SAFETY INSTRUCTIONS
1. Electric Shock Prevention
WARNING
! While power is on or when the inverter is running, do not open the front cover.
You may get an electric shock.
! Do not run the inverter with the front cover removed. Otherwise, you may access
the exposed high-voltage terminals or the charging part of the circuitry and get an
electric shock.
! 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 power off, wait for more than 10
minutes, and check for residual voltage with a meter (refer to chapter 2 for further
details) etc.
! Earth the inverter.
! Any person who is involved in the wiring or inspection of this equipment should be
fully competent to do the work.
! Always install the inverter before wiring. Otherwise, you may get an electric shock
or be injured.
! Operate the switches and potentiometers with dry hands to prevent an electric
shock.
! Do not subject the cables to scratches, excessive stress, heavy loads or pinching.
Otherwise, you may get an electric shock.
! Do not change the cooling fan while power is on.
It is dangerous to change the cooling fan while power is on.
! While power is on, do not move the station number and baudrate setting switches.
Doing so can cause an electric shock.
2. Fire Prevention
CAUTION
! Mount the inverter and brake resistor on an incombustible surface. Installing the
inverter directly on or near a combustible surface could lead to a fire.
! If the inverter has become faulty, switch off the inverter power. A continuous flow
of large current could cause a fire.
! When a brake resistor is used, use an alarm signal to switch power off.
Otherwise, the brake resistor will overheat abnormally due a brake transistor or
other fault, resulting in a fire.
! Do not connect a resistor directly to the DC terminals P (+), N (−). This could
cause a fire.

(2) Wiring
CAUTION
! Do not fit capacitive equipment such as a power factor correction capacitor,
radio noise filter or surge suppressor to the output of the inverter.
! 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
! Check all parameters, and ensure that the machine will not be damaged by a
sudden start-up.
(4) Operation
WARNING
! When you have chosen the retry function, stay away from the equipment as it
will restart suddenly after an alarm stop.
! 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.
A-4
CAUTION
! The electronic overcurrent protection does not guarantee protection of the motor
from overheating.
! Do not use a magnetic contactor on the inverter input for frequent
starting/stopping of the inverter.
! 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 harmonics from the
inverter may heat/damage the power capacitor and generator.
! When parameter clear or all clear is performed, each parameter returns to the
factory setting. Re-set the required parameters before starting operation.
! 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.

2.1 Installation
2.1.1 Instructions for installation
When mounting any of the FR-E520-0.1KN to 0.75KN, remove the accessory cover,
front cover and wiring cover.
1) Handle the unit carefully.
The inverter uses plastic parts. Handle it gently to protect it from damage.
Also, hold the unit with even strength and do not apply too much strength to the front
cover alone.
2) Install the inverter in a place where it is not affected by vibration easily (5.9m/s2
maximum.).
Note the vibration of a cart, press, etc.
3) Note on ambient temperature.
The inverter life is under great influence of ambient temperature. In the place of
installation, the ambient temperature must be within the permissible range -10°C to
+50°C. Check that the ambient temperature is within the permissible range in the
positions shown in Fig. 3).
4) Install the inverter on a non-combustible surface.
The inverter will be very hot (maximum about 150°C). Install it on a non-combustible
surface (e.g. metal). Also leave sufficient clearances around the inverter.
5) Avoid high temperatures and high humidity.
Avoid direct sunlight and places of high temperature and high humidity.
6) Avoid places where the inverter is exposed to oil mist, flammable gases, fluff, dust,
dirt etc.
Install the inverter in a clean place or inside a "totally enclosed" panel which does
not accept any suspended matter.

INSTALLATION AND WIRING
7) Note the cooling method when the inverter is installed in an enclosure.
When two or more inverters are installed or a ventilation fan is mounted in an
enclosure, the inverters and ventilation fan must be installed in proper positions with
extreme care taken to keep the ambient temperatures of the inverters with the
permissible values. If they are installed in improper positions, the ambient
temperatures of the inverters will rise and ventilation effect will be reduced.
8) Install the inverter securely in the vertical direction with screws or bolts.

INSTALLATION AND WIRING
2.2.2 Wiring of the Main Circuit
(1) Wiring instructions
1) It is recommended to use insulation-sleeved solderless terminals for power supply
and motor wiring.
2) Power must not be applied to the output terminals (U, V, W) of the inverter.
Otherwise the inverter will be damaged.
3) After wiring, wire off-cuts must not be left in the inverter.
Wire off-cuts can cause an alarm, failure or malfunction. Always keep the inverter
clean.
When drilling mounting holes in a control box or the like, be careful so that chips and
others do not enter the inverter.
4) Use thick cables to make the voltage drop 2% or less.
If the wiring distance is long between the inverter and motor, a main circuit cable
voltage drop will cause the motor torque to decrease, especially at the output of a
low frequency. (A selection example for the wiring length of 20m is shown on page
18.)
5) For long distance wiring, the overcurrent protection may be activated improperly or
the devices connected to the output side may misoperate or become faulty under
the influence of a charging current due to the stray capacitance of the wiring.
Therefore, the maximum overall wiring length should be as indicated in the following
table. If the wiring length exceeds the value, it is recommended to set "1" in Pr. 156
to make the fast-response current limit function invalid. (When two or more motors
are connected to the inverter, the total wiring length should be within the indicated
value.)

