(8) Application of caution labels
Do not install a power factor correction capacitor, surge
absorber, or radio noise filter on the output side of this
product. These devices may overheat or burn out.
The connection orientation of the output cables U, V, W to
the motor affects the rotation direction of the motor.
Before starting operation, each parameter must be
confirmed and adjusted. Failure to do so may cause some
machines to make unexpected motions.
Stay away from the equipment when the retry function is set
as it will restart suddenly after trip.
Since pressing key may not stop output depending on
the function setting status, separate circuit and switch that
make an emergency stop (power OFF, mechanical brake
operation for emergency stop, etc.) must be provided.
OFF status of the start signal must be confirmed before
resetting the inverter fault. Resetting inverter alarm with the
start signal ON restarts the motor suddenly.
The inverter must be used for three-phase induction motors.
Connection of any other electrical equipment to the product
output may damage the equipment.
Do not modify the equipment.
Do not perform parts removal which is not instructed in this
manual. Doing so may lead to fault or damage of the product.
The electronic thermal relay function does not guarantee
protection of the motor from overheating. 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.
The effect of electromagnetic interference must be reduced
by using an EMC filter or by other means. Otherwise nearby
electronic equipment may be affected.
Appropriate precautions must be taken to suppress
harmonics. Otherwise power supply harmonics from the
inverter may heat/damage the power factor correction
capacitor and generator.
When driving a 400V class motor with the inverter, the motor
must be an insulation-enhanced motor or measures must be
taken to suppress surge voltage. Otherwise surge voltage,
which is attributed to the length and thickness of wire, may
occur at the motor terminals, causing the motor insulation
to deteriorate.
When parameter clear or all parameter clear is performed, the
required parameters must be set again before starting
operations because all parameters return to the initial value.
The inverter can be easily set for high-speed operation.
Before changing its setting, the performances of the motor
and machine must be fully examined.
This product's brake function cannot be used as a
mechanical brake. Use a separate device instead.
Perform an inspection and test operation of this product if it
has been stored for a long period of time.
Static electricity in your body must be discharged before
you touch the product. Otherwise the product may be
damaged.

2 INSTALLATION AND WIRING
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
)
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 8.)
Do not install a power factor correction capacitor, surge suppressor or noise filter (capacitor) on the inverter output
side. This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above
devices are connected, immediately remove them.
Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the communication
devices (such as AM radios) used near the inverter. In this case, install the FR-BIF optional noise filter (capacitor) (for use in the
input side only) or FR-BSF01 or FR-BLF noise filter (ferrite core) to minimize interference.
(
Refer to Chapter 3 of the
Instruction Manual (Applied)
.)
Refer to the Instruction Manual of each option and peripheral devices for details of peripheral devices.
AC power supply
Use within the permissible power supply
specifications of the inverter. To ensure
safety, use a molded case circuit breaker,
earth leakage circuit breaker or magnetic
contactor to switch power ON/OFF.
Magnetic contactor (MC)
Install the magnetic contactor to ensure
safety. Do not use this magnetic contactor
to start and stop the inverter. Doing so will
cause the inverter life to be shortened.
Noise filter (ferrite core)
(FR-BSF01, FR-BLF)
Install a noise filter (ferrite core)
to reduce the electromagnetic
noise generated from the inverter.
Effective in the range from about
1MHz to 10MHz. A wire should be
wound four turns at a maximum.
Earth (Ground)
Devices connected to the output
Do not install a power factor correction capacitor,
surge suppressor or noise filter (capacitor) on the output
side of the inverter. When installing a molded case
circuit breaker on the output side of the inverter,
contact each manufacturer for selection of the
molded case circuit breaker.
The regenerative braking capability
of the inverter can be exhibited fully.
Power supply harmonics
can be greatly suppressed.

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

The breaker must be selected carefully
since an in-rush current flows in the
inverter at power on.
Install a noise filter (ferrite core)
to reduce the electromagnetic
noise generated from the
inverter. Effective in the range
from about 1MHz to 10MHz.
When more wires are passed
through, a more effective result
can be obtained. A wire should
be wound four turns or more.
* Filterpack (FR-BFP2), which contains DC reactor and noise filter in one package, is also available.
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.

