circuits and get an electric shock.
앫 Before starting wiring or inspection, 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.
앫 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 a neutral-point earthed (grounded) power supply for 400 V class inverter in compliance with EN standard.
앫 Any person who is involved in the wiring or inspection of this equipment should be fully competent to do the work.
앫 Always install the inverter before wiring. Otherwise you may get an electric shock or be injured.
앫 If your application requires by installation standards an RCD (residual current device) as up stream protection please select
according to DIN VDE 0100-530 as following:
Single phase inverter type A or B
Three phase inverter only type B
(Additional instructions on the use of a residual current device are contained on page 27.)
앫 Perform setting dial and key operations with dry hands to prevent an electric shock. Otherwise you may get an electric shock.
앫 Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an electric shock.
앫 Do not replace the cooling fan while power is on. It is dangerous to replace the cooling fan while power is on.
앫 Do not touch the printed circuit board or handle the cables with wet hands. You may get an electric shock.
앫 When measuring the main circuit capacitor capacity, the DC voltage is applied to the motor for 1 s at powering off. Never touch
the motor terminal, etc. right after powering off to prevent an electric shock.
3.2 Fire Prevention
CAUTION
앫 Install the inverter on a nonflammable wall without holes (so that nobody can touch the inverter heatsink on the rear side, etc.).
Mounting it to or near flammable material can cause a fire.
앫 If the inverter has become faulty, switch off the inverter power. A continuous flow of large current could cause a fire.
앫 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.
앫 Do not connect a resistor directly to the DC terminals P/+, N/–. This could cause a fire and destroy the inverter. The surface
temperature of braking resistors can far exceed 100 °C for brief periods. Make sure that there is adequate protection against
accidental contact and a safe distance is maintained to other units and system parts.
3.3 Injury Prevention
CAUTION
앫 Apply only the voltage specified in the instruction manual to each terminal. Otherwise, burst, damage, etc. may occur.
앫 Ensure that the cables are connected to the correct terminals. Otherwise, burst, damage, etc. may occur.
앫 Always make sure that polarity is correct to prevent damage, etc. Otherwise, burst, damage, etc. may occur.
앫 While power is on or for some time after power-off, do not touch the inverter as it is hot and you may get burnt.

(U, V, W) is maintained.
4.3 Test Operation and Adjustment
CAUTION
앫 Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected motions.
4.4 Operation
DANGER
앫 When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.
앫 Since pressing
key may not stop output depending on the function setting status, provide a circuit and switch separately
to make an emergency stop (power off, mechanical brake operation for emergency stop, etc).
앫 Make sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart the motor suddenly.
앫 The inverter can be started and stopped via the serial port communications link or the field bus. However, please note that
depending on the settings of the communications parameters it may not be possible to stop the system via these connections
if there is an error in the communications system or the data line. In configurations like this it is thus essential to install
additional safety hardware that makes it possible to stop the system in an emergency (e.g. controller inhibit via control signal,
external motor contactor etc). Clear and unambiguous warnings about this must be posted on site for the operating and
service staff.
앫 The load used should be a three-phase induction motor only. Connection of any other electrical equipment to the inverter
output may damage the inverter as well as the equipment.
앫 Do not modify the equipment.
앫 Do not perform parts removal which is not instructed in this manual. Doing so may lead to fault or damage of the inverter.
CAUTION
앫 The electronic thermal relay function does not guarantee protection of the motor from overheating. It is recommended to install
both an external thermal and PTC thermistor for overheat protection.
앫 Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. Otherwise, the life of the
inverter decreases.
앫 Use a noise filter to reduce the effect of electromagnetic interference and follow the accepted EMC procedures for proper
installation of frequency inverters. Otherwise nearby electronic equipment may be affected.
앫 Take appropriate measures regarding harmonics. Otherwise this can endanger compensation systems or overload generators.
앫 When a 400 V class motor is inverter-driven, please use an insulation-enhanced motor or measures taken to suppress surge
voltages. Surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of
the motor.
앫 When parameter clear or all clear is performed, set again the required parameters before starting operations. Each parameter
returns to the initial value.
앫 The inverter can be easily set for high-speed operation. Before changing its setting, fully examine the performances of the motor
and machine.
앫 The DC braking function of the frequency inverter is not designed to continuously hold a load. Use an electro-mechanical holding
brake on the motor for this purpose.
앫 Before running an inverter which had been stored for a long period, always perform inspection and test operation.
앫 For prevention of damage due to static electricity, touch nearby metal before touching this product to eliminate static electricity
from your body.
앫 If you are installing the inverter to drive a three-phase device while you are contracted for lighting and power service, consult
your electric power supplier.
4.5 Emergency Stop
CAUTION
앫 Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions
if the inverter fails.
앫 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.
앫 When the protective function is activated (i. e. the frequency inverter switches off with an error message), take the corresponding
corrective action as described in the inverter manual, then reset the inverter, and resume operation.
4.6 Maintenance, Inspection and Parts Replacement
CAUTION
앫 Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It will cause a failure.
It is recommended to make the following checks periodically:
앫 Check for loose screws in the terminal block. Retighten any loose screws.
앫 Check for dust accumulation on the inverter. Clean the heat sink and the cooling fan of the inverter.
앫 Check for unusual noise generated by the inverter. Retighten installation screw.
앫 Check for the operation condition. Keep the operation condition of inverter as written in the manual.
4.7 Disposal of the Inverter

