Features
1. The Ability to Maximize Drive Performance
■ Advanced Flux Vector Control
Example of motor temperature/speed variation characteristics
(SFJR 4P 3.7kW motor). (Repeated operations at 90% usage rate,
on-line auto tuning selected)
New levels in drive performance have been achieved thanks to the
use of advanced flux vector control, an original technology
developed by Mitsubishi.
320
The units feature a RISC processor which is used for on-line auto
tuning, turning the motor quickly when starting. This allows it to
perform high-precision operations that are unaffected by motor
temperature, as well as stable high-torque operation from ultra
low speeds.
Speed control range: 1:120 (0.5~60Hz, driving mode)
Using the auto tuning function, high precision operation is
possible with motors from all over the world.

Features
■ Smart Driver
Uneven rotation at low speeds has been greatly improved by the
use of a smart driver (a newly developed ASIC) which directly
monitors and controls the main circuit's status.
• Uneven rotation: less than half that of a conventional Mitsubishi
inverter at 1 Hz

■ High-response Current Limit
■ Expandability
Further improving the responsiveness of current detection has
reduced the occurrence of trips arising from overcurrent.
This makes it possible to deal more effectively with the momentary
large currents that occur when starting a reverse coasting motor or
when switching an MC ON and OFF on the inverter output.
Various I/Os are available, including pulse train, analog signals,
digital signals, and network connections.
• Up to three option cards can be mounted internally.
• Direct communications with a PLC is possible, e.g. Control &
Communication Link (CC-Link).
Accommodates PLC X/Y instructions for easy programming.
■ New Functions
The addition of a number of new functions has made it possible to
handle various applications.
Some examples are:
• Power failure deceleration stop function
→ Rotary cutters, etc.
• PID control → Air-conditioning, etc.
• Brake sequence function → Conveyors, etc.
• Commercial power supply inverter switch-over sequence
function → Pumps, etc.

2. Achieves New Levels of User-friendliness
■ Simple Operation
FR-DU04 control panel
● The simple FR-DU04 control panel is provided as standard on all
models.
An optional extension cable can be used with the control panel.
Operational and alarm signals can also be shown with this unit.
● The FR-PU04 LCD parameter unit with long-life backlight display
is available as an option.
The unit features Mitsubishi's original direct input method which
uses the ten-key pad. Eight different languages are available on
one unit.
● The parameter user group function is provided as standard.
This function facilitates control of parameters by making it
possible to select, read and write only those parameters that are
required.
● Communications is a standard feature.
The control panel can be disconnected to allow the unit to be
controlled by a personal computer via an RS-485 interface.
Note: A converter is necessary if an RS-232C interface is to be used.
FR-PU04 parameter unit (option)
■ Easy Maintenance
● The life of the cooling fan has been extended by the use of
ON/OFF control, and replacement is easier.
Simple to install/remove control terminals
● Simple installation and removal of the control terminal block
makes maintenance easier.
● Parameters can be preserved by the control panel which is fitted
as standard.
When an inverter is replaced, parameters can be set up simply by
writing previously stored parameters from the control panel.
Note: It is necessary to batch-read the parameters at the control panel
beforehand.

3. Environmentally Friendly
■ Soft-PWM Control
In addition to the conventional low-noise mode, Mitsubishi has developed its own original Soft-PWM control method which suppresses the
increase in acoustic noise and limits RFI noise to minimum levels similar to those of the Mitsubishi FR-Z Series inverter.
Note: The default setting is Soft-PWM control ON.

Since the frequency components are dispersed, the motor generates little metallic
noise and does not sound unpleasant.
Since the frequency components are concentrated, the motor generates a grating
metallic noise.
■ Compatible with Harmonic Limits
■ EMC Filter Available
● A compact direct current reactor (DCR) can be connected to units
of all capacities.
● It is also possible to connect a high-power factor regenerative
converter (FR-HC) that conforms to Japanese harmonic
guidelines (conversion coefficient: K5=0).
● Using the optional EMC filter makes it easy to comply with
European EMC Directives.

Notes: 1. "Applicable motor capacity" refers to the maximum applicable capacity when using a 4-pole standard Mitsubishi motor.
2. The rated output capacity is 220V for the 200V class, and 440V for the 400V class.
3. The percentage given for the overload current rating indicates the ratio with respect to the inverter's rated output current. In the case of repeated use, it is essential
to wait until the inverter and the motor have cooled to below the temperature for 100% load.
4. The maximum output voltage may not exceed the power supply voltage, and can be set at any value below the power supply voltage.
5. Indicates the average torque for decelerating to a stop from 60Hz. Changes according to motor loss.
6. Power capacity differs according to the power supply impedance value (including the input reactor or wire values).

