Features
Advanced Mitsubishi Technology Creates a Winner
Highly Cost-Effective and Very Powerful
■ High Torque (150 %) at Speeds as Low as 1Hz.
Mitsubishi has achieved a 1Hz 150% torque by combining slip compensation with its original general-purpose flux vector control. Operation
can be controlled by general-purpose flux vector control even when motor characteristics vary simply by using the off-line auto-tuning function.
Sample speed-torque characteristics when general-purpose flux vector control
and slip compensation are selected (with an SF-JR 4P 0.75kW motor)

■ A Brake Resistor can be Connected (0.4K and above).
■ High Response Current Limit.
Thanks to the high-response current limit function, there are fewer trips caused by overcurrent. It even handles instant peak currents when
starting during reverse coasting.
■ Now with a Higher Output Current Rating.
More powerful thanks to the highest output current rating in its class.

control panel as standard. Variable speed operation is available
soon after power is turned on. The control panel is removable,
so you can install it on a main control panel with optional
equipment and “off-the-shelf ” cables. The knob itself is
removable. You can also operate it remotely using parameter
settings and externally input frequency setting signals.
■ Height is Now Standardized
All models from 0.1 to 3.7kW are the same 128mm in height. This
makes panel layout easier. (Except FR-E540)
■ The Parameter Unit
● The FR-PU04 is another option available. It takes direct input
from a key pad. It uses a long-life backlit LCD and allows you to
copy parameters. Eight languages are available ( Japanese,
English, German, French, Spanish, Italian, Swedish, and Finnish).
Connect it with the separately sold cable.
FR-PU04 parameter unit (option)
● We've made parameter user group functions as standard. You can
select just the parameters you need for writing and reading to
simplify parameter management.
● You can use the setup software for parameter settings. We've
provided optional software that lets you use a personal computer
to assist you in everything from starting up the inverter to
maintenance.
■ Easy to Maintain
● Easy access makes changing the cooling fan very simple. Operating
life can also be increased by turning ON-OFF control on.
■ Easy to Wire
● A screwed terminal plate is used for the main circuit.
● A screwed terminal plate is also used for the all new control

Notes:
1. The applied motor shown is the maximum application capacity when a standard
four-pole Mitsubishi motors is used.
2. The rated output capacity is for a 230V output voltage.
3. After operation in the overload region, care should be taken to make sure that
standard operating conditions are once again met.
4. The maximum output voltage should not exceed the power supply voltage. Any
voltage less than that can be set as the maximum output voltage. The exception is
the FR-E510W series.
5. The power supply capacity will vary with the value of the power supply impedance
(including the input reactor and power lines).

(PWM frequency selection) set to 2kHz or more when the ambient temperature is 40°C
(30°C for IP40 construction) or higher.
7. When using a DC power supply:
(1) Use DC 280V ±10% as a guide for the supply voltage fluctuation range and try
to keep voltage at 300V DC or less.
(2) There is a larger surge current when the power is turned on compared with an
AC power supply. Keep the number of “on-offs” to a minimum.
(3) Ensure a voltage of DC 300V to keep torque characteristics the same as with an
AC power supply.
8. Please refer to the sequencer side specifications below for information on the

Notes: 1. The indicated control torque size is the short-term average torque (which changes with motor loss) when decelerated at maximum rate from 60Hz when the motor
is operated alone. It is not continuous regenerative torque. Deceleration from frequencies in excess of the base frequency will have lower average deceleration
torque values. The inverters have no built-in brake resistors, so when the regenerative energy is high, use the optional brake resistor. A BU model brake unit may
also be used (except with 0.1K and 0.2K models). The control torque when a brake resistor is used is shown on page 41; the same for when a brake unit is used
is shown on page 36.
2. Temperature to which units can be exposed for a short time, such as during transportation.
3. When an insufficient voltage or instantaneous power failure occurs, error display and output do not work, but the inverter is protected. Depending on the operating
status (e.g., the size of the load),. Overcurrent protection, regenerative overvoltage protection etc. may engage upon restoration of power.

