SAFETY INSTRUCTIONS
1. Electric Shock Prevention
WARNING
While power is on or when the inverter is running, do not open the front cover.
You may get an electric shock.
Do not run the inverter with the front cover removed. Otherwise, you may access
the exposed high-voltage terminals or the charging part of the circuitry and get
an electric shock.
If power is off, do not remove the front cover except for wiring or periodic
inspection. You may access the charged inverter circuits and get an electric
shock.
Before starting wiring or inspection, s witch power off, wait for more than 10
minutes, and check for residual voltage with a meter (refer to chapter 2 forfurther
details) etc.
Earth the Inverter.
Any person who is involved in the wiring or inspection of this equipment should
be fully competent to do the work.
Always install the inverter before wiring. Otherwise, you may get an electric
shock or be injured.
Operate the switches and potentiometers with dry hands to prevent an electric
shock.
Do not subject the cables to scratches, excess ive stress, heavy loads or
pinching. Otherwise, you may get an electric shock.
Do not change the cooling fan while power is on.
It is dangerous to change the cooling fan while power is on.
2. Fire Prevention
CAUTION
Mount the inverter and brake re sistor on an incombustible surface. Installing the
inverter directly on or near a combustible surface could lead to a fire.
If the inverter has become faulty, switch off the inverter power. A continuous flow
of large current could cause a fire.
When a brake resistor is used, use an alarm signal to switch power off.
Otherwise, the brake resistor will overheat abnormally due a brake transistor or
other fault, resulting in a fire.
Do not connect a resistor directly to the DC terminals +, −. This could cause a
fire.
A-2
3. Injury Prevention
CAUTION
Apply only the voltage specified in the instruction manual to each terminal to
prevent damage etc.
Ensure that the cables are connected to the correct terminals. Otherwise,
damage etc. may occur.
Always make sure that polarity is correct to prevent damage etc.
While power is on and for some time after power-off, do not touch the inverter or
brake resistor as they are hot and you may get burnt.
4. Additional instructions
Also note the following points to prevent an accidental failure, injury, electric shock, etc.
(1) Transportation and installation
CAUTION
Environment
When carrying products, use correct lifting gear to prevent injury.
Do not stack the inverter boxes higher than the number recommended.
Ensure that installation position and material can withstand the weight of the
inverter. Install according to the information in the Instruction Manual.
Do not operate if the inverter is damaged or has parts missing.
Do not hold the inverter by the front cover or operation panel; it may fall off.
Do not stand or rest heavy objects on the inverter.
Check the inverter mounting orientation is correct.
Prevent screws, wire fragments or other conductive bodies or oil or other
flammable substance from entering the inverter.
Do not drop the inverter, or subject it to impact.
Use the inverter under the following environmental conditions:
Ambient
Constant torque : -10°C to +50°C (non-freezing)

that derate by 3% for every extra 500m up to 2500m (91%).
*Temperatures applicable for a short time, e.g. in transit.
A-3
(2) Wiring
CAUTION
Do not fit capacitive equipment such as power factor correction capacitor, noise
filter or surge suppressor to the output of the inverter.
The connection orientation of the output cables U, V, W to the motor will affect
the direction of rotation of the motor.
(3) Trial run
CAUTION
Check all parameters, and ensure that the machine will not be damaged by a
sudden start-up.
(4) Operation
WARNING
When you have chosen the retry function, stay away from the equipment as it will
restart suddenly after an alarm stop.
The [STOP] key is valid only when the appropriate function setting has been
made. Prepare an emergency stop switch separately.
Make sure that the start signal is off before resetting the inverter alarm. A failure
to do so may restart the motor suddenly.
The load used should be a three-phase induction motor only. Connection of any
other electrical equipment to the inverter output may damage the equipment.
Do not modify the equipment.
A-4
CAUTION
The electronic overcurrent protection does not guarantee protection of the motor
from overheating.
Do not use a magnetic contactor on the inverter in put for frequent
starting/stopping of the inverter.
Use a noise filter to reduce the effect of electromagnetic interference. Otherwise
nearby electronic equipment may be affected.
Take measures to suppress harmonics. Otherwise power harmonics from the
inverter may heat/damage the power capacitor and generator.
When a 400V class motor is inverter-driven, it should be insulation-enhanced or
surge voltages suppressed. Surge voltages attributable to the wiring constants
may occur at the motor terminals, deteriorating the insulation of the motor.
When parameter clear or all clear is performed, each parameter returns to the
factory setting. Re-set the required parameters before starting operation.
The inverter can be easily set for high-speed operation. Before changing its
setting, fully examine the performances of the motor and machine.
In addition to the inverter's holding function, install a holding device to ensure
safety.
Before running an inverter which had been stored for a long period, always
perform inspection and test operation.
(5) Emergency stop
CAUTION
Provide a safety backup such as an emergency brake which will prevent the
machine and equipment from hazardous conditions if the inverter fails.
(6) Maintenance, inspection and parts replacement
CAUTION
Do not carry out a megger (insulation resistance) test on the control circuit of the
inverter.
(7) Disposing of the inverter
CAUTION
Treat as industrial waste.
(8) General instructions
Many of the diagrams and drawings in this instruction manual show the inverter
without a cover, or partially open. Never operate the inverter like this. Always
replace the cover and follow this instruction manual when operating the inverter.