INSTALLATION AND WIRING
6) Connect only the recommended optional brake resistor between the terminals
P-PR (+-PR). Keep terminals P-PR (+-PR) of 0.1K or 0.2K open.
These terminals must not be shorted.
0.1K and 0.2K do not accept the brake resistor. Keep terminals P-PR (+-PR) open.
Also, never short these terminals.
7) Electromagnetic wave interference
The input/output (main circuit) of the inverter includes harmonic components, which
may interfere with the communication devices (such as AM radios) used near the
inverter. In this case, install the FR-BIF optional radio noise filter (for use in the input
side only) or FR-BSF01 or FR-BLF line noise filter to minimize interference.
8) Do not install a power capacitor, surge suppressor or radio noise filter (FR-BIF
option) in the output side of the inverter.
This will cause the inverter to trip or the capacitor and surge suppressor to be
damaged. If any of the above devices are installed, immediately remove them.
(When using the FR-BIF radio noise filter with a single-phase power supply, connect
it to the input side of the inverter after isolating the T phase securely.)
9) When rewiring after operation, make sure that the POWER lamp has gone off, and
when more than 10 minutes has elapsed after power-off, check with a meter etc.
that the voltage is zero. After that, start rewiring work. For some time after power-off,
there is a dangerous voltage in the capacitor.
Notes on Grounding
" Leakage currents flow in the inverter. To prevent an electric shock, the inverter
and motor must be grounded.
" Use the dedicated ground terminal to ground the inverter. (Do not use the screw
in the case, chassis, etc.)
" The ground cable should be as thick as possible. Its gauge should be equal to or
larger than those indicated in the following table. The grounding point should be
as near as possible to the inverter to minimize the ground cable length.

INSTALLATION AND WIRING
2.2.3 Wiring of the control circuit
(1) Wiring instructions
1) Terminals SD are common terminals for I/O signals. These common terminals must
not be earthed to the ground.
2) Use shielded or twisted cables for connection to the control circuit terminals and run
them away from the main and power circuits (including the 200V relay sequence
circuit).
3) The frequency input signals to the control circuit are micro currents. When contacts
are required, use two or more parallel micro signal contacts or a twin contact to
prevent a contact fault.
4) It is recommended to use the cables of 0.3mm2 to 0.75mm2 gauge for connection to
the control circuit terminals.
5) When bar terminals and solid wires are used for wiring, their diameters should be
0.9mm maximum If they are larger, the screw threads may be damaged during
tightening.
(2) Terminal block layout
In the control circuit of the inverter, the terminals are arranged as shown below:

(3) Wiring method
1) For wiring the control circuit, use cables after stripping their sheaths.
Refer to the gauge printed on the inverter and strip the sheaths to the following
dimensions. If the sheath is stripped too much, its cable may be shorted with the
adjoining cable. If the sheath is stripped too little, the cable may come off.
7mm±1mm
2) When using bar terminals and solid wires for wiring, their diameters should be
0.9mm maximum. If they are larger, the threads may be damaged during tightening.
3) Loosen the terminal screw and insert the cable into the terminal.
4) Tighten the screw to the specified torque.
Undertightening can cause cable disconnection or misoperation. Overtightening can
cause damage to the screw or unit, leading to short circuit or misoperation.
Tightening torque: 0.25 N⋅m to 0.49 N⋅m
* Use a size 0 screwdriver.
Note : When routing the stripped cables, twist them so that they do not become loose.
In addition, do not solder it.
(4) Control logic changing
The input signal logic is factory-set to the sink mode.
To change the control logic, the position of the connector beside the control circuit
terminal block must be changed.
1) Using tweezers etc. to remove the connector in the sink logic position and fit it in the
source logic position.
Do this position changing before switching power on.
21
INSTALLATION AND WIRING
Note: 1. Make sure that the front cover has been installed securely.
2. The front cover has a capacity plate and the inverter a rating plate on it.
Since these plates have the same serial numbers, always reinstall the
removed cover to the inverter from where it was removed.
3. Always install the sink-source logic changing connector in either of the
positions. If two connectors are installed in these positions at the same time,
the inverter may be damaged.

2.2.7 Design information
1) Provide electrical and mechanical interlocks for MC1 and MC2 which are used for
commercial power supply-inverter switch-over.
When there is a commercial power supply-inverter switch-over circuit as shown
below, the inverter will be damaged by leakage current from the power supply due to
arcs generated at the time of switch-over or chattering caused by a sequence error.
2) If the machine must not be restarted when power is restored after a power failure,
provide a magnetic contactor in the inverter's primary circuit 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.
3) Since the input signals to the control circuit are on a low level, use two or more
parallel micro signal contacts or a twin contact for contact inputs to prevent a contact
fault.
4) Do not apply a voltage to the contact input terminals of the control circuit.
5) Always apply a voltage to the alarm output signal terminals (A, B, C) via a relay coil,
lamp, etc.
6) Make sure that the specifications and rating match the system requirements.

2.3.2 Japanese harmonic suppression guideline
Harmonic currents flow from the inverter to a power receiving point via a power
transformer. The harmonic suppression guideline was established to protect other
consumers from these outgoing harmonic currents.
1) "Harmonic suppression guideline for household appliances and general-purpose
products"
This guideline was issued by Ministry of Economy, Trade and Industry (formerly
Ministry of International Trade and Industry) in September, 1994 and applies to 3phase 200V class inverters of 3.7kW or less. By installing the FR-BEL or FR-BAL
power factor improving reactor, inverters comply with the "harmonic suppression
techniques for transistorized inverters (input current 20A or less)" established by the
Japan Electrical Manufacturers' Association. Therefore install the optional reactor for
the 3-phase 200V class, 3.7kW or less inverter.
2) "Harmonic suppression guideline for specific consumers"
This guideline sets forth the maximum values of harmonic currents outgoing from a
high-voltage or specially high-voltage consumer who will install, add or renew
harmonic generating equipment. If any of the maximum values is exceeded, this
guideline requires that consumer to take certain suppression measures.