Description of Terminal Specifications
Model type
Terminal symbol
Main circuit
Connected to the commercial power supply. When using a DC power input for units with 3-phase power input
specifications, please connect it across terminals R (L1) and S (L2). When using a high power factor converter
(FR-HC), do not connect anything.
U, V, W
Inverter output
Connects the 3-phase squirrel cage motor.
P, PR
(+, PR)
Brake resistor connection
This terminal is used to connect the optional dedicated brake resistor (cannot be connected to the 0.1K and
0.2K models).
Brake unit connection
Connect the optional brake unit and high power factor converter to these terminals.
Power factor improvement
DC reactor connection Remove the short bar between terminals P (+) and P1 and connect the optional power
factor improvement DC reactor (FR-BEL).
Ground (Earth)
This is for grounding the inverter chassis. Always ground the inverter.
STF
Forward run start
Serves as the forward run command when terminals STF-SD are ON.
STR
Reverse run start
Serves as the reverse run command when terminals STR-SD are ON.
Multi-speed selection
The multi-speed type can be selected with a combination of shorts between
the terminals RH, RM and RL-SD.
MRS
Output stop
Inverter output stops when terminals MRS-SD are shorted (for 20ms or
more). This is used to cut off the inverter output when stopping the motor
with a magnetic brake.
RES
Reset
This is used to cancel the hold state when the protection circuit activates. Turn ON terminals RES-SD for
0.1 second or more, and then turn them OFF.
SD
Contact input common
This is the common terminal for the contact input terminal and the display meter (Note 4).
PC
External transistor common
When connecting a transistor output (open collector output) such as a programmable logic controller (PLC),
malfunctions caused by supplied current can be prevented by connecting the external power common for the
transistor output to this terminal. It is possible to use 24V DC 0.1A as the power supply.

Frequency setting (voltage)
When 0 to 5V DC (or 0 to 10V) is input, the maximum output frequency is reached at 5V (10V). The input and
output are proportional. 5V DC and 10V DC are changed using Pr. 73 (See page 23). Input resistance is 10kΩ;
tolerable input voltage is 20V.

5
Frequency setting input
common
This is the common terminal for the frequency setting signal (Note 4).
Do not ground this common.
–
4
Frequency setting
(current signal)
Input 4 to 20mA DC. The maximum output frequency is reached at 20mA. At shipment, the inverter is adjusted
so that 4mA gives 0Hz and 20mA gives 60Hz. The maximum tolerable current is 30mA; the input resistance
is approximately 250Ω.
–
P24
Contact input
common (source)
Common terminal for contact inputs when using source input. When using source input, turn signals ON
by shorting to this terminal or OFF by leaving it open.
Alarm output
This is a contact output that indicates that the inverter's protection circuit has
functioned and the output has stopped. 200V AC 0.3A or 30V DC 0.3A. When an
alarm occurs, there is non-continuity between B-C (continuity between A-C); in normal
operations, there is continuity between B-C (non-continuity between A-C).
Inverter running
L level is output when the inverter output frequency is higher than the starting
frequency (the default of 0.5Hz is changeable); H level is output when stopped or
during DC braking (Note 1). Tolerable load: 24V DC 0.1A.
FU
Frequency detection
L level is output when the output frequency is higher than the set detection
frequency; H level is output when it is lower (Note 1). Tolerable load: 24V DC 0.1A.
–
SE
Open collector output
common
This is the common terminal for the terminals RUN and FU (Note 4).
–
FM
For display meter
When shipped, the inverter is set so that when terminals FM-SD are opened, 60Hz gives about 5V and output
frequency is proportional. The output voltage is a pulse waveform, so a digital display meter can be connected.
Pulse specification: 1440 pulse/sec. at 60Hz.

This indicates a parameter whose setting is ignored when general-purpose flux vector control mode is selected.
The set values for the parameters in the shaded areas can be altered during operations even if Pr.77 (
Parameter write disable) is set to 0 (default setting).
Even if Pr.77 (Parameter write disable) is set to 2, the set value cannot be changed during operations.
Since they are calibrated before shipment, settings will vary slightly from inverter to inverter. Some are set to a frequency is slightly higher than 60Hz.
Some of the names of CC-Link Series functions differ from those of frequency setting volume type functions.
: Applicable. – : Not applicable.
The setting depends on the inverter capacity: (0.1K to 3.7K) / (5.5K to 7.5K)
The ground fault detection setting parameter is not applicable to the FR-E540 series.
The FR-E540 series is automatically set to detect ground faults.
9. The setting for the FR-E540-5.5K / 7.5K is 4%.

● Any base frequency (the reference frequency at the motor's rated

● Motors rated at below the inverter's power supply voltage are best
used by setting Pr.19 (base frequency voltage). This is convenient
when using, for example, a 200V rated motor with a 230V power
supply.

