Even if power is off, do not remove the front cover except
for wiring or periodic inspection. You may access the
charged inverter circuits and get an electric shock.
Before starting wiring or inspection, switch off power,
check to make sure that the operation panel indicator is
off, wait for at least 10 minutes after the power supply has
been switched off, and check that there are no residual
voltage using a tester or the like. The capacitor is charged
with high voltage for some time after power off and it is
dangerous.
This inverter must be earthed (grounded). Earthing
(grounding) must conform to the requirements of national
and local safety regulations and electrical code. (NEC
section 250, IEC 536 class 1 and other applicable
standards)

off to prevent an electric shock.
when the inverter is running, do not
2. Fire Prevention
CAUTION
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.
If the inverter has become faulty, switch off the inverter
power. A continuous flow of large current could cause a
fire.
When using a brake resistor, make up a sequence that will
turn off power when an alarm signal is output. Otherwise,
the brake resistor may excessively overheat due to
damage of the brake transistor and such, causing a fire.
Do not connect a resistor directly to the DC terminals P/+
and N/-. This could cause a fire.

(2) Wiring
CAUTION
Do not install a power factor correction capacitor or surge
suppressor/capacitor type filter on the inverter output
side. These devices on the inverter output side may be
overheated or burn out.
The connection orientation of the output cables U, V, W to
the motor will affect the direction of rotation of the motor.
(3) Trial run
CAUTION
Before starting operation, confirm and adjust the
parameters. A failure to do so may cause some machines
to make unexpected motions.
(4) Usage
When you have chosen the retry function, stay away from
the equipment as it will restart suddenly after trip.
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).
Make sure that the start signal is off before resetting the
inverter alarm. A failure to do so may restart the motor
suddenly.
The load used should be a three-phase induction motor only.
Connection of any other electrical equipment to the
inverter output may damage the equipment.
Do not modify the equipment.
Do not perform parts removal which is not instructed in this
manual. Doing so may lead to fault or damage of the product.
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. Otherwise nearby electronic equipment may
be affected.
Take measures to suppress harmonics. Otherwise power
supply harmonics from the inverter may heat/damage the
power factor correction capacitor and generator.
When a 400V 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.
When parameter clear or all parameter clear is performed,
reset the required parameters before starting operations.
Each parameter returns to the initial value.
The inverter can be easily set for high-speed operation.
Before changing its setting, fully examine the
performances of the motor and machine.
In addition to the inverter’s holding function, install a
holding device to ensure safety.
Before running an inverter which had been stored for a
long period, always perform inspection and test
operation.
For prevention of damage due to static electricity, touch
nearby metal before touching this product to eliminate
static electricity from your body.

(5) 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 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.
When any protective function is activated, take the
appropriate corrective action, then reset the inverter, and
resume operation.
(6) 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.
(7) Disposal
CAUTION

The breaker must be selected carefully
since an in-rush current flows in the
inverter at power on.
(Refer to page 4)
Magnetic contactor (MC)
Install the magnetic contactor to ensure
safety. Do not use this magnetic contactor
to start and stop the inverter. Doing so will
cause the inverter life to be shorten.
(Refer to page 44)
Reactor (FR-HAL, FR-HEL option)
Reactors (option) must be used when
power harmonics measures are taken,
the power factor is to be improved or the
inverter is installed near a large power
supply system (500kVA or more). The
inverter may be damaged if you do not
use reactors. Select the reactor according
to the model. Remove the jumpers across
terminals P/+ and P1 to connect the DC reactor.

Devices connected to the output
Do not install a power factor correction capacitor,
surge suppressor or capacitor type filter on the output
side of the inverter. When installing a moulded case
circuit breaker on the output side of the inverter,
contact each manufacturer for selection of the
moulded case circuit breaker.
Earth (Ground)
To prevent an electric shock, always earth (ground)
the motor and inverter. For reduction of induction noise
from the power line of the inverter, it is recommended
to wire the earth (ground) cable by returning it to the
earth (ground) terminal of the inverter.
NOTE
The life of the inverter is influenced by surrounding air temperature. The surrounding air temperature should be as low as
possible within the permissible range. This must be noted especially when the inverter is installed in an enclosure.
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 14)
Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output
side. This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above
devices are connected, immediately remove them.
Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the
communication devices (such as AM radios) used near the inverter. In this case, install the FR-BIF optional capacitor type
filter (for use in the input side only) or FR-BSF01 or FR-BLF common mode filter to minimize interference.
Refer to the instruction manual of each option and peripheral devices for details of peripheral devices.

Inverter and peripheral devices
1.2.1Peripheral devices
Check the inverter type of the inverter you purchased. Appropriate peripheral devices must be selected according to the
capacity.
Refer to the following list and prepare appropriate peripheral devices:
∗1 Select an MCCB according to the power supply capacity.
Install one MCCB per inverter.
∗2 For installations in the United States or Canada, use the class T type fuse certified by the UL and cUL.
∗3 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.
When using the MC for emergency stop during motor driving or using on the motor side during commercial-power supply operation, select the MC with class
AC-3 rated current for the motor rated current.