Japanese Harmonic Suppression Guideline
The "harmonic suppression guideline for household appliances and general-purpose
products" was issued by the Ministry of International Trade and Industry in
September, 1994. This guideline applies to the 2.2K and less models of single-phase
200V classes. By installing the power factor improving reactor (FR-BEL or FR-BAL),
inverters comply with the "harmonic suppression techniques for transistorized
inverters (input current 20A or less)" established by the Japan Electrical
Manufacturers' Association.

2.1 Installation
2.1.1 Instructions for installation
1) Handle the unit carefully.
The inverter uses plastic parts. Handle it gently to protect it from damage.
Also, hold the unit with even strength and do not apply too much strength to the front
cover alone.
2) Install the inverter in a place where it is not affected by vibration easily (5.9m/s
{0.6G} maximum).
Note the vibration of a cart, press, etc.
2
3) Note on ambient temperature.
The inverter life is under great influence of ambient temperature. In the place of
installation, ambient temperature must be within the permissible range –10 °C to
+50°C. Check that the ambient temperature is within that range in the positions
shown in figure 3.
4) Install the inverter on a non-combustible surface.
The inverter will be very hot (maximum about 150 °C). Install it on a non-combustible
surface (e.g. metal). Also leave sufficient clearances around the inverter.
5) Avoid high temperature and high humidity.
Avoid direct sunlight and places of high temperature and high humidity.
6) Avoid places where the inverter is exposed to oil mist, flammable gases, fluff, dust,
dirt etc.
Install the inverter in a clean place or inside a "totally enclosed" panel which does not
accept any suspended matter.
7) Note the cooling method when the inverter is installed in an enclosure.
When two or more inverters are installed or a ventilation fan is mounted in an
enclosure, the inverters and ventilation fan must be installed in proper positions with
extreme care taken to keep the ambient temperatures of the inverters with the
permissible values. If they are installed in improper positions, the ambient
temperatures of the inverters will rise and ventilation effect will be reduced.
8) Install the inverter on an installation surface securely and vertically with screws or
bolts.

INSTALLATION AND WIRING
2.2.2 Wiring of the Main Circuit
(1) Wiring instructions
1) It is rec ommended to use insulation-sleeved solderless terminals for power supply
and motor wiring.
2) Power must not be applied to the output terminals (U, V, W) of the inverter.
Otherwise the inverter will be damaged.
3) After wiring, wire off-cuts must not be left in the inverter.
Wire off-cuts can cause an alarm, failure or malfunction. Always keep the inverter clean.
When drilling mounting holes in a control box or the like, be careful so that chips and
others do not enter the inverter.
4) Use thick cables to make the voltage drop 2% or less.
If the wiring distance is long between the inverter and motor, a main circuit cable
voltage drop will cause the motor torque to decrease, especially at the output of a low
frequency. (A selection example for the wiring length of 20m is shown on page 19.)
5) For long distance wiring, the overcurrent protection may be activated improperly or
the devices connected to the output side may misoperate or become faulty under the
influence of a charging current due to the stray capacitance of the wiring. Therefore,
the maximum overall wiring length should be as indicated in the following table. If the
wiring length exceeds the value, it is recommended to set "1" in Pr. 156 to make the
fast-response current limit function invalid. (When two or more motors are connected
to the inverter, the total wiring length should be within the indicated value.)

INSTALLATION AND WIRING
6) Connect only the recommended optional brake resistor between the + - PR.
These terminals must not be shorted.
7) Electromagnetic wave interference
The input/output (main circuit) of the inverter includes harmonic components, which
may interfere with the communication devices (such as AM radios) used near the
inverter. In this case, install the FR-BIF optional radio noise filter (for use in the input
side only) or FR-BSF01 or FR-BLF line noise filter to minimize interference.
8) Do not install a power capacitor, surge suppressor or radio noise filter (FR-BIF
option) in the output side of the inverter.
This will cause the inverter to trip or the capacitor and surge suppressor to be
damaged. If any of the above devices are installed, immediately remove them.
(When using the FR-BIF radio noise filter with a single-phase power supply, connect
it to the input side of the inverter after isolating the T phase securely.)
9) When rewiring after operation, make sure that the POWER lamp has gone off, and
when more than 10 minutes has elapsed after power-off, check with a meter etc. that
the voltage is zero. After that, start rewiring work. For some time after power-off,
there is a dangerous voltage in the capacitor.
Notes on Earthing (Grounding)
• Leakage currents flow in the inverter. To prevent an electric shock, the inverter
and motor must be earthed (grounded).
• Use the dedicated earth (ground) terminal to earth (ground) the inverter. (Do not
use the screw in the case, chassis, etc.) For the earth connection avoid direct
contact between aluminium and copper. Tin-plated cable lugs can be used if the
plating does not contain zinc. When tightening the screws take care not to damage
the thread in the aluminium frame.
• The earth (ground) cable should be as thick as possible. Use the cable whose
gauge is equal to or larger than those indicated in the following table, and make its
length as short as possible. The earthing (grounding) point should be as near as
possible to the inverter to minimize the earth (ground) cable length.