Notes: 1. When Pr.24–Pr.27 and Pr.232–Pr.239 are set to 9999 (default setting),
4 –7 and 8 –15 cannot be selected (or run).
2. Multi-speed settings have priority over analog input commands
(between terminals 2 and 5 or 4 and 5).
3. Multi-speed settings can be done during PU operation or external operation.
4. For three-speed settings (when Pr.24–Pr.27 and Pr.232–Pr.239 are not set),
selection of two or more speeds simultaneously will set the speed to the
speed set at the low speed signal terminal.
5. Terminals used for REX signal input are assigned by Pr.180 –Pr.183

the time required to reach 0Hz from the setting of Pr.20.
● Pr. 21 (acceleration/deceleration time increments) allows you to
set the setting range and the minimum setting increment. A
setting of 0 provides a range 0–3600sec. (minimum increment of
0.1sec.); a setting of 1 provides a range of 0 –360 sec. (minimum

current value (A). Normally, the rated motor current for 50Hz is
set. This provides the optimum protection characteristics for low
speed operations, including when motor cooling power drops
during low-speed operation.
When 0A is set, the motor protection function does not engage.
(The inverter’s output transistor protection function does.)
When using a Mitsubishi fixed torque motor, set Pr.71 (applied
motor) to 1, 13, 15, or 16, select the 100 % continuous torque
characteristics at low speed, and set the motor’s rated current in
Pr. 9 (electronic thermal O/L relay).
The factory default setting is the inverter’s rated output current,
except for 0.1–0.75K inverters, for which it is 85% of the
inverter’s rated current.
When several motors are operated simultaneously, install an
external thermal relay on each motor.

You can select the best pattern for your application.
● Setting 0 (linear acceleration/deceleration): The most common
acceleration/deceleration pattern. Normally, you should use this
setting.
● Setting 1 (S-curve acceleration/deceleration A): Use this pattern
when you need acceleration/deceleration in a short time frame in
high-speed zones of 60Hz and above. In this acceleration/
deceleration pattern, fb (the base frequency) is the inf lection
point. You can set the acceleration/deceleration time to match
the reduction in motor torque in fixed output operation zones of
60 Hz and above. It is suited for applications such as main axes of
machine tools.
● Setting 2 (S-curve acceleration/deceleration B): Because it
always accelerates/decelerates in an S-curve between f2 (current

Description
You can change between PU operation mode and external operation

columns for values 1 and 2 for the descriptions of the modes.
Notes: General-purpose flux vector control can be used with the following restrictions.
1. The motor is a standard, general-purpose squirrel-cage motor whose
capacity (0.1 kW or higher) is equal to or less than the inverter capacity.
In the fixed torque motor (SF-JRCA) 200V class 4P, it can be used with
0.4–3.7kW motors.
2. The motor has 2, 4, or 6 poles. (Fixed torque motors must have four
poles.) There is no need to set the number of poles.
3. The motor must be used alone (one inverter per motor).
4. The maximum wiring length between motor and inverter cannot exceed
30 m. Beyond 30 m, use off-line auto-tuning.
Usage under other conditions may not provide the best performance.,
Note: This control system is not the same as the Mitsubishi advanced flux vector
control used in the FR-A500 Series inverters.

Protective Functions
The following protective functions are provided for the protection of the inverter itself (except for the motor's electronic thermal relay), but they
may also function when the inverter breaks down.
Type (Note 5)
Function name
Description
When the inverter output current exceeds the rated current by more than approximately
200% during acceleration/deceleration or at constant speed, the protective circuit activates,
halting inverter output.
Over-current shut-off
Regenerative overvoltage
shut-off
If the DC voltage in the inverter's internal main circuit exceeds the rated value as a result
of regenerative energy generated through motor braking during acceleration/deceleration
or at constant speed, the protective circuit activates, halting inverter output. There are also
cases where it is activated by surge voltage generated in the power supply system.