Peripheral devices
2.1 Peripheral devices
Check the inverter model of the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity.
Refer to the following list and prepare appropriate peripheral devices.
Select a MCCB according to the power supply capacity.
Install one MCCB per inverter.
For the use in the United States or Canada, refer to "Instructions for UL and cUL" in, and select an appropriate fuse
or molded case circuit breaker (MCCB).
Magnetic contactor is selected based on the AC-1 class. The electrical durability of magnetic contactor is 500,000 times. When the magnetic contactor is
used for emergency stop during motor driving, the electrical durability is 25 times.
If using an MC for emergency stop during motor driving, select an MC regarding the inverter input side current as JEM1038-AC-3 class rated current. When
using an MC on the inverter output side for commercial-power supply operation switching using a general-purpose motor, select an MC regarding the motor
rated current as JEM1038-AC-3 class rated current.

When connecting a single-phase 100V power input model to a power transformer (50kVA or more), install an AC reactor (FR-HAL) so that the performance
is more reliable. ( Refer to Chapter 3 of the Instruction Manual (Applied))
NOTE
When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to the inverter model,
and cable and reactor according to the motor output.
When the breaker on the inverter input 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.

2.2 Installation of the inverters and precautions
(1) Installation of the inverter
Enclosure surface mounting
Remove the front cover and wiring cover to mount the inverter to the surface. (Remove the covers in the directions of the
arrows.)
(2) Environment
Before installation, check that the environment meets the specifications on page 44.
NOTE
When encasing multiple inverters, install them in parallel as a cooling
measure.
Install the inverter vertically.
For heat dissipation and maintenance, allow minimum clearance shown
in the figures below from the inverter to the other devices and to the
inner surface of the enclosure.
Allow 5cm or more clearance for 5.5K or higher.
When using the inverters at the surrounding air temperature of 40C or less, the inverters can be installed without any clearance between
them (0cm clearance).
Note
Install the inverter on a strong surface securely and vertically with bolts.
Leave enough clearances and take cooling measures.
Avoid places where the inverter is subjected to direct sunlight, high temperature and high humidity.
Install the inverter on a nonflammable wall surface.
When designing or building an enclosure for the inverter, carefully consider influencing factors such as heat
generation of the contained devices and the operating environment.

NOTE
To prevent a malfunction caused by noise, separate the signal cables more than 10cm from the power cables. Also
separate the main circuit wire of the input side and the output side.
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.
The output of the single-phase power input model is three-phase 200V.

(1) Cable sizes etc., of the main control circuit terminals and earth (ground) terminals
Select the recommended cable size to ensure that a voltage drop will be 2% or less.
If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to
decrease especially at the output of a low frequency.
The following table indicates a selection example for the wiring length of 20m.
Three-phase 200V class (when input power supply is 220V)
Three-phase 400V class (when input power supply is 440V)
Single-phase 200V class (when input power supply is 220V)
Single-phase 100V class (when input power supply is 100V)
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.
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. (For the use in the United States or Canada, refer to page 49.)
The recommended cable size is that of the cable (PVC 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.)
The terminal screw size indicates the terminal size for R/L1, S/L2, T/L3, U, V, W, PR, P/+, N/-, P1 and a screw for earthing (grounding).
Screw size for earthing (grounding) the FR-D720-15K is indicated in parentheses.
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).
The line voltage drop can be calculated by the following formula:
Line voltage drop [V] =

(2) Total wiring length
The overall wiring length for connection of a single motor or multiple motors should be within the value in the table below.
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
2) Connect the surge voltage suppression filter (FR-ASF-H/FR-BMF-H) on the inverter output side.

