Set the constants as a percent taking the inverter rated voltage to be 100%.

Preventing Overvoltage During Deceleration (Stall Prevention During
Deceleration Function)
The Stall Prevention During Deceleration function makes the rate of deceleration more gentle to suppress
increases in DC bus voltage when the DC bus voltage exceeds the set value during motor deceleration.
This function automatically lengthens the deceleration time with respect to the bus voltage, even if the deceleration time has been set to a considerably small value.
If L3-04 is set to 1 or 2, when the main circuit DC voltage approaches the stall prevention level during deceleration, deceleration stops, and when deceleration falls below the level, is restarted. Using this operation,
deceleration time is automatically lengthened. If L3-04 is set to 1, deceleration time returns to the set value,
and if L3-04 is set to 2, deceleration is automatically adjusted to a faster deceleration time within the range of
the stall prevention level during deceleration.

• When using the braking option (braking resistor, Braking Resistor Units, and Braking Units), be sure to set
constant L3-04 to 0 or 3.
• To decelerate at a shorter time than the deceleration time set when L3-04 is set to 0 with the braking option
enabled, set L3-04 to 3.
• The setting of L3-04 is ignored for flux vector control or open-loop vector control 2.

Adjusting Analog Frequency Reference Using Constants
The frequency reference is input from the control circuit terminals using analog voltage and current.
If using frequency reference terminal A1 as an input terminal, perform adjustments using constants H3-02 and
H3-03. If using multi-function analog input terminal A2 as a frequency reference terminal, perform adjustments using H3-10 and H3-11.

Improved Operating Efficiency
This section explains functions for improving motor operating efficiency.
Reducing Motor Speed Fluctuation (Slip Compensation Function)
When the load is large, the amount of motor slip also grows large and the motor speed decreases. The slip
compensation function controls the motor at a constant speed, regardless of changes in load. When the motor
is operating at the rated load, constant E2-02 (Motor Rated Slip) × the frequency in constant C3-01 is added to
the output frequency.

Adjusting Slip Compensation Gain
You can switch the C3-01 constant settings as shown below by changing the control method.
• V/f control without PG: 0.0
• Open-loop vector control: 1.0
• Flux vector control: 1.0
Set C3-01 to 1.0 to compensate the rated slip set using the rated torque output status.
Adjust the slip compensation gain using the following procedure.
1. Set E2-02 (Motor Rated Slip) and E2-03 (Motor No-load Current) correctly.
You can calculate the motor rated slip from the values on the motor nameplate using the following formula.
Amount of motor rated slip (Hz) = Motor rated frequency (Hz) - No. of rated rotations (min−1.) × No. of
motor poles / 120
Set the values for rated voltage, rated frequency, and no-load current in the motor unladen current. The
motor rated slip is set automatically in the vector control using autotuning.
2. In V/f control, set C3-01 to 1.0. Setting this constant to 0.0 disables slip compensation.
3. Apply a load, and measure the speed to adjust the slip compensation gain. Adjust the slip compensation
gain by 0.1 at a time. If the speed is less than the target value, increase the slip compensation gain, and if
the speed is greater than the target value, reduce the slip compensation gain.
For flux vector control, the slip compensation gain is used as the motor temperature compensation gain. When
the motor temperate increases, the motor’s internal constant increases, resulting in an increase in slip. If C3-01
is set, the amount of slip is adjusted as the temperature rises. Set C3-01 if the amount of torque varies with the
temperature when using torque control or a torque limit. The larger the value of C3-01, the larger the compensation.
Adjusting Slip Compensation Primary Delay Time Constant
Set the slip compensation primary delay time constant in ms.
You can switch the factory settings as follows by changing the control method.
• V/f control without PG: 2000 ms
• Open-loop vector control: 200 ms
Normally, there is no need to make these settings. When the slip compensation response is low, lower the set
value. When the speed is unstable, increase the set value.
Adjusting Slip Compensation Limit
Set the upper limit for the slip compensation amount as a percent, taking the motor rated slip amount as 100%.
If the speed is lower than the target value but does not change even when you adjust the slip compensation
gain, the motor may have reached the slip compensation limit. Increase the limit, and check the speed again.
Make the settings, however, to make sure that the value of the slip compensation limit and reference frequency
does not exceed the tolerance of the machine.
The following diagram shows the slip compensation limit for the constant torque range and fixed output range.
6-33
Slip compensation limit
Output frequency
E1-06: Base frequency
E1-04: Maximum output frequency
Fig 6.31 Slip Compensation Limit
Selecting Slip Compensation Function During Regeneration
Set whether to enable or disable the slip compensation function during regeneration.
If the slip compensation function operates during regeneration, you might have to use the braking option
(braking resistor, Braking Resistor Unit, and Braking Unit) to momentarily increase the regenerative amount.
Selecting Output Voltage Limit Operation
If output voltage saturation occurs while the output voltage limit operation is disabled, the output current will
not change, but torque control accuracy will be lost. If torque control accuracy is required, change the settings
to enable the output voltage limit operation.
If the output voltage limit operation is enabled, motor magnetic flux current is controlled automatically, and
torque control accuracy is maintained to limit the output voltage references. Consequently, the output current
will increase by approximately 10% maximum (with rated load) compared with when the output voltage limit
operation is disabled, so check the Inverter current margin.
Setting Precautions
• If using the device at medium to low speed only, if the power supply voltage is 10% or more higher than
the motor rated voltage, or if the torque control accuracy at high speeds is insufficient, it is not necessary to
change the output voltage limit operation.
• If the power supply voltage is too low compared with the motor rated voltage, torque control accuracy may
be lost even if the output voltage limit operation is enabled.
Compensating for Insufficient Torque at Startup and Low-speed Operation (Torque Compensation)
The torque compensation function detects that the motor load has increased, and increases the output torque.
V/f control calculates and adjusts the motor primary loss voltage according to the output voltage (V), and
compensates for insufficient torque at startup and during low-speed operation. Calculate the compensation
voltage as follows: Motor primary voltage loss × constant C4-01.
Vector control separates the motor excitation current and the torque current by calculating the motor primary
current, and controlling each of the two separately.
Calculate the torque current as follows: Calculated torque reference × C4-01

Carrier Frequency Setting Precautions
When selecting the carrier frequency, observe the following precautions.
• Adjust the carrier frequency according to the cases shown below.
If the wiring distance between Inverter and motor is long: Set the carrier frequency low. (Use the following
values as guidelines.)

If speed and torque are inconsistent at low speeds: Set the carrier frequency low.
If leakage current from the Inverter is large: Set the carrier frequency low.
If metallic noise from the motor is large: Set the carrier frequency high.
• When using V/f control or V/f control with PG, you can vary the carrier frequency according to the output
frequency, as shown in the following diagram, by setting C6-03 (Carrier Frequency Upper Limit), C6-04
(Carrier Frequency Lower Limit), and C6-05 (Carrier Frequency Proportional Gain).

• With vector control, the carrier frequency is fixed to the Carrier Frequency Upper Limit in C6-03 if user-
set or by the carrier frequency set in C6-02.
• To fix the carrier frequency, set C6-03 and C6-04 to the same value, or set C6-05 to 0.
• If the settings are as shown below, OPE11 (Constant setting error) will occur.
If Carrier Frequency Proportional Gain (C6-05) > 6 and C6-03 < C6-04.
• Depending on the carrier frequency setting, the Inverter’s overload level may be reduced. Even when the
overload current falls to below 150%, OL2 (Inverter overload) will be detected. The Inverter overload current reduction level is shown below.

Limiting Motor Torque (Torque Limit Function)
The motor torque limit function is enabled only with open-loop torque control.
In the open-loop vector control method, the user-set value is applied to the torque limit by calculating internally the torque output by the motor. Enable this function if you do not want a torque above a specified
amount to be applied to the load, or if you do not want a regeneration value above a specified amount to occur.

Note The forward torque limit is the limit value when the analog input signal generates forward torque. This torque limit setting is enabled even when the
analog input signal generates forward torque while the motor is operating (regeneration).
Setting the Torque Limit in Constants
Using L7-01 to L7-04, you can set individually four torque limits in the following directions: Forward drive,
reverse drive, forward regeneration, and reverse regeneration.
6-41
Set the Torque Limit Value Using an Analog Input
You can change the analog input level torque limit value by setting the torque limit in multi-function analog
input terminals A2 and A3.
The analog input terminal signal level is factory-set as follows:
Multi-function analog input terminal A2: 4 to 20 mA
Multi-function analog input terminal A3: 0 to 10

Machine Protection
Setting Precautions
• When the torque limit function is operating, control and compensation of the motor speed is disabled
because torque control is given priority.
• When using the torque limit to raise and lower loads, do not carelessly lower the torque limit value, as this
may result in the motor falling or slipping.
• Torque limits using an analog input are the upper limit value (during 10 V or 20 mA input) of 100% of the
motor rated torque. To make the torque limit value during 10 V or 20 mA input 150% of the rated torque,
set the input terminal gain to 150.0 (%). Adjust the gain for multi-function analog input terminal A2 using
H3-10 and for multi-function analog input terminal A3 using H3-06.
• The torque limit accuracy is ±5% at the output frequency of 10 Hz or above. When output frequency is less
than 10 Hz, accuracy is lowered.
Preventing Motor Stalling During Operation
Stall prevention during operation prevents the motor from stalling by automatically lowering the Inverter's
output frequency when a transient overload occurs while the motor is operating at a constant speed.
Stall prevention during operation is enabled only during V/f control. If the Inverter output current continues to
exceed the setting in constant L3-06 for 100 ms or longer, the motor speed is reduced. Set whether to enable or
disable deceleration time using constant L3-05. Set the deceleration time using C1-02 (Acceleration time 1) or
C1-04 (Acceleration Time 2).
If the Inverter output current reaches the set value in L3-06 - 2% (Inverter Rated Output Current), the motor
will accelerate again at the frequency set or the acceleration time set.

Changing Stall Prevention Level during Operation Using an Analog Input
If you set H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-function
Analog Input Terminal A3 Function Selection) to 8 (stall prevention level during run), you can change the stall
level during operation by setting H3-10 (Gain (Terminal A2)) and H3-11 (Bias (Terminal A2)) or H3-06 (Gain
(Terminal A3)) and H3-07 (Bias (Terminal A3).
The stall prevention level during operation enabled is the multi-function analog input terminal A2 or A3 input
level or the set value in constant L3-06, whichever is the smaller.

If the motor capacity is smaller than the Inverter capacity or the motor stalls when operating at the factory settings, lower the stall prevention level during operation.
INFO
Detecting Motor Torque
If an excessive load is placed on the machinery (overtorque) or the load is suddenly lightened (undertorque),
you can output an alarm signal to multi-function output terminal M1-M2, M3-M4, M5-M6, P3-C3, or P4-C4.
To use the overtorque/undertorque detection function, set B, 17, 18, 19 (overtorque/undertorque detection NO/
NC) in one of the following constants: H2-01 to H2-05 (multi-function output terminals M1-M2, P1-PC, P2PC, P3-C3, and P4-C4 function selection).
The overtorque/undertorque detection level is the current level (Inverter rated output current 100%) in V/f
control, and the motor torque (motor rated torque 100%) in vector control.