Installation of the inverter and enclosure design
1.4Installation of the inverter and enclosure design
When an inverter panel is to be designed and manufactured, heat generated by contained equipment, etc., the environment of
an operating place, and others must be fully considered to determine the panel structure, size and equipment layout. The
inverter unit uses many semiconductor devices. To ensure higher reliability and long period of operation, operate the inverter
in the ambient environment that completely satisfies the equipment specifications.
1.4.1Inverter installation environment
As the inverter installation environment should satisfy the standard specifications indicated in the following table, operation in
any place that does not meet these conditions not only deteriorates the performance and life of the inverter, but also causes a
failure. Refer to the following points and take adequate measures.
Environmental standard specifications of inverter

(1) Temperature
The permissible surrounding air temperature of the inverter is between -10 and +50°C
inverter within this temperature range. Operation outside this range will considerably shorten the service lives of the
semiconductors, parts, capacitors and others. Take the following measures so that the surrounding air temperature of the
inverter falls within the specified range.
1) Measures against high temperature
Use a forced ventilation system or similar cooling system. (Refer to page 10)
Install the panel in an air-conditioned electrical chamber.
Block direct sunlight.
Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat source.
Ventilate the area around the panel well.

2
or less
(14°F to 122°F). Always operate the
2) Measures against low temperature
Provide a space heater in the enclosure.
Do not power off the inverter. (Keep the start signal of the inverter off.)
3) Sudden temperature changes
Select an installation place where temperature does not change suddenly.
Avoid installing the inverter near the air outlet of an air conditioner.
If temperature changes are caused by opening/closing of a door, install the inverter away from the door.
(2) Humidity
Normally operate the inverter within the 45 to 90% range of the ambient humidity. Too high humidity will pose problems of
reduced insulation and metal corrosion. On the other hand, too low humidity may produce a spatial electrical breakdown. The
insulation distance specified in JEM1103 "Control Equipment Insulator" is defined as humidity 45 to 85%.
1) Measures against high humidity
Make the panel enclosed, and provide it with a hygroscopic agent.
Take dry air into the enclosure from outside.
Provide a space heater in the enclosure.
2) Measures against low humidity
What is important in fitting or inspection of the unit in this status is to discharge your body (static electricity)
beforehand and keep your body from contact with the parts and patterns, besides blowing air of proper humidity into
the enclosure from outside.
3) Measures against condensation
Condensation may occur if frequent operation stops change the in-enclosure temperature suddenly or if the outside-
air temperature changes suddenly.
Condensation causes such faults as reduced insulation and corrosion.
Take the measures against high humidity in 1).
Do not power off the inverter. (Keep the start signal of the inverter off.)
8
Installation of the inverter and enclosure design
(3) Dust, dirt, oil mist
Dust and dirt will cause such faults as poor contact of contact points, reduced insulation or reduced cooling effect due to
moisture absorption of accumulated dust and dirt, and in-enclosure temperature rise due to clogged filter. In the atmosphere
where conductive powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in
a short time.
Since oil mist will cause similar conditions, it is necessary to take adequate measures.
Countermeasures
Place in a totally enclosed enclosure.
Take measures if the in-enclosure temperature rises. (Refer to page 10)
Purge air.
Pump clean air from outside to make the in-enclosure pressure higher than the outside-air pressure.
(4) Corrosive gas, salt damage
If the inverter is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or the
relays and switches will result in poor contact.
In such places, take the measures given in Section 3.
(5) Explosive, flammable gases
As the inverter is non-explosion proof, it must be contained in an explosion proof enclosure. In places where explosion may be
caused by explosive gas, dust or dirt, an enclosure cannot be used unless it structurally complies with the guidelines and has
passed the specified tests. This makes the enclosure itself expensive (including the test charges). The best way is to avoid
installation in such places and install the inverter in a non-hazardous place.
(6) Highland
Use the inverter at the altitude of within 1000m (3280.80 feet). If it is used at a higher place, it is likely that thin air will reduce
the cooling effect and low air pressure will deteriorate dielectric strength.
Maximum 1000m (3280.80feet) above sea level for standard operation. After that derate by 3% for every extra 500m
(1640.40feet) up to 2500m (8202feet) (91%).
(7) Vibration, impact
The vibration resistance of the inverter is up to 5.9m/s2 at 10 to 55Hz frequency and 1mm amplitude. Vibration or impact, if
less than the specified value, applied for a long time may make the mechanism loose or cause poor contact to the connectors.
Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to break.
Countermeasures
Provide the panel with rubber vibration isolators.
Strengthen the structure to prevent the enclosure from resonance.
Install the enclosure away from sources of vibration.