(2) Wiring method
Wiring
Use a blade terminal and a wire with a sheath stripped off for the control circuit wiring. 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 about the length below. If the length of the sheath peeled is too long, a short circuit may occur
among neighboring wires. If the length is too short, wires might come off.
Wire the stripped wire after twisting it to prevent it from becoming loose. In addition, do not solder it.
2) Crimp the blade terminal.
Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve.
Check the condition of the blade terminal after crimping. Do not use a blade terminal of which the crimping is
inappropriate, or the face is damaged.

(3) 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 terminals SD and 5 and the terminals SE and 5.
Terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM, RL) and the pulse train output
terminal (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 (terminals 2 or 4). It should be protected from external
noise using a shielded or twisted cable.
Terminal SE is a common terminal for the open collector output terminal (RUN). The contact input circuit is isolated from the
internal control circuit by photocoupler.
(4) Wiring instructions
It is recommended to use the cables of 0.3mm
2
to 0.75mm
2
gauge for connection to the control circuit terminals.
The maximum wiring length should be 30m (200m for terminal FM).
Do not short across terminals PC and SD. Inverter may be damaged.
When using contact inputs, use two or more parallel micro-signal contacts or
twin contacts to prevent contact faults since the control circuit input signals are
micro-currents.
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
200V 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 (ground) the shield to the enclosure, etc.
Always apply a voltage to the fault output terminals (A, B, C) via a relay coil, lamp, etc.
When using an external power supply for transistor output, note the following points to prevent a malfunction caused by
undesirable current.
Do not connect any terminal SD on the inverter and the 0V terminal of the external power supply (when the sink logic is
selected).
Do not connect terminal PC on the inverter and the +24V terminal of the external power supply (when the source logic is
selected).
Do not install an external power source in parallel with the internal 24VDC power source (connected to terminals PC and
SD) to use them together.
Refer to Chapter 2 of the Instruction Manual (Applied) for the detail.

Connection of a dedicated external brake resistor (MRS type, MYS type, FR-ABR)
2.4 Connection of a dedicated external brake resistor (MRS type,
MYS type, FR-ABR)
Install a dedicated brake resistor (MRS type, MYS type, FR-ABR) outside when the motor driven by the inverter is made to run
by the load, quick deceleration is required, etc. Connect a dedicated brake resistor (MRS type, MYS type, FR-ABR) to
terminal P/+ and PR. (For the locations of terminal P/+ and PR, refer to the terminal block layout (page 11).)
Set parameters below. (
Refer to the Instruction Manual (Applied) for the parameter details.)
It is recommended to configure a sequence, which shuts off power in the input side of the inverter by the external thermal
relay as shown below, to prevent overheat and burnout of the brake resistor (MRS type, MYS type) and high duty brake
resistor (FR-ABR) in case the regenerative brake transistor is damaged. (The brake resistor cannot be connected to the
0.1K and 0.2K.)
Refer to the table below for the type number of each capacity of thermal relay and the diagram below for the connection.
(Always install a thermal relay when using a brake resistor whose capacity is 11K or higher.)