Setting Precautions
• If multiple motors are connected to one Inverter, set constant L1-01 to 0 (disabled). To protect the motor,
install a thermal relay in the motor power cable, and perform overload protection on each motor.
• With applications where the power supply is often turned ON and OFF, there is a risk that the circuit cannot be protected even if this constant has been set to 1 (enabled), because the thermal value will be reset.
• To detect overloads in good time, set the set value in constant L1-02 to a low setting.
• When using a general-purpose motor (standard motor), the cooling ability will be lowered by f1/4 (fre-
quency). Consequently, the frequency may cause motor overload protection (OL1) to occur, even below
the rated current. If operating using the rated current at a low frequency, use a special motor.
6-51
Setting the Motor Overload Pre-Alarm
If the motor overload protection function is enabled (i.e., L1-01 is set to other than 0) and you set H2-01 to
H2-05 (multi-function output terminals M1-M2, M3-M4, M5-M6, P3-C3, and P4-C4 function selection) to 1F
(motor overload OL1 pre-alarm), the motor overload pre-alarm will be enabled. If the electronic thermal value
reaches minimum 90% of the overload detection level, the output terminal that has been set will be turned ON.

Continuing Operation
Continuing Operation
This section explains functions for continuing or automatically restarting Inverter operation even if an
error occurs.
Restarting Automatically After Power Is Restored
Even if a temporary power loss occurs, you can restart the Inverter automatically after power is restored to
continue motor operation.
To restart the Inverter after power is restored, set L2-01 to 1 or 2.
If L2-01 is set to 1, when power is restored within the time set in L2-02, the Inverter will restart. If the time set
in L2-02 is exceeded, alarm UV1 (main circuit undervoltage) will be detected.
If L2-01 is set to 2, when the main power supply is restored while the control power supply (i.e., power supply
to the control panel) is backed up, the Inverter will restart. Consequently, alarm UV1 (main circuit undervoltage) will not be detected.

* 2. These values are for a 200 V Class Inverter. For a 400 V Class Inverter, double the values.
Setting Precautions
• Error output signals are not output during momentary power loss recovery.
• To continue Inverter operation after power has been restored, make settings so that run commands from the
control main circuit terminal are stored even while power is suspended.
• If the momentary power loss operation selection is set to 0 (Disabled), when the momentary power loss
exceeds 15 ms during operation, alarm UV1 (main circuit undervoltage) will be detected.
Speed Search
The speed search function finds the actual speed of the motor that is rotating using inertia, and then starts
smoothly from that speed. When restoring power after a temporary power loss, the speed search function
switches connection from the commercial power supply, and then restarts the fan that is rotating using inertia.

Setting Precautions
• When both external search commands 1 and 2 are set for the multi-function contact terminals, an OPE03
(invalid multi-function input selection) operation error may occur. Set either external search command 1 or
external search command 2.
• If speed search during startup is selected when using V/f control with PG, the Unit will start from the fre-
quency detected by PG.
• If performing speed search using external search commands, add an external sequence so that the period
when the run command and external search command are both ON is at the very least the Minimum Baseblock Time (L2-03).
• If the Inverter output is equipped with a contact, set the contact operation delay time in the Speed Search
Wait Time (b3-05). The factory setting is 0.2 s. When not using the contact, you can reduce the search time
by making the setting 0.0 s. After waiting for the speed search wait time, the Inverter starts the speed
search.
• Constant b3-02 is a current detection speed search (current detection level for search completion). When
the current falls below the detection level, the speed search is viewed as completed, and the motor accelerates or decelerates to the set frequency. If the motor cannot restart, lower the set value.
• If an overcurrent (OC) is detected when using speed search after recovery following a power loss, lengthen
the Minimum Baseblock Time (L2-03).
Application Precautions for Speed Searches Using Estimated Speed
• When using V/f control with or without a PG, always perform stationary autotuning for only line-to-line
resistance before using speed searches based on estimated speeds.
• When using open-loop vector control, always perform rotational autotuning before using speed searches
based on estimated speeds.
• If the cable length between the motor and Inverter is changed after autotuning has been performed, per-
form stationary autotuning for only line-to-line resistance again.
The motor will not operate when stationary autotuning or stationary autotuning only for line-to-line
resistance is performed.

Input Terminal Functions
This section explains input terminal functions, which set operating methods by switching functions for the
multi-function contact input terminals (S3 to S12).
Temporarily Switching Operation between Digital Operator and Control
Circuit Terminals
You can switch the Inverter run command inputs and frequency reference inputs between local (i.e., Digital
Operator) and remote (input method using b1-01 and b1-02).
You can switch between local and remote by turning ON and OFF the terminals if an output from H1-01 to
H1-10 (multi-function contact input terminal S3 to S12 function selection) has been set to 1 (local/remote
selection).
To set the control circuit terminals to remote, set b1-01 and b1-02 to 1 (Control circuit terminals).

Stopping Acceleration and Deceleration (Acceleration/Deceleration
Ramp Hold)
The acceleration/deceleration ramp hold function stops acceleration and deceleration, stores the output frequency at that point in time, and then continues operation.
Set one of the constants H1-01 to H1-10 (multi-function contact input terminal S3 to S12 function selection)
to A (acceleration/deceleration ramp hold) to stop acceleration and deceleration when the terminal is turned
ON and to store the output frequency at that point in time. Acceleration and deceleration will restart when the
terminal is turned OFF.
If d4-01 is set to 1 and the Acceleration/Deceleration Ramp Hold command is input, the output frequency is
still stored even after the power supply is turned OFF.

Application Precautions
• When d4-01 is set to 1, the output frequency on hold is stored even after the power supply is turned OFF. If
performing operations using this frequency after the Inverter has also been turned OFF, input the run command with the Acceleration/Deceleration Ramp Hold turned ON.
• When d4-01 is set to 0 and a run command is input while the Acceleration/Deceleration Ramp Hold is
turned ON, the output frequency will be set to zero.
• If you input an Acceleration/Deceleration Ramp Hold command by error when decelerating during posi-
tioning, deceleration may be canceled.
Raising and Lowering Frequency References Using Contact Signals (UP/
DOWN)
The UP and DOWN commands raise and lower Inverter frequency references by turning ON and OFF a multifunction contact input terminal S3 to S7.
To use this function, set one of the constants H1-01 to H1-10 (multi-function contact input terminal S3 to S12
function selection) to 10 (UP command) and 11 (DOWN command). Be sure to allocate two terminals so that
the UP and DOWN commands can be used as a pair.
The output frequency depends on the acceleration and deceleration time. Be sure to set b1-02 (Run command
selection) to 1 (Control circuit terminal).

Precautions
When setting and using UP and DOWN commands, observe the following precautions.
Setting Precautions
If multi-function input terminals S3 to S12 are set as follows, operation error OPE03 (Invalid multi-function
input selection) will occur:
• Only either the UP command or DOWN command has been set.
6-69
• UP/DOWN commands and Acceleration/Deceleration Ramp Hold have been allocated at the same time.
Application Precautions
• Frequency outputs using UP/DOWN commands are limited by the frequency reference upper and lower
limits set in constants d2-01 to d2-03. Here, frequency references from analog frequency reference terminal A1 becomes the frequency reference lower limit. If using a combination of the frequency reference
from terminal A1 and the frequency reference lower limit set in either constant d2-02 or d2-03, the larger
lower limit will become the frequency reference lower limit.
• If inputting the run command when using UP/DOWN commands, the output frequency accelerates to the
frequency reference lower limit.
• When using UP/DOWN commands, multi-step operations are disabled.
• When d4-01 (Frequency Reference Hold Function Selection) is set to 1, the frequency reference held using
the UP/DOWN functions is stored even after the power supply is turned OFF. When the power supply is
turned ON and the run command is input, the motor accelerates to the frequency reference that has been
stored. To reset (i.e., to 0 Hz) the stored frequency reference, turn ON the UP or DOWN command while
the run command is ON.

Hold Analog Frequency Using User-set Timing
When one of H1-01 to H1-10 (multi-function contact input terminal S3 to S12 function selection) is set to 1E
(sample/hold analog frequency command), the analog frequency reference will be held from 100 ms after the
terminal is turned ON, and operation will continue thereafter at that frequency.
The analog value 100 ms after the command is turned ON is used as the frequency reference.

Precautions
When setting and executing sample and hold for analog frequency references, observe the following precautions.
Setting Precautions
When using sample/hold of analog frequency reference, you cannot use the following commands at the same
time. If these commands are used at the same time, operation error OPE03 (invalid multi-function input selection) will occur.
• Acceleration/Deceleration Ramp Hold command
• UP/DOWN command
• Trim Control Increase/Decrease command
Application Precautions
• When performing sample/hold of analog frequency references, be sure to store references of 100 ms mini-
mum. If the reference time is less than 100 ms, the frequency reference will not be held.
• The analog frequency reference that is held will be deleted when the power supply is turned OFF.
Switching Operations between a Communications Option Card and Control Circuit Terminals
You can switch reference input between the Communications Option Card and the control circuit terminals.
Set one of the constants H1-01 to H1-10 (multi-function contact input terminal S3 to S12 function selection)
to 2 (Option/Inverter selection) to enable switching reference input using the terminal ON/OFF status when
the Inverter is stopped.
6-73
Setting Precautions
To switch command inputs between the Communications Option Card and the control circuit terminals, set the
following constants.
• Set b1-01 (Reference Selection) to 1 (Control circuit terminal [analog input])
• Set b1-02 (Operation Method Selection to 1 (Control circuit terminal (sequence inputs])
• Set one of the constants H1-01 to H1-10 (multi-function contact input terminal S3 to S12 function selec-
tion) to 2 (Option/Inverter selection).

Input Terminal Functions
Stopping the Inverter by Notifying Programming Device Errors to the
Inverter (External Fault Function)
The external fault function performs the error contact output, and stops the Inverter operation if the Inverter
peripheral devices break down or an error occurs. The digital operator will display EFx (External fault [input
terminal Sx]). The x in EFx shows the terminal number of the terminal that input the external fault signal. For
example, if an external fault signal is input to terminal S3, EF3 will be displayed.
To use the external fault function, set one of the values 20 to 2F in one of the constants H1-01 to H1-10 (multifunction contact input terminal S3 to S12 function selection).
Select the value to be set in H1-01 to H1-10 from a combination of any of the following three conditions.
• Signal input level from peripheral devices
• External fault detection method
• Operation during external fault detection

Using MEMOBUS Communications
You can perform serial communications with MEMOCON-series Programmable Controllers (PLCs) or similar devices using the MEMOBUS protocol.
MEMOBUS Communications Configuration
MEMOBUS communications are configured using 1 master (PLC) and a maximum of 31 slaves. Serial communications between master and slave are normally started by the master, and the slave responds.
The master performs signal communications with one slave at a time. Consequently, you must set the address
of each slave beforehand, so the master can perform signal communications using that address. Slaves receiving commands from the master perform the specified function, and send a response to the master.

