In this Installation Guideline, the safety instruction levels are classified into "WARNING" and "CAUTION".
WARNING
Assumes that incorrect handling may cause hazardous conditions, resulting in death or severe injury.
CAUTION
Assumes that incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may
cause physical damage only.
CAUTION level may lead to a serious consequence according to conditions. Please follow strictly the instructions
Note that even the
of both levels because they are important to personnel safety.
Electric Shock Prevention
WARNING
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 removed. Otherwise, you may access the exposed high-voltage 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, 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. Earthing must conform to the requirements of national and local safety regulations and electrical codes
(JIS, NEC section 250, IEC 536 class 1 and other applicable standards). A neutral-point earthed power supply for 400V class inverter in
compliance with EN standard must be used.
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.
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 47.)
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 replace the cooling fan while power is on. It is dangerous to replace the cooling fan while power is on.
Do not touch the printed circuit board or handle the cables with wet hands. 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.
A PM motor is a synchronous motor with high-performance magnets embedded in the rotor. Motor terminals holds high-voltage while the
motor is running even after the inverter power is turned OFF. Before wiring or inspection, the motor must be confirmed to be stopped. In
an application, such as fan and blower, where the motor is driven by the load, a low-voltage manual motor starter must be connected at
the inverter's output side, and wiring and inspection must be performed while the motor starter is open. Otherwise you may get an electric
shock.
Fire Prevention
CAUTION
Mount the inverter to incombustible material. 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 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, 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.
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.
Be sure to perform daily and periodic inspections as specified in the Instruction Manual. If a product is used without any inspection, a
burst, breakage, or a fire may occur.
Injury Prevention
CAUTION
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 it is hot and you may get burnt.
Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric shock, etc.
Transportation and installation
CAUTION
Any person who is opening a package using a sharp object, such as a knife and cutter, must wear gloves to prevent injuries caused
by the edge of the sharp object.
When carrying products, use correct lifting gear to prevent injury.
Do not stand or rest heavy objects on the product.
Do not stack the inverter boxes higher than the number recommended.
When carrying the inverter, do not hold it by the front cover or setting dial; it may fall off or fail.
During installation, caution must be taken not to drop the inverter as doing so may cause injuries.
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 the product on a hot surface.
Check the inverter mounting orientation is correct.
The inverter must be installed on a strong surface securely with screws so that it will not drop.
Do not install or operate the inverter if it is damaged or has parts missing. This can result in breakdowns.
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.
Use the inverter under the following environmental conditions. Otherwise, the inverter may be damaged.

If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.) infiltrate into a Mitsubishi product, the product will be damaged.
Halogen-based materials are often included in fumigant, which is used to sterilize or disinfect wooden packages. When packaging,
prevent residual fumigant components from being infiltrated into Mitsubishi products, or use an alternative sterilization or disinfection
method (heat disinfection, etc.) for packaging. Sterilization of disinfection of wooden package should also be performed before
packaging the product.
To prevent a failure, do not use the inverter with a part or material containing halogen flame retardant including bromine.
Wiring
CAUTION
Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not approved
from Mitsubishi. These devices on the inverter output side may be overheated or burn out.
The direction of rotation of the motor corresponds to the direction of rotation commands (STF/STR) only if the phase sequence (U, V,
W) is maintained.
PM motor terminals (U, V, W) hold high-voltage while the PM motor is running even after the power is turned OFF. Before wiring, the
PM motor must be confirmed to be stopped. Otherwise you may get an electric shock.
Never connect an PM motor to the commercial power supply.
Applying the commercial power supply to input terminals (U,V, W) of an PM motor will burn the PM motor. The PM motor must be
connected with the output terminals (U, V, W) of the inverter.
Test operation and adjustment
CAUTION
Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected
motions.
Operation
WARNING
When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.
Since pressing the
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).
Make sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart the motor suddenly.
Do not use a PM motor for an application where the PM motor is driven by its load and runs at a speed higher than the maximum
motor speed.
Performing pre-excitation (LX signal and X13 signal) under torque control (Real sensorless vector control) may start the motor
running at a low speed even when the start command (STF or STR) is not input The motor may run also at a low speed when the
speed limit value = 0 with a start command input. It must be confirmed that the motor running will not cause any safety problem before
performing pre-excitation.
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.
Use this inverter only with three-phase induction motors or with a PM motor. Connection of any other electrical equipment to the
inverter output may damage the inverter as well as 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 inverter.
CAUTION
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.
Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. Otherwise, the life of the inverter
decreases.
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.
Take appropriate measures regarding harmonics. Otherwise this can endanger compensation systems or overload generators.
When driving a 400V class motor by the inverter, the motor must be an insulation-enhanced motor or measures must be taken to
suppress surge voltage. Surge voltage attributable to the wiring constants may occur at the motor terminals, deteriorating the
insulation of the motor.
Use a motor designed for inverter operation. (The stress for motor windings is bigger than in line power supply).
When parameter clear or all clear is performed, set again 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.
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.
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.
Only one PM motor can be connected to an inverter.
A PM motor must be used under PM sensorless vector control. Do not use a synchronous motor, induction motor, or synchronous
induction motor.
Do not connect a PM motor in the induction motor control settings (initial settings). Do not use an induction motor in the PM
sensorless vector control settings. It will cause a failure.
In the system with a PM motor, the inverter power must be turned ON before closing the contacts of the contactor at the output side.
Emergency stop
CAUTION
Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the
inverter fails.
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.
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.
Maintenance, inspection and parts replacement
CAUTION
Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It will cause a failure.
Disposing of the inverter
Treat as industrial waste.
CAUTION
General instructions
Many of the diagrams and drawings in instruction manuals show the inverter without a cover, or partially open. Never run the inverter in
this status. Always replace the cover and follow instruction manuals when operating the inverter. For more details on the PM motor,
refer to the Instruction Manual of the PM motor.