Installation of the inverter and enclosure design
1.4.2Cooling system types for inverter enclosure
From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformers, lamps, resistors,
etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature lower than the
permissible temperatures of the in-panel equipment including the inverter.
The cooling systems are classified as follows in terms of the cooling calculation method.
1) Cooling by natural heat dissipation from the enclosure surface (totally enclosed type)
2) Cooling by heat sink (aluminum fin, etc.)
3) Cooling by ventilation (forced ventilation type, pipe ventilation type)
4) Cooling by heat exchanger or cooler (heat pipe, cooler, etc.)

(3) Inverter mounting orientation
Mount the inverter on a wall as specified. Do not mount it horizontally or any other way.
(4) Above inverter
Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter should be
heat resistant.

Installation of the inverter and enclosure design
(5) Arrangement of multiple inverters
When multiple inverters are placed in the same
enclosure, generally arrange them horizontally as shown
in the right figure (a). When it is inevitable to arrange
them vertically to minimize space, take such measures as
to provide guides since heat from the bottom inverters
can increase the temperatures in the top inverters,
causing inverter failures.
When mounting multiple inverters, fully take caution not
to make the surrounding air temperature of the inverter
higher than the permissible value by providing ventilation
and increasing the enclosure size.
(6) Arrangement of ventilation fan and inverter
Heat generated in the inverter is blown up from the bottom of
the unit as warm air by the cooling fan. When installing a
ventilation fan for that heat, determine the place of ventilation
fan installation after fully considering an air flow. (Air passes
through areas of low resistance. Make an airway and airflow
plates to expose the inverter to cool air.)

To prevent a malfunction caused by noise, separate the signal cables more than 10cm (3.94inches) 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.

WIRING
The line voltage drop can be calculated by the following formula:
Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque
reduction) in the low speed range.

Main circuit terminal specifications
(2) Earthing (Grounding) precautions
Always earth (ground) the motor and inverter.
1) Purpose of earthing (grounding)
Generally, an electrical apparatus has an earth (ground) terminal, which must be connected to the ground before use.
An electrical circuit is usually insulated by an insulating material and encased. However, it is impossible to manufacture
an insulating material that can shut off a leakage current completely, and actually, a slight current flow into the case.
The purpose of earthing (grounding) the case of an electrical apparatus is to prevent operator from getting an electric
shock from this leakage current when touching it.
To avoid the influence of external noises, this earthing (grounding) is important to audio equipment, sensors, computers
and other apparatuses that handle low-level signals or operate very fast.
2) Earthing (grounding) methods and earthing (grounding) work
As described previously, earthing (grounding) is roughly classified into an electrical shock prevention type and a noise-
affected malfunction prevention type. Therefore, these two types should be discriminated clearly, and the following
work must be done to prevent the leakage current having the inverter's high frequency components from entering the
malfunction prevention type earthing (grounding):
(a)Where possible, use independent earthing (grounding) for the inverter. If independent earthing (grounding) (I) is
impossible, use joint earthing (grounding) (II) where the inverter is connected with the other equipment at an
earthing (grounding) point. Joint earthing (grounding) as in (III) must be avoided as the inverter is connected with the
other equipment by a common earth (ground) cable.
Also a leakage current including many high frequency components flows in the earth (ground) cables of the inverter
and inverter-driven motor. Therefore, they must use the independent earthing (grounding) method and be separated
from the earthing (grounding) of equipment sensitive to the aforementioned noises.
In a tall building, it will be a good policy to use the noise malfunction prevention type earthing (grounding) with steel
frames and carry out electric shock prevention type earthing (grounding) in the independent earthing (grounding)
method.
(b)This inverter must be earthed (grounded). Earthing (Grounding) must conform to the requirements of national and
local safety regulations and electrical codes. (NEC section 250, IEC 536 class 1 and other applicable standards).
Use an neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard.
(c)Use the thickest possible earth (ground) cable. The earth (ground) cable should be of not less than the size indicated
in the table on the previous page 17.
(d)The earthing (grounding) point should be as near as possible to the inverter, and the earth (ground) cable length
should be as short as possible.
(e)Run the earth (ground) cable as far away as possible from the I/O wiring of equipment sensitive to noises and run
them in parallel in the minimum distance.

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.(Refer to page 83)
NOTE
Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray
capacitances of the wiring, leading to a malfunction of the overcurrent protective function, fast response current limit
function, or stall prevention function or a malfunction or fault of the equipment connected on the inverter output side.
If malfunction of fast-response current limit function occurs, disable this function. If malfunction of stall prevention
function occurs, increase the stall level. (Refer to page 79 for Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention
operation selection )
Refer to page 148 for details of Pr. 72 PWM frequency selection. Refer to the manual of the option for details of surge

2.3.2Changing the control logic
NOTE
Fully make sure that the front cover has been reinstalled securely.
The capacity plate is placed on the front cover and the rating plate is on the inverter. Since these plates have the
same serial numbers, always reinstall the removed cover onto the original inverter.
The sink-source logic change-over jumper connector must be fitted in only one of those positions. If it is fitted in both
positions at the same time, the inverter may be damaged.
The input signals are set to sink logic (SINK) when shipped from
the factory.
To change the control logic, the jumper connector above the
control terminal must be moved to the other position.
Change the jumper connector in the sink logic (SINK) position
to source logic (SOURCE) position using tweezers, a pair of
long-nose pliers etc. Change the jumper connector position
before switching power on.