PRECAUTIONS FOR USE OF THE INVERTER
3
3 PRECAUTIONS FOR USE OF THE INVERTER
The FR-D700 series is a highly reliable product, but using incorrect peripheral circuits or incorrect operation/handling methods
may shorten the product life or damage the product.
Before starting operation, always recheck the following items.
(1) Use crimp 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 appropriate size to make a voltage drop of 2% or less.
If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque
to decrease especially at the output of a low frequency. Refer to page 12 for the recommended wire sizes.
(5) The total wiring length should be within the prescribed length.
Especially for long distance wiring, the fast-response current limit function may decrease, or the equipment connected to
the output side may malfunction. This is caused by a charging current due to the stray capacity of the wiring. Therefore,
note the overall wiring length. (Refer to page 13)
(6) Electrical corrosion of the bearing
When a motor is driven by the inverter, axial voltage is generated on the motor shaft, which may cause electrical
corrosion of the bearing in rare cases depending on the wiring, load, operating conditions of the motor or specific inverter
settings (high carrier frequency, use of a capacitive filter).
The following shows examples of countermeasures for the inverter.
Decrease the carrier frequency.
Remove the capacitive filter.
Provide a common mode choke on the output side of the inverter. (This is effective regardless of the use of the
capacitive filter.)
Mitsubishi Electric capacitive filter: FR-BIF, SF[], FR-E5NF-[], FR-S5NFSA[], FR-BFP2-[]
Recommended common mode choke: FT-3KM F series FINEMET
®
common mode choke cores manufactured by Hitachi Metals, Ltd.
FINEMET is a registered trademark of Hitachi Metals, Ltd.
(7) Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the
communication devices (such as AM radios) used near the inverter. In this case, install the FR-BIF optional capacitor
type filter (for use in the input side only) or FR-BSF01 or FR-BLF line noise filter to minimize interference.
(8) Do not install a power 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 a single-phase power input model,
make sure of secure insulation of T/L3-phase, and connect to the input side of the inverter.)
(9) 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 no more than 30VDC
using a tester.
20
PRECAUTIONS FOR USE OF THE INVERTER
(10) 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 may damage
the inverter modules. These short circuits may be caused by peripheral circuit inadequacy, an earth (ground) fault
caused by wiring inadequacy, or reduced motor insulation resistance.
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 a hostile atmosphere, securely check the motor insulation resistance etc.
(11) 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. Turn ON/OFF the inverter start controlling terminals (STF,
STR) to run/stop the inverter. ( Refer to the Instruction Manual (Applied))
(12) Across terminals P/+ and PR, connect only an external brake resistor.
Do not connect a mechanical brake.
The brake resistor cannot be connected to the
0.1K and 0.2K
. Do not connect anything to terminals P/+ and PR.
Also, never short between these terminals.
(13) 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 and 5.
(15) 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.
(16) Inverter input side magnetic contactor (MC)
On the inverter input side, connect a MC for the following purposes. (Refer to page 6 for selection.)
1) 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.
2) To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power failure
3) To separate the inverter from the power supply to ensure safe maintenance and inspection work.
Use the inverter input current as a reference for selection of an MC to perform an emergency stop during operation, and
select the MC conforming to JEM1038-AC-3 class rated operational current.
(17) 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.
(18) Countermeasures against inverter-generated EMI
If electromagnetic noise generated from the inverter causes frequency setting signal to fluctuate and motor rotation
speed to be unstable when changing motor speed with analog signal, the following countermeasures are effective.
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 shield cables as signal cables.
Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).
(14) To use the commercial power supply, be sure to provide
electrical and mechanical interlocks between the electronic
bypass contactors MC1 and MC2.
When using a switching circuit as shown right, chattering due to
misconfigured sequence or arc generated at switching may
allow undesirable current to flow in and damage the inverter.
Miswiring may also damage the inverter.

PRECAUTIONS FOR USE OF THE INVERTER
3
(19) 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).
(20) Make sure that the specifications and rating match the system requirements.
22
4 FAILSAFE OF THE SYSTEM WHICH USES THE INVERTER
When a fault occurs, the inverter output is shut off 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 and at the same time consider the system configuration where failsafe from
outside the inverter, without using the inverter, is enabled even if the inverter fails.
(1) Interlock method which uses the inverter status output signals
By combining the inverter status output signals to provide an interlock as shown below, an inverter alarm can be
detected.
(2) Backup method outside the inverter
Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure
status of the inverter itself. For example, when the inverter CPU fails, even if the interlock is provided using the inverter
fault signal, start signal and RUN signal, there is a case where a fault 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
current runs as the motor is running for the period until the motor stops since the inverter starts decelerating even if the
start signal turns OFF. For the logic check, configure a sequence considering the inverter deceleration time. In addition, it
is recommended to check the three-phase current when using the current detector.
2)Command speed and actual operation check
Check if there is no gap between the actual speed and commanded speed by comparing the inverter speed command
and detected speed of the speed detector.

