in death or severe injury.
Assumes that incorrect handling may
cause hazardous conditions, resulting
in medium or slight injury, or may
cause physical damage only.
Note that even the level may lead to a serious
consequence according to conditions. Please follow the
instructions of both levels because they are important to
personnel safety.
While power is on or when the inverter is running, do not open
the front cover. Otherwise you may get an electric shock.
Do not run the inverter with the front cover or wiring cover
removed. Otherwise, you may access the exposed highvoltage terminals or the charging part of the circuitry and
get an electric shock.
Even 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, switch off power,
check to make sure that the operation panel indicator is off,
wait for at least 10 minutes after the power supply has been
switched off, and check that there are no residual voltage
using a tester or the like. The capacitor is charged with high
voltage for some time after power off and it is dangerous.
This inverter must be earthed (grounded). Earthing
(grounding) must conform to the requirements of national
and local safety regulations and electrical code. (NEC
section 250, IEC 536 class 1 and other applicable standards)
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.
Perform setting dial and key operations with dry hands to
prevent an electric shock. Otherwise you may get an electric
shock.
Do not subject the cables to scratches, excessive 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.
Do not touch the printed circuit board with wet hands.
Otherwise, you may get an electric shock.
When measuring the main circuit capacitor capacity, the
DC voltage is applied to the motor for 1s at powering off.
Never touch the motor terminal, etc. right after powering
off to prevent an electric shock.
WARNING
CAUTION
CAUTION
WARNING
Install the inverter on an incombustible wall without holes, etc.
Mounting it to or near combustible material can cause a fire.
If the inverter has become faulty, switch off the inverter
power. A continuous flow of large current could cause a fire.
When using a brake resistor, make up a sequence that will
turn off power when an alarm signal is output. Otherwise,
the brake resistor may excessively overheat due to
damage of the brake transistor and such, causing a fire.
Do not connect a resistor directly to the DC terminals P/+,
N/-. This could cause a fire.
Apply only the voltage specified in the instruction manual
to each terminal. Otherwise, burst, damage, etc. may occur.
Ensure that the cables are connected to the correct
terminals. Otherwise, burst, damage, etc. may occur.
Always make sure that polarity is correct to prevent
damage, etc. Otherwise, burst, damage, etc. may occur.
While power is on or for some time after power-off, do not
touch the inverter as they will be extremely hot. Doing so
can cause burns.
Transport the product using the correct method that
corresponds to the weight. Failure to observe this could
lead to injuries.
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 install or operate the inverter if it is damaged or
has parts missing.
When carrying the inverter, do not hold it by the front
cover; it may fall off or fail.
Do not stand or rest heavy objects on the product.
Check the inverter mounting orientation is correct.
Prevent other conductive bodies such as screws and
metal fragments or other flammable substance such as oil
from entering the inverter.
As the inverter is a precision instrument, do not drop or
subject it to impact.

(7) Disposal
Do not install a power factor correction capacitor or surge
suppressor/capacitor type filter on the inverter output
side.
The connection orientation of the output cables U, V, W to
the motor will affect the direction of rotation of the motor.
Before starting operation, confirm and adjust the
parameters. A failure to do so may cause some machines
to make unexpected motions.
When you have chosen the retry function, stay away from
the equipment as it will restart suddenly after an alarm
stop.
Since is valid only when functions are set (Refer to
page 74), provide a circuit and switch separately to make
an emergency stop (power off, mechanical brake
operation for emergency stop, etc).
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.
Do not perform parts removal which is not instructed in this
manual. Doing so may lead to fault or damage of the product.
The electronic thermal relay function does not guarantee
protection of the motor from overheating.
Do not use a magnetic contactor on the inverter input 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
supply harmonics from the inverter may heat/damage the
power factor correction capacitor and generator.
When parameter clear or all parameter clear is performed,
reset the required parameters before starting operations.
Each parameter returns to the initial value.
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.
For prevention of damage due to static electricity, touch
nearby metal before touching this product to eliminate
static electricity from your body.
CAUTION
CAUTION
WARNING
CAUTION
Provide a safety backup such as an emergency brake
which will prevent the machine and equipment from
hazardous conditions if the inverter fails.

2 INSTALLATION AND WIRING
Note
Do not install a power factor correction capacitor, surge suppressor or radio noise filter on the inverter output side.
This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices
are connected, immediately remove them.
Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency 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.
( Refer to the chapter 3 of the Instruction Manual (applied)).
Refer to the instruction manual of each option and peripheral devices for details of peripheral devices.
Three-phase AC power supply
Use within the permissible power
supply specifications of the inverter.
Magnetic contactor (MC)
Install the magnetic contactor to ensure
safety. Do not use this magnetic contactor
to start and stop the inverter. Doing so will
cause the inverter life to be shorten.
Noise filter
(FR-BSF01, FR-BLF)
Install a noise filter to reduce the
electromagnetic noise generated
from the inverter.
Effective in the range from about
1MHz to 10MHz. A wire should be
wound four turns at a maximum.