IMPORTANT
1. Separate the communications cables from the main circuit cables and other wiring and power cables.
2. Use shielded cables for the communications cables, connect the shield cover to the Inverter earth terminal,
and arrange the terminals so that the other end is not connected to prevent operating errors due to noise.
3. When using RS-485 communications, connect S+ to R+, and S- to R-, on the Inverter exterior.

Procedure for Communicating with the PLC
Use the following procedure to perform communications with the PLC.
1. Turn OFF the power supply turned and connect the communications cable between the PLC and the
Inverter.
2. Turn ON the power supply.
3. Set the required communications constants (H5-01 to H5-07) using the Digital Operator.
4. Turn OFF the power supply, and check that the Digital Operator display has completely disappeared.
5. Turn ON the power supply once again.
6. Perform communications with the PLC.
Set the timer on the master to monitor response time from the slave. Set the master so that if the slave does
not respond to the master within the set time, the same command message will be sent from the master
again.

MEMOBUS communications can perform the following operations regardless of the settings in b1-01 and b102.
• Monitoring operation status from the PLC
• Setting and reading constants
• Resetting errors
• Inputting multi-function commands
An OR operation is performed between the multi-function commands input from the PLC and commands
input from multi-function contact input terminals S3 to S7.
Message Format
In MEMOBUS communications, the master sends commands to the slave, and the slave responds. The message format is configured for both sending and receiving as shown below, and the length of data packets is
changed by the command (function) contents.

Error Check
Errors are detected during communications using CRC-16. Perform calculations using the following method.
1. The factory setting for CRC-16 communications is usually 0, but when using the MEMOBUS system, set
the factory setting to 1 (i.e., set all 16 bits to 1).
2. Calculate CRC-16 using MSB as slave address LSB, and LSB as the MSB of the final data.
3. Also calculate CRC-16 for response messages from the slaves, and compare them to the CRC-16 in the
response messages.
MEMOBUS Message Example
An example of MEMOBUS command/response messages is given below.
Reading Storage Register Contents
Read the contents of the storage register only for specified quantities whose addresses are consecutive, starting
from a specified address. The contents of the storage register are separated into higher place 8 bits and lower
place 8 bits, and comprise the data within response messages in address order.
The following table shows message examples when reading status signals, error details, data link status, and

ENTER Command
When writing constants to the Inverter from the PLC using MEMOBUS communications, the constants are
temporarily stored in the constant data area in the Inverter. To enable these constants in the constant data area,
use the ENTER command.
There are two types of ENTER commands: ENTER commands that enable constant data in RAM, and
ENTER commands that write data to EEPROM (non-volatile memory) in the Inverter at the same time as
enabling data in RAM.
The following table shows the ENTER command data. ENTER command data can only be written.
The ENTER command is enabled by writing 0 to register number 0900H or 0910H.
Register No.

INFO
6-90
Contents
The maximum number of times you can write to EEPROM using the Inverter is 100 thousand. Do not frequently execute ENTER commands (0900H) written to EEPROM.
The ENTER command registers are write-only. Consequently, if reading these registers, the register address
will become invalid (Error code: 02H).
Individual Functions
Error Codes
The following table shows MEMOBUS communications error codes.
Error Code
Contents
01H
Function code error
A function code other than 03H, 08H, or 10H has been set by the PLC.
02H
Invalid register number error
• The register address you are attempting to access is not recorded anywhere.
• With broadcast sending, a start address other than 0000H, 0001H, or 0002H has been set.
03H
Invalid quantity error
• The number of data packets being read or written is outside the range 1 to 16.
• In write mode, the number of data packets in the message is not No. of packets x 2.
21H
Data setting error
• A simple upper limit or lower limit error has occurred in the control data or when writing constants.
• When writing constants, the constant setting is invalid.
22H
Write mode error
• Attempting to write constants from the PLC during operation.
• Attempting to write via ENTER commands from the PLC during operation.
• Attempting to write constants other than A1-00 to A1-05, E1-03, or 02-04 when warning alarm
CPF03 (defective EEPROM) has occurred.
• Attempting to write read-only data.
23H
Writing during main circuit undervoltage (UV) error
• Writing constants from the PLC during UV (main circuit undervoltage) alarm.
• Writing via ENTER commands from the PLC during UV (main circuit undervoltage) alarm.
24H
Writing error during constants processing
Attempting to write constants from the PLC while processing constants in the Inverter.
Slave Not Responding
In the following cases, the slave will ignore the write function. If the slave address specified in the command
message is 0, all slaves execute the write function, but do not return response messages to the master.
• When a communications error (overrun, framing, parity, or CRC-16) is detected in the command message.
• When the slave address in the command message and the slave address in the Inverter do not agree.
• When the data that configures the message and the data time length exceeds 24 bits.
• When the command message data length is invalid.
Application Precautions
Set a timer in the master to monitor response time from the slaves. Make the setting so that if no response is
sent to the master from the slave within the set time, the same command message is sent again from the master.
6-91
Self-Diagnosis
The Inverter has a built-in function for self-diagnosing the operations of serial communications interface circuits. This function is called the self-diagnosis function. The self-diagnosis function connects the communications parts of the send and receive terminals, receives the data sent by the Inverter, and checks if
communications are being performed normally.
Perform the self-diagnosis function using the following procedure.
1. Turn ON the power supply to the Inverter, and set 67 (communications test mode) in constant H1-05 (Terminal S7 Function Selection).
2. Turn OFF the power supply to the Inverter.
3. Perform wiring according to the following diagram while the power supply is turned OFF.
4. Turn ON the terminating resistance. (Turn ON pin 1 on DIP switch 1.)
5. Turn ON the power supply to the Inverter again.

Individual Functions
Using the Timer Function
Multi-function contact input terminals S3 to S7 can be designated as timer function input terminals, and multifunction output terminals M1-M2, M3-M4, and M5-M6 can be designated as timer function output terminals.
By setting the delay time, you can erase chattering from the sensors and switches.
• Set one of the constants H1-01 to H1-10 (multi-function contact input terminal S3 to S12) to 18 (timer
function input).
• Set H2-01 to H2-03 (multi-function output terminals M1-M2, M3-M4, M5-M6, P3-C3, and P4-C4 func-
tion selection) to 12 (timer function output).

Using PID Control
PID control is a method of making the feedback value (detection value) match the set target value. By combining proportional control (P), integral control (I), and derivative control (D), you can even control targets
(machinery) with play time.
The characteristics of the PID control operations are given below.
P control
Outputs the amount of operation proportional to the deviation. You cannot, however, set the
deviation to zero using P control alone.
I control
Outputs the amount of operation that integrates the deviation. Used for matching feedback

D control
Outputs the amount of operation derived from the deviation. Can respond promptly to rapid
variations.
PID Control Operation
To understand the differences between each PID control operation (P, I, and D, the variation in the amount of
operation (output frequency) is as shown in the following diagram when the deviation (i.e., the difference
between the target value and feedback value) is fixed.

Setting Precautions
• In PID control, the b5-04 constant is used to prevent the calculated integral control value from exceeding a
specified amount. When the load varies rapidly, Inverter response is delayed, and the machine may be
damaged or the motor may stall. In this case, reduce the set value to speed up Inverter response.
• The b5-06 constant is used to prevent the arithmetic operation following the PID control calculation from
exceeding a specified amount. Set taking the maximum output frequency to be 100%.
• The b5-07 constant is used to adjust PID control offset. Set in increments of 0.1%, taking the maximum
output frequency to be 100%.
• Set the low pass filter time constant for the PID control output in b5-08. Enable this constant to prevent
machinery resonance from occurring when machinery adhesive abrasion is great, or rigidity is poor. In this
case, set the constant to be greater than the resonance frequency cycle. Increase this time constant to
reduce Inverter responsiveness.
• Using b5-09, you can invert the PID output polarity. Consequently, if you increase the PID target value,
you can apply this constant to applications to lower the Inverter output frequency.
• Using b5-10, you can apply gain to the PID control output. Enable this constant to adjust the amount of
compensation if adding PID control output to the frequency reference as compensation.
• When PID control output is negative, you can use constant b5-11 to invert the Inverter. When b1-04 (Pro-
hibition of Reverse Operation) is set to 1 (enabled), however, PID output limit is 0.
• With the Inverter, by setting an independent acceleration/deceleration time in constant b5-17, you can
increase or decrease the PID target value using the acceleration/deceleration time. The acceleration/
deceleration function (constant C1) used normally, however, is allocated after PID control, so depending
on the settings, resonance with PID control and hunting in the machinery may occur. If this happens,
reduce constant C1 until hunting does not occur, and maintain the acceleration/deceleration time using b517. Also, you can disable the set value in b5-17 from the external terminals during operation using multifunction input set value 34 (PID soft starter).

PID Feedback Loss Detection
When performing PID control, be sure to use the PID feedback loss detection function. If PID feedback is lost,
the Inverter output frequency may accelerate to the maximum output frequency.
When setting b5-12 to 1 and the status of the PID feedback value detection level in b5-13 is insufficient and
continues for the time set in b5-14, an FbL (PID feedback reference lost) alarm will be displayed on the Digital Operator and Inverter operation will continue.
When b5-12 is set to 2, an FbL (PID feedback reference lost) error alarm will be displayed on the Digital
Operator, the error contact will operate, and Inverter operation will be stopped.
The time chart for PID feedback loss detection (set b5-12 to 2) is shown below.

PID Sleep
The PID sleep function stops the Inverter when the PID sleep function delay time continues while the PID
control target value is at an insufficient level to operate the PID sleep function. When the PID sleep delay time
continues and the PID control target value is above the PID sleep function operation level, Inverter operation
will automatically resume.
When PID control is disabled, the PID sleep function is also disabled. When using the PID sleep function,
select decelerate to stop or coast to stop as the stopping method.

Adjusting Energy-saving Control
The method of adjustment during energy-saving control operations differs depending on the control method.
Refer to the following when making adjustments.
V/f Control
In V/f control method, the voltage for optimum motor efficiency is calculated and becomes the output voltage
reference.
• b8-04 (Energy-saving Coefficient) is set at the factory for motor use applied to the Inverter. If the motor
capacity differs from the motor applied to the Inverter, set the motor capacity in E2-11 (Motor Rated Output). Also, adjust the output voltage in steps of 5 until it reaches minimum. The larger the energy-saving
coefficient, the greater the output voltage.
• To improve response when the load fluctuates, reduce the power detection filter time constant b8-05. If b8-
05 is set too small, however, motor rotations when the load is light may become unstable.
• Motor efficiency varies due to temperature fluctuations and differences in motor characteristics. Conse-
quently, control motor efficiency online to optimize efficiency by causing minute variations in voltage
using the search operation. Constant b8-06 (Search Operation Voltage Limiter) controls the range that control the voltage using the search operation. For 200 V Class Inverters, set the range to 100%/200 V, and for
400 V Class Inverters, set the range to 100%/400 V. Set to 0 to disable the search operation.
Vector Control
In vector control method, control the slip frequency so that motor efficiency is maximized.
• Taking the motor rated slip for the base frequency as optimum slip, calculate the optimum slip for motor
efficiency for each frequency. In vector control, be sure to perform autotuning, and set the motor rated slip.
• If the motor performs hunting when using energy-saving control in vector control, reduce the set value in
b8-02 (Energy-saving Gain), or increase the set value in b8-03 (Energy-saving Filter Time Constant).