INSTALLATION AND WIRING
2.2.3 Wiring of the control circuit
(1) Wiring instructions
1) Terminals PC, SE and 5 (and SD when sink logic is selected) are common to the I/O
signals. These common terminals must not be earthed to the ground.
2) Use shielded or twisted cables for connection to the control circuit terminals and run
them away from the main and power circuits (including the 200V relay sequence
circuit).
3) The frequency input signals to the control circuit are micro currents. When contacts
are required, use two or more parallel micro signal contacts or a twin contact to
prevent a contact fault.
4) It is recommended to use the cables of 0.3mm2 to 0.75mm2 gauge for connection to
the control circuit terminals.
5) When bar terminals and solid wires are used for wiring, their diameters should be
0.9mm maximum If they are larger, screw threads may be damaged during
tightening.

(3) Wiring method
1) For wiring the control circuit, use cables after stripping their sheaths.
Refer to the gauge printed on the inverter and strip the sheaths to the following
dimensions. If the sheath is stripped too much, its cable may be shorted with the
adjoining cable. If the sheath is stripped too little, the cable may come off.
7mm±1mm

INSTALLATION AND WIRING
2) When using bar terminals and solid wires for wiring, their diameters should be
0.9mm maximum. If they are larger, the threads may be damaged during tightening.
3) Loosen the terminal screw and insert the cable into the terminal.
4) Tighten the screw to the specified torque.
Undertightening can cause cable disconnection or misoperation. Overtightening can
cause damage to the screw or unit, leading to short circuit or misoperation.
Tightening torque: 2.5kg×cm
Note:
When routing the stripped cables, twist them so that they do not become loose.
(4) Control logic changing
The input signal logic is factory-set to the source mode.
To change the control logic, the position of the connector beside the control circuit
terminal block must be changed.
1) Use tweezers etc. to remove the connector in the source logic position and fit it in the
sink logic position.
Do this position changing before switching power on.
Note: 1. Make sure that the front cover has been installed securely.
2. The front cover has a capacity plate and the inverter a rating plate on it.
Since these plates have the same serial numbers, always reinstall the
removed cover to the inverter from where it was removed.
3. Always install the sink-source logic changing connector in either of the
positions. If two connectors are installed in these positions at the same time,
the inverter may be damaged.

2.2.6 Design information
1) Provide electrical and mechanical interlocks for MC1 and MC2 which are used for
commercial power supply-inverter switch-over.
When there is a commercial power supply-inverter switch-over circuit as shown
below, the inverter will be damaged by leakage current from the power supply due to
arcs generated at the time of switch-over or chattering caused by a sequence error.
2) If the machine must not be restarted when power is restored after a power failure,
provide a magnetic contactor in the inverter's primary circuit and also make up a
sequence which will not switch on the start signal.
If the start signal (start switch) remains on after a power failure, the inverter will
automatically restart as soon as the power is restored.
3) Since the input signals to the control circuit a re on a low level, use two or more
parallel micro signal contacts or a twin contact for contact inputs to prevent a contact
fault.
4) Do not apply a large voltage to the contact input terminals (e.g. STF) of the control
circuit.
5) Do not apply a voltage directly to the alarm output signal terminals (A, B, C).
Always apply a voltage to these terminals via a relay coil, lamp, etc.
6) Make sure that the specifications and rating match the system requirements.

protection is activated. Hence, when the motor is driven by the inverter, do not
install a capacitor or surge suppressor on the inverter's output side. To
improve the power factor, insert a power factor improving reactor in the
inverter's input or DC circuit. For details, refer to the FR-A500/E500 series

INSTALLATION AND WIRING
2.3.2 Japanese harmonic suppression guideline
Harmonic currents flow from the inverter to a power receiving point via a power
transformer. The harmonic suppression guideline was established to protect other
consumers from these outgoing harmonic currents.
1) "Harmonic suppression guideline for household appliances and general-purpose
products"
This guideline was issued by the Ministry of International Trade and Industries in
September, 1994 and applies to 200V class single phase input inverters of 2.2kW
and less. By installing the FR-BEL or FR-BAL power factor improving reactor,
inverters comply with the "haramonic suppression techniques for transistorized
inverters (input current 20A or less)" established by the Japan Electrical
Manufacturers′ Association. Therefore install the optional reactor for the 200V class,
2.2kW or less inverter.
2.3.3 Inverter-generated noise and reduction techniques
Some noises enter the inverter causing it to incorrectly operate, and others are radiated
by the inverter causing misoperation of peripheral devices. Though the inverter is
designed to be insusceptible to noise, it handles low-level signals, so it requires the
following basic measures to be taken. Also, since the inverter chops the output at high
carrier frequencies, it could generate noise. If these noises cause peripheral devices to
misoperate, measures should be taken to suppress noise. The measures differ slightly
depending on noise propagation paths.
1) Basic measures
Do not run the power cables (I/O cables) and signal cables of the inverter in
parallel with each other and do not bundle them.
Use twisted shield cables for the detector connecting and control signal cables
and connect the sheathes of the shield cables to terminal SD.
Earth (Ground) the inverter, motor, etc. at one point.
2) Measures against noise which enters and causes misoperation of the inverter
When devices which generate noise (devices which use magnetic contactors,
magnetic brakes, many relays, for example) are installed near the inverter, the
inverter may misoperate due to noise. The following measures must be taken:
Provide surge suppressors for devices that generate noise to suppress noise.
Fit data line filters (Refer to page 36) to signal cables.
Ground the shields of the detector connection and control signal cables with cable
clamp metal.
33
INSTALLATION AND WIRING
3) Measures against noises which are radiated by the inverter causing misoperation of
peripheral devices.
Inverter-generated noises are largely classified into those radiated by the cables
connected to the inverter and inverter main circuit (I/O), those electromagnetically
and electrostatically inducted to the signal cables of the peripheral devices close to
the main circuit power supply, and those transmitted through the power supply
cables.