Reactor (FR-HAL, FR-HEL option)
Reactors (option) must be used when
power harmonics measures are taken,
the power factor is to be improved or the
inverter is installed near a large power
supply system (500kVA or more). The
inverter may be damaged if you do not
use reactors. Select the reactor according
to the model. Remove the jumpers across
terminals P/+ - P1 to connect the DC reactor.
Noise filter

Moulded case circuit breaker
(MCCB) or earth leakage current
breaker (ELB), fuse
The breaker must be selected carefully
since an in-rush current flows in the
inverter at power on.
Install a noise filter to reduce
the electromagnetic noise
generated from the inverter.
Effective in the range from
about 1MHz to 10MHz. When
more wires are passed
through, a more effective result
can be obtained. A wire should
be wound four turns or more.
To prevent an electric shock, always earth (ground)
the motor and inverter. For reduction of induction noise
from the power line of the inverter, it is recommended
to wire the earth (ground) cable by returning it to the
earth (ground) terminal of the inverter.

The life of the inverter is influenced by ambient
temperature. The ambient temperature should be
as low as possible within the permissible range.
This must be noted especially when the inverter
is installed in an enclosure.
(Refer to page 6)
Wrong wiring might lead to damage of the
inverter. The control signal lines must be kept
fully away from the main circuit to protect them
from noise. (Refer to page 7)

2.1 Peripheral devices
Check the inverter type of the inverter you purchased. Appropriate peripheral devices must be selected according to the
capacity.
Refer to the following list and prepare appropriate peripheral devices:
∗1 Select an MCCB according to the power supply capacity.
Install one MCCB per inverter.
∗2 When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to
the inverter type and cable and reactor according to the motor output.
∗3 When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter, etc. Identify the cause of
the trip, then remove the cause and power on the breaker.
∗4 For installations in the United States or Canada, use the class T type fuse certified by the UL and cUL. (Refer to page 121)

Wiring(1) Cable sizes etc., of the main control circuit terminals and earth (ground) terminals
Select the recommended cable size to ensure that a voltage drop will be 2% max.
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.
The following table indicates a selection example for the wiring length of 20m.
200V class (when input power supply is 220V)
∗1 The cable size is that of the cable (HIV cable (600V class 2 vinyl-insulated cable) etc.) with continuous maximum permissible temperature of 75°C. Assumes
that the ambient temperature is 50°C or less and the wiring distance is 20m or less.
∗2 The recommended cable size is that of the cable (THHW cable) with continuous maximum permissible temperature of 75°C. Assumes that the ambient
temperature is 40°C or less and the wiring distance is 20m or less.
(Selection example for use mainly in the United States.)
∗3 The recommended cable size is that of the cable (THHW cable) with continuous maximum permissible temperature of 70°C. Assumes that the ambient
temperature is 40°C or less and the wiring distance is 20m or less.
(Selection example for use mainly in Europe.)
∗4 The terminal screw size indicates the terminal size for R/L1, S/L2, T/L3, U, V, W, and a screw for earthing (grounding).
The line voltage drop can be calculated by the following formula:
line voltage drop [V]=
Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque
reduction) in the low speed range.

Note
Use the copper wires rated at 75°C.
Tighten the terminal screw to the specified torque. A screw that has been tighten too loosely can cause a short circuit
or malfunction. A screw that has been tighten too tightly can cause a short circuit or malfunction due to the unit
breakage.
Use crimping terminals with insulation sleeve to wire the power supply and motor.
Leakage currents flow in the inverter. To prevent an electric shock, the inverter and motor must be earthed (grounded). This
inverter must be earthed (grounded). Earthing (Grounding) must conform to the requirements of national and local safety
regulations and electrical codes. (NEC section 250, IEC 536 class 1 and other applicable standards)
Use the dedicated earth (ground) terminal to earth (ground) the inverter. (Do not use the screw in the casing, chassis, etc.)
Use the thickest possible earth (ground) cable. Use the cable whose size is equal to or greater than that indicated on page
9 , and minimize the cable length. The earthing (grounding) point should be as near as possible to the inverter.
POINT
To be compliant with the European Directive (Low Voltage Directive), earth (ground) the inverter according to the
instructions on page 119.