For the FR-A820-03800(75K) or higher and FR-A840-02160(75K) or higher, or if using a motor with a capacity of 75 kW or higher,
always connect a DC reactor (FR-HEL), which is available as an option.
(When selecting a DC reactor, refer to page 44, and select one suitable for the applicable motor capacity.) If a jumper is installed
across the terminals P1 and P/+, remove the jumper before installing the DC reactor.
*2 When using separate power supply for the control circuit, remove the jumper between R1/L11 and S1/L21.
*3
No input voltage is allowed for these terminals. The function of these terminals can be changed with the input terminal assignment
(Pr. 178 to Pr. 189). (Refer to page 24.)
*4
Terminal JOG is also used as the pulse train input terminal. Use Pr. 291 to choose JOG or pulse.
*5
Terminal input specifications can be changed by analog input specification switchover (Pr. 73, Pr. 267). To input a voltage (0 to 5 V/0 to
10 V), set the voltage/current input switch OFF. To input a current (4 to 20 mA), set the voltage/current input switch ON. Terminals 10
and 2 are also used as a PTC input terminal. (Pr. 561) (Refer to the Instruction Manual.)
*6
It is recommended to use 2W, 1kΩ when the frequency setting signal is changed frequently.
*7

WIRING
CAUTION
The power supply cables must be connected to R/L1, S/L2, T/L3. Never connect the power cable to the U, V, W, of the
inverter. Doing so will damage the inverter. (Phase sequence needs not to be matched.)
Connect the motor to U, V, W. At this time turning on the forward rotation switch (signal) rotates the motor in the
counterclockwise direction when viewed from the motor shaft. (The phase sequence must be matched.)
The charge lamp will turn ON when the power is supplied to the main circuit.
When wiring the inverter main circuit conductor of the FR-A840-05470(220K) or higher, tighten a nut from the right side
of the conductor. When wiring two wires, place wires on both sides of the conductor (refer to the drawing). For wiring,
use bolts (nuts) provided with the inverter.

WIRING
3.3 Wiring fundamentals
3.3.1 Cable size
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.

or lower and the sine wave filter (MTBSL, MT-BSC) to the output side of the FR-A840-02160(75K) or higher.
With PM motor
Use the wiring length of 100 m or shorter when connecting a PM motor.
Use one PM motor for one inverter. Multiple PM motors cannot be connected to an inverter.
When the wiring length exceeds 50 m for a 400V class motor driven by an inverter under PM sensorless vector control,
set "9" (6 kHz) or less in Pr. 72 "PWM frequency selection".
CAUTION
Especially for long-distance wiring, the inverter may be affected by a charging current caused by stray capacitances of
the wiring, leading to an activation of the overcurrent protection, malfunction of the fast-response current limit operation,
or even to an inverter failure. If the fast-response current limit function malfunctions, disable this function.
(For Pr. 156 "Stall prevention operation selection", refer to the Instruction Manual.)
The optional surge voltage suppression filter (FR-ASF-H/FR-BMF-H) or sine wave filter (MT-BSL/MT-BSC) cannot be
used under PM sensorless vector control. Do not connect it.
For details of Pr. 72 "PWM frequency selection", refer to the Instruction Manual.
The FR-ASF-H and FR-BMF-H can be used under V/F control and Advanced magnetic flux vector control. The MT-BSL
and MT-BSC can be used under V/F control.