1) Calculation of equivalent capacity (P0) of harmonic generating equipment
The "equivalent capacity" is the capacity of a 6-pulse converter converted from the
capacity of consumer's harmonic generating equipment and is calculated with the
following equation. If the sum of equivalent capacities is higher than the limit in
Table 3, harmonics must be calculated with the following procedure:
P0=Σ (Ki × Pi) [kVA]
Ki : Conversion factor (refer to Table 2)
Pi : Rated capacity of harmonic
generating equipment* [kVA]
i : Number indicating the conversion
circuit type
*Rated capacity: Determined by the capacity
of the applied motor and found in Table 5. It
should be noted that the rated capacity used
here is used to calculate a generated
harmonic amount and is different from the
power supply capacity required for actual
inverter drive.
2) Calculation of outgoing harmonic current
Outgoing harmonic current = fundamental wave current (value converterd from received
power voltage) × operation ratio × harmonic content
• Operation ratio: Operation ratio = actual load factor × operation time ratio
during 30 minutes
• Harmonic content: Found in Table 4.

INSTALLATION AND WIRING
2.3.3 Inverter-generated noise and reduction techniques
Some noises enter the inverter causing it to incorrectly operate, and others are
radiated by the inverter causing misoperation of peripheral devices. Though the
inverter is designed to be insusceptible to noise, it handles low-level signals, so it
requires the following basic measures to be taken. Also, since the inverter chops the
output at high carrier frequencies, it could generate noise. If these noises cause
peripheral devices to misoperate, measures should be taken to suppress noise. The
measures differ slightly depending on noise propagation paths.
1) Basic measures
! 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.
! Ground the inverter, motor, etc. at one point.
2) Measures against noise which enters and causes misoperation of the inverter
When devices which generate noise (devices which use magnetic contactors,
magnetic brakes, many relays, for example) are installed near the inverter, the
inverter may misoperate due to noise. The following measures must be taken:
! Provide surge suppressors for devices that generate noise to suppress noise.
! Fit data line filters to signal cables. (Refer to page 39)
! Ground the shields of the detector connection and control signal cables with cable
clamp metal.

3) Measures against noises which are radiated by the inverter causing misoperation of
peripheral devices.
Inverter-generated noises are largely classified into those radiated by the cables
connected to the inverter and inverter main circuit (I/O), those electromagnetically
and electrostatically inducted to the signal cables of the peripheral devices close to
the main circuit power supply, and those transmitted through the power supply
cables.

Measures
When devices which handle low-level signals and are susceptible to
misoperation due to noise (such as instruments, receivers and sensors)
are installed near the inverter and their signal cables are contained in the
same panel as the inverter or are run near the inverter, the devices may
be misoperated by air-propagated noise and the following measures must
be taken:
(1) Install easily affected devices as far away as possible from the
inverter.
(2) Run easily affected signal cables as far away as possible from the
inverter.
(3) Do not run the signal cables and power cables (inverter I/O cables) in
parallel with each other and do not bundle them.
(4) Insert line noise filters onto I/O and radio noise filters into inputs to
suppress cable-radiated noises.
(5) Use shielded cables for signal cables and power cables and run them
in individual metal conduits to further reduce 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 causing misoperation of the devices and the following
measures must be taken:
(1) Install easily affected devices as far away as possible from the
inverter.
(2) Run easily affected signal cables as far away as possible from the
inverter.
(3) Do not run the signal cables and power cables (inverter I/O cables) in
parallel with each other and do not bundle them.
(4) Use shielded cables for signal cables and power cables and run them
in individual metal conduits to further reduce effects.
When the power supplies of the peripheral devices are connected to the
power supply of the inverter within the same line, inverter-generated noise
may flow back through the power supply cables causing misoperation of
the devices and the following measures must be taken:
(1) Install the radio noise filter (FR-BIF) to the power cables (input cables)
of the inverter.
(2) Install the line noise filter (FR-BLF, FR-BSF01) to the power cables
(I/O cables) of the inverter.
When a closed loop circuit is formed by connecting the peripheral device
wiring to the inverter, leakage current may flow through the ground cable
of the inverter causing misoperation of the device. In such a case,
disconnection of the ground cable of the device may cause the device to
operate properly.

" Data line filter
Noise entry can be prevented by providing a data line filter for the detector or other
cable.
" Data examples
By using shielded cables as signal cables,
induction noise can be reduced greatly (1/10 to
1/100). Induction noise can also be reduced by
moving the signal cables away from the inverter
output cables.
(Separation of 30cm reduces noise to 1/2 to 1/3.)
By fitting the FR-BSF01 or BLF on the inverter
output side, induction noise to the signal cables
can be reduced.