Wiring
Use a bar 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 bar terminal or the single wire into a socket of the terminal.
1) Strip off the sheath about the size 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 stripping size
Wire the stripped wire after twisting it to prevent it from
10mm
(0.39 inch)
becoming loose. In addition, do not solder it.
2) Crimp the bar terminal.
Insert wires to a bar terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve.

EMC and leakage currents
3.1EMC and leakage currents
3.1.1Leakage currents and countermeasures
Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage current
flows. Since its value depends on the static capacitances, carrier frequency, etc., low acoustic noise operation at the
increased carrier frequency of the inverter will increase the leakage current. Therefore, take the following measures. Select
the earth leakage current breaker according to its rated sensitivity current, independently of the carrier frequency setting.
(1) To-earth (ground) leakage currents
Leakage currents may flow not only into the inverter's own line but also into the other lines through the earth (ground) cable,
etc. These leakage currents may operate earth (ground) leakage circuit breakers and earth leakage relays unnecessarily.
Suppression technique
If the carrier frequency setting is high, decrease the Pr. 72 PWM frequency selection setting.
Note that motor noise increases. Selecting Pr. 240 Soft-PWM operation selection makes the sound inoffensive.
By using earth leakage circuit breakers designed for harmonic and surge suppression in the inverter's own line and other
line, operation can be performed with the carrier frequency kept high (with low noise).
To-earth (ground) leakage currents
Take caution as long wiring will increase the leakage current. Decreasing the carrier frequency of the inverter reduces the
leakage current.
Increasig the motor capacity increases the leakage current. The leakage current of the 400V class is larger than that of
the 200V class.
(2) Line-to-line leakage currents
Harmonics of leakage currents flowing in static capacitances between the inverter output cables may operate the external
thermal relay unnecessarily. When the wiring length is long (50m (164.04feet) or more) for the 400V class small-capacity model
(FR-D740-160 or less), the external thermal relay is likely to operate unnecessarily because the ratio of the leakage current to
the rated motor current increases.

Use Pr. 9 Electronic thermal O/L relay.
If the carrier frequency setting is high, decrease the Pr. 72 PWM frequency selection setting.
Note that motor noise increases. Selecting Pr. 240 Soft-PWM operation selection makes the sound inoffensive.
To ensure that the motor is protected against line-to-line leakage currents, it is recommended to use a temperature
sensor to directly detect motor temperature.
Installation and selection of moulded case circuit breaker
Install a moulded case circuit breaker (MCCB) on the power receiving side to protect the wiring of the inverter input side.
Select the MCCB according to the inverter input side power factor (which depends on the power supply voltage, output
frequency and load). Especially for a completely electromagnetic MCCB, one of a slightly large capacity must be selected
since its operation characteristic varies with harmonic currents. (Check it in the data of the corresponding breaker.) As an
earth leakage current breaker, use the Mitsubishi earth leakage current breaker designed for harmonics and surge
suppression.

(3) Selection of rated sensitivity current of earth (ground) leakage current breaker
When using the earth leakage current breaker with the inverter circuit, select its rated sensitivity current as follows,
independently of the PWM carrier frequency.
Some electromagnetic noises enter the inverter to malfunction it and others are radiated by the inverter to malfunction
peripheral devices. Though the inverter is designed to have high immunity performance, it handles low-level signals, so it
requires the following basic techniques. Also, since the inverter chops outputs at high carrier frequency, that could generate
electromagnetic noises. If these electromagnetic noises cause peripheral devices to malfunction, EMI measures should be
taken to suppress noises. These techniques differ slightly depending on EMI paths.
(1) Basic techniques
Do not run the power cables (I/O cables) and signal cables of the inverter in parallel with each other and do not bundle
them.
Use twisted shield cables for the detector connecting and control signal cables and connect the sheathes of the shield
cables to terminal SD.
Earth (Ground) the inverter, motor, etc. at one point.
(2) Techniques to reduce electromagnetic noises that enter and malfunction the inverter (Immunity measures)
When devices that generate many electromagnetic noises (which use magnetic contactors, magnetic brakes, many relays,
for example) are installed near the inverter and the inverter may be malfunctioned by electromagnetic noises, the following
measures must be taken:
Provide surge suppressors for devices that generate many electromagnetic noises to suppress electromagnetic noises.
Fit data line filters (page 41) to signal cables.
Earth (Ground) the shields of the detector connection and control signal cables with cable clamp metal.
(3) Techniques to reduce electromagnetic noises that are radiated by the inverter to malfunction peripheral devices (EMI
measures)
Inverter-generated electromagnetic noises are largely classified into those radiated by the cables connected to the inverter
and inverter main circuits (I/O), those electromagnetically and electrostatically induced to the signal cables of the peripheral
devices close to the main circuit power supply, and those transmitted through the power supply cables.