Measures
When devices which handle low-level signals and are susceptible to
misoperation due to noise (such as instruments, receivers and sensors)
are installed near the inverter and their signal cables are contained in the
same panel as the inverter or are run near the inverter, the devices may
be misoperated by air-propagated noise and the following measures must
be taken:
(1) Install e asily affected devices as far away as possible from the
inverter.
(2) Run easily affected signal cables as far away as possible from the
inverter.
(3) Do not run the signal cables and power cables (inverter I/O cables) in
parallel with each other and do not bundle them.
(4) Insert line noise filters onto I/O and radio noise filters into inputs to
suppress cable-radiated noises.
(5) Use shielded cables for signal cables and power cables and run them
in individual metal conduits to further reduce effects.
When the signal cables are run in parallel with or bundled with the power
cables, magnetic and static induction noises may be propagated to the
signal cables causing misoperation of the devices and the following
measures must be taken:
(1) Install easily affected devices as far away as possible from the
inverter.
(2) Run easily affected signal cables as far away as possible from the
inverter.
(3) Do not run the signal cables and power cables (inverter I/O cables) in
parallel with each other and do not bundle them.
(4) Use shielded cables for signal cables and power cables and run them
in individual metal conduits to further reduce effects.
When the power supplies of the peripheral devices are connected to the
power supply of the inverter within the same line, inverter-generated noise
may flow back through the power supply cables causing misoperation of
the devices and the following measures must be taken:
(1) Install the radio noise filter (FR-BIF) to the power cables (input cables)
of the inverter.
(2) Install the line noise filter (FR-BLF, FR-BSF01) to the power cables
(I/O cables) of the inverter.
When a closed loop circuit is formed by connecting the peripheral device
wiring to the inverter, leakage current may flow through the ground cable
of the inverter causing misoperation of the device. In such a case,
disconnection of the ground cable of the device may cause the device to
operate properly.

2.3.4 Leakage currents and countermeasures
Due to the static capacitance existing in the inverter I/O wiring and motor, leakage
currents flow through them. Since their values depend on the static capacitance, carrier
frequency, etc., take the following measures.
(1) To-earth (ground) leakage currents
Leakage currents may flow not only into the inverter's own line but also into the other
lines through the earth (ground) cable, etc. These leakage currents may operate earth
leakage circuit breakers and earth leakage relays unnecessarily.
Countermeasures
If the carrier frequency setting is high, decrease the carrier frequency (Pr. 72) of
the inverter.
Note that motor noise increases. Selection of Soft-PWM (Pr. 240) will make it
unoffending.
By using earth leakage circuit breakers durable against harmonics and surges
(e.g. Mitsubishi's Progressive Super Series) in the inverter's own line and other
line, operation can be performed with low noise (with the carrier frequency kept
high).
To-earth (ground) leakage current
Note that a long wiring length will increase leakage currents. Decrease the carrier
frequency of the inverter to reduce leakage currents.
Higher motor capacity leads to larger leakage currents. The leakage currents of
the 400V class are higher than those of the 200V class.
(2) Line-to-line leakage currents
Harmonics of leakage currents flowing in static capacities between the inverter output
cables may operate the external thermal relay unnecessarily. When the wiring length is
long (50m or more) for the 400V class, the external thermal relay is likely to operate
unnecessarily because the ratio of the leakage current to the rated motor current
increases.

To ensure that the motor is protected against line-to-line leakage currents, it is
recommended to use a temperature sensor to directly detect motor temperature.
2.3.5 Inverter-driven 400V class motor
In the PWM type inverter, a surge voltage attributable to wiring constants is generated
at the motor terminals. Especially for a 400V class motor, the surge voltage may
deteriorate the insulation. When the 400V class motor is driven by the inverter, consider
the following measures:
Measures
It is recommended to take either of the following measures:
(1) Rectifying the motor insulation
For the 400V class motor, use an insulation-rectified motor. Specifically
1) Specify the "400V class inverter-driven, insulation-rectified motor".
2) For the dedicated motor such as the constant-torque motor and
low-vibration motor, use the "inverter-driven, dedicated motor".

(2) Suppressing the surge voltage on the inverter side
On the secondary side of the inverter, connect the optional surge voltage
suppression filter (FR-ASF-H).

39
INSTALLATION AND WIRING
Installation and selection of no-fuse breaker
Install a no-fuse breaker (NFB) in the power supply side for protection of the
inverter's primary wiring. Refer to the above table and choose the NFB according to
the inverter's power supply side power factor (which changes with the power supply
voltage, output frequency and load). Especially for a completely electromagnetic type
NFB, the one with a larger capacity must be selected since its operational
characteristics change with harmonic currents. (Check the data of the corresponding
breaker for confirmation.) Also the earth leakage circuit breaker used should be our
product durable against harmonics/surges (such as the Progressive Super Series).
Power factor improving reactor
When the inverter is connected near a
large-capacity power supply transformer
(500kVA or more, wiring length 10m
maximum) or there is power capacitor
switch-over, excessive peak currents may
flow into the power input circuit and
damage the converter circuit. In such a
case, the power supply improving reactor
(FR-BEL or FR-BAL) must be installed.
Note:
For use with a less than 0.4kW
motor, choose a reactor designed for
0.4kW. Note that its power factor
improving effect is slightly smaller.