2.3.4 Leakage currents and countermeasures
Due to the static capacitance existing in the inverter I/O wiring and motor, leakage
currents flow through them. Since their values depend on the static capacitance, carrier
frequency, etc., take the following measures.
(1) To-ground leakage currents
Leakage currents may flow not only into the inverter's own line but also into the other
lines through the ground cable, etc. These leakage currents may operate earth leakage
circuit breakers and earth leakage relays unnecessarily.
" Countermeasures
! If the carrier frequency setting is high, decrease the carrier frequency (Pr. 72) of
the inverter.
Note that motor noise increases. Selection of Soft-PWM (Pr. 240) will make it
unoffending.
! By using earth leakage circuit breakers designed for harmonic and surge
suppression (e.g. Mitsubishi's Progressive Super Series) in the inverter's own line
and other line, operation can be performed with the carrier frequency kept high
(with low noise).
" To-ground leakage current
! Note that a long wiring length will increase leakage currents. Decrease the carrier
frequency of the inverter to reduce leakage currents.
! Higher motor capacity leads to larger leakage currents.
(2) Line-to-line leakage currents
Harmonics of leakage currents flowing in static capacities between the inverter output
cables may operate the external thermal relay unnecessarily.

To ensure that the motor is protected not to be influenced by line-to-line leakage
currents, we recommend the protection method which uses a temperature sensor
to directly detect motor temperature.

INSTALLATION AND WIRING
" Installation and selection of no-fuse breaker
Install a no-fuse breaker (NFB) in the power supply side for protection of the inverter's
primary wiring. Refer to the previous table and choose the NFB according to the
inverter's power supply side power factor (which changes with the power supply
voltage, output frequency and load). Especially for a completely electromagnetic type
NFB, the one with a larger capacity must be selected since its operational
characteristics change with harmonic currents. (Check the data of the corresponding
breaker for confirmation.) Also, the earth leakage circuit breaker used should be
durable against harmonic/surge (such as Progressive Super Series).

2.3.7 Instructions for compliance with the European standards
(The products conforming to the Low Voltage Directive carry the CE mark.)
(1) EMC Directive
1) Our view of transistorized inverters for the EMC Directive
A transistorized inverter is a component designed for installation in a control box
and for use with the other equipment to control the equipment/device.
Therefore, we understand that the EMC Directive does not apply directly to
transistorized inverters. For this reason, we do not place the CE mark on the
transistorized inverters. (The CE mark is placed on inverters in accordance with
the Low Voltage Directive.) The European power drive manufacturers'
organization (CEMEP) also holds this point of view.
2) Compliance
We understand that the transistorized inverters are not covered directly by the
EMC Directive, but the machines/equipment into which they have been
incorporated are covered by the EMC Directive and must carry the CE marks.
Hence, we prepared the technical information "EMC Installation Guidelines"
(information number BCN-A21041-202) so that machines and equipment
incorporating transistorized inverters may conform to the EMC Directive more
easily.
3) Outline of installation method
Install an inverter using the following methods:
* Use the inverter with an European Standard-compliant noise filter.
* For wiring between the inverter and motor, use shielded cables or run them
in a metal piping and ground the cables on the inverter and motor sides with
the shortest possible distance.
* Insert a line noise filter and ferrite core into the power and control lines as
required.
Full information including the European Standard-compliant noise filter
specifications are written in the technical information "EMC Installation
Guidelines" (BCN-A21041-202). Please contact your sales representative.
(2) Low Voltage Directive
1) Our view of transistorized inverters for the Low Voltage Directive
Transistorized inverters are covered by the Low Voltage Directive (Standard to
comply with: DIN VDE0160).
2) Compliance
We have self-confirmed our inverters as products compliant to the Low Voltage
Directive and place the CE mark on the inverters.

INSTALLATION AND WIRING
3) Outline of instructions
* Connect the equipment to the earth securely. Do not use an earth leakage
circuit breaker as an electric shock protector without connecting the
equipment to the earth.
* Wire the earth terminal independently. (Do not connect two or more cables to
one terminal.)
* The wire size on pages 17 and 18 are shown for following conditions
! Ambient Temp : 40°C maximum
! Wire installation : On wall without ducts or conduits
If conditions are different from above, select appropriate wire according to
EN60204 ANNEX C TABLE 5.
* Use the no-fuse breaker and magnetic contactor which conform to the EN or
IEC Standard.
Design notice: Where residual-current-operated protective device (RCD) is
used for protection in case of direct or indirect contact, only
RCD of Type B is allowed on the supply side of this
Electronic Equipment (EE). Otherwise another protective
measure shall be applied such as separation of the EE from
the environment by double or reinforced insulation or
isolation of EE and supply system by a transformer. (Extract
from EN51078)
* Use the inverter under the conditions of overvoltage category II and
contamination level 2 or higher specified in IEC664.
(a) To meet the overvoltage category II, insert an EN or IEC standard-compliant
earthed star connection isolation transformer in the input of the inverter.
(b) To meet the contamination level 2, install the inverter in a control box
protected against ingress of water, oil, carbon, dust, etc. (IP54 or higher).
* On the input and output of the inverter, use cables of the type and size set
forth in EN60204 Appendix C.
* The operating capacity of the relay outputs (terminal symbols A, B, C) should
be 30VDC, 0.3A.
* The terminals indicated as the input and output terminals for control circuit on
page 13 are isolated safely from the main circuit.

Before starting operation, check the following:
" Safety
Perform test operation after making sure that safety is ensured if the machine
should become out of control.
" Machine
Make sure that the machine is free of damage.
" Parameters
Set the parameter values to match the operating machine (system) environment.
" Test operation
Perform test operation and make sure that the machine operates safely under light
load at a low frequency. After that, start operation.
Since the Pr. 240 "Soft-PWM setting" value is factory-set to select Soft-PWM
control, the tone is different from that in the conventional non-low acoustic noise
mode, this is not a fault.