Propagation PathMeasures
When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g.
instruments, receivers and sensors, are contained in the enclosure that contains the inverter or when their signal
cables are run near the inverter, the devices may be malfunctioned by air-propagated electromagnetic noises. The
following measures must be taken:
(1)(2)(3)
(4)(5)(6)
(7)
(8)
Install easily affected devices as far away as possible from the inverter.
Run easily affected signal cables as far away as possible from the inverter and its I/O cables.
Do not run the signal cables and power cables (inverter I/O cables) in parallel with each other and do not bundle them.
Insert common mode filters into I/O and capacitors between the input lines to suppress cable-radiated noises.
Use shield cables as signal cables and power cables and run them in individual metal conduits to produce further effects.
When the signal cables are run in parallel with or bundled with the power cables, magnetic and static induction noises
may be propagated to the signal cables to malfunction the devices and the following measures must be taken:
Install easily affected devices as far away as possible from the inverter.
Run easily affected signal cables as far away as possible from the I/O cables of the inverter.
Do not run the signal cables and power cables (inverter I/O cables) in parallel with each other and do not bundle them.
Use shield cables as signal cables and power cables and run them in individual metal conduits to produce further effects.
When the power supplies of the peripheral devices are connected to the power supply of the inverter in the same line,
inverter-generated noises may flow back through the power supply cables to malfunction the devices and the
following measures must be taken:
Install the common mode filter (FR-BLF, FR-BSF01) to the power cables (output cable) of the inverter.
When a closed loop circuit is formed by connecting the peripheral device wiring to the inverter, leakage currents may
flow through the earth (ground) cable of the inverter to malfunction the device. In such a case, disconnection of the
earth (ground) cable of the device may cause the device to operate properly.

3.1.3Power supply harmonics
The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power capacitor
etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path.
Take the following countermeasure suppression techniques.
The differences between harmonics and RF noises are indicated below:

NOTE
The power factor improving capacitor and surge suppressor on the inverter output side may be overheated or damaged
by the harmonic components of the inverter output. Also, since an excessive current flows in the inverter to activate
overcurrent protection, do not provide a capacitor and surge suppressor on the inverter output side when the motor is
driven by the inverter. For power factor improvement, install a reactor on the inverter input side or in the DC circuit.

Installation of power factor improving reactor
3.2Installation of power factor improving reactor
When the inverter is connected near a large-capacity power transformer (500kVA or more) or when a power capacitor is to be
switched over, an excessive peak current may flow in the power input circuit, damaging the converter circuit. To prevent this,
always install an optional reactor (FR-HAL, FR-HEL).

PRECAUTIONS FOR USE OF THE INVERTER
Power-off and magnetic contactor (MC)
r
3.3Power-off and magnetic contactor (MC)
(1) Inverter input side magnetic contactor (MC)
On the inverter input side, it is recommended to provide an MC for the following purposes.
(Refer to page 4 for selection.)
1) To release the inverter from the power supply when the fault occurs or when the drive is not functioning (e.g. emergency
stop operation). When cycle operation or heavy-duty operation is performed with an optional brake resistor connected,
overheat and burnout of the discharging resistor can be prevented if a regenerative brake transistor is damaged due to
insufficient heat capacity of the discharging resistor and excess regenerative brake duty.
2) To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power failure
3) The control power supply for inverter is always running and consumes a little power. When stopping the inverter for an
extended period of time, powering off the inverter will save power slightly.
4) To separate the inverter from the power supply to ensure safe maintenance and inspection work.
The inverter's input side MC is used for the above purpose, select class JEM1038-AC3 MC for the inverter input side
current when making an emergency stop during normal operation.
REMARKS
Since repeated inrush currents at power on will shorten the life of the converter circuit (switching life is about 1,000,000 times.),
frequent starts and stops of the MC must be avoided. Turn on/off the inverter start controlling terminals (STF, STR) to run/stop the
inverter.
Inverter start/stop circuit example
As shown on the left, always use the start signal
(ON or OFF across terminals STF or STR-SD) to
make a start or stop.

(2) Handling of inverter output side magnetic contactor
Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop. When the
magnetic contactor is turned on while the inverter is operating, overcurrent protection of the inverter and such will activate.
When an MC is provided for switching to the commercial power supply, for example, switch it on/off after the inverter and
motor have stopped.