Note: 1. The earth leakage circuit breaker should be installed to the primary (power
supply) side of the inverter.
2. Ground fault in the secondary side of the inverter can be detected at the
running frequency of 120Hz or lower.
3. In the
connection neutral point grounded system, the sensitivity current
becomes worse for ground fault in the inverter secondary side. Hence, the
protective grounding of the load equipment should be class D grounding (10 Ω
or less).
4. When the breaker is grounded on the secondary side of the inverter, it may be
unnecessarily operated by harmonics if the effective value is less than the
rating. In this case, note that the eddy current and hysteresis loss increase and
temperature rises.

INSTALLATION AND WIRING
2.3.8 Instructions for compliance with the European standards
(The products conforming to the Low Voltage Directive carry the CE mark.)
(1) EMC Directive
1) Our view of transistorized inverters for the EMC Directive
A transistorized inverter does not function independently. It is a component
designed for installation in a control box and for use with the other equipment to
control the equipment/device. Therefore, we understand that the EMC Directive
does not apply directly to transistorized inverters. For this reason, we do not
place the CE mark on the transistorized inverters themselves. (The CE mark is
placed on inverters in accordance with the Low Voltage Directive.) The
European power drive manufacturers' organization (CEMEP) also holds this
point of view.
2) Compliance
We understand that the transistorized inverters themselves are not covered
directly by the EMC Directive. However, the EMC Directive applies to
machines/equipment into which transistorized inverters have been incorporated,
and these machines and equipment must carry the CE marks. Hence, we
prepared the technical information "EMC Installation Guidelines" (information
number BCN-A21041-202) so that machines and equipment incorporating
transistorized inverters may conform to the EMC Directive more easily.
3) Outline of installation method
Install an inverter using the following methods:
* Use the inverter with an European Standard-compliant noise filter.
* For wiring between the inverter and motor, use shielded cables or run them in
a metal piping and ground the cables on the inverter and motor sides with the
shortest possible distance.
* Insert a line noise filter and ferrite core into the power and control lines as
required.
Full information including the European Standard-compliant noise filter
specifications are written in the technical information "EMC Installation
Guidelines" (BCN-A21041-202). Please contact your sales representative.

INSTALLATION AND WIRING
(2) Low Voltage Directive
1) Our view of transistorized inverters for the Low Voltage Directive
Transistorized inverters are covered by the Low Voltage Directive.
2) Compliance
We have self-confirmed our inverters as products compliant to the Low Voltage
Directive and place the CE mark on the inverters.
3) Outline of instructions
* In the 400V class inverters, the rated input voltage range is three-phase, 380V
to 415V, 50Hz/60Hz.
* Connect th e equipment to the earth (ground) securely. Do not use an earth
leakage circuit breaker as an electric shock protector without connecting the
equipment to the earth (ground).
* Wire the earth terminal independently. (Do not connect two or more cables to
one terminal.)
* The wire size on pages 18 and 19 are shown for following conditions.
Ambient Temp:
40°C maximum
Wire installation: On wall without duct or conduits
If conditions are different from above, select appropriate wire according to
EN60204 ANNEX C TABLE 5.
* Use the no-fuse breaker and magnetic contactor which conform to the EN or
IEC Standard.
Design notice: Where residual-current-operated protective device (RCD) is
used for protection in case of direct or indirect contact, only
RCD of Type B is allowed on the supply side of this Electronic
Equipment (EE). Otherwise another protective measure shall
be applied such as separation of the EE from the environment
by double or reinforced insulation or isolation of EE and supply
system by a transformer. (Extract from EN51078)
* Use the inverter under the conditions of overvoltage category II and
contamination level 2 or higher specified in IEC664.
(a) To meet the overvoltage category II, in
sert an EN or IEC standardcompliant earthed star connection isolation transformer in the input of the
inverter.
(b) To meet the contamination level 2, install the inverter in a control box
protected against ingress of water, oil, carbon, dust, etc. (IP54 or higher).
* On the input and output of the inverter, use cables of the type and size set
forth in EN60204 Appendix C.
* The operating capacity of the relay outputs (terminal symbols A, B, C) should
be 30VDC, 0.3A.

3.3 Operation
3.3.1 Pre-operation checks
Before starting operation, check the following:
Safety
Perform test operation after making sure that safety is ensured if the machine should
become out of control.
Machine
Make sure that the machine is free of damage.
Parameters
Set the parameter values to match the operating machine (system) environment.
Test operation
Perform test operation and make sure that the machine operates safely under light
load at a low frequency. After that, start operation.
Since the Pr. 240 "Soft-PWM setting" value is factory-set to select Soft-PWM control,
the tone is different from that in the conventional non-low acoustic noise mode, this
is not a fault.