Switched on when the monitored value is set to RWr0 by the monitor
command (RYC) switching on. Switched off when the monitor
command (RYC) is switched off.
Switched on when the set frequency is written to the inverter by the
frequency setting command (RYD) switching on. Switched off when
the frequency setting command (RYD) is switched off.
Switched on when the set frequency is written to the inverter by the
frequency setting command (RYE) switching on. Switched off when
the frequency setting command (RYE) is switched off.
Switched on on-completion of the processing corresponding to the
instruction code (RW W2) which is executed when the instruction code
execution request (RYF) switches on. Switched off when the
instruction code execution completion (RXF) is switched off.
Reserved for the system.
Switched on when an inverter error occurs (protective function is
activated).
Switched on when the inverter goes into the ready status on
completion of initial setting after power-on or hardware reset.
(Used as an interlock for read/write from/to the master station.)
Switched off when an inverter error occurs (protectiove function is
activated).
Using Pr. 190 to Pr. 192 (output terminal function selection), you can set the output signals of device No.s
RX2, RX6, RX7.
For details, refer to page 134.
Since operation differs with the condition setting switch (SW4) position of the master unit, use SW4 in the
OFF position. If you use SW4 in the ON position, the remote station ready signal remains ON if a
communication error occurs.

Note: 1. For E2PROM, write is made only once when RY2E is switched on.
2. If the set data is changed with RY2E on, it is not returned on the inverter.

Reads the remote input
(RX20 to RX3F) data of
buffer memory to M200-M231.
Switches on the error reset
request flag (RY1A).
Switches off the error reset
request flag (RY1A) if the
error status flag (RX1A) is off.
Writes M100-M131 data to the
remote outputs (RY20 to RY3F)
of buffer memory.
Note: 1. The above inverter reset using RY1A may be made only when an inverter
error occurs.
Also, inverter reset can be made independently of the operation mode.
2. When resetting the inverter using the instruction code execution request
(RYF) with the instruction code (FDH) and data (9696H), set the operation
mode to the CC-Link operation mode. (Refer to page 61 for the program
example.)

3.4.11 Instructions
(1) Programming instructions
1) Since the buffer memory data of the master station is kept transferred
(refreshed) to/from the inverters, the TO instruction need not be executed every
scan in response to data write or read requests.
The execution of the TO instruction every scan does not pose any problem.
2) If the FROM/TO instruction is executed frequently, data may not be written
reliably.
When transferring data between the inverter and sequence program via the
buffer memory, perform the handshake to confirm that data has been written
without fail.
Correct
TO instruction
Incorrect
TO instruction
Write completion
Write completion
(2) Operating and handling instructions
1) During CC-Link operation, the inverter only accepts commands from the PLC
and ignores any external operation command and any operation command from
the parameter unit.
2) If the same station number is set to different inverters, wrong data will be
transferred and normal communication cannot be made.
3) The inverter is brought to an alarm stop "E.OPT" if data communication stops for
more than the time set in Pr. 500 "communication error execution waiting time",
due to a PLC fault, an open CC-Link dedicated cable etc. during CC-Link
operation.
4) If the PLC (master station) is reset or PLC power is switched off during CC-Link
operation, data communication stops and the inverter is brought to an alarm stop
"E.OPT".
5) Do not set "1" in Pr. 77 "write inhibit selection" of the inverter. If the CC-Link
mode is selected with this setting, all parameters will be write-disabled.

Note: 1. When the fast-response current limit has been set in Pr. 156 (factory
setting), do not set the Pr. 22 value to 170% or more.
Torque will not be developed by doing so.
2. In vertical lift applications, make setting so that the fast-response current
limit is not activated. Torque may not be produced, causing a gravity drop.
CAUTION
Do not set a small value as the stall prevention operation current.
Otherwise, torque generated will reduce.
Test operation must be performed.
Stall prevention operation during acceleration may increase the
acceleration time.
Stall prevention operation during constant speed may change the speed
suddenly.
Stall prevention operation during deceleration may increase the

Description
Linear acceleration/deceleration is made up/down to the
preset frequency (factory setting).
For machine tool spindles
This setting is used when it is necessary to make
acceleration/deceleration in a short time up to the base
frequency or higher speed range.
In this acceleration/deceleration pattern, fb (base frequency)
is always the inflection point of an S shape, and you can set
the acceleration/deceleration time according to the reduction
in motor torque in the base frequency or higher constantoutput operation range.
For prevention of cargo collapse on conveyor, etc.
This setting provides S-shaped acceleration/deceleration
from f2 (current frequency) to f1 (target frequency), easing
an acceleration/deceleration shock. This pattern has an
effect on the prevention of cargo collapse, etc.
Note: For the acceleration/deceleration time, set the time required to reach the "base
frequency" in Pr. 3, not the "acceleration/deceleration reference frequency" in
Pr. 20. For details, refer to Pr. 7 and Pr. 8.