●
●
Motor
The electronic overcurrent protection inside the inverter detects motor overheating resulting from overloading
or a decline in cooling capacity at constant speed, activating the protective circuit and halting inverter output.
The electronic thermal relay cannot protect multipolar and other special motors, or several motors working
together, so a thermal relay should be installed on the inverter's output side.
(THM)
●
Inverter
In the case where a current flows that is at least 150% of the rated output current but does not exceed the
overcurrent shut-off (OC) level (200% max.), the electronic thermal relay activates according to reverse time
characteristics to protect the main circuit transistors, and halts inverter output. (150% of overload capacity,
60 seconds.)
(THT)
●
(FIN)
●
Overload shut-off
(electronic thermal
relay) (Note 1)
Fin overheat
If the cooling fin overheats, the fin overheat sensor activates and halts inverter output.
Fan breakdown
When the inverter has a built-in cooling fan, FN will be displayed on the control panel when the cooling fan
breaks down or an operation different from the setting of Pr.244 (cooling fan operation selection) is performed.
Inverter output does not stop.
(FN)
Output ground fault
overcurrent protection
When a ground fault occurs at the inverter output (the load side) when the inverter is started up and the
ground fault overcurrent flows, inverter output stops. Use Pr.249, “Ground fault detection at Startup (Y/N)”
to set whether to engage the protection function. (Note 8)
(GF)
●
External thermal relay
operation (Note 2)
When an externally installed motor overheating protective thermal relay or temperature relay within the motor,
etc., activates (relay contact open), the inverter can be stopped if the contact is input to the inverter. Even if
the relay contact resets automatically, the inverter will not restart unless it is reset also.
(OHT)
●
Brake transistor error
detected (Note 3)
When the optional brake resistor is connected and a brake transistor error occurs (for example, when the
energy regenerated from the motor becomes very large), this is judged a brake transistor error and inverter
output stops.
(BE)
●
Parameter error
Generated when an error occurs in a stored parameter (e.g. E2ROM breakdown).
(PE)
●
PU disconnected
Inverter output halts when communication between the main unit and the PU is interrupted by disconnection
of the PU, etc., when Pr. 75 is set to 2, 3, 16, 17.

Number of retries exceeded
When operations cannot be restarted normally within the set number of retries, inverter output is halted.
Output phase loss detection
Detects when the inverter looses an output phase (U, V or W).
CPU error
If the built-in CPU does not complete operations within the prescribed time, it self-diagnoses a fault and halts
inverter output.
Current limit/
Stall prevention
During
acceleration
When a current of 150% (Note 4) or more of the inverter's rated current flows in the motor, the rise in frequency
is stopped until the load current declines, preventing the inverter from executing an over-current shut-off. The
frequency is increased again once the current falls below 150% of the rated value.

At constant
speed
When a current of 150% (Note 4) or more of the inverter's rated current flows in the motor, the frequency is

frequency is restored to the set level once the current falls below 150% of the rated value.
and monitor
displayed alternately.
During
deceleration
If the motor's regenerative energy is excessive and surpasses its braking capacity, the decline in frequency is
halted, preventing the inverter from executing an over-current shut-off. Once the regenerative energy has
declined, deceleration continues. When a current of 150% (Note 4) or more of the inverter's rated current flows
in the motor, the decline in frequency is halted until the load current declines, preventing the inverter from
executing an over-current shut-off. The frequency is lowered once again once the current falls below 150% of
the rated value.

When the inverter is reset, the internal heat counting data in the electronic thermal O/L relay (overcurrent protection) is initialized.
External thermal relay operations are only performed when Pr. 180 –Pr. 183 (input terminal function selection) is set to OH.
This only functions when the optional brake resistor is connected.
Any stall prevention operation current can be set. Set to 150% when shipped.
Major Breakdowns: Inverter output is cut off by the protection function and an error signal is output.
Minor Breakdowns: The protection function does not cut off output. A minor breakdown signal can be output if the parameter is set to do so.
6. In the case of the CC-Link Series, the ALARM lamp lights up the when the protection function activates. If parameter unit FR-PU04 is in use, its displays switches
automatically to indicate an error.
7. CC-Link Series only.
8. Pr.249 is not applicable to the FR-E540 series.
The FR-E540 series is automatically set to detect ground faults.

● Alarm output signal held........When the magnetic contactor (MC) provided on the power supply 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 control panel display automatically switches to the above indication.
● Resetting method....................When the protective function is activated, the inverter output is kept at a stop. Therefore, unless reset, the inverter cannot restart. Switch
power off once, then on again; or short reset terminal RES-SD for more than 0.1 second, then open. If RES-SD are kept shorted, "Err." appears
(flickers) to indicate that the inverter is being reset.

Notes: 1. Use mechanically interlocked magnetic contactors for MC1 and MC2.
2. Connect OCR to the commercial circuit side. If connected to the
inverter, it may be engaged unexpectedly by leakage current during
low noise operation. We recommend the electronic thermal O/L relay
function (Pr.9) for motor protection when the inverter is operating.

■ Multi-Speed Operation
(With Mitsubishi Programmable Controllers)
● This is a sample circuit for multi-speed operation with a
●
●
●
●
Mitsubishi programmable controller (with an AY40 transistor
output unit).
AY40 common pin 9 for preventing wrap-arounds must be
connected to inverter terminal PC.
You can select a variety of functions for the inverter's transistor
output signals (RUN, SU, etc.) using Pr.190 and Pr. 191 (output
terminal function selection). These inverter output signals,
however, must be received at an AX40 DC input unit.
Up to 15 speeds can be set with the multi-speed setter, but an
additional two speeds can be obtained by shorting terminals 10
and 2 for an upper limit frequency setting (Pr.1) and terminals 2
and 5 for a lower limit frequency setting (Pr.2).
For safety, install a magnetic contactor on the input side.