The input signals are set to sink logic (SINK) when shipped from the
factory.
To change the control logic, the jumper connector above the control
terminal must be moved to the other position.
To change to source logic, change the jumper connector in the sink
logic (SINK) position to source logic (SOURCE) position using
tweezers, a pair of long-nose pliers etc. Change the jumper
connector position before switching power on.
Note
Fully make sure that the front cover has been reinstalled securely.
The capacity plate is placed on the front cover and the rating plate is on the inverter. Since these plates have the
same serial numbers, always reinstall the removed cover onto the original inverter.
The sink-source logic change-over jumper connector must be fitted in only one of those positions. If it is fitted in both
positions at the same time, the inverter may be damaged. 14

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) Use two or more parallel micro-signal contacts or twin contacts to prevent
contact faults when using contact inputs since the control circuit input signals
are micro-currents.
4) Do not apply a voltage to the contact input terminals (e.g. STF) of the control
circuit.
5) Always apply a voltage to the alarm output terminals (A, B, C) via a relay coil, lamp, etc.
6) It is recommended to use the cables of 0.3mm2 to 0.75mm2 gauge for connection to the control circuit terminals.
If the cable gauge used is 1.25mm2 or more, the front cover may be lifted when there are many cables running or the
cables are run improperly, resulting in an operation panel contact fault.
7) The maximum wiring length should be 30m (200m for terminal FM).

When using the brake resistor (MRS, MYS, FR-ABR)
2.5 When using the brake resistor (MRS, MYS, FR-ABR)
It is recommended to configure a sequence, which shuts off power in the input side of the inverter by the external thermal
relay as shown below, to prevent overheat and burnout of the brake resistor (MRS, MYS) and high duty brake resistor (FRABR) in case the regenerative brake transistor is damaged. (The brake resistor can not be connected to the 0.1K or 0.2K.)

Power-off and magnetic contactor (MC)
2.6 Power-off and magnetic contactor (MC)
(1) Inverter input side magnetic contactor (MC)
On the inverter input side, it is recommended to provide an MC for the following purposes.
(Refer to page 3 for selection.)
1) To release the inverter from the power supply when the inverter's protective function is activated or when the drive is not
functioning (e.g. emergency stop operation). When cycle operation or heavy-duty operation is performed with an optional
brake resistor connected, overheat and burnout of the discharging resistor can be prevented if a regenerative brake
transistor is damaged due to insufficient heat capacity of the discharging resistor and excess regenerative brake duty.
2) To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power failure
3) The control power supply for inverter is always running and consumes a little power. When stopping the inverter for an
extended period of time, powering off the inverter will save power slightly.
4) To separate the inverter from the power supply to ensure safe maintenance and inspection work.
The inverter's input side MC is used for the above purpose, select class JEM1038-AC3 MC for the inverter input side
current when making an emergency stop during normal operation.
(2) Handling of inverter output side magnetic contactor
Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop. When the
magnetic contactor is turned on while the inverter is operating, overcurrent protection of the inverter and such will activate.
When an MC is provided for switching to the commercial power supply, for example, switch it on/off after the inverter and
motor have stopped.
REMARKS
Since repeated inrush currents at power on will shorten the life of the converter circuit (switching life is about 1,000,000 times.),
frequent starts and stops of the MC must be avoided. Turn on/off the inverter start controlling terminals (STF, STR) to run/stop the
inverter.
Inverter start/stop circuit example
As shown on the right, always use the start signal
(ON or OFF across terminals STF or STR-SD) to
make a start or stop.

Precautions for use of the inverter2.7 Precautions for use of the inverter
The FR-E700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may
shorten the product life or damage the product.
Before starting operation, always recheck the following items.
(1) Use crimping terminals with insulation sleeve to wire the power supply and motor.
(2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring.
(3) After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.
When drilling mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the
inverter.
(4) Use cables of the size to make a voltage drop 2% maximum.
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.
Refer to page 9 for the recommended wire sizes.
(5) The overall wiring length should be 500m maximum.
Especially for long distance wiring, the fast-response current limit function may decrease or the equipment connected to
the secondary side may malfunction or become faulty under the influence of a charging current due to the stray capacity
of the wiring. Therefore, note the overall wiring length. (Refer to page 10)
(6) Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency 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.
(7) Do not install a power factor correction capacitor, surge suppressor or radio noise filter on the inverter output side.
This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are
connected, immediately remove them.
(8) Before starting wiring or other work after the inverter is operated, wait for at least 10 minutes after the power supply has
been switched off, and check that there are no residual voltage using a tester or the like. The capacitor is charged with
high voltage for some time after power off and it is dangerous.
(9) A short circuit or earth (ground) fault on the inverter output side may damage the inverter modules.
Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits caused by
peripheral circuit inadequacy or an earth (ground) fault caused by wiring inadequacy or reduced motor insulation
resistance may damage the inverter modules.
Fully check the to-earth (ground) insulation and phase to phase insulation of the inverter output side before power-on.
Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance etc.
(10) Do not use the inverter input side magnetic contactor to start/stop the inverter.
Always use the start signal (turn on/off terminals STF, STR-SD) to start/stop the inverter. (Refer to page 20)
(11) Across P/+ and PR terminals, connect only an external regenerative brake discharge resistor.
Do not connect a mechanical brake.
The brake resistor can not be connected to the 0.1K or 0.2K. Leave terminals P/+ and PR open.
Also, never short between these terminals.21
Precautions for use of the inverter(12) Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.
Application of a voltage higher than the permissible voltage to the inverter I/O signal circuits or opposite polarity may
damage the I/O devices. Especially check the wiring to prevent the speed setting potentiometer from being connected
incorrectly to short terminals 10-5.
(14) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in the
inverter's input side 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.
(15) Instructions for overload operation
When performing operation of frequent start/stop of the inverter, rise/fall in the temperature of the transistor element of
the inverter will repeat due to a repeated flow of large current, shortening the life from thermal fatigue. Since thermal
fatigue is related to the amount of current, the life can be increased by reducing current at locked condition, starting
current, etc. Decreasing current may increase the life. However, decreasing current will result in insufficient torque and
the inverter may not start. Therefore, choose the inverter which has enough allowance for current (up to 2 rank larger in
capacity).
(16) Make sure that the specifications and rating match the system requirements.
(13) Provide electrical and mechanical interlocks for MC1 and MC2
which are used for bypass operation. When the wiring is
incorrect and if there is a bypass operation circuit as shown
right, the inverter will be damaged when the power supply is
connected to the inverter U, V, W terminals, due to arcs
generated at the time of switch-over or chattering caused by a
sequence error.