■ Making the housing plate more compact
Housing plate
When the inverter is being used inside a housing plate, the heat
generated inside the plate can be greatly reduced by projecting the
inverter's heat radiating fin outside of the plate. This mounting method is
recommended when trying to reduce the size of a completely sealed
housing plate.
Notes
1. When mounting, use mounting attachment FR-A5CN (sold separately)
(for models 1.5K~55K).
2. The fin height is greater than the height of the FR-A200 series.

Copying Parameters
Parameter settings can be copied to another inverter (excluding non-FR-A500 series inverters) by using
the FR-DU04 operation panel or the FR-PU04 parameter unit. First, all of the parameters on the source
inverter are read, the operation panel is connected to the target inverter, and all of the parameters are
then written to the inverter.

● Thanks to the wide-range speed control, high-speed operation is
possible without any decline in stopping precision.
● A brake unit is not required because a power regeneration
function is provided.
● Since elevation and travel are performed simultaneously, the
high-power factor converter should be selected according to the
capacity of the elevation motor plus the capacity of the travel
motor.
● The mechanical brake power supply is connected to the power
supply of the high-power factor converter.
● The mechanical brakes can be applied with optimal timing using
the brake sequence function.
● The large starting torque allows powerful performance in lifting
operations.
● Since advanced flux vector control offers high operational
precision, it is possible to alter the speed of each roll slightly
during draw control operations.
● Driving the rear stage rolls at slightly higher speeds than the front
stage rolls allowing stable operation in which tension is
maintained at a rate that matches the elongation rate of the
material.
● When the on-line auto tuning function is selected, the motor
constants are automatically tuned each time the motor starts,
eliminating speed variations caused by temperature fluctuations
and providing stable control.

● Because of the PID control function built into the inverter,
constant temperature control operation is possible.
● MCl-MC3 operation timing can be controlled with optimum
precision using the inverter's built-in commercial power supply
switchover sequence function. The external switchover
sequence circuit is also simplified.
● An electromechanical interlock that prevents MC2 and MC3 from
being turned ON simultaneously is required.
● The inverter controls temperature constantly during operation,
creating a pleasant environment and conserving energy.
23
● The frequencies for the two inverters used for extrusion and pulloff can be set with one frequency potentiometer. The ratio
between the operational frequencies of the two inverters is
adjusted for the bias and gain (Pr. 902 and 903) of the input
frequency signal.
● Advanced flux vector control (on-line auto tuning) makes it
possible to carry out operations with minimal speed fluctuation.
As a result, extrusion pressure can be accurately controlled
according to the differences in the materials being extruded.
● Using a PLG on the wind-up motor allows even more precise
control of operations.
Protective Functions
Except for the motor's electronic thermal relay, the following functions are provided for the protection of the inverter itself, but they may
also function when the inverter breaks down.
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 cut-off
Regenerative overvoltage
cut-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 thermal relay 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.
E.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
cut-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.)
E.THT
●
Instantaneous power failure
protection
When the power fails for more than 15ms and is restored within approximately 100ms, the instantaneous power failure
protection function activates to prevent erroneous operation of the control circuit, and halts inverter output. At this time,
error warning output contacts open (between terminals A and C) and close (between terminals B and C) (Note 4). If
the power failure continues for 100ms or more, the error warning output does not activate, and if the start signal is ON
when power is restored, the inverter restarts. (If the instantaneous power failure lasts for less than 15msec, the control
circuit functions normally.)
E.IPF
●
Undervoltage protection
(1) If the inverter's supply voltage drops, the control circuit can no longer fulfill its normal functions. Moreover, the
motor suffers from insufficient torque and overheating. For this reason, inverter output halts when the supply
voltage falls to 150V or below (300V or below in the case of 400 V class units).
(2) The undervoltage protection function operates if there is no short bar between P and P1.
E.UVT
●
Fin overheat
If the cooling fin overheats, the fin overheat sensor activates and halts inverter output.
E.FIN
●
Fan trouble
In the case of inverters with built-in cooling fans, "FN" is displayed at the control panel if the cooling fan stops operation
because of trouble, or operates differently from the setting for Pr. 244 (Cooling fan operation selection). Inverter output
does not halt.
FN
Brake resistor overheating
protection
Inverters with a capacity of 7.5K or less are equipped with a built-in brake resistor. When the regenerative energy from
the motor exceeds the prescribed value, brake circuit operations halt temporarily to protect the brake resistor from
overheating. (Performing braking operations in this state causes a regenerative overvoltage cut-off.) After the time
required to cool the brake resistor has passed, brake circuit operations restart.
---
Brake transistor error detection
Inverter output halts when the brake transistor is damaged or other faults occur in the brake circuit. In such cases, it is
necessary to shut off the inverter's power supply immediately.
E.BE
●
Output side ground fault
overcurrent protection
Inverter output halts when a ground fault occurs on the inverter's output side (load side) and a ground fault overcurrent
is generated.
E.GF
●
External thermal relay
operation (Note 1)
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.
E.OHT
●
Option error
(1) When a dedicated built-in type option is installed within the inverter, inverter output halts if there is a setting error or
the connection is faulty.
(2) When a high-power factor converter connection is set, the display indicates that an AC power supply is connected to
R, S, T.
E.OPT
●
Parameter error
Generated when an error occurs in a stored parameter (e.g. E2ROM breakdown).
E.PE
●
PU disconnected
Inverter output halts when communication between the main unit and the PU are interrupted by disconnection of the
PU, etc., when Pr. 75 is set to 2,3, 16, 17.
E.PUE
●
No. of retries exceeded
When operations cannot be restarted normally within the set number of retries, inverter output is halted.
E.RET
●
Output phase loss detection
Detects when the inverter looses an output phase (U, V or W).
E.LF
●
CPU error
If the built-in CPU does not complete operations within the prescribed time, it self-diagnoses a fault and halts inverter
output.
E.CPU
●
During
acceleration
When a current of 150% (Note 2) 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.
OL
At constant
speed
When a current of 150% (Note 2) or more of the inverter's rated current flows in the motor, the frequency is lowered
until the load current declines, preventing the inverter from executing an over-current shut-off. The frequency is
restored to the set level once the current falls below 150% of the rated value.
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 2) 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.