If you are using a leakage breaker in the inverter circuit, use the
following criteria to select a rated sensitivity current, regardless of
the carrier frequency.
•For the Progressive Super NV Series (models SP and CP):
Rated sensitivity current I n>10× (Ig2+Ign+Ig2+Igm)
•For the conventional NV series (models CA, CS, and SS):
Rated sensitivity current I n>10{Ig1+Ign+3×(Ig2+Igm)}
Ig1, Ig2: Leakage current when operating with a cable run off
a commercial power supply.

2. The lead size shown is for a wiring length of 20m.
3. Selection of the magnetic contactor at the inverter input side
will differ in the areas A, B, and C (as shown in the right
diagram) because of the power supply capacitance and wiring
length. For 0.4K to 1.5K, select an S-N10 when using a reactor
for improving the power factor (FR-BEL or FR-BAL).
4. When the inverter capacity exceeds the motor capacity, select
the breaker and magnetic contactor appropriate for the inverter
model and select the lead and reactor for improving the power
factor appropriate for the motor model.
5. There are occasions where goes slightly under 0.9.

Notes: 1. Install the NV on the primary side of the inverter the (power supply side).
2. Ground detection on the inverter's secondary side is possible if the
operating frequency is 120Hz or less.
3. If you are using the W connection neutral point grounding method, the
sensitivity current of the grounding at the inverter's secondary side will
slow down, so use a special class 3 ground (10Ω or less) for the
protection ground of the equipment under load.
* Consult the filter manufacturer for the leakage current value of the noise
filter installed at the inverter input side. (See pages 37 for the Mitsubishi
inverter filters.)

■ Noise
When making operation quieter by raising the carrier frequency,
electromagnetic noise tends to increase, so measures should be
taken to reduce it along the lines outlined below. Note that in some
installations, noise can be a factor even without the low noise
settings (i.e., at default settings).
● Noise levels can be reduced by decreasing the Pr.72 setting for
the carrier frequency.
● An FR-BIF radio noise filter can be effective against AM radio
broadcast noise.
Anti-Noise Measures
Control board
Reduce the carrier
frequency
● The FR-BSF01 line noise filter can be effective against malfunc-
tioning of sensors.
● Inductive noise in the inverter's cable runs can be reduced by
separating them 30cm (or at least 10cm) and using twisted pair
shielded cable. The shielded cable should not be grounded;
instead, connect them to one point on the common side of the
signals.

■ Leakage Current
There are electrostatic capacitances between the inverter's
input/output wiring and other wires and the earth and in the motor.
Leakage current flows through these. Since their values are affected
by the static caapcitances and carrier frequencies, leakage current

increases when operation is made quieter by increasing the
inverter's carrier frequency. This can be improved by the following
measures. Also, when selecting a leakage breaker, follow the
advice on page 32, regardless of the carrier frequency.
Effect and Response
● The leakage current between the inverter input and output lines and the earth flows
not just to the inverter system but also to other systems through the ground wires.
● Leakage breakers and relays may trip unnecessarily.
Response
● Lower the inverter’s carrier frequency (Pr. 72). Motor noise will increase, but the
noise can be made more pleasant by selecting Soft-PWM control (Pr. 240).
● Use of anti-harmonic and anti-surge components (such as Mitsubishi's New Super
NV Series) in the leakage breakers of the inverter system and other systems can
allow use of the low noise configuration (with the raised carrier frequency).
● Leakage current flows through the electrostatic capacitance between inverter output
lines.
● Externally connected thermal relays can be tripped unnecessarily by harmonics of
leakage currents.
Response
● Use the built-in electronic thermal protection in the inverter.
● Lower the inverter's carrier frequency (Pr.72). Motor noise will increase, but the
noise can be made more pleasant by selecting Soft-PWM control (Pr. 240).

● Handling Cautions
1. The thermal relay in the brake unit will trip if the rated
torque is continuously exceeded. After a trip, reset
the inverter and increase its deceleration time setting.
2. The maximum temperature rise for the discharging
resistor is 100˚C. Use heat resistant lead and wire
to avoid contact with resistors.

