This Instruction Manual (basic) provides handling information and precautions for use of the equipment.
Please forward this Instruction Manual (basic) to the end user.
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the
inverter until you have read through the Instruction Manual
(basic) and appended documents carefully and can use the
equipment correctly. Do not use this product until you have
a full knowledge of the equipment, safety information and
instructions.
In this Instruction Manual (basic), the safety instruction
levels are classified into "WARNING" and "CAUTION".
WARNING
Incorrect handling may cause
hazardous conditions, resulting in
death or severe injury.
CAUTION
Incorrect handling may cause
hazardous conditions, resulting in
medium or slight injury, or may cause
only material damage.
The CAUTION
level may even lead to a serious
consequence according to conditions. Both instruction
levels must be followed because these are important to
personal safety.
1. Electric Shock Prevention
WARNING
z While power is ON or when the inverter is running, do not
open the front cover. Otherwise you may get an electric
shock.
z 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.
z 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.
z Before wiring or inspection, power must be switched OFF. To
confirm that, LED indication of the operation panel must be
checked. (It must be OFF.) Any person who is involved in
wiring or inspection shall 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.
z 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).
A neutral-point earthed (grounded) power supply for 400V
class inverter in compliance with EN standard must be used.
z Any person who is involved in wiring or inspection of this
equipment shall be fully competent to do the work.
z The inverter must be installed before wiring. Otherwise you
may get an electric shock or be injured.
z Setting dial and key operations must be performed with dry
hands to prevent an electric shock. Otherwise you may get
an electric shock.
z Do not subject the cables to scratches, excessive stress,
heavy loads or pinching. Otherwise you may get an electric
shock.
z Do not change the cooling fan while power is ON. It is
dangerous to change the cooling fan while power is ON.
z Do not touch the printed circuit board with wet hands.
Otherwise you may get an electric shock.
z 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.
2. Fire Prevention
CAUTION
z Inverter must be installed on a nonflammable wall without
holes (so that nobody touches the inverter heatsink on the
rear side, etc.). Mounting it to or near flammable material
can cause a fire.
z If the inverter has become faulty, the inverter power must
be switched OFF. A continuous flow of large current could
cause a fire.
z When using a brake resistor, a sequence that will turn OFF
power when a fault signal is output must be configured.
Otherwise the brake resistor may excessively overheat
due to damage of the brake transistor and such, causing a
fire.
z Do not connect a resistor directly to the DC terminals P/+
and N/-. Doing so could cause a fire.

Install this as required.
Devices connected to the output Earth (Ground)
Do not install a power factor correction capacitor,
surge suppressor or capacitor type filter on the output
side of the inverter. When installing a moulded case
circuit breaker on the output side of the inverter,
contact each manufacturer for selection of the
moulded case circuit breaker.
Earth (Ground)
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.
NOTE
The life of the inverter is influenced by surrounding air temperature. The surrounding air 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 7)
y 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 9)
Do not install a power factor correction capacitor, surge suppressor or capacitor type 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 options among the capacitor type
EMC filter FR-BIF (for use in the input side only), the ferrite core type EMC filter FR-BSF01/FR-BLF, filterpack, and EMC
filter to minimize the 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.

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 surrounding air 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 surrounding air
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 surrounding air
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).
A screw for earthing (grounding) of the FR-E720-15K(SC) is indicated in ( ).
For single-phase power input, the terminal screw size indicates the size of terminal screw for R/L1, S/L2, U, V, W, PR, P/+, N/-, P1 and a screw for earthing
(grounding).
NOTE
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.
The line voltage drop can be calculated by the following formula:
3 × wire resistance[mΩ/m] × wiring distance[m] × current[A]
1000
Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque
line voltage drop [V]=
reduction) in the low speed range.
(2)
Earthing (Grounding) precautions
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 an neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard.
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
14 , and minimize the cable length. The earthing (grounding) point should be as near as possible to the inverter.
POINT
To be compliant with the EU Directive (Low Voltage Directive), earth (ground) the inverter according to the
instructions on page 141.