Failsafe of the system which uses the inverter
2.8 Failsafe of the system which uses the inverter
When a fault occurs, the inverter trips to output an alarm. However, an alarm output signal may not be output at an inverter
alarm occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures best quality products,
provide an interlock which uses inverter status output signals to prevent accidents such as damage to machine when the
inverter fails for some reason and at the same time consider the system configuration where failsafe from outside the inverter,
without using the inverter, is enabled even if the inverter fails.
(1) Interlock method which uses the inverter status output signals
By combining the inverter status output signals to provide an interlock as shown below, an inverter alarm can be
detected.
(2) Backup method outside the inverter
Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure
status of the inverter iteself. For example, even if the interlock is provided using the inverter alarm output signal, start
signal and RUN signal putput, there is a case where an alarm output signal is not output and RUN signal is kept output
even if an inverter alarm occurs.
Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider the
backup system such as cheking up as below according to the level of importance of the system.
1) Start signal and actual operation check
Check the motor running and motor current while the start signal is input to the inverter by comparing the start signal to
the inverter and detected speed of the speed detector or detected current of the current detector. Note that the motor
current runs as the motor is running for the period until the motor stops since the inverter starts decelerating even if the
start signal turns off. For the logic check, configure a sequence considering the inverter deceleration time. In addition, it is
recommended to check the three-phase current when using the current detector.
2) Command speed and actual operation check
Check if there is no gap between the actual speed and commanded speed by comparing the inverter speed command
and detected speed of the speed detector.

Advanced magnetic flux vector control, general-purpose magnetic flux vector control?
The low speed torque can be improved by providing voltage compensation so that the motor current which meets the
load torque to flow. Output frequency compensation (slip compensation) is made so that the motor actual speed
approximates a speed command value. Effective when load fluctuates drastically, etc.
General-purpose magnetic flux vector control is the same function as it is for the FR-E500 series. Select this control

3.3.9 To exhibit the best performance of the motor performance (offline auto tuning)
(Pr. 71, Pr. 83, Pr. 84, Pr. 96)
The motor performance can be maximized with offline auto tuning.
What is offline auto tuning?
When performing advanced magnetic flux vector control or general-purpose magnetic flux vector control, the motor
can be run with the optimum operating characteristics by automatically measuring the motor constants (offline auto
tuning) even when each motor constants differs, other manufacturer's motor is used, or the wiring length is long.