PARAMETERS
Note: 1. Automatic restart after instantaneous power failure uses a reduced-voltage
starting system in which the output voltage is raised gradually with the preset
frequency unchanged, independently of the coasting speed of the motor.
As in the FR-A024, a motor coasting speed detection system (speed search
system) is not used but the output frequency before an instantaneous power
failure is output. Therefore, if the instantaneous power failure time is longer
than 0.2s, the frequency before the instantaneous power failure cannot be
stored and the inverter will start at 0Hz.
2. The SU and FU signals are not output during restart but are output after the
restart cushion time has elapsed.
CAUTION
When automatic restart after instantaneous power failure has been
selected, the motor and machine will start suddenly (after the reset time
has elapsed) after occurrence of an instantaneous power failure.
Stay away from the motor and machine.
When you have selected automatic restart after instantaneous power
failure, apply the supplied CAUTION seals in easily visible places.
STOP
When the start signal is turned off or the RESET
key is pressed during the
cushion time for automatic restart after instantaneous power failure,
deceleration starts after the automatic restart cushion time set in Pr. 58

has elapsed.

The other way of making a restart other than the above method is to perform a powerreset or to make a reset with the inverter reset terminal.
Note: 1. By entering the reset signal (RES) during operation, the inverter shuts off
output while it is reset, the data of the electronic overcurrent protection and
regenerative brake duty are reset, and the motor coasts.
2. The PU disconnection detection function judges that the PU is disconnected
when it is removed from the inverter for more than 1 second.
If the PU had been disconnected before power-on, it is not judged as an
alarm.
3. To resume operation, reset the inverter after confirming that the PU is
connected securely.
4. The Pr. 75 value can be set any time. Also, if parameter (all) clear is
executed, this setting will not return to the initial value.
5. When the inverter is stopped by the PU stop function, PS is displayed on the
PU but an alarm is not output.
When the PU connector is used for RS-485 communication operation, the
reset selection and PU stop selection functions are valid but the PU
disconnection detection function is invalid.

What is auto tuning?
(1) The general-purpose magnetic flux vector control system gets the best
performance from the motor for operation.
(2) Using the offline auto tuning function to improve the operational performance of
the motor.
When you use the general-purpose magnetic flux vector control, you can perform the
offline auto tuning operation to calculate the motor constants automatically.
! Offline auto tuning is made valid only when Pr. 80 is set to other than "9999" to
select the general-purpose magnetic flux vector control.
! The Mitsubishi standard motor (SF-JR0.4kW or more) or Mitsubishi constant-torque
motor (SF-JRCA 4-pole motor of 0.4kW to 7.5kW) allows general-purpose magnetic
flux vector control operation to be performed without using the offline auto tuning
function. However, if any other motor (Motor made of the other manufacturers or SFJRC, etc.) is used or the wiring distance is long, using the offline auto tuning function
allows the motor to be operated with the optimum operational characteristics.
! Offline auto tuning
Automatically measures the motor constants used for general-purpose magnetic flux
vector control.
" Offline auto tuning can be performed with the load connected.
" The offline auto tuning status can be monitored with the control panel or PU
(FR-PU04).
" Only a static auto tune can be performed.
" Office auto tuning is available only when the motor is at a stop.
! Tuning data (motor constants) can be copied to another inverter with the PU
(FR-PU04).

The motor is connected.
The motor capacity is equal to or one rank lower than the inverter capacity.
Special motors such as high-slip motor and high-speed motor cannot be tuned.
The motor may move slightly. Therefore, fix the motor securely with a mechanical
brake, or before tuning, make sure that there will be no problem in safety if the
motor runs.
*This instruction must be followed especially for vertical lift applications.
If the motor runs slightly, tuning performance is unaffected.

Note: 1. The R1 motor constant measured during in the offline auto tuning is stored
as a parameter and its data is held until the offline auto tuning is performed
again.
2. An instantaneous power failure occurring during tuning will result in a tuning
error.
After power is restored, the inverter goes into the ordinary operation mode.
Therefore, when STF (STR) is on, the motor runs in forward (reverse)
rotation.
3. Any alarm occurring during tuning is handled as in the ordinary mode. Note
that if an error retry has been set, retry is ignored.

If any error is found in the data received by the inverter, its definition is sent back
to the computer together with the NAK code. (Refer to page 125.)
121
PARAMETERS
Note: 1. When the data from the computer has an error, the inverter will not accept
that data.
2. Any data communication, e.g. run command, monitoring, is started when the
computer gives a communication request. Without the computer's command,
the inverter does not return any data. For monitoring, therefore, design the
program to cause the computer to provide a data read request as required.
3. When accessing the parameter settings, data for link parameter expansion
setting differs between the parameters as indicated below:

05H: Pr. 500 to Pr. 502 values are accessible.
09H: Pr. 990, Pr. 991 values are accessible.
CAUTION
When the inverter's permissible communication time interval is not set,
interlocks are provided to disable operation to prevent hazardous
conditions. Always set the communication check time interval before
starting operation.
Data communication is not started automatically but is made only once
when the computer provides a communication request. If communication
is disabled during operation due to signal cable breakage etc, the inverter
cannot be stopped. When the communication check time interval has
elapsed, the inverter will come to an alarm stop (E.PUE).
The inverter can be coasted to a stop by switching on its RES signal or
by switching power off.
If communication is broken due to signal cable breakage, computer fault
etc, the inverter does not detect such a fault. This should be fully noted.

PARAMETERS
CAUTION
The zero current detection level setting should not be too high, and the
zero current detection time setting should not be too long. Otherwise, the
detection signal may not be output when torque is not generated at a low
output current.
To prevent the machine and equipment from resulting in hazardous
conditions by use of the zero current detection signal, install a safety
backup such as an emergency brake.