When driving a 400V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the
motor terminals, deteriorating the insulation of the motor. Take the following measures 1) or 2) in this case.
1) Use a "400V class inverter-driven insulation-enhanced motor" and set frequency in Pr. 72 PWM frequency selection
according to wiring length
50m or less
Carrier frequency
14.5kHz or less
Wiring Length

2) Connect the surge voltage suppression filter (FR-ASF-H/FR-BMF-H) on the inverter output side.
NOTE
Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray
capacitances of the wiring, leading to a malfunction of the overcurrent protective function, fast response current limit
function, or stall prevention function or a malfunction or fault of the equipment connected on the inverter output side.
If malfunction of fast-response current limit function occurs, disable this function. If malfunction of stall prevention
function occurs, increase the stall level. (

Changing the control logic
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.
Terminal PC is always the common terminal for the safety stop input terminals (S1 and S2) of the inverter with safety
stop function regardless of sink/source logic.

In sink logic, a signal switches ON when a current flows from the corresponding signal input terminal.
Terminal SD is common to the contact input signals. Terminal SE is common to the open collector output signals.
In source logic, a signal switches ON when a current flows into the corresponding signal input terminal.

Control circuit common terminals (SD, 5, SE)
Terminals SD, SE and 5 are common terminals for I/O signals.(All common terminals are isolated from each other.) Do not
earth them. Avoid connecting the terminal SD and 5 and the terminal SE and 5.
Terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM, RL, MRS, RES) and frequency output
signal (FM). The open collector circuit is isolated from the internal control circuit by photocoupler
Terminal 5 is a common terminal for the frequency setting signals (terminal 2 or 4). It should be protected from external noise
using a shielded or twisted wire.
Terminal SE is a common terminal for the open collector output terminal (RUN, FU). The contact input circuit is isolated from
the internal control circuit by photocoupler.
(4)
Signal inputs by contactless switches

Wiring instructions
1) It is recommended to use the wires of 0.3mm2 to 0.75mm2 gauge for connection to the control circuit terminals.
2) The maximum wiring length should be 30m (200m for terminal FM).
3) Do not short terminal PC and SD. Inverter may be damaged.
4) 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.
5) Use shielded or twisted wires for connection to the control circuit terminals and
run them away from the main and power circuits (including the 200V relay
sequence circuit).

Power-OFF and magnetic contactor (MC)
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 fault occurs or when the drive is not functioning (e.g. emergency
stop operation). For example, MC avoids overheat or burnout of the brake resistor when heat capacity of the resistor is
insufficient or brake regenerative transistor is damaged with short while connecting an optional brake resistor.
2) To prevent any accident due to an automatic restart at restoration of power after an inverter stop by a power failure
3) While the power is ON, inverter is consuming a little power even during inverter stop. 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.
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 magnetic contactor must be avoided. Turn ON/OFF the inverter start controlling terminals (STF,
STR) to run/stop the inverter.

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.

Precautions for use of the inverter
2.7
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 points.
(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 14 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 16)
(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 options among the capacitor type
EMC filter FR-BIF (for use in the input side only), the ferrite core type EMC filter FR-BSF01/FR-BLF, filterpack, and EMC
filter to minimize the interference.
(8) For some short time after the power is switched OFF, a high voltage remains in the smoothing capacitor. When
accessing the inverter for inspection, wait for at least 10 minutes after the power supply has been switched OFF, and
then make sure that the voltage across the main circuit terminals P/+ and N/- of the inverter is not more than 30VDC
using a tester, etc. 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 of STF, STR signal) to start/stop the inverter. (Refer to page 32)
(11) Across terminals P/+ and PR, connect only an external regenerative brake discharging resistor.
Do not connect a mechanical brake.
The brake resistor can not be connected to the 0.1K(SC) or 0.2K(SC). Leave terminals P/+ and PR open.
Also, never short between these terminals.
33
2
INSTALLATION AND WIRING
(7) Do not install a power factor correction capacitor, surge suppressor or capacitor type 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. (When using capacitor type filter (FR-BIF) for single-phase power input model,
make sure of secure insulation of T/L3-phase, and connect to the input side of the inverter.)
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.
(13) Provide electrical and mechanical interlocks for MC1 and MC2
MC1
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

sequence error.
(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.
(17) When the motor speed is unstable, due to change in the frequency setting signal caused by electromagnetic noises from
the inverter, take the following measures while applying the motor speed by the analog signal.
y Do not run the signal cables and power cables (inverter I/O cables) in parallel with each other and do not bundle them.
y Run signal cables as far away as possible from power cables (inverter I/O cables).
y Use shield cables as signal cables.
y Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).