For the control circuit wiring, strip off the sheath of a cable, and use it with a blade terminal. For a single wire, strip off the
sheath of the wire and apply directly. Insert the blade terminal or the single wire into a socket of the terminal.
(1) Strip off the sheath for the below length. If the length of the sheath peeled is too long, a short circuit may occur with
neighbouring wires. If the length is too short, wires might come off.
Wire the stripped cable after twisting it to prevent it from becoming loose. In addition, do not solder it.

3.4.3 Wiring precautions
It is recommended to use the cables of 0.75mm² gauge for connection to the control circuit terminals.
The wiring length should be 30m (200 m for the terminal FM) maximum.
Use two or more parallel micro-signal contacts or twin
contacts to prevent a contact faults when using contact
inputs since the control circuit input signals are microcurrents.
To suppress EMI, use shielded or twisted cables for the
control circuit terminals and run them away from the main
and power circuits (including the 200 V relay sequence

circuit). For the cables connected to the control circuit
terminals, connect their shields to the common terminal
of the connected control circuit terminal. When connecting an external power supply to the terminal PC, however,
connect the shield of the power supply cable to the negative side of the external power supply. Do not directly earth the
shield to the enclosure, etc.
Do not apply a voltage to the contact input terminals (e.g. STF) of the control circuit.
Always apply a voltage to the alarm output terminals (A1, B1, C1, A2, B2, C2) via a relay coil, lamp, etc.

4 FAILSAFE OF THE SYSTEM WHICH USES THE
INVERTER
When a fault is detected by the protective function, the protective function activates and output a fault signal (ALM). 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.
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, 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.
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 current is
flowing through the motor while the motor coasts to stop, even after the inverter's start signal is turned 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.
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.

5 PRECAUTIONS FOR USE OF THE INVERTER
The FR-A800 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:
Use crimping terminals with insulation sleeve to wire the power supply and motor.
Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring.
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.
Use cables of the appropriate size to make a voltage drop of 2% maximum.
If the wiring distance is long between the inverter and motor, a voltage drop in the main circuit will cause the motor
torque to decrease especially at the output of a low frequency.
Refer to page 10 for the recommended cable size.
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 13)
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, activate the EMC filter (turn ON the
EMC filter ON/OFF connector) to minimize interference. (Refer to the Instruction Manual.)
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.
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.
If "EV" is displayed on the operation panel, turn OFF the 24 V external power supply before performing wiring.
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.
Do not use the inverter input side magnetic contactor (MC) 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.
Across terminals P/+ and PR, connect only an external brake resistor.
Do not connect a mechanical brake.
Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.
Contact 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 10E and 5.
Provide electrical and mechanical interlocks for MC1 and
MC1 Interlock
MC2 which are used for commercial power supply-inverter
switch-over.

the power supply due to arcs generated at the time of
Inverter
switch-over or chattering caused by a sequence error.
(The commercial power supply operation is not available with vector control dedicated motors (SF-V5RU, SFTHY) nor
with PM motors.)
If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor (MC) 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.
20
PRECAUTIONS FOR USE OF THE INVERTER
Vector control is available with an encoder-equipped motor. And such an encoder must be directly connected to a motor
shaft without any backlash. (Real sensorless vector control does not require an encoder.)
Inverter input side magnetic contactor (MC)
On the inverter input side, connect an 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 JEM1038AC-3 class rated current.
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.
An PM motor is a synchronous motor with high-performance magnets embedded inside. High-voltage is generated at
the motor terminals while the motor is running even after the inverter power is turned OFF. Before wiring or inspection,
confirm that the motor is stopped. In an application, such as fan and blower, where the motor is driven by the load, a
low-voltage manual contactor must be connected at the inverter's output side, and wiring and inspection must be
performed while the contactor is open. Otherwise you may get an electric shock.
Countermeasures against inverter-generated EMI
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).
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. Adding a margin to the current can eliminate such a condition. For a general-purpose motor,
use an inverter of a higher capacity (up to 2 ranks). For a PM motor, use an inverter and a PM motor of higher capacities
(up to 2 ranks).
Make sure that the specifications and rating match the system requirements.