Manual Motor Constant Setting Methods
The motor constants settings methods are given below. Make (enter) settings referring to the motor test report.
Motor Rated Voltage Setting
Set E2-01 to the rated current on the motor nameplate.
Motor Rated Slip Setting
Set E2-02 to the motor rated slip calculated from the number of rated rotations on the motor nameplate.
Amount of motor rated slip = Motor rated frequency (Hz) - No. of rated rotations (min−1) x No. of motor
poles/120.
Motor No-Load Current Setting
Set E2-03 to the motor no-load current using the rated voltage and rated frequency. The motor no-load current
is not normally written on the motor nameplate. Consult the motor manufacturer.
Factory setting is the no-load current value for a standard Yaskawa 4-pole motor.
Number of Motor Poles Setting
E2-04 is displayed only when V/f control method with PG is selected. Set the number of motor poles (number
of poles) as written on the motor nameplate.
Motor Line-to-Line Resistance Setting
E2-05 is set automatically when performing motor line-to-line resistance autotuning. When you cannot perform tuning, consult the motor manufacturer for the line-to-line resistance value. Calculate the resistance from the line-to-line resistance value in the motor test report using the following formula, and then make the setting accordingly.
• E-type isolation: [Line-to line resistance (Ω) at 75°C of test report] × 0.92 (Ω)
• B-type isolation: [Line-to line resistance (Ω) at 75°C of test report] × 0.92 (Ω)
• F-type isolation: [Line-to line resistance (Ω) at 115°C of test report] × 0.87 (Ω)
Motor Leak Inductance Setting
Set the amount of voltage drop due to motor leak inductance in E2-06 using the percentage over the motor
rated voltage. Make this setting when the high-speed motor inductance is small. If the inductance is not written on the motor nameplate, consult the motor manufacturer.
Motor Iron Saturation Coefficients 1 and 2 Settings
E2-07 and E2-08 are set automatically using autotuning.
Motor Iron Loss for Torque Compensation Setting
E2-10 is displayed only when in V/f control method. To increase the torque compensation accuracy when in
V/f control method, set the motor iron loss in Watts.
Motor Mechanical Loss
When using flux vector control, adjust mechanical loss in the following cases. (There is normally no reason to
make this adjustment.) The mechanical loss setting is used to compensate the torque.
• There is excessive torque loss from the motor bearings.
• There is excessive torque loss from a fan, pump, etc.

These are values for a 200 V Class Inverter. Values for a 400 V Class Inverter are double.
The factory setting will change when the control method is changed. (Open-loop vector control factory settings are given.)
The contents of constants E1-11 and E1-12 are ignored when set to 0.00.
E1-13 is set to the same value as E1-05 by autotuning.
The setting range is 0 to 66.0 for open-loop vector control 2.
Setting Inverter Input Voltage
Set the Inverter input voltage correctly in E1-01 to match the power supply voltage. This set value will be the
standard value for the protection function and similar functions.
Setting V/f Pattern
Set the V/f pattern in E1-03 when using V/f control (with or without a PG). There are two methods of setting
the V/f pattern: Select one of the 15 pattern types (set value: 0 to E) that have been set beforehand, or set a
user-defined V/f pattern (set value: F).
The factory setting for E1-03 is F. The contents of E1-03 when factory-set to F are the same as when E1-03 is
set to 1.
To select one of the existing patterns, refer to the following table.

The input can be used for torque compensation by setting H3-05 to 14.
The direction of the torque output from the motor will be determined by the sign of the analog signal input. It
does not depend on the direction of the run command. The direction of torque will be as follows:
• Positive analog reference: Torque reference for forward motor rotation (counterclockwise as viewed from
the motor output axis).
• Negative analog reference: Torque reference for reverse motor rotation (clockwise as viewed from the
motor output axis).
Application Precautions
If the analog signal input level is 0 to 10 V or 4 to 20 mA, a forward torque reference will not be applied. To
apply reverse torque, use an input level of -10 V to 10 V or switch the direction using a multi-function input
set to 78 (polarity reverse command for external torque reference).

Individual Functions
The direction in which speed is controlled is determined by the sign of the speed limit signal and the direction
of the run command.
• Positive voltage applied: The speed in the forward direction will be limited for forward operation.
IMPORTANT
• Negative voltage applied: The speed in the reverse direction will be limited for reverse operation.
If the direction of motor rotation and the command direction are not the same, speed will be limited to 0 as
long as b5-05 is set to 0.
Speed Limit Bias Setting
The speed limit bias can be set to limit both the forward and reverse speed to the same value. This differs from
the operation of the speed limit setting. To use the speed limit bias, set d5-04 to 0 and set the bias in d5-05 as a
percentage of the maximum output frequency.
To set 50% forward and reverse speed limits, set the speed limit setting to 0 (d5-03 = 2, d5-04 = 0, and d5-05
= 50). The range of torque control will be from -50% to 50% of the maximum output speed.
When using both the speed limit and the speed limit bias, the range of torque control will be positive and negative speed limits with the speed limit bias added to each.
The range of torque control when the forward speed limit is 50% and the speed limit bias is 10% is shown in
the following figure. This figure does not take the priority circuit into account.

Torque Limit Operation Examples
Operation examples will be described separately for winding operation, in which the speed and motor torque
are in the same directions, and rewinding operation, in which the speed and motor torque are in opposite directions.
Winding Operation
In a winding operation, the line (speed) and torque generated by the motor are in the same direction. For the
winding operation, both the speed limit and the torque reference input are positive. The motor will accelerate
when the torque reference input is larger than the load and will decelerate when it is smaller than the load. If
the motor turns faster than the speed limit, a negative compensation value is output from the speed limiter circuit. When the speed then drops below the speed limit, a positive compensation value is output. The torque
compensation is proportional to the ASR proportional gain. When the sum of the torque reference and the
torque compensation output by the speed limiter is the same as the actual load, the motor will stop accelerating
and run at a constant speed.
6-119
Rewinding Operation
In a rewinding operation, the line (speed) and torque generated by the motor are in the opposite directions. (In
this example, we’ll assume that the line speed is positive and the torque reference input is negative.) For the
rewinding operation, the speed limit is positive and the torque reference input is negative. If the motor turns
faster than the speed limit, a negative compensation value is output from the speed limiter circuit. If the motor
is rotating in reverse, a negative compensation value is output. If the speed is 0 or is below the speed limit, a 0
compensation value is output. In this way, the output from the speed limiter is used to maintain the motor
speed between 0 and the speed limit. When the sum of the torque reference and the torque compensation output by the speed limiter is the same as the actual load, the motor will stop accelerating and run at a constant
speed.

Torque Reference Adjustment
Consider the following information when adjusting the torque.
Torque Reference Delay Time: d5-02
The time constant of the primary filter in the torque reference section can be adjusted. This constant is used to
eliminate noise in the torque reference signal and adjust the responsiveness to the host controller. Increase the
setting if oscillation occurs during torque control.
Setting the Torque Compensation
Set multi-function analog input A2 or A3 to torque compensation (setting 14). When the amount of torque loss
for mechanical loss or other factor at the load is input to one of these terminals, it is added to the torque reference to compensate for the loss. The direction of torque will be as follows:
• Positive voltage (current): Torque compensation reference for forward motor rotation (counterclockwise as
viewed from the motor output axis).
6-120
Individual Functions
• Negative voltage: Torque compensation reference for reverse motor rotation (clockwise as viewed from
the motor output axis).
Since the polarity of the voltage input determines the direction, only forward torque compensation can be
input when the 0 to 10 V or 4 to 20 mA signal level has been selected. If you want to input reverse torque compensation, be sure to select the 0 to ±10 V signal level.
Speed/Torque Control Switching Function
It is possible to switch between speed control and torque control when one of the multi-function inputs (H1-01
to H1-10) is set to 71 (Speed/Torque Control Change). Speed control is performed when the input is OFF and
torque control is performed when the input is ON. Set d5-01 to switch speed/torque control.
Setting the Speed/Torque Control Switching Timer
The delay between a change in the speed/control switching function input (ON to OFF or OFF to ON) and the
corresponding change in the control mode can be set in d5-06. During the timer delay, the value of the 3 analog inputs will retain the values they had when the ON/OFF status of speed/torque control switching signal
was changed. Use this delay to complete any changes required in external signals.
Application Precautions
• The frequency reference (during speed control) is set in b1-01. The speed limit during torque control is set
in d5-03.
• If the torque reference has been assigned to a multi-function analog input, terminal A2, or terminal A3, the
input function changes when the control mode is switched between torque control and speed control.
During speed control: The analog input terminal is used as the torque limit input.
During torque control: The analog input terminal is used as the torque reference input.
• When the run command turns OFF, the control method when stopped will be for speed control. Even from
the torque control mode, the system will automatically change to speed control and decelerate to a stop
when the run command turns OFF.
• When A1-02 (control method selection) is set to 3 (flux vector control), the speed/torque change command
(a setting of 71) can be set for a multi-function input (H1-01 to H1-10) to switch between speed and torque
control during operation. An example is shown below.

Speed Control (ASR) Structure
Speed control (ASR) during vector control adjusts the torque reference so that the deviation between the
speed reference and the estimated speed (PG feedback or speed estimator) is 0. Speed control (ASR) during V/
f control with a PG adjusts the output frequency so that the deviation between the speed reference and the estimated speed (PG feedback or speed estimator) is 0. The following block diagram shows the structure of the
speed control for vector or V/f control with a PG.

At zero-speed, decrease C5-02
(ASR I Time 1) until there is no oscillation.

operates at the maximum normal operating
speed?
YES

to monitor the output frequency.
Settings that allow multi-function analog output 2 to be used
to monitor the motor speed.
Settings that allow a 0 to ±10 V
signal range to be monitored.
The multi-function analog outputs have the following functions with these constant settings.
• Multi-function analog output 1 (terminal FM): Outputs Inverter's output frequency (0 to ±10 V).
• Multi-function analog output 2 (terminal AM): Outputs actual motor speed (0 to ±10 V).
6-124
Individual Functions
Terminal AC is the multi-function analog output common.
We recommend monitoring both the output frequency and the motor speed to monitor the response delay or
deviations from the reference value, as shown in the following diagram.
Adjusting ASR Proportional Gain 1 (C5-01)
This gain setting adjusts the responsiveness of the speed control (ASR). The responsiveness is increased when
this setting is increased. Usually this setting is higher for larger loads. Oscillation will occur if this setting is
increased too much.
The following diagram shows the type of changes that can occur in the response when the ASR proportional
gain is changed.
Motor speed
The proportional gain is high.
(Oscillation occurs when the gain is too high.)
The proportional gain is low.
Time
Fig 6.68 Responsiveness for Proportional Gain
Adjusting ASR Integral Time 1 (C5-02)
This constant sets the speed control (ASR) integral time.
Lengthening the integral time lowers the responsiveness, and weakens the resistance to external influences.
Oscillation will occur if this setting is too short. The following diagram shows the type of changes that can
occur in the response when the ASR integral time is changed.