short circuit
When the 24VDC power output from the PC terminal is short circuited, power output is shut off. At such times, all
external contact inputs are switched OFF. Resetting cannot be performed by an RES signal input. To reset, either use
the control panel or shut off the power, then turn it on again.
E.P24
Operating panel power supply
short circuit
When the control panel power supply (P5S of the PU connector) is short circuited, power output is shut off. At such
times, it is not possible to use the control panel (parameter unit) or perform RS-485 communications from the PU
connector. To reset, either input an RES signal or shut off the power, then turn it on again.
E.CTE
Brake sequence error
In the case where a sequence error occurs when using the brake sequence functions (Pr. 278~Pr. 285), inverter output
is halted. Please consult the manual for details about errors.

E.MB1~MB7
Notes:
1. External thermal relay operations are only performed when Pr. 180~Pr. 186 (input terminal function selection) is set to OH.
2. Indicated when the stall prevention operation current level is set to 150% (default setting). When this value is altered, stall prevention is performed at the altered set value.
3. Major faults: The protective function activates, inverter output is shut off, and an error out is executed. Minor faults: Output is not shut off even when the protective function
activates. It is possible to output minor fault signals by setting parameters.
4. In the case where Pr. 190~Pr. 196 (output terminal function selection) are set to the default values.
24
Protective Functions
● Resetting Methods
When a protective function is activated, it halts inverter output (the
motor coasts to a halt). It is held in this state and will not restart
unless it is reset. To reset the inverter, three methods are available:
- shut off the power, then turn it on again;
- switch the reset (RES) signal ON for at least 0.1 second, then OFF;
- press the RESET key on the control panel or parameter unit. (Use
the parameter unit’s help function)
If the RES signal is ON continuously, the control panel indicates
"Err" while the parameter unit indicates that it is in the process of
resetting.
Notes:
1. Displays
When the protective circuit is activated, the LED display on the control panel
automatically changes according to the indications in the above table. In the
case of the parameter unit, the unit's liquid crystal display gives a more detailed
explanation of the fault.
2. Holding the error output signal
When protective functions operate, if the electromagnetic contactor installed on
the inverter's power supply side is switched OFF, the inverter's control source
disappears and it becomes impossible to hold the error output signal. If it is
necessary to hold the signal, make the error output a sequence that is held
externally.
If the control circuit is provided with a separate power supply as described
below, it is possible to hold the error signal and error display. Details of the
fault are stored even if the power supply is shut off, and can be confirmed at the
control panel (parameter unit).
■ Connecting the control circuit to a separate power supply
● In the case of FR-A520-0.4K~3.7K/FR-A540-0.4K~3.7K
Remove the short bar between terminals R-R1 and S-S1, and
connect the control source to terminals R1, S1.
● In the case of FR-A520-5.5K~55K/FR-A540-5.5K~55K
As shown in the diagram, remove the short bars from the two-tier
terminal block (see inverter manual for further details), and connect
the control source to the upper-tier terminal.
Note: Connecting the control source to the lower-tier terminal will damage the
inverter.