When a fault occurs, the inverter trips to output a fault signal. However, a fault output signal may not be output at an inverter
fault 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.

Refer to the chapter
4 of the Instruction
Manual (applied).
(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 itself. For example, when the inverter CPU fails, even if the interlock is provided using the inverter
fault output signal, start signal and RUN signal output, there is a case where a fault output signal is not output and RUN
signal is kept output even if an inverter fault 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 checking 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
2
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.

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 two or more motors are connected to the inverter, they cannot be protected 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 an external thermal relay.

Exhibiting the best performance for the motor (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 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 four-pole,
SF-HRCA 0.2kW 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).
Do not connect a surge voltage suppression filter (FR-ASF-H/FR-BMF-H) between the inverter and motor.

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)
A high-slip motor, high-speed motor and special motor cannot be tuned. (The maximum frequency is 120Hz.)
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.
Offline auto tuning will not be performed properly if it is performed with a surge voltage suppression filter (FR-ASF-H/FRBMF-H) connected between the inverter and motor. Remove it before starting tuning.
(2)
Setting
1) Select Advanced magnetic flux vector control or General-purpose magnetic flux vector control. (Refer to page 53)
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 46)
4) Set the rated voltage of motor (initial value is 200V/400V) 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
or 400V/60Hz).

Execution of tuning
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.
1) When performing tuning or PU operation, press
of the operation panel or
or
of the parameter unit
(FR-PU04/FR-PU07).
For external operation, turn ON the run command (STF signal or STR signal). Tuning 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 <valid signal>
Output terminal
MRS, RES, STF, STR
RUN, FM, A, B, C
Note that the progress status of offline auto tuning is output in eight steps 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 sequence 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 executed properly.

Perform an inverter reset and restart tuning.
6) When using the motor corresponding to the following specifications and conditions, reset Pr.9 Electronic thermal O/L
relay as below after tuning is completed.
a) When the rated power specifications of the motor is 200/220V(400/440V) 60Hz, set 1.1 times rated motor current
value in Pr.9.
b) When performing motor protection from overheat using a PTC thermistor or motor with temperature detector such
as Klixon, set "0" (motor overheat protection by the inverter is invalid) in Pr.9.
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 a fault retry has been set, retry is
ignored.

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
No proportional control
For deviation step input, time (Ti) required
for only 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.
No integral control.
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%.
No function
Lower limit value.
If the measured value falls below the
setting range, the FDN signal is output.

For deviation lamp input, time (Td) required
for providing only the manipulated variable
for the proportional (P) action. As the
differential time increases, greater
response is made to a deviation change.
No differential control.
This parameter is the acceleration time of
the main speed during dancer control.
It will not function as second acceleration

4 TROUBLESHOOTING
When a fault occurs in the inverter, the inverter trips and the PU display automatically changes to one of the following fault or
alarm indications.
If the fault does not correspond to any of the following faults 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 a fault or alarm occurs, the operation panel display automatically switches to the fault
or alarm indication.
Resetting method.....................When a fault occurs, the inverter output is kept stopped. Unless reset, therefore, the inverter
cannot restart. (Refer to page 101)
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 categorized 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 trip.
(2) Warnings
The inverter does not trip even when a warning is displayed. However, failure to take appropriate measures will lead to a
fault.
(3) Alarm
The inverter does not trip. You can also output an alarm signal by making parameter setting.
(4) Fault
When a fault occurs, the inverter trips and a fault signal is output.
4.1
Reset method of protective function
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.
Inverter recovers about 1s after the reset is released.
Operation 1: ...... Using the operation panel, press
to reset the inverter.
(This may only be performed when a fault occurs (Refer to page 106 for
fault.))