POINT
This function is made valid only when a value other than "9999" is set in Pr. 80 and Pr. 81 and advanced
magnetic flux vector control or general-purpose magnetic flux vector control is selected.
You can copy the offline auto tuning data (motor constants) to another inverter with the PU (FR-PU07).
Even when motors (other manufacturer's motor, SF-JRC, etc.) other than Mitsubishi standard motor, high
efficiency motor (SF-JR, SF-HR 0.2kW or more), and Mitsubishi constant-torque motor (SF-JRCA SF-HRCA
four-pole 0.4kW to 15kW) are used or the wiring length is long, using the offline auto tuning function runs the
motor with the optimum operating characteristics.
Tuning is enabled even when a load is connected to the motor.
As the motor may run slightly, fix the motor securely with a mechanical brake or make sure that there will be no
problem in safety if the motor runs (caution is required especially in elevator). Note that tuning performance is
unaffected even if the motor runs slightly.
Reading/writing/copy of motor constants tuned by offline auto tuning are enabled.
The offline auto tuning status can be monitored with the operation panel and PU (FR-PU04/FR-PU07).43
Before operation(1) Before performing offline auto tuning
Check the following before performing offline auto tuning.
Make sure advanced magnetic flux vector control or general-purpose magnetic flux vector control (Pr. 80, Pr. 81) is
selected. (Tuning can be performed even under V/F control selected by turning on X18.)
A motor should be connected. Note that the motor should be at a stop at a tuning start.
The motor capacity should be equal to or one rank lower than the inverter capacity. (note that the capacity should be
0.1kW or more)
The maximum frequency is 120Hz.
A high-slip motor, high-speed motor and special motor cannot be tuned.
As the motor may run slightly, fix the motor securely with a mechanical brake or make sure that there will be no problem in
safety if the motor runs (caution is required especially in elevator). Note that tuning performance is unaffected even if the
motor runs slightly.
(2) Setting
1) Select advanced magnetic flux vector control or general-purpose magnetic flux vector control. (Refer to page 40)
2) Set "1" or "11" in Pr. 96 Auto tuning setting/status.
When the setting is "1" ....... Tune all motor constants without running the motor.
When performing advanced magnetic flux vector control, set "1" to perform tuning.
It takes approximately 25 to 75s∗ until tuning is completed.
(Excitation noise is produced during tuning.)
∗Tuning time differs according to the inverter capacity and motor type.
When the setting is "11" ...... Tune motor constants (R1) only without running the motor.
When performing general-purpose magnetic flux vector control, set "11" to perform tuning.
It takes approximately 9s until tuning is completed.
3) Set the rated motor current (initial value is rated inverter current) in Pr. 9 Electronic thermal O/L relay. (Refer to page 34)
4) Set the rated voltage of motor (initial value is 200V) in Pr. 83 Rated motor voltage and rated motor frequency (initial value is
60Hz) in Pr. 84 Rated motor frequency.
(For a Japanese standard motor, etc. which has both 50Hz and 60Hz rated values, use it with an initial value (200V/
60Hz).
5) Set Pr. 71 Applied motor according to the motor used.

(3) Execution of tuning
1) When performing tuning or PU operation, press of the operation panel or or of the parameter unit
(FR-PU04/FR-DU07).
For external operation, turn on the run command (STF signal or STR signal). Tuning starts.
2) Monitor is displayed on the operation panel and parameter unit (FR-PU04/FR-PU07) during tuning as below.
POINT
Before performing tuning, check the monitor display of the operation panel or parameter unit (FR-PU04/FR-PU07)
if the inverter is in the status for tuning. (Refer to 2) below) When the start command is turned on under V/F
control, the motor starts.
Note
To force tuning to end, use the MRS or RES signal or press of the operation panel. (Turning the start signal (STF
signal or STR signal) off also ends tuning.)
During offline auto tuning, only the following I/O signals are valid: (initial value)
Input terminal MRS, RES, STF, STR
Output terminal RUN, FM, A, B, C
Note that the progress status of offline auto tuning is output from FM when speed and output frequency are selected.
Since the RUN signal turns on when tuning is started, caution is required especially when a sequerence which
releases a mechanical brake by the RUN signal has been designed.
When executing offline auto tuning, input the run command after switching on the main circuit power (R/L1, S/L2, T/
L3) of the inverter.
Do not perform ON/OFF switching of the second function selection signal (RT) during execution of offline auto
tuning. Auto tuning is not excecuted properly.

Before operation3) When offline auto tuning ends, press of the operation panel during PU operation. For external operation, turn off
the start signal (STF signal or STR signal) once.
This operation resets the offline auto tuning and the PU's monitor display returns to the normal indication.
(Without this operation, next operation cannot be started.)
4) If offline auto tuning ended in error (see the table below), motor constants are not set.
Perform an inverter reset and restart tuning.
5) When tuning is ended forcibly by pressing or turning off the start signal (STF or STR) during tuning, offline auto
tuning does not end normally. (The motor constants have not been set.)
Perform an inverter reset and restart tuning.
REMARKS
Do not change the Pr. 96 setting after completion of tuning (3 or 13).
If the Pr. 96 setting is changed, tuning data is made invalid.
If the Pr. 96 setting is changed, tuning must be performed again.