You can make settings to disable stall prevention caused by overcurrent and to disable
the inverter from an overcurrent trip if an excessive current occurs due to sudden load
variation or turning the inverter's output side ON-OFF (to disable the fast-response
current limit which limits the current).
" Stall prevention
If the current exceeds the limit value, the output frequency of the inverter is
automatically varied to reduce the current.
" Fast-response Current limit
If the current exceeds the limit value, the output of the inverter is shut off to prevent
an overcurrent.

Note 1: When "Operation not continued for OL signal output" is selected, the
"E.OLT" alarm code (stopped by stall prevention) is displayed and operation
stopped.
(Alarm stop display "E.OLT")
2: If the load is heavy, the lift is predetermined, or the acceleration/deceleration
time is short, the stall prevention may be activated and the motor not
stopped in the preset acceleration/deceleration time. Therefore, set optimum
values to the Pr. 156 and stall prevention operation level.
3: In vertical lift applications, make setting so the fast-response current limit is
not cativated. Torque may not be produced, causing a gravity drop.
CAUTION
Always perform test operation.
Stall prevention operation performed during acceleration may increase
the acceleration time.
Stall prevention operation performed during constant speed may cause
sudden speed changes.
Stall prevention operation performed during deceleration may increase
the deceleration time, increasing the deceleration distance.

You can make invalid the output phase failure protection (E.LF) function which stops
the inverter output if one of the three phases (U, V, W) on the inverter's output side
(load side) becomes open.
Choose "without output phase failure protection" when the motor capacity is smaller
than the inverter capacity (when the output current is less than approximately 25% of
the rated inverter current value as a guideline), since performing operation in such a
case may activate output phase failure protection.

Note: 1. A communication error [E.OPT (fault data: A0H)] is a fault on the communication

inside the inverter.
2. The alarm output is the ABC contact output or alarm bit output.
3. If the Pr. 502 setting is 1 or 2, the deceleration time is the ordinary
deceleration time setting (Pr. 8, Pr. 44, Pr. 45).
4. The acceleration time at restart is the ordinary acceleration time setting (Pr. 7,
Pr. 44).
5. If the Pr. 502 setting is 2, the operation command/speed command at restart
follows the command before occurrence of a fault.
6. For the setting of alarm output, the fault definition is stored in the alarm history.
(Write to the alarm history is performed when the alarm output is provided.)
If the alarm output is not provided, the fault definition overwrites the alarm
indication of the alarm history temporarily but is not stored.
After the fault is cleared, the alarm indication is reset and returns to the
ordinary monitor and the alarm history returns to the original alarm history.
7. When a communication line fault, which occurred at the Pr. 502 setting of 2, is
cleared during deceleration, acceleration restarts at that point. (Acceleration
does not restart at occurrence of a CC-Link microcomputer fault.)

5.1 Errors (Alarms)
If any fault has occurred in the inverter, the corresponding protective function is
activated to bring the inverter to an alarm stop and automatically give the
corresponding error (alarm) indication on the PU display.
If your fault does not correspond to any of the following errors or if you have any other
problem, please contact your sales representative.
• Retention of alarm output signal .... When the magnetic contactor (MC) provided on
the 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 indication ............................. When the protective function is activated, the
operation panel display automatically switches to
the above indication.
• Resetting method .......................... When the protective function is activated, the
inverter output is kept stopped. Unless reset,
therefore, the inverter cannot restart. Switch
power off once, then on again.
• When the protective function is activated, take the corresponding corrective action,
then reset the inverter, and resume operation.

Motor overload shut-off (electronic overcurrent protection)
(E. THM) (Note 1)
The electronic overcurrent protection in the inverter detects
motor overheat due to overload or reduced cooling capability
during constant-speed operation to stop the inverter output.
When a multi-pole motor or two or more motors are run,
provide a thermal relay in the output side of the inverter.
Check the motor for use under overload.
• Reduce the load weight.
• For the constant-torque motor, change the Pr. 71 setting to
the constant-torque motor setting.

5.3 Precautions for Maintenance and Inspection
PROTECTIVE FUNCTIONS
5.3 Precautions for Maintenance and Inspection
The transistorized inverter is a static unit mainly consisting of semiconductor devices.
Daily inspection must be performed to prevent any fault from occurring due to adverse
influence by the operating environment, such as temperature, humidity, dust, dirt and
vibration, changes in the parts with time, service life, and other factors.
5.3.1 Precautions for maintenance and inspection
When the maintenance/inspection of the inverter is to be performed in the CC-Link
communication status, remove the terminal block for CC-Link communication signals.
Therefore, when more than 10 minutes have elapsed after power-off, make sure that
the voltage across the main circuit terminals P - N (+ - −) of the inverter is 30VDC or
less using a tester, etc. Then, access the inverter for inspection.
5.3.2 Check items
(1) Daily inspection
$ Check the following:
1) Motor operation fault
2) Improper installation environment
3) Cooling system fault
4) Unusual vibration and noise
5) Unusual overheating and discoloration
$ During operation, check the inverter input voltages using a meter.
(2) Cleaning
Always run the inverter in a clean state.
When cleaning the inverter, gently wipe dirty areas with a soft cloth immersed in
neutral detergent or ethanol.
Note:
Do not use solvent, such as acetone, benzene, toluene and alcohol, as they
will cause the inverter surface paint to peel off.
Do not use detergent or alcohol to clean the display and other sections of the
parameter unit (FR-PU04) as these sections may deform.