ENERGY SAVING OPERATION FOR FANS AND PUMPS

6 ENERGY SAVING OPERATION FOR FANS AND
PUMPS
Set the following functions to perform energy saving operation for fans and pumps.
(1) Load pattern selection (Pr. 14)
Select the optimum output characteristic (V/F characteristic) that is suitable for the
application and load characteristics.
Set Pr.14 Load pattern selection = "1 (for variable-torque load)."
When the output frequency is equal to or less than the base frequency, the output voltage
changes by its square in proportion to the output frequency.
Use this setting to drive a load whose load torque changes in proportion to the square of
the speed, such as a fan and a pump.
(2) Optimum excitation control (Pr. 60)
Without a detailed parameter setting, the inverter automatically performs energy saving operation.
Set Pr.60 Energy saving control selection = "9 (Optimum excitation control mode)."
The Optimum excitation control mode is a control system which controls excitation current to improve the motor efficiency
to the maximum and determines output voltage as an energy saving method.
NOTE
Load pattern selection is available only under V/F control. Load pattern selection is not available under General-
purpose magnetic flux vector control. ( Refer to Chapter 4 of the Instruction Manual (Applied).)
REMARKS
When the motor capacity is too small as compared to the inverter capacity or two or more motors are connected to one inverter,
the energy saving effect is not expected.
NOTE
When the Optimum excitation control mode is selected, deceleration time may be longer than the setting value. Since
overvoltage alarm tends to occur as compared to the constant-torque load characteristics, set a longer deceleration
time.
Optimum excitation control is available only under V/F control. Optimum excitation control is not available under
General-purpose magnetic flux vector control. ( Refer to Chapter 4 of the Instruction Manual (Applied).)
Optimum excitation control will not be performed during an automatic restart after instantaneous power failure.
Since output voltage is controlled by Optimum excitation control, output current may slightly increase.

8 TROUBLESHOOTING
When a fault occurs in the inverter, the inverter output is shut off 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 at a
fault occurrence, 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 36)
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 output is not shut off.
(2) Warning
The inverter output is not shut off even when a warning is displayed. However, failure to take appropriate measures will lead to
a fault.
(3) Alarm
The inverter output is not shut off. You can also output an alarm signal by making parameter setting.
(4) Fault
When a fault occurs, the inverter output is shut off and a fault signal is output.
8.1 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.
REMARKS
For the details of fault displays and other malfunctions, also refer to the Instruction Manual (Applied).
Past eight faults can be displayed using the setting dial. (Refer to page 3 for the operation.)
Operation 1......... Using the operation panel, press to reset the inverter.
(This may only be performed when a fault occurs (Refer to page 37 for
fault.))
Operation 2......... Switch power OFF once. After the indicator of the operation panel
turns OFF, switch it ON again.
Operation 3......... Turn ON the reset signal (RES) for more than 0.1s. (If the RES signal
is kept ON, "Err." appears (blinks) to indicate that the inverter is in a
reset status.)
NOTE
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.

PRECAUTIONS FOR MAINTENANCE AND INSPECTION
The inverter is a static unit mainly consisting of semiconductor devices. Daily inspection must be performed to prevent any
fault from occurring due to the adverse effects of the operating environment, such as temperature, humidity, dust, dirt and
vibration, changes in the parts with time, service life, and other factors.
Precautions for maintenance and inspection
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.

Common specifications
Single-phase 100V power supply
The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi Electric 4-pole standard motor.
The rated output capacity assumes the following output voltages: 230V for three-phase 200V/single-phase 200V/single-phase 100V, and 440V for three-
phase 400V.
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.
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 that of the power supply.
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.
(Option brake resistor cannot be used for 0.1K and 0.2K.) A brake unit (FR-BU2) may also be used.
The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and cables).
For single-phase 100V power input model, the maximum output voltage is twice the amount of the power supply voltage and cannot be exceeded.
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 three-
phase input model. Use the motor with less load so that the output current is within the rated motor current range.
10.2 Common specifications
When using the inverters at the surrounding air temperature of 40°C or less, the inverters can be installed closely attached (0cm clearance).
Temperatures applicable for a short time, e.g. in transit.