Inverter-driven 400V class motor
3.4Inverter-driven 400V class motor
In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a
400V class motor, the surge voltage may deteriorate the insulation. When the 400V class motor is driven by the inverter,
consider the following measures:
Measures
It is recommended to take either of the following measures:
(1)Rectifying the motor insulation and limiting the PWM carrier frequency according to the wiring
length
For the 400V class motor, use an insulation-enhanced motor.
Specifically,
1) Specify the "400V class inverter-driven insulation-enhanced motor".
2) For the dedicated motor such as the constant-torque motor and low-vibration motor, use the "inverter-driven, dedicated
motor".
3) Set Pr. 72 PWM frequency selection as indicated below according to the wiring length

(2) Suppressing the surge voltage on the inverter side
Connect the surge voltage suppression filter (FR-ASF-H/FR-BMF-H) on the inverter output side.

PRECAUTIONS FOR USE OF THE INVERTER
Precautions for use of the inverter
3.5Precautions for use of the inverter
The FR-D700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may
shorten the product life or damage the product.
Before starting operation, always recheck the following items.
(1) Use crimping terminals with insulation sleeve to wire the power supply and motor.
(2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring.
(3) After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.
When drilling mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the
inverter.
(4) Use cables of the size to make a voltage drop 2% maximum.
If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque
to decrease especially at the output of a low frequency.
Refer to page 17 for the recommended wire sizes.
(5) The overall wiring length should be 500m (1640.42feet) maximum.
Especially for long distance wiring, the fast-response current limit function may decrease or the equipment connected to
the secondary side may malfunction or become faulty under the influence of a charging current due to the stray capacity
of the wiring. Therefore, note the overall wiring length. (Refer to page 19)
(6) Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the
communication devices (such as AM radios) used near the inverter. In this case, install the FR-BIF optional capacitor
type filter (for use in the input side only) or FR-BSF01 or FR-BLF common mode filter to minimize interference.
(7) Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side.
This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are
connected, immediately remove them. (When using capacitor type filter (FR-BIF) for single-phase power supply
specification, make sure of secure insulation of T/L3-phase, and connect to the input side of the inverter.)
(8) For some short time after the power is switched off, a high voltage remains in the smoothing capacitor. When accessing
the inverter for inspection, wait for at least 10 minutes after the power supply has been switched off, and then make sure
that the voltage across the main circuit terminals P/+ and N/- of the inverter is not more than 30VDC using a tester, etc.
The capacitor is charged with high voltage for some time after power off and it is dangerous.
(9) A short circuit or earth (ground) fault on the inverter output side may damage the inverter modules.
Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits caused by
peripheral circuit inadequacy or an earth (ground) fault caused by wiring inadequacy or reduced motor insulation
resistance may damage the inverter modules.
Fully check the to-earth (ground) insulation and phase to phase insulation of the inverter output side before power-on.
Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance etc.
(10) Do not use the inverter input side magnetic contactor to start/stop the inverter.
Always use the start signal (turn on/off STF and STR signals) to start/stop the inverter. (Refer to page 44)
(11) Across P/+ and PR terminals, connect only an external regenerative brake discharging resistor.
Do not connect a mechanical brake.
The brake resistor can not be connected to the FR-D720-008 and 014 and FR-D720S-008 and 014. Never short
between terminals P/+ and PR.
46
Precautions for use of the inverter
(12) Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.
Application of a voltage higher than the permissible voltage to the inverter I/O signal circuits or opposite polarity may
damage the I/O devices. Especially check the wiring to prevent the speed setting potentiometer from being connected
incorrectly to short terminals 10-5.
(13) Provide electrical and mechanical interlocks for MC1 and MC2
which are used for bypass operation. When the wiring is
incorrect and if there is a bypass operation circuit as shown
right, the inverter will be damaged due to arcs generated at the
time of switch-over or chattering caused by a sequence error.
(14) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in the
inverter's input side and also make up a sequence which will not switch on the start signal.
If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as the
power is restored.
(15) Instructions for overload operation
When performing operation of frequent start/stop of the inverter, rise/fall in the temperature of the transistor element of
the inverter will repeat due to a repeated flow of large current, shortening the life from thermal fatigue. Since thermal
fatigue is related to the amount of current, the life can be increased by reducing current at locked condition, starting
current, etc. Decreasing current may increase the life. However, decreasing current will result in insufficient torque and
the inverter may not start. Therefore, choose the inverter which has enough allowance for current (up to 2 rank larger in
capacity).
(16) Make sure that the specifications and rating match the system requirements.

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).

PRECAUTIONS FOR USE OF THE INVERTER
Failsafe of the system which uses the inverter
3.6Failsafe 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 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.

1) Check by the inverter fault output signal
When the fault occurs and the inverter trips, the fault output
signal (ALM signal) is output (ALM signal is assigned to
terminal ABC in the initial setting).
Check that the inverter functions properly.
In addition, negative logic can be set (on when the inverter is
normal, off when the fault occurs).
2) Checking the inverter operating status by the inverter
operation ready completion signal
Operation ready signal (RY signal) is output when the
inverter power is on and the inverter becomes operative.
Check if the RY signal is output after powering on the
inverter.
3) Checking the inverter operating status by the start signal
input to the inverter and inverter running signal.
The inverter running signal (RUN signal) is output when the
inverter is running (RUN signal is assigned to terminal RUN
in the initial setting).
Check if RUN signal is output when inputting the start signal
to the inverter (forward signal is STF signal and reverse
signal is STR signal). For logic check, note that RUN signal
is output for the period from the inverter decelerates until
output to the motor is stopped, configure a sequence
considering the inverter deceleration time.