Notes:
1. The control source (R1, S1) does not need to be phase sequenced with the main power supply (R, S, T). However, the phase sequence must be matched when the optional
FR-HC high-power factor converter is used.
2. Even if the main power supply is OFF, the error output will not function.
3. The inverter can be reset by turning the main power supply OFF, the ON again.
4. Do not turn the control source OFF when the main power supply is ON.
5. When using the FR-BIF radio noise filter (sold separately), connect it to the primary side of the MC. If it is connected to the secondary side, the insufficient voltage alarm
(E.UVT) will be triggered when the MC is turned off.

Selecting Peripherals and Options
Name (Model)
Power facility capacity
Functions & Applications, etc.
Please select a power supply that is larger than the kVA values stated
in the "Power facility capacity" column in the Ratings table (p.8).
However, in the case where the value exceeds 1000kVA and the wiring
length is 10m or less, install an FR-BEL DC reactor (or AC reactor) to
balance the power supply. It should also be installed to prevent
erroneous operation of the inverter in the case where surge voltages
occur in the power supply line because thyristor converters, vacuum
contactors, etc., exist on the same power supply system. In addition, it
is effective in improving the inverter's power factor. Finally, it should
also be installed when the imbalance in the supply voltage is 3% or
more.

A large inrush current flows when the inverter's power is turned on, it is
necessary to be careful when selecting a no-fuse breaker. When
selecting an earth leakage breaker, please select a model such as
Mitsubishi's New Super NV which has been designed to cope with the
high frequency components generated by the inverter, and can cope
with high frequencies and surges.

Specifications, configurations, etc.
• By using this attachment, the cooling fin, which is the inverter's heatgenerating component, can be extended to the back of the housing plate.
This makes it possible to radiate the inverter's heat to the back of the
housing plate, allowing the control panel to be made more compact.
• Use of this attachment increases the mounting space by the size of the
attachment. Therefore, when using this attachment, refer to the
dimensions (page 12) that include the attachment.
• Refer to page 12 for the dimensions of the panel cut.
• The inverter can be converted to IP40 specification by mounting this
attachment on the inverter’s top/bottom or left/right slits.
• This attachment is suited for wall mounting.
(The IP40 [JEM1030]: The attachment is constructed so that wires larger
than 1 mm in diameter or drive belts thicker than 1 mm do not project into
the inverter.)

Notes:
1. When using the FR-ABR brake resistor, remove the short
bar between terminals PR and PX. Leaving the short bar
in place will cause the built-in brake resister to overheat.
(There is no need to remove the built-in brake resistor.)
2. Regenerative brake duty should be set at levels below the
permissible brake duty levels stated in the table.
3. Since the temperature of the brake resistor may exceed
300C°, depending on how frequently it operates, please
take care with installation and heat dissipation.
4. MYS type resistors may also be used, but care should be
taken with permissible brake duty.

Measures to deal with leakage current
Please take the following steps to prevent erroneous operation of peripherals and electric shocks caused by leakage current:
1. Ground the noise filter before connecting to the power supply. In this case, please confirm that it is properly grounded to earth via the panel's ground.
2. Please note, the noise filter's leakage current when selecting earth leakage breakers or earth leakage relays. Also, in cases where earth leakage
breakers or earth leakage relays cannot be used because the leakage current of a large-capacity noise filter is too large, ensure that the grounding
measures referred to in 1. are properly taken.

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.