Different Gain Settings for Low-speed and High-speed
Switch between low-speed and high-speed gain when oscillation occurs because of resonance with the
mechanical system at low speed or high speed. The proportional gain P and integral time I can be switched
according to the motor speed, as shown below.

Setting the Gain Switching Frequency (C5-07)
Set the switching frequency to about 80% of the motor operating frequency or the frequency at which oscillation occurs.
Low-speed Gain Adjustments (C5-03, C5-04)
Connect the actual load and adjust these constants at zero-speed. Increase C5-03 (ASR proportional gain 2)
until there is no oscillation. Decrease C5-04 (ASR integral time 2) until there is no oscillation.
High-speed Gain Adjustments (C5-01, C5-02)
Adjust these constants at normal operating speed. Increase C5-01 (ASR proportional gain 1) until there is no
oscillation. Decrease C5-02 (ASR integral time 1) until there is no oscillation. Refer to Fine Adjustments on
page 6 - 124 for details on making fine adjustments of high-speed operation.
ASR Proportional Gain Switch Setting
When one of the multi-function inputs (H1-01 to H1-10) is set to 77, the input can be used to switch between
C5-01 (proportional gain 1) and C5-03 (proportional gain 2). Proportional gain 2 is used when the multi-function input is ON. This input has higher priority than the ASR switching frequency set in C5-07.

Gain Adjustment for Speed Control during V/f Control with PG
When using V/f control with PG, set the proportional gain (P) and the integral time (I) at E1-09 (minimum output frequency) and E1-04 (maximum output frequency). Fig 6.72 Speed Control Gain Integral Time Adjustment for V/f Control with PG shows how the proportional gain and integral time change in linear fashion based
on the speed.

Gain Adjustments at Minimum Output Frequency
Operate the motor at the minimum output frequency. Increase C5-03 (ASR proportional gain 2) to a level
where there is no oscillation. Decrease C5-04 (ASR integral time 2) to a level where there is no oscillation.
Monitor the Inverter's output current and verify that it is less than 50% of the Inverter rated current. If the output current exceeds 50% of the Inverter's rated current, decrease C5-03 and increase C5-04.
Gain Adjustments at Maximum Output Frequency
Operate the motor at the maximum output frequency. Increase C5-01 (ASR proportional gain 1) to a level
where there is no oscillation. Decrease C5-02 (ASR integral time 1) to a level where there is no oscillation.
Fine Adjustments
When you want even finer gain adjustment, adjust the gain while observing the speed waveform. The adjustment method is the same as that for vector control.
Enable integral operation during acceleration and deceleration (by setting F1-07 to 1) when you want the
motor speed to closely follow the frequency reference during acceleration and deceleration. Reduce the setting
of C5-01 if overshooting occurs during acceleration, and reduce the setting of C5-03 and increase the setting
of C5-04 if undershooting occurs when stopping. If overshooting and undershooting cannot be eliminated by
adjusting only the gain, reduce the value of C5-05 speed control and reduce the limit of the frequency reference compensation value.
Droop Control Function
Droop control is a function that allows the user to set the amount of motor slip.
When a single load is operated with two motors (such as in a crane conveyor), a high-resistance motor is normally used. This is to use torque characteristics that exhibit proportion movements due to changes in the secondary resistor to maintain torque balance with the load and overall speed balance with the load.
If droop control is used, a high-resistance motor characteristics can be set for a general-purpose motor.

Zero-servo Function
The zero-servo function holds the motor when the motor is stopped in what is call a zero-servo status. This
function can be used to stop the motor even with an external force acts on the motor or the analog reference
input is offset.

Individual Functions
The zero-servo function is enabled when one of the multi-function inputs (H1-01 to H1-10) is set to 72 (zero

• Be sure to leave the run command input ON. If the run command is turned OFF, the output will be inter-
rupted and the zero-servo function will become ineffective.
6-130
Individual Functions
• The holding force of the zero-servo is adjusted in b9-01. The holding force will increase if the value of the
setting is increased, but oscillation and hunting will occur if the setting is too large. Adjust b9-01 after
adjusting the speed control gain.
• The zero-servo detection width is set as the allowable position offset from the zero-servo start position. Set
4 times the number of pulses from the PG.
• The Zero Servo End signal will go OFF when the zero servo command is turned OFF.
Do not lock the servo for extended periods of time at 100% when using the zero servo function. Inverter
errors may result. Extended periods of servo lock can be achieved by ensuring that the current during the servolock is 50% or less or by increasing the Inverter capacity.

Changing Frequency Reference and Display Units
Set the Digital Operator frequency reference and display units using constant o1-03. You can change the units
for the following constants using o1-03.
• U1-01 (Frequency Reference)
• U1-02 (Output Frequency)
• U1-05 (Motor Speed)
• U1-20 (Output Frequency after Soft Start)
• d1-01 to d1-17 (Frequency references)
Switching Monitors when the Power Supply Is ON
Using constant o1-02, select the monitor item (U1- [status monitor]) to be displayed on the Digital Operator when the power supply is turned ON. For monitors that can be displayed, refer to U1- in Chapter 5
User Constants.
6-133
Setting Precautions
If selecting monitor constants other than U1-01 (Frequency Reference), U1-02 (Output Frequency), and U103 (Output Current), first select the monitor items to be displayed in o1-01, and then set o1-02 to 4.
Disabling the STOP Key
If b1-02 (Operation Method Selection) is set to 1, 2, or 3, the stop command from the STOP Key on the Digital
Operator is an emergency stop command.
Set o2-02 to 0 to disable emergency stop commands from the STOP Key on the Digital Operator.
Disabling the LOCAL/REMOTE Key
Set o2-01 to 0 to disable the LOCAL/REMOTE Key on the Digital Operator. You cannot switch Inverter reference inputs set using reference inputs from the Digital Operator, b1-01 (Reference Selection), or b1-02
(Operation Method Selection).
Initializing Changed Constant Values
You can save to the Inverter constant set values that you have changed as constant initial values. Change the
set values from the Inverter factory settings, and then set o2-03 to 1.
Set A1-03 (Initialize) to 1110 to initialize the Inverter constants using the user-set initial values in memory. To
clear the user-set initial values in memory, set o2-03 to 2.
Setting the Frequency Reference using the UP and DOWN Keys without Using the
Enter Key
Use this function when inputting frequency references from the Digital Operator. When o2-05 is set to 1, you
can increment and decrement the frequency reference using the UP and DOWN Keys without using the Enter
Key.
For example, enter the Run command using a 0 Hz reference, and then continuously press the UP Key to
increment the frequency reference by 0.01 Hz only for the first 0.5 s, and then by 0.01 Hz every 80 ms for 3 s
thereafter. Press and hold down the UP Key for 3 s minimum to reach the maximum output frequency 10 s
after that. The frequency reference that has been set will be stored in memory 5 s after the UP or DOWN Keys
are released.
Clearing Cumulative Operation Time
Set the cumulative operation time initial value in time units in constant o2-07. Set o2-07 to 0 to clear U1-13
(inverter Operating Time).
Clearing Inverter Cooling Fan Operation Time
Set the fan operation time initial value in time units in constant o2-10. Set o2-10 to 0 to clear U1-40 (Cooling
Fan Operating Time).

Digital Operator Functions
Copying Constants
The Digital Operator can perform the following three functions using the built-in EEPROM (non-volatile
memory).
• Store Inverter constant set values in the Digital Operator (READ)
• Write constant set values stored in the Digital Operator to the Inverter (COPY)
• Compare constant set values stored in the Digital Operator with Inverter constants (VERIFY)

the Digital Operator.
If you set one of the constants H1-01 to H1-05 (multi-function contact input terminal S3 to S7 function selection) to 1B (write constants permitted), you can write constants from the digital operator when the terminal
that has been set is ON. When the set terminal is OFF, writing constants other than the frequency reference is
prohibited. You can, however, reference constants.

Using PG Speed Control Card
There are four types of PG Speed Control Card that can be used in V/f control with PG.
• PG-A2: A-phase (single) pulse input, compatible with open collector or complimentary outputs.
• PG-B2: A/B-phase pulse input, compatible with complimentary outputs.
• PG-D2: A-phase (single) pulse input, compatible with line drivers.
• PG-X2: A/B/Z-phase pulse input, compatible with line drivers.
There are two types of PG Speed Control Cards that can be used for flux vector control.
• PG-B2: A/B phase pulse inputs, complementary outputs
• PG-X2: A/B/Z phase pulse inputs, line driver outputs
For the connection diagram, refer to page 2-32.
Setting Number of PG Pulses
Set the number of PG (Pulse Generator/Encoder) pulses in pulses/rotation. Set the number of A-phase or Bphase pulses per 1 motor rotation in F1-01.
Matching PG Rotation Direction and Motor Rotation Direction
Constant F1-05 matches the PG rotation direction and the motor rotation direction. If the motor is rotating forwards, set whether it is A-phase driven or B-phase driven. Make this setting when using PG-B2 or PG-X2.

Yaskawa standard PG used is A-phase driven (CCW) when motor rotation is forward.
Fig 6.75 PG Rotation Direction Setting
Generally, PG is A-phase driven when rotation is clockwise (CW) see from the input axis. Also, motor rotation is counter-clockwise (CCW) seen from the output side when forward commands are output. Consequently, when motor rotation is forward, PG is normally A-phase driven when a load is applied, and B-phase
driven when a load is not applied.