Note that the motor windings in three-phase AC motors are subject to far more stress when operated via frequency inverters than
with mains operation. The motor must have been approved by the manufacturer for operation on a frequency inverter.
In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a 400 V
class motor, the surge voltage may deteriorate the insulation. When the 400 V class motor is driven by the inverter, consider the
following measures:
앫 Use a "400 V class inverter-driven insulation-enhanced motor" and set frequency in Pr. 72 PWM frequency selection according to
wiring length.
Wiring Length

Carrier frequency
14.5 kHz

앫 Limiting the voltage rise speed of the frequency inverter output voltage (dV/dT):
If the motor requires a rise speed of 500 V/μs or less you must install a filter in the output of the inverter. Please contact your
Mitsubishi Electric dealer for more details.
CAUTION
앫 Especially for long-distance wiring (particularly when employing shielded motor cables), 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 or fast
response current limit function, or stall prevention function or a malfunction or fault of the equipment connected on the
inverter output side.
When the fast-response current limit function malfunctions, make the function invalid. When stall prevention function misoperates,
increase the stall level. (For Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention operation selection, refer to the
Instruction Manual.)
앫 For details of Pr. 72 PWM frequency selection, refer to the Instruction Manual.
앫 When using the automatic restart after instantaneous power failure function with wiring length exceeding below, select
without frequency search (Pr. 162 = "1", "11"). (Refer to the instruction manual for further information to Pr. 162).

PRECAUTIONS FOR USE OF THE INVERTER
The FR-D700 SC 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.
앫 Use crimping terminals with insulation sleeve to wire the power supply and motor.
앫 Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring.
앫 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 a control
box etc., take care not to allow chips and other foreign matter to enter the inverter.
앫 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 7 for the recommended cable size.
앫 The overall wiring length should be within the prescribed length.
Especially for long distance wiring, the fast-response current limit function may be reduced or the equipment connected to the
inverter output 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 8)
앫 Electromagnetic Compatibility
Operation of the frequency inverter can cause electromagnetic interference in the input and output that can be propagated by
cable (via the power input lines), by wireless radiation to nearby equipment (e.g. AM radios) or via data and signal lines. Install
an optional filter if present to reduce air propagated interference on the input side of the inverter. Use AC or DC reactors to
reduce line propagated noise (harmonics). Use shielded motor power lines to reduce output noise.
For EMC correct installation refer to the Manual for Frequency Inverters and EMC.
앫 Do not install a power factor correction capacitor, varistor or arrester on the inverter output side. This will cause the inverter to
trip or the capacitor, varistor, or arrester to be damaged. If any of the above devices is installed, immediately remove it.
앫 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.
앫 A short circuit or earth 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 fault caused by wiring inadequacy or reduced motor insulation resistance may damage the
inverter modules.
– Fully check the to-earth insulation and inter-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.
앫 Do not use the inverter input side magnetic contactor to start/stop the inverter.
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.
Always use the start signal (ON/OFF of STF and STR signals) to start/stop the inverter.
앫 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 FR-D720S-008SC and 014SC. Leave terminals P/+ and PR open.
Also, never short between P/+ and PR.
13
PRECAUTIONS FOR USE OF THE INVERTER
앫 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.
앫 Provide electrical and mechanical interlocks for MC1 and MC2 which are
Interlock
used for bypass operation.
When the wiring is incorrect or if there is a bypass circuit as shown on
M
Power
3~
supply
the right, the inverter will be damaged by leakage current from the
power supply due to arcs generated at the time of switch-over or chattering
Undesirable Current
caused by a sequence error.
Inverter
앫 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.
앫 Inverter input side magnetic contactor (MC)
On the inverter input side, connect a MC for the following purposes. (Refer to the Instruction Manual.)
– To release the inverter from the power supply when a 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.
– To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power failure
– To separate the inverter from the power supply to ensure safe maintenance and inspection work. If using an MC for emergency
stop during operation, select an MC regarding the inverter input side current as JEM1038-AC-3 class rated current.
앫 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 MC is provided for switching to the commercial power supply, for example, switch it ON/OFF after the inverter and motor
have stopped.
앫 Instructions for overload operation
When performing operation of frequent start/stop of the inverter, increase/decrease in the temperature of the transistor
element of the inverter may repeat due to a continuous 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 bound current, starting current, etc.
Decreasing current may increase the life. However, decreasing current will result in insufficient torque and the inverter may not
start. Therefore, increase the inverter capacity to have enough allowance for current.
앫 Make sure that the specifications and rating match the system requirements.
앫 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 when applying the motor speed by the analog signal.
– Do not run the signal cables and power cables (inverter I/O cables) in parallel with each other and do not bundle them.
– Run signal cables as far away as possible from power cables (inverter I/O cables).
– Use shielded cables as signal cables.
– Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).