Points to Note when Using and Selecting Units
■ For Maximum Safety
• In order to use the equipment properly and safely, please be sure
to read the manual before use.
• This product was not designed or manufactured as equipment or
a system to be used in situations that can affect or endanger
human life.
• When considering this equipment for operations in special
machinery or systems used in passenger-moving applications,
medical applications, aerospace applications, atomic power
applications, electric power applications, or submarine repeating
applications, please contact Mitsubishi Electric Corporation's
sales department.
• Although this product was manufactured under conditions of
strict quality control, you are strongly advised to install safety
devices when it is used in facilities where a breakdown in the
product is likely to cause a serious accident or loss.
• Please do not use loads other than 3-phase induction motors.
Operation
• To avoid damage to the inverter when an electromagnetic
contactor (MC) is installed on the primary side, please do not
subject the MC to repeated start/stop operations.
• When a fault occurs in the inverter, the protective function
activates and halts inverter output, but does not suddenly stop the
motor itself. For this reason, please install the mechanical
stopping and holding mechanisms necessary as mechanical
equipment for emergency stops.
• Even if the inverter's power supply is cut off, it takes time for the
capacitor to discharge. When carrying out inspections, wait for at
least 10 minutes after the power supply has been cut off, then use
a tester, etc., to confirm the voltage.
Wiring
• The inverter will be damaged if electric power is applied to the
inverter's output terminals (U, V, W). Before switching on the
power, please check wiring and sequence very carefully to
ensure there are no wiring connection errors.
• Terminals P, P1, PR, PX and N are designed for use in connecting
specially designed, dedicated options.
Do not connect
equipment other than dedicated options to these terminals. Also,
please do not create a short circuit between power terminal 10,
which is used for setting frequency, and common terminal 5.
Installation
• Please install the unit in a clean location, avoiding adverse
environments such as oil mist, fluff, dust, etc., or use it within a
sealed enclosure which will not allow the entry of floating
particles. In the latter case, please ensure that the cooling system
and dimensions allow the inverter's ambient temperature to
remain within the permissible values (see page 9 for specification
values). The enclosure can be made more compact if the FRA5CN option is used for isolating the inverter's heat generating
parts outside the enclosure is used.
• Since certain parts of the inverter can get extremely hot, do not
attach it to combustible material.
• The unit should be attached to the wall, vertically
Power Supply
• In cases where the unit is installed directly below a large-capacity
power supply (1000 kVA or over, length of wiring 10 meters or
less), 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 factor improvement reactor.

• If a surge voltage occurs in the power system, the surge energy
may flow into the inverter, causing the inverter to execute an
over-voltage alarm stop. In such cases, be sure to install an
optional FR-BEL or FR-BAL power factor improvement reactor.
Settings
• Using the control panel or the parameter unit for setting makes it
possible to set the inverter for high-speed operations up to
400Hz, so a mistake when setting can be very dangerous. Use the
upper frequency setting function to set an upper limit. (The
default setting is a maximum frequency of 60Hz during external
input signal operations. PU operations are 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 overheating of the brake
resistor, do not set it at a level that exceeds 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 relay trip).
Points to Note
Selecting Inverter Capacity
• In the cases where special motors or several motors are operated
in parallel using a single inverter, select an inverter whose
capacity is such that the total rated current of the motors is equal
to or less than the inverter's rated output current.
Motor Starting Torque
• The starting and accelerating characteristics of motors driven by
inverters are constrained by the overload current rating of the
inverters used in combination. Torque characteristic values are
smaller than when general commercial power supplies are used.
When a large driving torque is necessary and even advanced flux
vector control is inadequate, please choose an inverter with a
capacity that is one rank higher, or increase the capacity of both
the motor and the inverter.
Acceleration/Deceleration Time
• 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.
• In the case where the current limit function or stall prevention
function activates during acceleration/deceleration, the time
sometimes increases, so please make the acceleration/
deceleration time greater.
• When you wish to shorten the acceleration/deceleration time,
make the torque boost value larger or select advanced flux vector
control. (Making the torque boost value too large may activate
the stall prevention function, otherwise, try lengthening the
acceleration time.) If this is still not enough, increase the capacity
of both the inverter and the motor. To shorten the deceleration
time, it is necessary to add the optional FR-ABR brake resistor for
frequent braking operations (for capacities of 7.5K and below), or
the optional FR-BU brake unit or the optional FR-RC power
regenerating converter, etc., necessary for absorbing braking
energy