Notes: 1. Connect so the terminal symbols are the same for both inverter and brake.
Wrong connections can damage the inverter.
2. Keep the wiring between inverter and brake unit and between discharging
resistor and brake unit as short as possible. Use twisted leads for lengths
greater than 2 m. (Even twisted leads should not exceed 5 m.)

3. Keep wiring to the inverter within 5 m.
4. The lead used should be as large or larger than the power supply
lead (R, S, T (L1, L2, L3)). (See page 32.)
5. Select the reactor for the capacity of motor to be used from the
selecting peripherals table. (When the inverter capacity is greater,
match the motor capacity.)
6. For motors less than 0.4kW, select for 0.4kW. The power factor
will be somewhat less than 95%.

● Countermeasures Against Leakage Current
U
V
W
Leakage current can cause peripheral malfunctions and shocks, so take
the following countermeasures.
1. Ground the noise filter before connecting it to the power supply. At this
point, check that the connection to the earth through the ground of the
board is secure.
2. Include the noise filter's leakage current in your calculations when
selecting a leakage breaker and leakage relay. Also, since large noise
filters have large leakage currents, you may not always be able to use
leakage breakers. Either use a leakage relay with a high sensitivity
current or securely ground as described in item 1 if you cannot use a
leakage breaker or leakage relay.
Ground
Note: You will need an EMC filter mounting attachment (FR-E5T/
FR-E5T-02) to mount an inverter on the SF1309/SF1260.
Remember that the attachment will add additional depth.
* The SH1260 has ø7 mounting holes.

Notes:
1. Each phase should be wound at least 3 times (4T, 4 turns) in the same
direction. (The greater the number of turns, the more efficient.)
2. When the thickness of the wire prevents winding, use at least 4 in series
and ensure that the current passes through each phase in the same
direction.
3. Can be used on the output side in the same way as the input side. On the
output side, the number of turns should be less than 3 (4T, 4 turns).
4. Please use FR-BSF01 for inverters with small capacities of 3.7kW or less.
Thick wires (38mm2 or more) cannot be used. In such cases, use FR-BLF.

1. Always open the inverter's R, S, and T power supply input terminals. Wrong connections can damage the inverter. Both the high power
factor converter and the inverter can be damaged if the P and N terminals polarities are wrong.
2. Wire so that the R4, S4, and T4 terminals and the R, S, and T terminals match the power supply phases.
3. Check the connection order for reactors 1 and 2. Reactors produce heat if connected incorrectly.

Motor Applications
Application of Special Motors
■ Motors with Brakes
Use a motor with a brake that has an independent power supply for
the brake, connect the brake supply to the primary supply of the
inverter, use the output stop terminal (MRS) for braking (stopping
the motor), and turn the inverter output off. Depending on the type
of brake, there may be a clattering noise in the brake lining at low
speeds. This is not a malfunction.
■ Motors with a Variable Numbers of Poles
When the number of motor poles is convertible, the rated current
will differ from a standard motor, so check the motor's maximum
current when selecting an inverter. Be sure to stop the motor before
switching the number of poles. Switching on the fly will engage the
regenerative overvoltage protection circuit, trigger the inverter
alarm, and send the motor into a coasting stop.
■ Geared Motors
The ranges for continuous operation vary with both the lubrication
system used and the manufacturer. Oil lubricated motors are
particularly prone to burning of gears when operated exclusively at
low speeds. Consult the manufacturer before operating motors at
speeds in excess of 60Hz.
■ Synchronous Motors
Applications that involve load fluctuations and high impacts can
easily put a motor out of synchronization, so these are not suitable
applications. They have higher starting currents and rated currents
than standard motors and do not maintain stable speeds at low
speeds, please take these factors into consideration.
■ Single-Phase Motors
Single-phase motors are not suited to variable speed operation with
inverters. The harmonic current that flows to the capacitor in
capacitor-started motors can damage the capacitor. Motors that are
phase-split started or repulsion started not only do not provide
output torque at low speeds, their internal centrifugal force switches
also do not engage, so their starting coils sometimes burn. If inverter
operation is desired please use three-phase motors.
Operating Cautions
■ Operation
● To avoid damage to the inverter when a magnetic contactor (MC)
is installed on the primary side, please do not subject the MC to
repeated start/stop operations.
● When a malfunction occurs in the inverter, the protection
function engages to halt inverter output but does not suddenly
stop the motor itself. For this reason, please install the
mechanical stopping and holding mechanism necessary for
emergency stops.
● When the inverter's power supply is cut off, it takes time for the
capacitors to discharge. When carrying out inspections, wait at
least ten minutes after the power cuts off, then use a meter to
confirm that the voltage has decreased.
■ Wiring
● The inverter will be damaged if electric power is applied to the
inverter's output terminals U, V, and W. Before switching on the
power, please check the wiring and sequence very carefully.
● Terminals P (+), PR, P1, and N (–) are designed for use in
connecting dedicated optional equipment. Do not connect other
equipment to these terminals. Also, do not short frequency
setting power supply terminal 10 to common terminal 5.
■ Installation
● Please install the unit in a clean location, avoiding adverse
environments such as oil mist, lint, dust etc. or use it within a
sealed enclosure which keeps out floating particles. The
enclosure's cooling system and dimensions should allow the
inverter's ambient temperature to remain within the permissible
values (see page 9 for specifications).
● Since certain parts of the inverter can get extremely hot, do not
attach it to combustible material.
● The unit should be installed vertically.
■ Settings
● Control panel settings make it possible to set the inverter for high
speed operations up to 400Hz, so a mistake when setting can be
very dangerous. Use the maximum frequency setting function to
set an upper limit. (The default setting is a maximum frequency
of 60 Hz during external input signal operations. PU operation is
set for 120Hz.)
● Please do not set the regenerative brake duty function (Pr. 70)
except when the optional brake resistor is being used. Since this
function is used to protect against brake resistor overheating, do
not set it beyond the brake resistor's permissible duty.
● Setting the DC braking voltage and operation time at a higher
value than the default setting can cause motor overheating
(electronic thermal trip).
■ Power Requirements
● If the unit is installed close to a large-capacity power supply
transformer, or where switching of a phase advance capacitor
occurs, an excessive peak current may flow in the power input
circuit, damaging the inverter. In such cases, be sure to install an
optional FR-BEL or FR-BAL power supply coordinating reactor.
● If a surge voltage occurs in the power system, the surge energy