FAILSAFE OF THE SYSTEM WHICH USES THE INVERTER
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 Electric 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.
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.
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.

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, 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. 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.

TROUBLESHOOTING
The frequency inverter FR-D700 SC has a multitude of protective functions which protect the drive and the inverter from damage
in case of a fault. When a fault occurs in the inverter, the protective function is activated bringing the inverter to an alarm stop and
the PU display automatically changes to any of the following fault (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.
앫 Retention of fault output signal..... When the magnetic contactor (MC) provided on the input side of the inverter is opened at
the activation of the protective function, the inverter's control power will be lost and the alarm
output will not be held.
앫 Fault or alarm display......................... When a fault or alarm occurs, the operation panel display automatically switches to the fault
or alarm indication.
앫 Resetting method ............................... When a protective function of the inverter is activated, the power output of the inverter is
blocked (motor is coasting). The inverter cannot start up again unless an automatic restart
has been configured or the inverter is reset. Please observe carefully the warnings contained
below in the configuration of an automatic restart or the execution of a reset.
앫 If protective functions were activated (i. e. the inverter switched off with an error message) follow the instructions for error correction
provided in the manual for the inverter. Especially in the case of short circuits or earth contacts in the inverter output and mains
overvoltages the cause of the fault must be determined prior to switching on again as a recurrence of such faults at short intervals can
lead to premature aging of components or even the complete breakdown of the device. After the cause of the fault has been found
and corrected the inverter can be reset and operations continue.
Inverter fault or alarm indications are roughly divided as below.
앫 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.
앫 Warning
The inverter does not shut off output even when a warning is displayed. However, failure to take appropriate measures will lead

The applied motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi Electric 4-pole standard motor.
*2
The rated output capacity indicated assumes that the output voltage is 230 V/440 V (200 V class/400 V class).
*3
The % value of the overload current rating indicated is the ratio of the overload current to the inverter’s rated output current (ambient temperature of 50 °C for 400 V
class). 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 60 Hz 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.
*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
When operating the inverter with ambient temperature of 40 °C maximum, the rated output current is the value in parentheses.

This function detects the overload (overheat) of the motor,
stops the operation of the inverter's output transistor, and
stops the output.
When using the Mitsubishi Electric constant-torque motor
set "1" or any of "13", "50" or "53" in Pr. 71. This provides
a 100 % continuous torque characteristic in the low-speed
range. Set the rated current of the motor in Pr. 9.
When 50 % of the inverter rated output current (current value)
is set in Pr. 9.
The % value denotes the percentage to the inverter rated output
current. It is not the percentage to the motor rated current.
When you set the electronic thermal relay function dedicated
to the Mitsubishi Electric constant-torque motor, this characteristic
curve applies to operation at 6 Hz or higher.
APPENDIX
CAUTION
앫 Protective function by electronic thermal relay function is reset by inverter power reset and reset signal input. Avoid unnecessary
reset and power-OFF.
앫 Install an external thermal relay (OCR) between the inverter and a motor when operating several motors by one inverter, or
when using a multi-pole motor or special motor. In this case, set 0A to the electronic thermal O/L relay setting of the inverter.
For the external thermal relay, determine the setting value in consideration of the current indicated on the motor's rating plate
and the line-to-line leakage current. Self-cooling ability of a motor is reduced at low speed operation. Use a motor with a builtin thermal protector.
앫 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.
앫 A special motor cannot be protected by the electronic thermal relay function. Use an external thermal relay.