4) Checking the motor operating status by the start signal input to the inverter and inverter output current detection signal.
The output current detection signal (Y12 signal) is output when the inverter operates and currents flows in the motor.
Check if Y12 signal is output when inputting the start signal to the inverter (forward signal is STF signal and reverse
signal is STR signal). Note that the current level at which Y12 signal is output is set to 150% of the inverter rated current
in the initial setting, it is necessary to adjust the level to around 20% using no load current of the motor as reference with
Pr.150 Output current detection level.
For logic check, as same as the inverter running signal (RUN signal), the inverter outputs for the period from the inverter
decelerates until output to the motor is stopped, configure a sequence considering the inverter deceleration time.

NOTE
Changing the terminal assignment using Pr. 190, Pr. 192 (output terminal function selection) may affect the other functions.
Make setting after confirming the function of each terminal.
(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.

NOTE
The amount of current flows in the motor may become large according to the conditions such as the motor
characteristics, load, acceleration/deceleration time, wiring length, etc., resulting in an overcurrent trip (OL (overcurrent
alarm) then E.OC1 (overcurrent trip during acceleration), overload trip (E.THM (motor overload trip), or E.THT (inverter
overload trip).
(When a fault occurs, release the start command, and decrease the Pr. 0 setting 1% by 1% to reset.) (Refer to page 248.)
The Pr. 0, Pr. 46 settings are valid only when V/F control is selected.

General-purpose magnetic flux vector control is available.
Large starting torque and low speed torque are available with General-purpose magnetic flux vector control.
What is General-purpose magnetic flux vector control ?
The low speed torque can be improved by providing voltage compensation to flow a motor current which meets the
load torque. With setting slip compensation (Pr. 245 to Pr. 247), output frequency compensation (slip compensation) is
made so that the actual motor speed goes closer to a speed command value. Effective when load fluctuates
drastically, etc.
General-purpose magnetic flux vector control is the same function as the FR-E500 series.

POINT
If the following conditions are not satisfied, select V/F control since malfunction such as insufficient torque and
uneven rotation may occur.
The motor capacity should be equal to or one rank lower than the inverter capacity. (note that the capacity
should be 0.1kW or more)
Motor to be used is any of Mitsubishi standard motor, high efficiency motor (SF-JR, SF-HR 0.2kW or more) or
Mitsubishi constant torque motor (SF-JRCA four-pole, SF-HRCA 0.4kW to 7.5kW). When using a motor other
than the above (other manufacturer's motor), perform offline auto tuning without fail.
Single-motor operation (one motor run by one inverter) should be performed.
The wiring length from inverter to motor should be within 30m (98.42feet). (Perform offline auto tuning in the
state where wiring work is performed when the wiring length exceeds 30m (98.42feet).)
Permissible wiring length between inverter and motor differs according to the inverter capacity and setting value
of Pr. 72 PWM frequency selection (carrier frequency). Refer to page 19 for the permissible wiring length.
(1) Control mode
V/F control (initial setting) and General-purpose magnetic flux vector control are available with this inverter.
V/F control is for controlling frequency and voltage so that the ratio of frequency (F) to voltage (V) is constant when
changing frequency.
General-purpose magnetic flux vector control divides the inverter output current into an excitation current and a torque
current by vector calculation, and makes voltage compensation to flow a motor current which meets the load torque.
(General-purpose magnetic flux vector control is the same function as the FR-E500 series.)

NOTE
Uneven rotation slightly increases as compared to the V/F control. (It is not suitable for machines such as grinding
machine and wrapping machine which requires less uneven rotation at low speed.)
When a surge voltage suppression filter (FR-ASF-H/FR-BMF-H) is connected between the inverter and motor, output
torque may decrease.
Adjust the output torque (current) of the motor
(3) Control method switching by external terminals (X18 signal)

control) with external terminal.
Turn the X18 signal on to change the currently selected control method (General-purpose magnetic flux vector control) to
V/F control.
For the terminal used for X18 signal input, set "18" in any of Pr. 178 to Pr. 182 (input terminal function selection) to assign the
function.
REMARKS
When V/F control is selected by V/F switchover (X18 signal), second function is also selected at the same time. Control between
V/F control and General-purpose magnetic flux vector control can not be switched while the inverter is running. In case control is
switched between V/F control and General-purpose magnetic flux vector control, only second function is selected.