may flow into the inverter, causing the inverter to display E.OV1,

sure to install an optional FR-BEL or FR-BAL power supply
coordinating reactor.

read the manual before use.
Mitsubishi general-purpose inverters are not designed or
manufactured to be used in equipment or systems in situations
that can affect or endanger human life.
When considering this equipment for operation in special
applications such as machinery or systems used in passenger
transportation, medical, aerospace, atomic power, electric
power, or submarine repeating applications, please contact your
nearest Mitsubishi sales representative.
Although this product was manufactured under conditions of
strict quality control, you are strongly advised to install safety
devices to forestall serious accidents when it is used in facilities
where a breakdown in the product is likely to cause a serious
accident.
Please do not use for loads other than 3-phase induction motors.
● The motor's acceleration/deceleration time is determined by the
torque and load torque generated by the motor and by the
moment of inertia (GD2) of the load.
● Should the current limit function or stall prevention function
engage during acceleration/deceleration, the time sometimes
increases, so make the acceleration/deceleration time greater.
● To shorten the acceleration/deceleration time, make the torque
boost value larger, select general-purpose flux vector control or
increase inverter and motor capacity. (Too large a torque boost
value will activate the stall prevention function, actually
lengthening the acceleration time.) To shorten the deceleration
time, add the optional MRS or FR-ABR brake resistor (for 0.4K or
higher).
For Selecting Peripherals
■ Selecting and Installing No-Fuse Breakers
● Please install a no-fuse breaker (NFB) on the incoming side to
Selection Cautions
■ Selecting Inverter Capacity
● When running special motors or several motors in parallel off a
single inverter, select an inverter capacity so that the total motor
rated current (at 50Hz) is lower than the inverter's rated output
current.
● To make the motor quieter, set the PWM carrier frequency (Pr.72)
to 2kHz or higher and lower the output current as described in
the rating table on page 8 if you are using it in an ambient
environment of 40˚C or more. (Also change the setting for
electronic thermal O/L relay, Pr.9.) If the temperature is lower
than 40˚C, however, there is no need to lower the output current.
Note that when the PWM carrier frequency is raised, the motor
gets quieter but the inverter produces more noise and leakage
current. Select Soft-PWM control with (Pr. 240) to hold down the
increase in noise and make it less irritating.
■ Selecting a Brake Resistor
● Use the following table to select a brake resistor based on its
braking torque and permissible duty (%ED).
Capacity
Permissible duty 3%ED
Permissible duty 10%ED
■ Handling of Primary Magnetic Contactors
● When operating through the external terminals (using terminals
STF or STR), install a magnetic contactor (MC) on the primary
side to prevent accidents caused by restarts when the power
comes on after it has been off and ensure safety in maintenance
work. Do not use the MC to engage in frequent starts and stops.
(The life of the inverter input circuit is about 100,000 on-offs.)
● When operating the parameter unit, you cannot start operation
with an MC since the device does not restart automatically after
power is restored. It is generally not a good idea to stop with the
primary MC. The inverter's special regenerative brake will not
work, so the result will be a coasting stop.