If the output frequency has fallen to 1Hz by stall prevention operation and remains for 3s, a fault (E.OLT) appears and
trips the inverter. OL appears while stall prevention is being activated.
E.OLT may not occur if stall prevention (OL) is activated during output phase loss.
Check the motor for use under overload. (

Life check of the main circuit capacitor needs to be done by Pr. 259. (Refer to page 126)
125
Inspection items
(2)
Measuring method of life of the main circuit capacitor
If the value of capacitor capacity measured before shipment is considered as 100%, Pr. 255 bit1 is turned ON when the
measured value falls below 85%.
Measure the capacitor capacity according to the following procedure and check the deterioration level of the capacitor
capacity.
1) Check that the motor is connected and at a stop.
2) Set "1" (measuring start) in Pr. 259.
3) Switch power OFF. The inverter applies DC voltage to the motor to measure the capacitor capacity while the inverter
is off.
4) After confirming that the LED of the operation panel is OFF, power ON again.
5) Check that "3" (measuring completion) is set in Pr. 259 then read Pr. 258 and check the life of the main circuit
capacitor.
REMARKS
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, or FR-CV 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)
Turning the power ON during measuring before LED of the operation panel turns OFF, it may remain in "measuring" (Pr. 259 =
"2") status. In such case, carry out operation from step 2.
POINT
For accurate life measurement of the main circuit capacitor, wait 3 hours or longer after turning OFF. The
temperature left in the main circuit capacitor affects measurement.
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.
126
Inspection items
5.1.5
Cleaning
Always run the inverter in a clean status.
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.
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.
5.1.6
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.

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 surrounding air 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.
POINT
Refer to page 126 to perform the life check of the main circuit capacitor.
(3)
Relays
To prevent a contact fault, etc., relays must be replaced according to the cumulative number of switching times (switching life).

The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated duty, allow time for
the inverter and motor to return to or below the temperatures under 100% load.
∗4 The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range. However,
the pulse voltage value of the inverter output side voltage remains unchanged at about 2 that of the power supply.
∗5 The braking torque indicated is a short-duration average torque (which varies with motor loss) when the motor alone is decelerated from 60Hz 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 (FR-BU2) may also be used. (Option brake resisitor cannot be used for 0.1K and 0.2K.)
∗6 The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and cables).
∗7 Setting 2kHz or more in Pr. 72 PWM frequency selection to perform low acoustic noise operation in the surrounding air temperature exceeding 40°C (totallyenclosed structure is 30°C), the rated output current is the value in parenthesis.
∗8
Connect DC power supply to terminal P/+ and N/-. Connect the plus side of the power supply to terminal P/+ and minus side to terminal N/-.
Since the voltage between P/+ and N/- may increase due to the regeneration energy from the motor and exceeds 415V temporarily, select the DC power
supply which can withstand the voltage/energy during regeneration. If using the power supply which can not withstand voltage/energy during regeneration,
insert diodes in series for reverse current prevention.
Although the FR-E700 series has the built-in inrush current limit circuit, select the DC power supply considering the inrush current at powering ON as the
inrush current four times of the rated inverter flows at powering ON.
Since the power supply capacity depends on the output impedance of the power, select the power supply capacity which has enough allowance according
to the AC power supply system capacity.
∗9 The safety stop function model is indicated with SC.
∗10 Totally enclosed structure series ends with -C.

The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor.
The rated output capacity indicated assumes that the output voltage is 230V.
The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated duty, allow time for
the inverter and motor to return to or below the temperatures under 100% load. If the automatic restart after instantaneous power failure function (Pr. 57) or
power failure stop function (Pr. 261) is set and power supply voltage is low while load becomes bigger, the bus voltage decreases to power failure detection
level and load of 100% or more may not be available.
∗4 The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range. However,
the pulse voltage value of the inverter output side voltage remains unchanged at about 2 that of the power supply.
∗5 The braking torque indicated is a short-duration average torque (which varies with motor loss) when the motor alone is decelerated from 60Hz 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

∗7 Setting 2kHz or more in Pr. 72 PWM frequency selection to perform low acoustic noise operation with the surrounding air temperature exceeding 40°C, the
rated output current is the value in parenthesis.
∗8 For single-phase 100V power input model, the maximum output voltage is twice the amount of the power supply voltage and cannot be exceeded.
∗9 In a single-phase 100V power input model, the output voltage may fall down when the load is heavy, and larger output current may flow compared to a
threephase input model. Use the motor with less load so that the output current is within the rated motor current range.
∗10 The safety stop function model is indicated with SC.