5.3.3 Periodic inspection
Check the areas inaccessible during operation and requiring periodic inspection.
1) Cooling system: .........Clean the air filter, etc.
2) Screws and bolts: .......These parts may become loose due to vibration, temperature
changes, etc. Check that they are tightened securely and
retighten as necessary.
3) Conductors and insulating materials: Check for corrosion and damage.
4) Insulation resistance: Measure.
5) Cooling fan, smoothing capacitor: Check and change if necessary.
5.3.4 Insulation resistance test using megger
1) Before performing the insulation resistance test using a megger on the external
circuit, disconnect the cables from all terminals of the inverter so that the test voltage
is not applied to the inverter.
2) For the continuity test of the control circuit, use a meter (high resistance range) and
do not use the megger or buzzer.
3) For the inverter, conduct the insulation resistance test on the main circuit only as
shown below and do not perform the test on the control circuit. (Use a 500VDC
megger.)

! Checking the inverter and converter modules
<Preparation>
(1) Disconnect the external power supply cables (R(L1), S(L2), T(L3)) and motor cables
(U, V, W).
(2) Prepare a meter. (Use 100Ω range.)
<Checking method>
Change the polarity of the meter alternately at the inverter terminals R(L1), S(L2),
T(L3), U, V, W, P(+) and N(−), and check for continuity.
Note: 1. Before measurement, check that the smoothing capacitor is discharged.
2. At the time of continuity, the measured value is several to several ten’s-of
ohms depending on the number of modules, number of parallel modules,
circuit tester type, etc. If all measured values are almost the same, the
modules are without fault.

5.3.7 Replacement of parts
The inverter consists of many electronic parts such as semiconductor devices.
The following parts may deteriorate with age because of their structural or physical
characteristics, leading to reduced performance or failure of the inverter. For preventive
maintenance, the parts must be changed periodically.

Note: For part replacement, contact the nearest Mitsubishi FA center.
(1) Cooling fan
The cooling fan cools heat-generating parts such as the main circuit semiconductor
devices. The life of the cooling fan bearing is usually 10,000 to 35,000 hours. Hence,
the cooling fan must be changed every 2 to 3 years if the inverter is run continuously.
When unusual noise and/or vibration is noticed during inspection, the cooling fan must
be changed immediately.

! Removal
1) Remove the wiring cover. (Refer to page 8.)
2) Unplug the fan connector.
The cooling fan is plugged into the cooling fan
connector beside the inverter terminal block.
Unplug the connector and separate the inverter
from the cooling fan.
3) Remove the cooling fan cover.
Push the cover in the direction of arrow and
pull it down.
4) Remove the cooling fan and cooling fan cover.
The cooling fan is secured by the fixing
catches.
Disengage the fixing catches to remove the
cooling fan and cooling fan cover.

PROTECTIVE FUNCTIONS
! Reinstallation
1) After confirming the orientation of the fan,
reinstall the fan to the cover so that the arrow
on the left of "AIR FLOW" faces in the opposite
direction of the fan cover.
Note: If the air flow is set in the wrong
direction, the inverter life can be
shorter.
2) Reinstall the fan cover to the inverter.
Run the cable through the wiring groove to
prevent it from being caught between the
chassis and cover.
3) Reconnect the cable to the connector.
4) Reinstall the wiring cover.
AIR FLOW
(For 5.5K, 7.5K)
* Wire the cables using care so that they
are not caught by the cooling fan.
(2) Smoothing capacitors
A large-capacity aluminum electrolytic capacitor is used for smoothing the DC in the
main circuit, and an aluminum electrolytic capacitor is also used for stabilizing the
control power in the control circuit.
Their characteristics are adversely affected by ripple current, etc. When the inverter is
operated in an ordinary, air-conditioned environment, change the capacitors about
every 5 years. When 5 years have elapsed, the capacitors will deteriorate more rapidly.
Check the capacitors at least every year (less than six months if the life will be expired
soon). Check the following:
1) Case (side faces and bottom face for expansion)
2) Sealing plate (for remarkable warp and extreme crack)
3) Appearance, external cracks, discoloration, leakage.
When the measured capacitance of the capacitor has reduced below 85% of the
rating, change the capacitor.

Note: 1. The applicable motor capacity indicated is the maximum capacity applicable
when a Mitsubishi 4-pole standard motor is used.
2. The rated output capacity indicated assumes that the output voltage is 230V.
3. The overload capacity indicated in % is the ratio of the overload current to the
inverter's rated current. For repeated duty, allow time for the inverter and
motor to return to or below the temperatures under 100% load.
4. The maximum output voltage cannot exceed the power supply voltage. The
maximum output voltage may be set as desired below the power supply
voltage. However, the crest value of the inverter output voltage remains
unchanged from the DC bus voltage.
5. The power supply capacity changes with the values of the power supply side
inverter impedances (including those of the input reactor and cables).
6. The rated output current in the parentheses applies when low acoustic noise
operation is to be performed at the ambient temperature higher than 40°C with
the Pr. 72 (PWM frequency selection) value set to 2kHz or higher.
7. When using a DC power supply
(1) The guideline for the power supply voltage fluctuation range is 280VDC
±10%, and usually use the power supply at or below 300VDC.
(2) When DC power is switched on, a larger inrush current flows than in AC
power. The number of power-on times should be minimized.
(3) 300VDC must be reserved to make the torque characteristic equal to when
AC power supply is used.