Calculation error
A motor is not connected.
Check the motor wiring and make setting again.
Note
The motor constants measured once in the offline auto tuning are stored as parameters and their data are held until
the offline auto tuning is performed again.
An instantaneous power failure occurring during tuning will result in a tuning error.
After power is restored, the inverter goes into the normal operation mode. Therefore, when STF (STR) signal is on,
the motor runs in the forward (reverse) rotation.
Any alarm occurring during tuning is handled as in the ordinary mode. Note that if an error retry has been set, retry is
ignored.
CAUTION
As the motor may run slightly during offline auto tuning, fix the motor securely with a mechanical brake or make sure
that there will be no problem in safety if the motor runs. Note that if the motor runs slightly, tuning performance is
unaffected.46

6. To check the setting, turn the start switch (STF
or STR) on and input 5V (turn the
potentiometer clockwise slowly to full). (Refer
to operation 2 to 5 of the section 3.5.3)
REMARKS
To change the value to more than 120Hz, the maximum frequency must be set to more than 120Hz.
The frequency meter (indicator) connected to across terminals FM-SD does not indicate just 50Hz ... Why?
The frequency meter can be adjusted using calibration parameter C0 FM terminal calibration. ( Refer to the chapter 4 of
the Instruction Manual (applied)).
Use calibration parameter C2 to set frequency at 0V and
calibration parameter C0 to adjust the indicator.
( Refer to the chapter 4 of the Instruction Manual (applied)).
As other adjustment methods of frequency setting voltage gain, there are methods to adjust with a voltage applied to across
terminals 2-5 and adjust at any point without a voltage applied. ( Refer to the Instruction Manual (applied) for the setting
method of calibration parameter C4.)

129 PID proportional
band
0.1% 100%
0.1 to
1000%
If the proportional band is narrow
(parameter setting is small), the
manipulated variable varies greatly with a
slight change of the measured value.
Hence, as the proportional band narrows,
the response sensitivity (gain) improves
but the stability deteriorates, e.g. hunting
occurs. Gain Kp= 1/proportional band
9999 No proportional control
130 PID integral time 0.1s 1s
0.1 to
3600s
Time required for the integral (I) action to
provide the same manipulated variable as
that for the proportional (P) action. As the
integral time decreases, the set point is
reached earlier but hunting occurs more
easily.
9999 No integral control.
131 PID upper limit 0.1% 9999 0 to 100%
Set the upper limit value. If the feedback
value exceeds the setting, the FUP signal
is output. The maximum input (20mA/5V/
10V) of the measured value (terminal 4) is
equivalent to 100%.
9999 No function
132 PID lower limit 0.1% 9999 0 to 100%
Set the lower limit value. If the measured
value falls below the setting range, the
FDN signal is output. The maximum input
(20mA/5V/10V) of the measured value
(terminal 4) is equivalent to 100%.
9999 No function

Time required for only the differential (D)
action to provide the same manipulated
variable as that for the proportional (P)
action. As the differential time increases,
greater response is made to a deviation
change.
9999 No differential control.

Reset method of protective function4 TROUBLESHOOTING
When a fault occurs in the inverter, the inverter trips and the PU display automatically changes to any of the following error
(alarm) indications.
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 fault output signal...When the magnetic contactor (MC) provided on the input side of the inverter is opened
when a fault occurs, the inverter's control power will be lost and the fault output will not be
held.
Fault or alarm indication ..........When the protective function is activated, the operation panel display automatically switches
to the indication.
Resetting method ....................When a fault occurs, the inverter output is kept stopped. Unless reset, therefore, the inverter
cannot restart. (Refer to page 88)
When any fault occurs, take the appropriate corrective action, then reset the inverter, and resume operation.
Not doing so may lead to the inverter fault and damage.
Inverter fault or alarm indications are roughly divided as below.
(1) Error Message
A message regarding operational fault and setting fault by the operation panel and parameter unit (FR-PU04 /FR-PU07)
is displayed. The inverter does not shut off output.
(2) Warnings
The inverter does not shut off output even when a warning is displayed. However, failure to take appropriate measures
will lead to a fault.
(3) Alarm
The inverter does not shut off output. You can also output an alarm signal by making parameter setting.
(4) Fault
When a fault occurs, the inverter trips and an alarm is output.
4.1 Reset method of protective function
(1) Resetting the inverter
The inverter can be reset by performing any of the following operations. Note that the internal thermal integrated value of the
electronic thermal relay function and the number of retries are cleared (erased) by resetting the inverter.
Recover about 1s after reset is cancelled.
Operation 1: ...... Using the operation panel, press to reset the inverter.
(This may only be performed when a fault occurs (Refer to page 93 for
fault.)
Operation 2: ....... Switch power off once, then switch it on again.
Operation 3: . ..... Turn on the reset signal (RES) for more than 0.1s. (If the RES signal
is kept on, "Err." appears (flickers) to indicate that the inverter is in a
reset status.)