■ Motor Starting Torque
● The starting and accelerating characteristics of motors driven by
41
protect the wiring on the inverter's primary side. The selection of
the NFB depends on the power factor on the inverter's power
supply side (changes in supply voltage, output frequency, or
load) (See page 32). In particular, since the operating
characteristics of fully electromagnetic NFBs are altered by
harmonic currents, it is necessary to select larger capacities.
(Refer to the documentation for the appropriate breakers for
more information.) Use Mitsubishi's anti-harmonic and anti-surge
Progressive Super Series as leakage breakers. (See page 32.)
● If you are installing no-fuse breakers on the secondary side of the
inverter, ripple currents will generate heat at the contacts, so
select a higher capacity.
inverters are constrained by the overload current rating of the
inverters used. Torque characteristic values are smaller than
when general commercial power supplies are used. When a
larger starting torque is necessary, select general-purpose flux
vector control (set motor capacity using Pr.80) or adjust the
torque boost value. When even these measures are inadequate,
choose an inverter with a capacity one rank higher or increase
the capacity of both the motor and the inverter.
the inverter and the motor and turn the inverter on and off during
operation. If the inverter is turned on during operation, a large
in-rush current flows into the inverter, and the inverter may stop
running due to the overcurrent. If an MC is used to switch to the
commercial power supply, the MC must be switched from ON to
OFF (inverter circuit) or from OFF to ON (commercial power
circuit) only after the inverter and the motor have stopped.
Cautions
■ Installing Thermal Relays
■ Wiring Thickness and Length
● The inverter is provided with a protection function that employs
● When the wiring distance between the inverter and the motor is
an electronic thermal relay to protect the motor from
overheating. When several motors or multi-polar motors are
operated using a single inverter, however, install a heat-activated
thermal relay (OCR) between the inverter and the motor(s). In
such cases, set the inverter's electronic thermal relay to 0 A and
the OCR setting to 1.0 times the current value on the motor's
rating plate for 50Hz or 1.1 times the value for 60Hz, taking interwire leakage current into account (see page 32 and 33).
long, the voltage across the main circuit cable drops, especially
for low frequency output. This causes the motor torque to drop.
Use thicker wires between the inverter and the motor so that the
voltage drop is 2% or less. (If wiring is longer than 20m, select
equipment as described on page 32.)
● When wiring is particularly long, the high-response current
limiting function may be engaged by the effects of charge current
caused by floating capacitance in the wiring, so keep the
maximum wiring length within the bounds suggested by the
table below. If you exceed these lengths, change the highresponse current limiting function parameters as described in the
manual.
■ Eliminating the Capacitor for Enhancing the
Power Factor (Phase-Advance Capacitor)
● The power factor-enhancing capacitor and surge breaker on the
inverter output side may be overheated and damaged by the
harmonic component of inverter output. In addition, an
overcurrent may flow in the inverter and set off the inverter's
overcurrent protection device. Therefore, do not install any
capacitor or surge breaker in the inverters output side. Use a
power-factor-enhancing AC reactor (see pages 36 and 37).
■ Secondary Instrumentation
● When wiring between inverter and motor is long, the effects of
leakage current between lines can generate heat in instruments
and current transformers. Select equipment that has a sufficient
margin in its current rating.
■ Radio Interference
● The input and output of the main inverter circuit contain higher
harmonic components that may interfere with communication
equipment (such as AM radios) and sensors that are being used
close to the inverter. You can reduce interference by attaching a
radio noise filter FR-BIF (for input side only), a line noise filter
FR-BSF01, or an SF type noise filter.

● When operating with general-purpose flux vector control, keep
the wiring length between inverter and motor to 30 m or less. (If
you need more than 30 m of distance, use off-line auto-tuning.)
● To connect the inverter to a parameter unit that is separated from
the inverter, use the special connecting cable, connector adapter,
and rear cover (optional). For remote operation using analog
signals, make sure the control line between the operation box or
operation signal and the inverter is no more than 30 m. Locate
wires away from strong electrical circuits (such as the main
circuit and the relay sequence circuit) to prevent induction from
other equipment.
● When setting frequency not with the parameter unit but with an
external potentiometer, use shielded or twisted wire, as shown
below, and connect shielded wire to Terminal 5, not to the
ground.