Points to Note when Selecting Peripherals
■ Selecting and Installing No-fuse Breakers
Please install a no-fuse breaker (NFB) on the incoming side to
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, load); In
particular, since the operating characteristics of fully
electromagnetic type NFBs change according to high frequency
current, it is necessary to select larger capacities. (Use the materials
on the appropriate breakers for confirmation.) Also, for leakage
breakers, please use models that have been designed to cope with
high frequencies and surges, such as Mitsubishi's New Super NV.
■ Handling Primary Side Electromagnetic
Contactors
Inverters may be used without electromagnetic contactors (MC) on
the power supply side. In the case of operations using external
terminals (using terminals STF or STR), even if a primary-side MC is
installed to prevent accidents caused by natural restarts when
power is restored following instantaneous power failures, etc., or to
ensure safety during maintenance operations, please do not use the
MC to execute frequent start/stop operations (the switching life of
an inverter input circuit is approximately 100,000 operations). In
PU operation mode, inverters do not restart automatically after
power is restored, so they cannot be restarted by the MC. It is
possible to halt operations using a primary side MC, but the
inverter's special regenerative brake does not function and the
motor coasts to a stop.
There is a danger that the high frequency components of the
inverter's output will cause overheating and damage any power
factor improvement capacitor and surge killer installed on the
inverter's output side. Furthermore, neither capacitor nor surge
killers should be inserted because current flows in the inverter
causing the overcurrent protection function to activate. Use the
power factor improvement DC reactor (page 31) for power
improvement.
■ Noise
During quiet operation, electromagnetic noise tends to increase, so
countermeasures should be taken. Depending on how the inverter
is installed, noise may have effects even when the carrier frequency
is lowered.
Countermeasures
• The noise level can be reduced by lowering the carrier frequency.
• An FR-BIF(H) radio noise filter is effective at countering AM radio
noise.
• An FR-BSF01 or FR-BLF line noise filter is effective at preventing
sensor malfunctions.
• Separate wires by at least 30cm (at the very least 10cm) from
inductive noise from inverter power wires and use twisted pair
shielded cable for signal lines.
■ Leakage Current
Please note carefully that when an electromagnetic contactor is
installed between the inverter and the motor, and an OFF/ON
procedure is performed during operations, a large inrush current
occurs and may affect the motor. When an MC is installed for
switching to commercial power supplies, etc., we recommend that
you use commercial power supply switchover functions Pr. 135 ~
Pr. 139.
Electrostatic capacitance occurs between inverter I/O wiring and
other wiring, the ground and motor wiring. Current can leak
through any of these. Its value can be affected by the carrier
frequency etc., so in low noise operation leakage current increases
and leakage breakers and relays can operate at unwanted times.
Adopt the following counter measure to prevent this.
Countermeasure
• Lower inverter carrier frequency Pr.72. Motor noise, however, will
increase.–Therefore, it is recommend that you use Soft-PWM
control Pr. 240.
■ Installing Thermal Relays
■ Power Supply Harmonics
The inverter is provided with a protection function that employs an
electronic thermal relay to protect the motor from overheating.
However, in cases where several motors or multi-polar motors are
operated using a single inverter, please install a heat-activated type
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 1.1 times the current value on the motor's rating plate
taking inter-wire leakage current into account.
A harmonic is defined as having a frequency that is an integer
multiple of its basic frequency. Normally, frequencies up to 40 or 50
times (to several kHz) are defined as harmonics, while higher
harmonics are treated as noise. The table below clarifies causes and
responses to noise and harmonics.
■ Handling Secondary Side Electromagnetic
Contactors
■ Secondary-side Measuring Instruments
When the wiring between the inverter and the motor is long, the
effects of inter-wire leakage current, especially with small-capacity,
400V class units, may cause heating in instruments or Current
Transformers. For this reason, please select instruments that have
an adequate current rating.
When the inverter's output voltage and output current are measured
and displayed, we recommend that you make use of the inverter's
AM-5 terminal output function.

Points to Note when Selecting Peripherals
■ Wiring Thickness and Distances
When the wiring distance between the inverter and the motor is
long, use a thick wire that will keep the drop in voltage in the main
circuit cable to 2% or less, especially during low frequency output.
In cases of long distance cabling, the effects of charging current
arising from floating capacity in the wiring may cause the
overcurrent protection function to activate erroneously, so the
maximum length of the wiring should not exceed 500 meters.
When advanced flux vector control is selected for operations, the
wiring between the inverter and the motor should be a maximum of
30 meters long. (When the length of the wiring exceeds 30 meters,
perform off-line auto-tuning.)
Please use the recommended connecting cable when installing the
control panel (parameter unit) separately from the main body.
When performing remote operations using analog signals, the
control wire between the control signal and the inverter should be
a maximum of 30 meters long, and should be isolated from power
circuits (main circuit and relay sequence circuits) so as not to be
affected by induction from other equipment.
When the frequency is set using an external volume control
(potentiometer) rather than the control panel (parameter unit),
please use shielded or twisted wire as shown in the drawing, and
connect the shield to terminal 5, not to earth.