When the main circuit capacitor life is measured under the following conditions, "forced end" (Pr. 259 = "8") or "measuring error"
(Pr. 259 = "9") occurs or it remains in "measuring start" (Pr. 259 = "1"). Therefore, do not measure in such case. In addition, even
when "measurement completion" (Pr. 259 = "3") is confirmed under the following conditions, normal measurement can not be
done.
(a)FR-HC, FR-CV, or FR-BU2 is connected.
(b)DC power supply is connected to terminal P/+ and N/-.
(c)Switch power on during measuring.
(d)The motor is not connected to the inverter.
(e)The motor is running (coasting).
(f)The motor capacity is two rank smaller as compared to the inverter capacity.
(g)The inverter is at an alarm stop or an alarm occurred while power is off.
(h)The inverter output is shut off with the MRS signal.
(i)The start command is given while measuring.
(j)The parameter unit (FR-PU04/FR-PU07) is connected.
(k)Using terminal PC as power supply.
(l) I/O terminal of the control terminal block and plug-in option is on (continuity).
(m)Plug-in option is fitted. (Only for the 0.75K or less)
POINT
For the accurate life measuring of the main circuit capacitor, perform after more than 3 hrs passed since the turn
off of the power as it is affected by the capacitor temperature.
WARNING
When measuring the main circuit capacitor capacity (Pr. 259 Main circuit capacitor life measuring = "1"), the DC voltage is
applied to the motor for 1s at powering off. Never touch the motor terminal, etc. right after powering off to prevent an
electric shock.
Note
Do not use solvent, such as acetone, benzene, toluene and alcohol, as they will cause the inverter surface paint to peel
off.
The display, etc. of the operation panel and parameter unit (FR-PU04/FR-PU07) are vulnerable to detergent and alcohol.
Therefore, avoid using them for cleaning.107
Inspection items5.1.6 Replacement of parts
The inverter consists of many electronic parts such as semiconductor devices.
The following parts may deteriorate with age because of their structures or physical characteristics, leading to reduced
performance or fault of the inverter. For preventive maintenance, the parts must be replaced periodically.
Use the life check function as a guidance of parts replacement.
∗1 Replacement years for when the yearly average ambient temperature is 40°C
(without corrosive gas, flammable gas, oil mist, dust and dirt etc.)
∗2 Output current: equivalent to rating current of the Mitsubishi standard motor (4 poles)
(1) Cooling fan
The replacement interval of the cooling fan used for cooling the parts generating heat such as the main circuit semiconductor
is greatly affected by the ambient temperature. When unusual noise and/or vibration is noticed during inspection, the cooling
fan must be replaced immediately.

Note
Installing the fan in the opposite air flow direction can cause the inverter life to be shorter.
Prevent the cable from being caught when installing a fan.
Switch the power off before replacing fans. Since the inverter circuits are charged with voltage even after
power off, replace fans only when the inverter cover is on the inverter to prevent an electric shock
accident.110

Inspection items(2) Smoothing capacitors
A large-capacity aluminum electrolytic capacitor is used for smoothing in the main circuit DC section, and an aluminum
electrolytic capacitor is used for stabilizing the control power in the control circuit. Their characteristics are deteriorated by the
adverse effects of ripple currents, etc. The replacement intervals greatly vary with the ambient temperature and operating
conditions. When the inverter is operated in air-conditioned, normal environment conditions, replace the capacitors about
every 10 years.
When a certain period of time has 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).
The appearance criteria for inspection are as follows:
1) Case: Check the side and bottom faces for expansion
2) Sealing plate: Check for remarkable warp and extreme crack.
3) Check for external crack, discoloration, liquid leakage, etc. Judge that the capacitor has reached its life when the
measured capacitance of the capacitor reduced below 80% of the rating.
(3) Relays
To prevent a contact fault, etc., relays must be replaced according to the cumulative number of switching times (switching life).
5.1.7 Inverter replacement
The inverter can be replaced with the control circuit wiring kept connected. Before replacement, remove the wiring cover of
the inverter.
(1) Remove the installation screw of the control circuit terminal block.
Pull the control circuit terminal downward.
(2) Using care not to bend the pins of the inverter's control circuit connector, reinstall the control circuit terminal block and fix
it with the installation screw.
POINT
Refer to page 107 to perform the life check of the main circuit capacitor.
Note
Before starting inverter replacement, switch power off, wait for at least 10 minutes, and then check the voltage with a
tester and such to ensure safety.