Function
Note: 1. Indicates the parameter of which setting is ignored when the generalpurpose magnetic flux vector control mode is selected.
2. Since calibration is made before shipment from the factory, the settings differ
slightly between inverters. The inverter is preset to provide a frequency
slightly higher than 50Hz.
3. When the control panel is used and the setting is 100Hz or more, the setting
increments are 0.1Hz.
4. The setting depends on the inverter capacity: (0.4K to 3.7K)/(5.5K to 7.5K).
5. Set to 85% of the rated inverter current for the 0.4K, 0.75K.
6. If "2" is set in Pr. 77 (parameter write inhibit selection), the setting cannot be
changed during operation.
7. The half-tone screened parameters allow their settings to be changed during
operation if "0" (factory setting) has been set in Pr. 77 (parameter write inhibit
selection). (However, the Pr. 72 value may be changed during PU operation
only.)
8. The setting depends on the inverter capacity: 4% for the FR-E540-5.5K and
7.5K-EC.

Set the output current level at which the output frequency is adjusted to prevent the

For high-speed operation at or over the motor base frequency, acceleration may not
be made because the motor current does not increase.
To improve the operation characteristics of the motor in such a case, the stall
prevention level in the high-frequency range can be reduced. This is effective for
operation of a centrifugal separator up to the high-speed range. Normally, set 50Hz
in Pr. 66 and 100% in Pr. 23.
For operation in the high-frequency range, the current in the locked motor state is
smaller than the rated output current of the inverter and the inverter does not result in
an alarm (protective function is not activated) if the motor is at a stop. To improve
this and activate the alarm, the stall prevention level can be reduced.

Description
Linear acceleration/deceleration is made up/down to the
preset frequency (factory setting).
For machine tool spindles
This setting is used when it is necessary to make
acceleration/deceleration in a short time up to the base
frequency or higher speed range.
In this acceleration/deceleration pattern, fb (base frequency)
is always the inflection point of an S shape, and you can set
the acceleration/deceleration time according to the reduction
in motor torque in the base frequency or higher constantoutput operation range.
For prevention of cargo collapse on conveyor, etc.
This setting provides S-shaped acceleration/deceleration
from f2 (current frequency) to f1 (target frequency), easing
an acceleration/deceleration shock. This pattern has an
effect on the prevention of cargo collapse, etc.
Note: For the acceleration/deceleration time, set the time required to reach the "base
frequency" in Pr. 3, not the "acceleration/deceleration reference frequency" in
Pr. 20. For details, refer to Pr. 7 and Pr. 8.

Waiting time for inverter-triggered restart after power is restored

second and 5 seconds according to the inertia moment (GD )
and torque of the load.)
No restart
Normally the inverter may be run with the factory settings. These
values are adjustable to the load (inertia moment, torque).
Note: 1. Automatic restart after instantaneous power failure uses a reduced-voltage
starting system in which the output voltage is raised gradually with the preset
frequency unchanged, independently of the coasting speed of the motor.
As in the FR-A024S/A044, a motor coasting speed detection system (speed
search system) is not used but the output frequency before an instantaneous
power failure is output. Therefore, if the instantaneous power failure time is
longer than 0.2 seconds, the frequency before the instantaneous power
failure cannot be stored and the inverter will start at 0Hz.
2. The SU and FU signals are not output during restart but are output after the
restart cushion time has elapsed.
CAUTION
When automatic restart after instantaneous power failure has been
selected, the motor and machine will start suddenly (after the reset time
has elapsed) after occurrence of an instantaneous power failure.
Stay away from the motor and machine.
When you have selected automatic restart after instantaneous power
failure, apply the supplied CAUTION seals in easily visible places.
When the start signal is turned off or the STOP key is pressed during the
cushion time for automatic restart after instantaneous power failure,
deceleration starts after the automatic restart cushion time set in Pr. 58

When "remote setting function - yes" is selected, the functions of signals RH, RM
and RL are changed to acceleration (RH), deceleration (RM) and clear (RL). Use Pr.
180 to Pr. 183 (input terminal function selection) to set signals RH, RM and RL.
Note: 1. The frequency can be varied by RH (acceleration) and RM (deceleration)
between 0 and the maximum frequency (Pr. 1 or Pr. 18 setting).
2. When t he acceleration or deceleration signal switches on, the set frequency
varies according to the slope set in Pr. 44 or Pr. 45. The output frequency
acceleration/deceleration times are as set in Pr. 7 and Pr. 8, respectively.
Therefore, the longer preset times are used to vary the actual output frequency.
3. If the start signal (STF or STR) is off, turning on the acceleration (RH) or
deceleration (RM) signal varies the set frequency.
4. The frequency setting storage function stores in memory the remotely-set
frequency (frequency set by RH/RM operation) when the acceleration and
deceleration signals remain off for more than 1 minute or as soon as the start
signal (STF or STR) switches off. When power is switched off once, then on,
operation is resumed with that value.