Options
Setting Number of Gear Teeth Between PG and Motor
Set the number of PG gear teeth in F1-12 and F1-13. If there are gears between the motor and PG, you can
operate the motor by setting the number of gear teeth.
When the number of gear teeth has been set, the number of motor rotations within the Inverter is calculated
using the following formula.
No. of motor rotations (min−1.) = No. of input pulses from PC × 60 / F1-01 × F1-13 (No. of gear teeth on load
side) / F1-12 (No. of gear teeth on motor side)
Matching Motor Speed During Acceleration and Deceleration to Frequency Reference
You can select whether to enable or disable integral operation during acceleration and deceleration when using
flux vector control.
To match the motor speed as closely as possible to the frequency reference even during acceleration and deceleration, set F1-07 to 1.
If F1-01 is set to 1, overshoot or undershoot may occur easily immediately after acceleration and deceleration. To minimize the possibility of overshoot or undershoot occurring, set F1-01 to 0.
IMPORTANT
Setting PG Pulse Monitor Output Dividing Ratio
This function is enabled only when using PG speed control card PG-B2. Set the dividing ratio for the PG pulse
monitor output. The set value is expressed as n for the higher place digit, and m for the lower place 2 digits.
The dividing ratio is calculated as follows:
Dividing ratio = (1 + n)/m (Setting range) n: 0 or 1, m: 1 to 32
F1-06 =
n
m
The dividing ratio can be set within the following range: 1/32 ≤ F1-06 ≤ 1. For example, if the dividing ratio is
1/2 (set value 2), half of the number of pulses from the PG are monitor outputs.
Detecting PG Open Circuit
Select the stopping method when PG cable disconnected is detected and the PG open circuit (PGO) detection
time.
When the Inverter is operating with the frequency reference set to 1% minimum (except when operating on
direct current), if the speed feedback from PG is greater than the time setting in F1-14, PGO is detected.
Detecting Motor Overspeed
An error is detected when the number of motor rotations exceeds the regulated limit. An overspeed (OS) is
detected when a frequency that exceeds the set value in F1-08 continues for longer than the time set in F1-09.
After detecting an overspeed (OS), the Inverter stops according to the setting in F1-03.
Detecting Speed Difference between the Motor and Speed Reference
An error is detected when the speed deviation (i.e., the difference between the designated speed and the actual
motor speed) is too great. Speed deviation (DEV) is detected after a speed agreement is detected and when the
speed reference and actual workpiece speed are within the setting of L4-02, if a speed deviation great than the
set value in F1-10 continues for longer than the time set in F1-11. After a speed deviation is detected, the
Inverter stops according to the setting in F1-04.

Using an Analog Reference Card
When using a AI-14B or A1-14U Analog Reference Card, set constant b1-01 (Reference selection) to 3
(Option Card).
AI-14B provides 3 channels of bi-polar inputs with 14-bit A/D conversion accuracy (and a sign bit). The function of each channel is determined by the setting of F2-01.
AI-14U provides 2 channels of bi-polar inputs with 14-bit A/D conversion accuracy. Channel 1 is a voltage
input and channel 2 is a current input. The sum of channels 1 and 2 is a frequency input. F2-01 does not need
to be set for the AI-14U.

Application Precautions
• The maximum frequency (100% speed) reference will be used when the binary input is set (setting: 6 or 7)
and all bits are 1.
• Setting F3-01 to 6 is valid only when the D1-16H2 is used. Using this setting, a frequency from 0.00 to
399.8 Hz can be set in BCD. The sign bit is used as a data bit, so only positive (plus) data can be set. Also,
the digit starts from 0, so the minimum setting is 0.02 Hz.

Protective and Diagnostic Functions
This section describes the alarm functions of the Inverter. The alarm functions include fault detection,
alarm detection, operation error detection, and autotuning error detection.
Fault Detection
When the Inverter detects a fault, the fault contact output operates, and the Inverter output is shut OFF causing
the motor to coast to a stop. (The stopping method can be selected for some faults, and the selected stopping
method will be used with these faults.) A fault code is displayed on the Digital Operator.
When a fault has occurred, refer to the following table to identify and correct the cause of the fault.
Use one of the following methods to reset the fault after restarting the Inverter:
• Set a multi-function contact input (H1-01 to H1-05) to 14 (Fault Reset) and turn ON the fault reset signal.
• Press the RESET Key on the Digital Operator.
• Turn the main circuit power supply OFF and then ON again.