4.3.4Stall prevention operation (Pr. 22, Pr. 23, Pr. 48, Pr. 66, Pr. 156, Pr. 157)
This function monitors the output current and automatically changes the output frequency to prevent the inverter from
coming to trip due to overcurrent, overvoltage, etc.
It can also limit stall prevention and fast-response current limit operation during acceleration/deceleration, driving or
regeneration.
Stall prevention
If the output current exceeds the stall prevention operation level, the output frequency of the inverter is
automatically changed to reduce the output current.
Fast-response current limit
If the current exceeds the limit value, the output of the inverter is shut off to prevent an overcurrent.

(3) Stall prevention operation signal output and output timing adjustment (OL signal, Pr. 157)
When the output current exceeds the stall prevention operation level and stall prevention is activated, the stall prevention
operation signal (OL signal) turns on for longer than 100ms. When the output current falls to or below the stall prevention
operation level, the output signal turns off.
Use Pr. 157 OL signal output timer to set whether the OL signal is output immediately or after a preset period of time.
This operation is also performed when the regeneration avoidance function or (overvoltage stall) is executed.

assign functions to the output terminal.

performed. Normally set this parameter to 150% (initial value).
When "Operation not continued for OL signal output" is selected, the fault (stopped by stall prevention) is displayed and operation is stopped.

REMARKS
In the initial setting, if two or three of multi-speed settings are simultaneously selected, priority is given to the set frequency of
the lower signal.
For example, when the RH and RM signals turn on, the RM signal (Pr. 5) has a higher priority.
The RH, RM, RL signals are assigned to the terminal RH, RM, RL in the initial setting. By setting "0 (RL)", "1 (RM)", "2 (RH)" in
any of Pr. 178 to Pr. 182 (input terminal function selection), you can assign the signals to other terminals.

REMARKS
The priorities of the frequency commands by the external signals are "Jog operation > multi-speed operation > terminal 4 analog
input > terminal 2 analog input".
(Refer to page 153 for the frequency command by analog input)
Valid in the external operation mode or PU/external combined operation mode (Pr. 79 = "3" or "4").
Multi-speed parameters can also be set in the PU or external operation mode.
Pr. 24 to Pr. 27 and Pr. 232 to Pr. 239 settings have no priority between them.
When Pr. 59 Remote function selection ≠ "0", multi-speed setting is invalid as RH, RM and RL signals are remote setting signals.
NOTE
Changing the terminal assignment using Pr. 178 to Pr. 182 (input terminal function selection) may affect the other
functions. Make setting after confirming the function of each terminal.

Frequency setting by external terminals
(1) Remote setting function
Use Pr. 59 to select whether the remote setting function is used or not and whether the frequency setting storage function
in the remote setting mode is used or not.
When Pr. 59 is set to any of "1 to 3" (remote setting function valid), the functions of the RH, RM and RL signals are
changed to acceleration (RH), deceleration (RM) and clear (RL).
When using the remote setting function, following frequencies can be compensated to the frequency set by RH and RM
operation according to the operation mode.
During external operation (including
During external operation and PU combined operation (
During PU operation ...............................................................................PU frequency command
(2) Frequency setting storage
The frequency setting storage function stores the remotely-set frequency (frequency set by RH/RM operation) into the
memory (EEPROM). When power is switched off once, then on, operation is resumed with that output frequency value.
(Pr. 59 = 1)
<Frequency setting storage conditions>
Frequency at the point when the start signal (STF or STR) turns off
Remotely-set frequency is stored every minute after turning OFF (ON) the RH (acceleration) and RM(deceleration)
signals together. (The frequency is overwritten if the latest frequency is different from the previous frequency when
comparing the two. The state of the RH signal does not affect writing.)

The range of frequency changeable by RH

Note that the maximum value of set frequency
is (main speed + maximum frequency).

When the acceleration or deceleration signal switches ON, acceleration/deceleration time is as set in Pr. 44 Second
acceleration/deceleration time and Pr. 45 Second deceleration time. Note that when the time set in Pr. 7 or Pr. 8 is longer than
the time set in Pr. 44 or Pr. 45, the acceleration/deceleration time is as set in Pr. 7 or Pr. 8. (when RT signal is OFF)
When the RT signal is on, acceleration/deceleration is made in the time set in Pr. 44 and Pr. 45, regardless of the Pr. 7
or Pr. 8 setting.
Even if the start signal (STF or STR) is off, turning on the acceleration (RH) or deceleration (RM) signal varies the
preset frequency. (When Pr. 59 = "1" or "2")
When switching the start signal from ON to OFF, or changing frequency by the RH or RM signal frequently, set the
frequency setting value storage function (write to EEPROM) invalid (Pr. 59 = "2, 3"). If set valid (Pr. 59 = "1"), frequency
is written to EEPROM frequently, this will shorten the life of the EEPROM.
The RH, RM, RL signals can be assigned to the input terminal using any Pr. 178 to Pr. 182 (input terminal function
selection). When terminal assignment is changed, the other functions may be affected. Please make setting after
confirming the function of each terminal.