Use Pr. 68 to set the waiting time from when an inverter alarm occurs until a restart
in the range 0.1 to 360 seconds.
Reading the Pr. 69 value provides the cumulative number of successful restart times
made by retry. The setting of "0" erases the cumulative number of times.
Note: 1. The cumulative number in Pr. 69 is incremented by "1" when retry operation
is regarded as successful, i.e. when normal operation is continued without
the protective function (major fault) activated during a period five times
longer than the time set in Pr. 68.
2. If the protective function (major fault) is activated consecutively within a
period five times longer than the above waiting time, the control panel may
show data different from the most recent data or the parameter unit
(FR-PU04) may show data different from the first retry data. The data stored
as the error reset for retry is only that of the protective function (major fault)
which was activated the first time.
3. When an inverter alarm is reset by the retry function at the retry time, the
stored data of the electronic over current protection, etc. are not cleared.
(Different from the power-on reset.)
CAUTION
When you have selected the retry function, stay away from the motor and

PARAMETERS
Note: 1. By entering the reset signal (RES) during operation, the inverter shuts off
output while it is reset, the data of the electronic overcurrent protection and
regenerative brake duty are reset, and the motor coasts.
2. The PU disconnection detection function judges that the PU is disconnected
when it is removed from the inverter for more than 1 second. If the PU had
been disconnected before power-on, it is not judged as an alarm.
3. To resume operation, reset the inverter after confirming that the PU is
connected securely.
4. The Pr. 75 value can be set any time. Also, if parameter (all) clear is
executed, this setting will not return to the initial value.
5. When the inverter is stopped by the PU stop function, PS is displayed but an
alarm is not output.
When the PU connector is used for RS-485 communication operation, the
reset selection and PU stop selection functions are valid but the PU
disconnection detection function is invalid.
CAUTION
Do not reset the inverter with the start signal on.
Otherwise, the motor will start instantly after resetting, leading to
potentially hazardous conditions.

Rotation direction is determined by the external operation
input signal.
Set frequency is determined by the external frequency

from being inoperative by the external command if the mode is accidentally left
unswitched from the PU operation mode.

The general-purpose magnetic flux vector control can be used without using the
offline auto tuning function but if the motor used is not Mitsubishi's standard motor or
Mitsubishi's constant-torque motor (e.g. motor of another company make) or the
wiring distance is long, the motor can be run with the optimum operating
characteristics by using the offline auto tuning function.
Offline auto tuning
Automatically measures the motor constants used for general-purpose magnetic flux
vector control.
Offline auto tuning can be performed with the load connected. (As the load is
smaller, tuning accuracy is higher. Tuning accuracy does not change if inertia is
large.)
The offline auto tuning status can be monitored with the control panel
(FR-PA02-02) or PU (FR-PU04).
Offline auto tuning is available only when the motor is at a stop.
Tuning data (motor constants) can be copied to another inverter with the PU
(FR-PU04).
You can read, write and copy the motor constants tuned by the offline auto tuning.

<Operating conditions>
The motor is connected.
The motor capacity is equal to or one rank lower than the inverter capacity.
Special motors such as high-slip motors and high-speed motors cannot be tuned.
The motor may move slightly. Therefore, fix the motor securely with a mechanical
brake, or before tuning, make sure that there will be no problem in safety if the
motor runs.
*This instruction must be followed especially for vertical lift applications.
If the motor runs slightly, tuning performance is unaffected.
Offline auto tuning will not be performed properly if it is started when a reactor or

Note: 1. The R1 motor constant measured during in the offline auto tuning is stored
as a parameter and its data is held until the offline auto tuning is performed
again.
2. An instantaneous power failure oc curring during tuning will result in a tuning
error.
After power is restored, the inverter goes into the ordinary operation mode.
Therefore, when STF (STR) is on, the motor runs in forward (reverse)
rotation.
3. Any alarm occurring during tuning is hand led as in the ordinary mode. Note
that if an error retry has been set, retry is ignored.
4. The set frequency monitor displayed during the offline auto tuning is 0Hz.
CAUTION
When the offline auto tuning is used in vertical lift application, e.g. a lifter,
it may drop due to insufficient torque.

<Operating procedure>
1. Set "801" in Pr. 77. Only when the Pr. 80 setting is other than "9999", the
parameter value of the motor constant (Pr. 90) can be displayed. Though the
parameter values of other than the motor constant (Pr. 90) can also be displayed,
they are parameters for manufacturer setting and should be handled carefully
without misuse.
2. Set any of the following values in Pr. 71:

the inverter. Hence, the inverter can be run and monitored in various ways by
specifying the instruction code as appropriate. (Refer to page 185.)
4) Data
Indicates the data such as frequency and parameters transferred to and from the
inverter. The definitions and ranges of set data are determined in accordance with
the instruction codes. (Refer to page 185.)
5) Waiting time
Specify the waiting time between the receipt of data at the inverter from the computer
and the transmission of reply data. Set the waiting time in accordance with the
response time of the computer between 0 and 150ms in 10ms increments

PARAMETERS
Note: 1. When the data from th e computer has an error, the inverter will not accept
that data.
2. Any data communication, e.g. run command, monitoring, is started when the
computer gives a communication request. Without the computer's command,
the inverter does not return any data. For monitoring, therefore, design the
program to cause the computer to provide a data read request as required.

CAUTION
When the inverter's permissible communication time interval is not set,
interlocks are provided to disable operation to prevent hazardous
conditions. Always set the communication check time interval before
starting operation.
Data communication is not started automatically but is made only once
when the computer provides a communication request. If communication
is disabled during operation due to signal cable breakage etc, the inverter
cannot be stopped. When the communication check time interval has
elapsed, the inverter will come to an alarm stop (E.PUE).
The inverter can be coasted to a stop by switching on its RES signal or by
switching power off.
If communication is broken due to signal cable breakage, computer fault
etc, the inverter does not detect such a fault. This should be fully noted.