Troubleshooting
Troubleshooting
Due to constant setting errors, faulty wiring, and so on, the Inverter and motor may not operate as
expected when the system is started up. If that should occur, use this section as a reference and apply the
appropriate measures.
If the contents of the fault are displayed, refer to Protective and Diagnostic Functions.
If Constant Constants Cannot Be Set
Use the following information if an Inverter constant cannot be set.
The display does not change when the Increment and Decrement Keys are pressed.
The following causes are possible.
The Inverter is operating (drive mode).
There are some constants that cannot be set during operation. Turn the Inverter off and then make the settings.
Constant write enable is input.
This occurs when “constant write enable” (set value: 1B) is set for a multi-function input terminal (H1-01 to
H1-10). If the constant write enable input is OFF, the constants cannot be changed. Turn it ON and then set the
constants.
Passwords do not match. (Only when a password is set.)
If the constant A1-04 (Password) and A1-05 (Password Setting) numbers are different, the constants for the
initialize mode cannot be changed. Reset the password.
If you cannot remember the password, display A1-05 (Password Setting) by pressing the Reset/Select Key and
the Menu Key simultaneously while in the A1-04 display. Then reset the password. (Input the reset password
in constant A1-04.)
OPE01 through OPE11 is displayed.
The set value for the constant is wrong. Refer to Operation Errors in this chapter and correct the setting.
CPF00 or CPF01 is displayed.
This is a Digital Operator communications error. The connection between the Digital Operator and the
Inverter may be faulty. Remove the Digital Operator and then re-install it.
7-17
If the Motor Does Not Operate
Use the following information if the motor does not operate.
The motor does not operate when the RUN Key on the Digital Operator is pressed.
The following causes are possible.
If the Inverter is not in drive mode, it will remain in ready status and will not start. Press the Menu Key to display the drive mode, and enter the drive mode by pressing the DATA/ENTER Key. “-Rdy-” will be displayed
when drive mode is entered.
IMPORTANT
The operation method setting is wrong.
If constant b1-02 (Operation Method Selection) is set to 1 (control circuit terminal), the motor will not operate
when the Run Key is pressed. Either press the LOCAL/REMOTE Key* to switch to Digital Operator operation or set b1-02 to 0 (Digital Operator).
The LOCAL/REMOTE Key is enabled by setting o2-01 to 1 and disabled by setting o2-01 to 2. It is enabled
when the drive mode is entered.
INFO
The frequency reference is too low.
If the frequency reference is set below the frequency set in E1-09 (Minimum Output Frequency), the Inverter
will not operate.
Raise the frequency reference to at least the minimum output frequency.
There is a multi-function analog input setting error.
If multi-function analog input H3-09 is set to 1 (frequency gain), and if no voltage (current) is input, then the
frequency reference will be zero. Check to be sure that the set value and analog input value are correct.
The motor does not operate when an external operation signal is input.
The following causes are possible.
The Inverter is not in drive mode.
If the Inverter is not in drive mode, it will remain in ready status and will not start. Press the MENU Key to
display the drive mode, and enter the drive mode by pressing the DATA/ENTER Key. “-Rdy-” will be displayed when drive mode is entered.
7-18
Troubleshooting
The operation method selection is wrong.
If constant b1-02 (reference selection) is set to 0 (Digital Operator), the motor will not operate when an external operation signal is input. Set b1-02 to 1 (control circuit terminal) and try again.
Similarly, the motor will also not operate if the LOCAL/REMOTE Key has been pressed to switch to Digital
Operator operation. In that case press the LOCAL/REMOTE Key* again to return to the original setting.
The LOCAL/REMOTE Key is enabled by setting o2-01 to 1 and disabled by setting o2-01 to 2. It is enabled
when the drive mode is entered.
INFO
A 3-wire sequence is in effect.
The input method for a 3-wire sequence is different than when operating by forward/stop and reverse/stop (2wire sequence). When 3-wire sequence is set, the motor will not operate even when an input terminal suitable
for forward run/stop and reverse run/stop is turned ON.
When using a 3-wire sequence, refer to the timing chart and input the proper signals.
When using a 2-wire sequence, set the multi-function input terminal (H1-01 through H1-10, terminals S3 to
S11) to a value other than 0.
The frequency reference is too low.
If the frequency reference is set below the frequency set in E1-09 (Minimum Output Frequency), the Inverter
will not operate. Raise the frequency reference to at least the minimum output frequency.
There is a multi-function analog input setting error.
If multi-function analog inputs H3-05 (Multi-function Analog Input Terminal A3 Selection) and H3-09
(Multi-function Analog Input Terminal A2 Selection) are set to 1 (frequency gain), and if no voltage (current)
is input, then the frequency reference will be zero. Check to be sure that the set value and analog input value
are correct.
The motor stops during acceleration or when a load is connected.
The load may be too heavy. The Inverter has a stall prevention function and an automatic torque boost function, but the motor responsiveness limit may be exceeded if acceleration is too rapid or if the load is too heavy.
Lengthen the acceleration time or reduce the load. Also consider increasing the motor capacity.
The motor only rotates in one direction.
“Reverse run prohibited” is selected. If b1-04 (Prohibition of Reverse Operation) is set to 1 (reverse run prohibited), the Inverter will not receive reverse run commands. To use both forward and reverse operation, set
b1-04 to 0.
If the Direction of the Motor Rotation is Reversed
If the motor operates in the wrong direction, the motor output wiring is faulty. When the Inverter T1(U),
T2(V), and T3(W) are properly connected to the motor T1(U), T2(V), and T3(W), the motor operates in a forward direction when a forward run command is executed. The forward direction depends on the manufacturer
and the motor type, so be sure to check the specifications.
The direction of rotation can be reversed by switching two wires among U, V, and W.
7-19
If the Motor Does Not Put Out Torque or If Acceleration is Slow
Use the following information is the motor does not output torque or if acceleration is too slow.
The torque limit has been reached.
When a torque limit has been set in constants L7-01 to L7-04, no torque will be output beyond that limit. This
can cause the torque to be insufficient, or the acceleration time to be too long. Check to be sure that the value
set for the torque limit is suitable.
If torque limits have been set for the multi-function analog input (H3-05 or H3-09 = 10 to 12 or 15), check to
be sure that the analog input value is suitable.
The stall prevention level during acceleration is too low.
If the value set for L3-02 (Stall Prevention Level during Acceleration) is too low, the acceleration time will be
too long. Check to be sure that the set value is suitable.
The stall prevention level during running is too low.
If the value set for L3-06 (Stall Prevention Level during Running) is too low, the speed will drop before outputting torque. Check to be sure that the set value is suitable.
Autotuning has not been performed for vector control
Vector control will not be perform if autotuning has not been performed. Perform autotuning separately for the
motor, or set the motor constants through calculations. Alternatively, change the Control Method Selection
(A1-02) to V/f control (0 or 1).
If the Motor Operates Higher Than the Reference
Use the following information if the motor operates higher than the reference.
The analog frequency reference bias setting is wrong (the gain setting is wrong).
The frequency reference bias set in constant H3-03 is added to the frequency reference. Check to be sure that
the set value is suitable.
A signal is being input to the frequency reference (current) terminal A1.
When 1F (frequency reference) is set for constant H3-09 (Multi-function Analog Input Terminal A2 Function
Selection), a frequency corresponding to the terminal A2 input voltage (current) is added to the frequency reference. Check to be sure that the set value and analog input value are suitable.
If the Slip Compensation Function Has Low Speed Precision
If speed control accuracy is low for the slip compensation function, the slip compensation limit has been
reached. With the slip compensation function, compensation cannot be carried out beyond the slip compensation limit set in constant C3-03. Check to be sure that the set value is suitable.
7-20
Troubleshooting
If There is Low Speed Control Accuracy at High-speed Rotation in Openloop Vector Control Mode
The motor's rated voltage is high.
The Inverter's maximum output voltage is determined by its input voltage. (For example, if 200 VAC is input,
then the maximum output voltage will be 200 VAC.) If, as a result of vector control, the output voltage reference value exceeds the Inverter output voltage maximum value, the speed control accuracy will decrease. Use
a motor with a low rated voltage (i.e., a special motor for use with vector control), or change to flux vector
control.
If Motor Deceleration is Slow
Use the following information when the motor deceleration is slow.
The deceleration time is long even when braking resistor is connected.
The following causes are possible.
“Stall prevention during deceleration enabled” is set.
When braking resistor is connected, set constant L3-04 (Stall Prevention Selection during Deceleration) to 0
(disabled) or 3 (with braking resistor). When this constant is set to 1 (enabled, the factory setting), braking
resistor does not fully function.
The deceleration time setting is too long.
Check the deceleration time setting (constants C1-02, C1-04, C1-06, and C1-08).
Motor torque is insufficient.
If the constants are correct and there is no overvoltage fault, then the motor's power is limited. Consider
increasing the motor capacity.
The torque limit has been reached.
When a torque limit has been set in constants L7-01 to L7-04, no torque will be output beyond that limit. This
can cause the deceleration time to be too long. Check to be sure that the value set for the torque limit is suitable.
If torque limits have been set for the multi-function analog input terminal A2 Function H3-09 (set value: 10 to
12 or 15), check to be sure that the analog input value is suitable.
If the Vertical-axis Load Drops When Brake is Applied
The sequence is incorrect. The Inverter goes into DC injection braking status for 0.5 seconds after deceleration
is completed. (This is the factory-set default.)
To ensure that the brake holds, set frequency detection 2 (H2-01 = 5) for the multi-function contact output terminals (M1 and Mw) so that the contacts will turn OFF when the output frequency is greater than L4-01 (3.0
to 5.0 Hz). (The contacts will turn ON below L4-01.)
There is hysteresis in frequency detection 2 (i.e., a frequency detection width, L4-02 = 2.0 Hz). Change the
setting to approximately 0.5 Hz if there are drops during stop. Do not use the multi-function contact output run
signal (H2-01 = 0) for the brake ON/OFF signal.
7-21
If the Motor Overheats
Take the following steps if the motor overheats.
The load is too big.
If the motor load is too heavy and the motor is used with the effective torque exceeding the motor's rated
torque, the motor will overheat. Some motor rating are given for short period performance and are not continuous ratings. Reduce the load amount by either lightening the load or lengthening the acceleration/deceleration time. Also consider increasing the motor capacity.
The ambient temperature is too high.
The motor rating is determined within a particular ambient operating temperature range. The motor will burn
out if it is run continuously at the rated torque in an environment in which the maximum ambient operating
temperature is exceeded. Lower the motor's ambient temperature to within the acceptable ambient operating
temperature range.
The withstand voltage between the motor phases is insufficient.
When the motor is connected to the Inverter output, a surge is generated between the Inverter switching and
the motor coil. Normally the maximum surge voltage is three times the Inverter's input power supply voltage
(i.e., 1,200 V for 400 V class). Be sure to use a motor with a withstand voltage between the motor phases that
is greater than the maximum surge voltage. In particular, when using a 400 V class Inverter, use a special
motor for Inverters.
Autotuning has not been performed for vector control
Vector control will not perform if autotuning has not been performed. Perform autotuning, or set the motor
constants through calculations. Alternatively, change the Control Method Selection (A1-02) to V/f control (0
or 1).
If There is Noise When the Inverter is Started or From an AM Radio
If noise is generated by Inverter switching, implement the following countermeasures:
• Change the Inverter's Carrier Frequency Selection (C6-02) to lower the carrier frequency. This will help to
some extent by reducing the amount of internal switching.
• Install an Input Noise Filter at the Inverter's power supply input area.
• Install an Output Noise Filter at the Inverter's power supply output area.
• Use metal tubing. Electric waves can be shielded by metal, so encase the Inverter with metal (steel).
• Ground the Inverter and motor.
• Separate main circuit wiring from control wiring.
7-22
Troubleshooting
If the Ground Fault Interrupter Operates When the Inverter is Run
The Inverter performs internal switching, so there is a certain amount of leakage current. This may cause the
ground fault interrupter to operate and cut off the power supply. Change to a ground fault interrupter with a
high leakage detection level (i.e., a sensitivity current of 200 mA or greater per Unit, with an operating time of
0.1 s or more), or one that incorporates high frequency countermeasures (i.e., one designed for use with Inverters). It will also help to some extent to change the Inverter's Carrier Frequency Selection (C6-02) to lower the
carrier frequency. In addition, remember that the leakage current increases as the cable is lengthened.
If There is Mechanical Oscillation
Use the following information when there is mechanical oscillation.
The machinery is making unusual sounds.
The following causes are possible.
There may be resonance between the mechanical system's characteristic frequency and the
carrier frequency.
If the motor is running with no problems and the machinery is oscillating with a high-pitched whine, it may
indicate that this is occurring. To prevent this type of resonance, adjust the carrier frequency with constants
C6-02 to C6-05.
There may be resonance between a machine's characteristic frequency and the output frequency of the Inverter.
To prevent this from occurring, either use the jump frequency functions in constants d3-01 to d3-04 or install
rubber padding on the motor base to reduce oscillation.
Oscillation and hunting are occurring with open-loop vector control 1.
The gain adjustment may be insufficient. Reset the gain to a more effective level by adjusting constants C4-02
(torque compensation time constant), C2-01 (S-curve Characteristic Time at Acceleration Start), and C3-02
(Slip Compensation Primary Delay Time) in order. Lower the gain setting and raise the primary delay time
setting.
Vector control will not perform if autotuning has not been performed. Perform autotuning separately for the
motor, or set the motor constants through calculations. Alternatively, change the control method selection (A102) to V/f control (0 or 1).
Oscillation and hunting are occurring with V/f control.
The gain adjustment may be insufficient. Reset the gain to a more effective level by adjusting constants C4-02
(Torque Compensation Primary Delay Time Constant), N1-02 (Hunting Prevention Gain), and C3-02 (Slip
Compensation Primary Delay Time) in order. Lower the gain setting and raise the primary delay time setting.
Oscillation and hunting are occurring with V/f w/PG control.
The gain adjustment may be insufficient. Adjust the various types of speed control loop (ASR) gain.
If the oscillation cannot be eliminated in this way, set the hunting prevention selection (constant N1-01) to 0
(disabled) and then try adjusting the gain again.
7-23
Oscillation and hunting are occurring with flux vector control.
The gain adjustment is insufficient. Adjust the various gains for speed control (ASR). If the oscillation points
overlap with those of the machine and cannot be eliminated, increase the primary delay time constant for
speed control (ASR) in C5-06 and then readjust the gains.
If autotuning is not performed, proper performance cannot be achieved for vector control. Perform autotuning
or set the motor constants according to calculations.
Oscillation and hunting are occurring with PID control.
If there is oscillation or hunting during PID control, check the oscillation cycle and individually adjust P, I,
and D constants. (Refer to page 6-97.)
Autotuning has not been performed with vector control.
Vector control will not perform if autotuning has not been performed. Perform autotuning separately for the
motor, or set the motor constants through calculations. Alternatively, change the Control Method Selection
(A1-02) to V/f control.
If the Motor Rotates Even When Inverter Output is Stopped
If the motor rotates even when the Inverter output is stopped, the DC injection braking is insufficient. If the
motor continues operating at low speed, without completely stopping, and after a deceleration stop has been
executed, it means that the DC injection braking is not decelerating enough. Adjust the DC injection braking
as follows:
• Increase the constant b2-02 (DC Injection Braking Current) setting.
• Increase the constant b2-04 (DC Injection Braking (initial excitation) Time at Stop) setting.
If 0 V is Detected When the Fan is Started, or Fan Stalls
Generation of 0 V (main circuit voltage) and stalling can occur if the fan is turning when it is started. The DC
injection braking is insufficient when starting.
This can be prevented by slowing fan rotation by DC injection braking before starting the fan. Increase the
constant b2-03 (DC injection braking time (initial excitation) at start) setting.
If Output Frequency Does Not Rise to Frequency Reference
Use the following information if the output frequency does not rise to the frequency reference.
The frequency reference is within the jump frequency range.
When the jump frequency function is used, the output frequency does not change within the jump frequency
range. Check to be sure that the Jump Frequency (constants d3-01 to d3-03) and Jump Frequency Width (constant d3-04) settings are suitable.
7-24
Troubleshooting
The frequency reference upper limit has been reached.
The output frequency upper limit is determined by the following formula:
Maximum Output Frequency (E1-04) × Frequency Reference Upper Limit (d2-01) / 100
Check to be sure that the constant E1-04 and d2-01 settings are suitable.

Application Function Precautions
Observe the following precautions when using the application functions.
• Perform rotational autotuning during trial operation whenever it is possible to separate the motor and
machine. To achieve the characteristics of vector control described in Table 10.1, the control must be
adjusted within a range that the machine will not vibrate after rotational autotuning has been performed.
• With vector control, the motor and Inverter must be connected 1:1. Vector control is not possible when
multiple motors are connected to a single Inverter. Select an Inverter capacity so the rated motor current is
50% to 100% of the rated Inverter current.
• For estimated speed searching, the motor and Inverter must be connected 1:1. The speed search must be
performed at a frequency of 130 Hz or less and with a motor with the same number of frames as or one
frame less than the Inverter capacity.
• During high-slip braking, motor loss increases, so use a high-slip braking frequency of 5% ED or less, and
a braking time of 90 seconds or less. Once high-slip braking has started, the motor cannot be restarted until
it has stopped.
• Feed forward control is a function that improves the proportional gain of the motor speed in relation to the
change in the speed reference. Adjust the response to interference loads using the speed controller (ASR)
constants.
• The torque limit function will not operate during acceleration or deceleration (during soft start transition)
when using a control mode such as open-loop vector control 1. Even if the motor speed drops due to torque
limiting while set to a fixed speed, the speed will not fall below the minimum frequency and the motor will
not slip into reverse rotation. These conditions also apply to open-loop vector control 2 and other application functions.
Precautions When Using Open-loop Vector Control 2
Using open-loop vector control 2 (A1-02=4) gives a higher level of control than conventional open-loop vector control (A1-02=2). When using open-loop vector control 2, pay attention to the points listed below. For a
comparison with other control modes, refer to Table 10.1 Overview and Features of Control Modes.
General Precautions
• The maximum possible setting for the maximum output frequency (E1-04) is 60 Hz.
• Be sure to perform autotuning. Refer to the precautions given under Autotuning in Chapter 4 Trial Opera-
tion.
Precaution on Regeneration
With speed control, in the low speed range (approx. 6 Hz max.), the speed increases for large regenerative
loads, and it may not be possible to maintain speed accuracy. Examples are given below for forward rotation at frequencies of 0.3, 1, 3, 6, and 60 Hz.