7 TROUBLESHOOTING
When a fault occurs in the inverter, the protective function activates, and the PU display automatically changes to one of
the fault or alarm indications listed on page 43.
If the fault does not correspond to any of the following errors or if you have any other problem, please contact your sales
representative.
Retention of alarm output signal........When the magnetic contactor (MC) provided on the 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.
Alarm display.....................................When the protective function is activated, the operation panel display
automatically switches to the fault or alarm indication.
Resetting method ..............................When a protective function of the inverter is activated, the inverter output is kept
stopped. Unless reset, the inverter cannot restart. (Refer to page 42.)
When the protective functions were activated, take an appropriate corrective action, then reset the inverter, and resume
the operation. Not doing so may lead to an inverter fault and damage.
Inverter fault or alarm indications are roughly divided as below:
Error Message
A message regarding operational fault and setting fault by the operation panel (FR-DU08) and parameter unit
(FR-PU07) is displayed. The inverter does not shut off output.
Warning
The inverter does not shut off output even when a warning is displayed. However, failure to take appropriate measures
will lead to a fault.
Alarm
The inverter does not shut off output.You can also output an alarm signal by making parameter setting.
Fault
When the protective function is activated, the inverter output is shut off and a fault signal is output.
NOTES
For the details of fault displays and other malfunctions, also refer to the Instruction Manual.
Past eight faults can be displayed using the setting dial. (Refer to page 23.)

TROUBLESHOOTING
7.1 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 reset is cancelled.
Three different methods can be used to reset an inverter.
Using the operation panel, press the STOP/RESET key to reset the inverter.
(This may only be performed when a fault occurs.)
Switch OFF the power once, then switch it ON again after the indicator of the operation
panel turns OFF.
ON
OFF
Turn ON the reset signal (RES) for more than 0.1 s. (If the RES signal is kept ON,
"Err." appears (flickers) to indicate that the inverter is in a reset status.)
Inverter
RES
SD
CAUTION
OFF status of the start signal must be confirmed before resetting the inverter fault. Resetting inverter fault with the start
signal ON restarts the motor suddenly. This may cause injury.

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 220V.
When an operation is performed with the carrier frequency set to 3kHz or more, and the inverter output current reaches the value indicated in the
parenthesis of the rated current, the carrier frequency is automatically lowered. The motor noise becomes louder accordingly.
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.
The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range. However,
the maximum point of the voltage waveform at the inverter output side is the power supply voltage multiplied by about √2.
Value by the built-in brake resistor
Value for the ND rating
The rated input current indicates a value at a rated output voltage. The impedance at the power supply side (including those of the input reactor and
cables) affects the rated input current.
The power supply capacity is the value when at the rated output current. It varies by the impedance at the power supply side (including those of the input
reactor and cables).

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 440V.
When an operation is performed with the carrier frequency set to 3kHz or more, and the inverter output current reaches the value indicated in the
parentheses of the rated current, the carrier frequency is automatically lowered. The motor noise becomes louder accordingly.
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.
The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range. However,
the maximum point of the voltage waveform at the inverter output side is the power supply voltage multiplied by about √2.
Value by the built-in brake resistor
Value for the ND rating
The rated input current indicates a value at a rated output voltage. The impedance at the power supply side (including those of the input reactor and
cables) affects the rated input current.
The power supply capacity is the value when at the rated output current. It varies by the impedance at the power supply side (including those of the input
reactor and cables).
FR-DU08: IP40 (except for the PU connector section)
For the power voltage exceeding 480V, set Pr. 977 "Input voltage mode selection". (For details, refer to the Instruction Manual.)
The braking capability of the inverter built-in brake can be improved with a commercial brake resistor. For the details, please contact your sales
representative.

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 set
one of "1", "13" to "16", "50", "53", "54" 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.
*2 The % value denotes the percentage to the inverter rated

The internal accumulated heat value of the electronic thermal relay function is reset by inverter power reset and reset
signal input. Avoid unnecessary reset and power-OFF.
When using multiple motors with one inverter, or using a multi-pole motor or a specialized motor, provide an external
thermal relay (OCR) between the inverter and motor. And for the setting of the thermal relay, add the line-to line leakage
current to the current value on the motor rating plate (details in the Instruction Manual). For low-speed operation where
the cooling capability of the motor reduces, it is recommended to use a thermal protector or thermistor-incorporated
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.
Set Pr. 9 = "0" for vector-control-dedicated motors (SF-V5RU) because they are equipped with thermal protectors.
Electronic thermal relay may not operate when 5% or less of rated inverter current is set to electronic thermal relay
setting.
Motor over temperature sensing is not provided by the drive.