When the inverter's output current falls to "0", torque will not be generated. This may
cause a gravity drop when the inverter is used in vertical lift application.
To prevent this, the output current "zero" signal can be output from the inverter to close
the mechanical brake when the output current has fallen to "zero".
If the output current remains lower than the Pr. 152 setting during inverter operation
for longer than the time set in Pr. 153, the zero current detection (Y13) signal is

CAUTION
The zero current detection level setting should not be too high, and the
zero current detection time setting should not be too long. Otherwise, the
detection signal may not be output when torque is not generated at a low

(Alarm stop display "E.OLT")
2: If the load is heavy, the lift is predetermined, or the acceleration/deceleration
time is short, the stall prevention may be activated and the motor not
stopped in the preset acceleration/deceleration time. Therefore, set optimum
values to the Pr. 156 and stall prevention operation level.
CAUTION
Always perform test operation.
Stall prevention operation performed during acceleration may increase
the acceleration time.
Stall prevention operation performed during constant speed may cause
sudden speed changes.
Stall prevention operation performed during deceleration may increase
the deceleration time, increasing the deceleration distance.

If any fault has occurred in the inverter, the corresponding protective function is activated
to bring the inverter to an alarm stop and automatically give the corresponding error
(alarm) indication on the optional control panel or the parameter unit display.
If your fault does not correspond to any of the following errors or if you have any other
problem, please contact your sales representative.
• Retention of alarm output signal .... When the magnetic contactor (MC) provided on
the power supply side of the inverter is opened at
the activation of the protective function, the
inverter's control power will be lost and the alarm
output will not be held.
• Alarm indication ............................. When the protective function is activated, the
operation panel display automatically switches to
the above indication.
• Resetting method .......................... When the protective function is activated, the
inverter output is kept stopped. Unless reset,
therefore, the inverter cannot restart. Switch
power off once, then on again; or apply RES
signal for more than 0.1 seconds. Kept on, "Err."

5.3 Precautions for Maintenance and Inspection
PROTECTIVE FUNCTIONS
5.3 Precautions for Maintenance and Inspection
The transistorized inverter is a static unit mainly consisting of semiconductor devices.
Daily inspection must be performed to prevent any fault from occurring due to adverse
influence by the operating environment, such as temperature, humidity, dust, dirt and
vibration, changes in the parts with time, service life, and other factors.
5.3.1 Precautions for maintenance and inspection
For some short time after the power is switched off, a high voltage remains in the
smoothing capacitor. Therefore, when more than 10 minutes have elapsed after poweroff, make sure that the voltage across the main circuit terminals + - − of the inverter is
30VDC or less using a meter, etc. Then, access the inverter for inspection.
5.3.2 Check items
(1) Daily inspection
Check the following:
1) Motor operation fault
2) Improper installation environment
3) Cooling system fault
4) Unusual vibration and noise
5) Unusual overheating and discoloration
During operation, check the inverter input voltages using a meter.
(2) Cleaning
Always run the inverter in a clean state.
When cleaning the inverter, gently wipe dirty areas with a soft cloth immersed in neutral
detergent or ethanol.
Note:
Do not use solvent, such as acetone, benzene, toluene and alcohol, as they
will cause the inverter surface paint to peel off.
Do not use detergent or alcohol to clean the display and other sections of the
control panel as these sections do not like them.
5.3.3 Periodic inspection
Check the areas inaccessible during operation and requiring periodic inspection.
(1) Cooling system: ......Clean the air filter, etc.
(2) Screws and bolts: ...These parts may become loose due to vibration, temperature
changes, etc. Check that they are tightened securely and
retighten as necessary.
(3) Conductors and insulating materials: Check for corrosion and damage.
(4) Insulation resistance: Measure.
(5) Cooling fan, smoothing capacitor: Check and change if necessary.

PROTECTIVE FUNCTIONS
(2) Smoothing capacitors
A large-capacity aluminum electrolytic capacitor is used for smoothing the DC in the
main circuit, and an aluminum electrolytic capacitor is also used for stabilizing the
control power in the control circuit.
Their characteristics are adversely affected by ripple current, etc. When the inverter is
operated in an ordinary, air-conditioned environment, change the capacitors about
every 5 years. When 5 years have elapsed, the capacitors will deteriorate more rapidly.
Check the capacitors at least every year (less than six months if the life will be expired
soon). Check the following:
1) Case (side faces and bottom face for expansion)
2) Sealing plate (for remarkable warp and extreme crack)
3) Appearance, external cracks, discoloration, leakage.
When the measured capacitance of the capacitor has reduced below 85% of the
rating, change the capacitor.
When you need to change the capacitors, contact the nearest Mitsubishi FA center.

5.3.7 Measurement of main circuit voltages, currents and powers
Measurement of voltages and currents
Since the voltages and currents on the inverter power supply and output sides include
harmonics, accurate measurement depends on the instruments used and circuits
measured.
When instruments for commercial frequency are used for measurement, measure the
following circuits using the instruments given on the next page.

varies with motor loss) when the motor alone is decelerated from 50Hz in
the shortest time and is not a continuous regenerative torque. When the
motor is decelerated from the frequency higher than the base frequency,
the average deceleration torque will reduce. Since the inverter does not
contain a brake resistor, use the optional brake resistor when regenerative
energy is large. A brake unit (BU) may also be used.