(1) EMC Directive
1) Our view of transistorized inverters for the EMC Directive
A transistorized inverter is a component designed for installation in an enclosure 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. (The CE mark is placed on inverters
in accordance with the Low Voltage Directive.) CEMEP
2) Compliance
We understand that the general-purpose inverters are not covered directly by the EMC Directive. However, the EMC
Directive applies to machines/equipment into which inverters have been incorporated, and these machines and equipment
must carry the CE marks. EMC Installation Guidelines BCN-A21041-202
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.
(2) Low Voltage Directive
We have self-confirmed our inverters as products compliant to the Low Voltage Directive (Conforming standard EN 50178)
and place the CE mark on the inverters.
Outline of instructions
∗ Do not use an earth leakage breaker as an electric shock protector without connecting the equipment to the earth.
Connect the equipment to the earth securely.
∗ Wire the earth (ground) terminal independently. (Do not connect two or more cables to one terminal.)
∗ Use the cable sizes on page 9 under the following conditions.
Ambient Temperature: 40°C maximum
If conditions are different from above, select appropriate wire according to EN60204 ANNEX C TABLE 5.
∗ When tightening the screw, be careful not to damage the threads.
For use as a product compliant with the Low Voltage Directive, use PVC cable on page 9.
∗ Use the moulded case circuit breaker and magnetic contactor which conform to the EN or IEC Standard.
∗ When using an earth leakage current breaker, use a residual current operated protective device (RCD) of type B
(breaker which can detect both AC and DC). If not, provide double or reinforced insulation between the inverter and other
equipment, or put a transformer between the main power supply and inverter.
∗Use the inverter under the conditions of overvoltage category II (usable regardless of the earth (ground) condition of the
power supply) specified in IEC664.
To use the inverter under the conditions of pollution degree 3, install it in the enclosure of IP54 or higher.
Appendix2 Instructions for Compliance with the European Directives119
To use the inverter of 7.5K or less (IP20) outside of an enclosure in the environment of pollution degree 2, fix a fan cover
with fan cover fixing screws enclosed.
∗EN60204C
∗The operating capacity of the relay outputs (terminal symbols A, B, C) should be 30VDC, 0.3A. (Relay outputs are
basically isolated from the inverter internal circuit.)
∗Control circuit terminals on page7are safely isolated from the main circuit.

1. General Precaution
The bus capacitor discharge time is 10 minutes. Before starting wiring or inspection, switch power off, wait for more than 10 minutes,
and check for residual voltage between terminal P/+ and N/- with a meter etc., to avoid a hazard of electrical shock.
2. Installation
The below types of inverter have been approved as products for use in enclosure and approval tests were conducted under the
following conditions. Design the enclosure so that the ambient temperature, humidity and ambience of the inverter will satisfy the
above specifications.
Wiring protection
For installation in the United States, branch circuit protection must be provided in accordance with the National Electrical Code and
any applicable provincial codes.
For installation in Canada, branch circuit protection must be provided in accordance with the Canadian Electrical Code and any
applicable provincial codes.
Provide the appropriate UL and cUL listed Class T type fuse that is suitable for branch circuit protection in accordance with the table
below.
∗ Maximum allowable rating by US National Electrical Code.Exact size must be chosen for each installation.
3. Short circuit ratings
Suitable For Use in A Circuit Capable of Delivering Not More Than 100 kA rms Symmetrical Amperes, 264 V Maximum.
4. Wiring
⋅ The cables used should be 75°C copper cables.
⋅ Tighten the terminal screws to the specified torques.
Undertightening can cause a short or misoperation.
Overtightening can cause the screws and unit to be damaged, resulting in a short or misoperation.
⋅ Use the UL approved round crimping terminals. Crimp the terminals with the crimping tool recommended by the terminal manufacturer.
5. Motor overload protection
When using the electronic thermal relay function as motor overload protection, set the rated motor current to Pr. 9 "Electronic thermal
O/L relay".

This function detects the overload (overheat)
of the motor, stops the operation of the
inverter's output transistor, and stops the
output.
(The operation characteristic is shown on the
left)
When using the Mitsubishi constant-torque
motor
1) Set "1" or any of "13" to "16", "50", "53", "54"
in Pr. 71. (This provides a 100% continuous
torque characteristic in the low-speed range.)
2) Set the rated current of the motor in Pr. 9.
∗1 When a value 50% of the inverter rated output
current (current value) is set in Pr. 9
∗2 The % value denotes the percentage to the
inverter rated output current. It is not the
percentage to the motor rated current.
∗3 When you set the electronic thermal relay
function dedicated to the Mitsubishi constanttorque motor, this characteristic curve applies
to operation at 6Hz or higher.
Note
⋅ Protective function by electronic thermal relay function is reset by inverter power reset and reset signal input. Avoid unnecessary reset and power-off.
⋅ When multiple motors are operated by a single inverter, protection cannot be provided by the electronic thermal relay function.
Install an external thermal relay to each motor.
⋅ When the difference between the inverter and motor capacities is large and the setting is small, the protective characteristics
of the electronic thermal relay function will be deteriorated. In this case, use an external thermal relay.
⋅ A special motor cannot be protected by the electronic thermal relay function. Use the external thermal relay.