Precautions on Setting Constants
If the constants are not set properly, performance may be adversely affected.
• If there is a possibility of starting with the motor already rotating, enable the speed search function (b3-
01=1).
• When lowering a torque limit (L7-
), set it to as high a value as possible within the range allowed by
the system.
• If torque limit acceleration is performed, or if the motor slips at the torque limit causing a CF (control
fault), increase N4-08 (proportional gain of speed estimator) in steps of 5 until acceleration and deceleration are performed smoothly. When N4-08 is increased, the torque reference (U1-09) may oscillate. If so,
increase C5-06 (ASR primary delay time) by about 0.050 s.
Precaution on Torque Accuracy
To ensure torque accuracy within the speed control range of 1:10 when the motor is operated by itself at
the minimum frequency and the torque reference (U1-09) is higher than in the medium- and high-speed
ranges, increase the setting of the torque adjustment gain (N4-17) and adjust the torque reference so that it
is about the same as that in the medium and high speed ranges.
Control Modes and Applications
Application examples for the Inverter control modes are provided here.
V/f Control without PG (A1-02 = 0)

Inverter Application Precautions
Inverter Application Precautions
This section provides precautions for selecting, installing, setting, and handling Inverters.
Selection
Observe the following precautions in selecting an Inverter.
Installing Reactors
A large peak current will flow in the power input circuit when the Inverter is connected to a large-capacity
power transformer (600 kVA or higher) or when switching a phase capacitor. Excessive peak current can
destroy the convertor section. To prevent this, install a DC or AC reactor (optional) to improve the power supply power factor.
DC reactors are built into 200 V class Inverters of 18.5 to 110 kW and 400 V class Inverters of 18.5 to 300 kW.
If a thyristor convertor, such as a DC drive, is connected in the same power supply system, connect a DC or
AC reactor regardless of the power supply conditions shown in the following diagram.
Power supply

DC or AC reactor
Required
DC or AC reactor
Not required
Inverter capacity (kVA)
Fig 10.5
Inverter Capacity
When connecting special motors or multiple motors in parallel to an Inverter, select the Inverter capacity so
that the rated output current of the Inverter is 1.1 times the sum of all the motor rated currents.
Initial Torque
The startup and acceleration characteristics of the motor are restricted by the overload current ratings of the
Inverter that is driving the motor. The torque characteristics are generally less than those required when starting using a normal commercial power supply. If a large initial torque is required, select an Inverter with a
somewhat larger capacity or increase the capacity of both the motor and the inverter.
Emergency Stop
Although the Inverter's protective functions will stop operation when a fault occurs, the motor will not stop
immediately. Always provide mechanical stop and protection mechanisms on equipment requiring an emergency stop.
Options
Terminals B1, B2, , 1, 2, 3 are for connecting only the options specifically provided by Yaskawa.
Never connect any other devices to these terminals.
10-7
Installation
Observe the following precautions when installing an Inverter.
Installation in Enclosures
Either install the Inverter in a clean location not subject to oil mist, airborne matter, dust, and other contaminants, or install the Inverter in a completely enclosed panel. Provide cooling measures and sufficient panel
space so that the temperature surrounding the Inverter does not go beyond the allowable temperature. Do not
install the Inverter on wood or other combustible materials.
Installation Direction
Mount the Inverter vertically to a wall or other horizontal surface.
Settings
Observe the following precautions when making settings for an Inverter.
Upper Limits
The Digital Operator can be used to set high-speed operation up to a maximum of 400 Hz (depends on the carrier frequency). Incorrect settings can be dangerous. Use the maximum frequency setting functions to set
upper limits. (The maximum output frequency is factory-set to 60 Hz.)
DC Injection Braking
The motor can overheat if the DC injection braking voltage or braking time is set to a large value.
Acceleration/Deceleration Times
The motor's acceleration and deceleration times are determined by the torque generated by the motor, the load
torque, and the load's inertial moment (GD2/4). If the stall prevention functions are activated during acceleration or deceleration, increase the acceleration or deceleration time. The stall prevention functions will increase
the acceleration or deceleration time by the amount of time the stall prevention function is active.
To reduce the acceleration or deceleration times, increase the capacity of the motor and Inverter.
10-8
Inverter Application Precautions
Handling
Observe the following precautions when wiring or performing maintenance for an Inverter.
Wiring Check
The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W.
Check wring for any mistakes before supplying power. Check all wiring and sequences carefully.
Magnetic Contactor Installation
Do not start and stop operation frequently with a magnetic contactor installed on the power supply line. Doing
so can cause the Inverter to malfunction. Do not turn the Inverter ON and OFF with a magnetic contactor more
than one time every 30 minutes.
Maintenance and Inspections
After turn OFF the main circuit power supply, always confirm that the CHARGE indicator is not lit before
performing maintenance or inspections. The voltage remaining in the capacitor may cause electric shock.
10-9
Motor Application Precautions
This section provides precautions for motor application.
Using the Inverter for an Existing Standard Motor
When a standard motor is operated with the Inverter, power loss is slightly higher than when operated with a
commercial power supply. Observe the following precautions when using an Inverter for an existing standard
motor.
Low Speed Ranges
Cooling effects diminish in the low-speed range, resulting in an increase in the motor temperature. Therefore,
the motor torque should be reduced in the low-speed range whenever using a motor not made by Yaskawa. If
100% torque is required continuously at low speed, consider using a special inverter or vector motor.
Installation Withstand Voltage
If the input voltage is high (440 V or higher) or the wiring distance is long, the motor insulation voltage must
be considered. Contact your Yaskawa representative for details.
High-speed Operation
When using the motor at a high speed (60 Hz or more), problems may arise in dynamic balance and bearing
durability. Contact your Yaskawa representative for details.
Torque Characteristics
The motor may require more acceleration torque when the motor is operated with the Inverter than when operated with a commercial power supply. Check the load torque characteristics of the machine to be used with the
motor to set a proper V/f pattern.
Vibration
The Inverter uses a high carrier PWM to reduce motor vibration. (A constant can be set to select low carrier,
PWM modulation control as well.) When the motor is operated with the Inverter, motor vibration is almost the
same as when operated with a commercial power supply.
Motor vibration may, however, become greater in the following cases.
Resonance with the Natural Frequency of the Mechanical System
Take special care when a machine that has been operated at a constant speed is to be operated in variable speed
mode. If resonance occurs, install vibration-proof rubber on the motor base or use the frequency jump function
to skip any frequency resonating the machine.
Imbalanced Rotor
Take special care when the motor is operated at a higher speed (60 Hz or more).
Noise
Noise varies with the carrier frequency. At high carrier frequencies, the noise is almost the same when the
motor is operated with a commercial power supply. Motor noise, however, becomes louder when the motor is
operated at a speed higher than the rated speed (60 Hz).
10-10
Motor Application Precautions
Using the Inverter for Special Motors
Observe the following precautions when using a special motor.
Pole-changing Motor
The rated input current of pole-changing motors differs from that of standard motors. Select, therefore, an
appropriate Inverter according to the maximum input current of the motor to be used. Before changing the
number of poles, always make sure that the motor has stopped. Otherwise, the overvoltage protective or overcurrent protective mechanism will be actuated, resulting in an error.
Submersible Motor
The rated input current of submersible motors is higher than that of standard motors. Therefore, always select
an Inverter by checking its rated output current. When the distance between the motor and Inverter is long, use
a cable thick enough to connect the motor and Inverter to prevent motor torque reduction.
Explosion-proof Motor
When an explosion-proof motor is to be used, it must be subject to an explosion-proof test in conjunction with
the Inverter. This is also applicable when an existing explosion-proof motor is to be operated with the Inverter.
Since the Inverter itself is, however, not explosion-proof, always install it in a safe place.
Gearmotor
The speed range for continuous operation differs according to the lubrication method and motor manufacturer.
In particular, continuous operation of an oil-lubricated motor in the low speed range may result in burning. If
the motor is to be operated at a speed higher than 60 Hz, consult with the manufacturer.
Synchronous Motor
A synchronous motor is not suitable for Inverter control. If a group of synchronous motors is individually
turned ON and OFF, synchronism may be lost.
Single-phase Motor
Do not use an Inverter for a single-phase motor. The motor should be replaced with a 3-phase motor.
Power Transmission Mechanism (Speed Reducers, Belts, and Chains)
If an oil-lubricated gearbox or speed reducer is used in the power transmission mechanism, oil lubrication will
be affected when the motor operates only in the low speed range. The power transmission mechanism will
make noise and experience problems with service life and durability if the motor is operated at a speed higher
than 60 Hz.
10-11
Conformance to CE Markings
Points regarding conformance to CE markings are given below.
CE Markings
CE markings indicate conformance to safety and environmental standards that apply to business transactions
(including production, imports, and sales) in Europe. There are unified European standards for mechanical
products (Machine Directive), electrical products (Low Voltage Directive), and electrical noise (EMC Directive). CE markings are required for business transactions in Europe (including production, imports, and sales).
The Varispeed G7-Series Inverters bear CE markings indicating conformance to the Low Voltage Directive
and the EMC Directive.
• Low Voltage Directive: 73/23/EEC
93/68/EEC
• EMC Directive:
89/336/EEC
92/31/EEC
93/68/EEC
Machinery and installations that incorporate the Inverter are also subject to CE markings. It is ultimately the
responsibility of customers making products incorporating the Inverter to attach CE markings to the finished
products. The customer must confirm that the finished products (machines or installations) conform to the
European Standards.
Requirements for Conformance to CE Markings
Low Voltage Directive
Varispeed G7-Series Inverters satisfy testing for conformance to the Low Voltage Directive under the conditions described in European Standard EN50178.
Requirements for Conformance to the Low Voltage Directive
Varispeed G7-Series Inverters must satisfy the following conditions in order to conform to the Low Voltage
Directive.
• It must be used under conditions corresponding to overvoltage category 3 or less and pollution degree 2 or
less as specified in IEC664.
• Input fuses:
For details on selecting fuses, refer to Table 10.2 Selection Requirements for Input Fuses with Examples.
• With Inverters CIMR-G7C2018 to 2110 and CIMR-G7C4018 to 4300, an enclosure preventing foreign
matter from entering from the top or front sides is required (IP4X or higher: panel installation).

1. Not initialized. (Japanese standard specifications: A1-01 = 1, A1-02 = 2)
2. The factory setting will change if the control method is changed. The factory settings given above are for V/f without PG control.
3. Factory setting depends on the control method (A1-02).
4. For V/f with PG control: 1.0
5. For Inverters with a capacity of 55 kW or more: 2.00
6. Setting range and initial setting depend on Inverter capacity.
7. Setting for 200 V class Inverters. For 400 V class Inverters, double the value.
8. Factory setting in the parentheses is for 3-wire sequence.
9. The contents is ignored if the setting is 0.0.
10.E1-13 will have the same value as E1-05 after autotuning.
11.If the set value is 0, acceleration will be to the speeds for the acceleration times (C1-01 to C1-08)
12.The setting range is 10% to 200% of the Inverter rated output. (The value given is for a 200 V Class Inverter for 0.4 kW.)
