A-2
(4) Operation
WARNING
! The [STOP] key is valid only when the appropriate function setting has been made.
Prepare an emergency stop switch separately.
! Make sure that the start signal is off before resetting the inverter alarm. A failure to
do so may restart the motor suddenly.
! The load used should be a three-phase induction motor only. Connection of any
other electrical equipment to the inverter output may damage the equipment.
! Do not modify the equipment.
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 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 the inverter which had been stored for a long period, always perform inspection and test operation.
(5) Emergency stop
CAUTION
! Provide a safety backup such as an emergency brake which will prevent the
machine and equipment from hazardous conditions if the inverter fails.

Basic Configuration
1.1 Basic Configuration
Power supply
Use within the permissible power supply specifications of the
inverter. (Refer to page 178.)
(NFB)
or
(ELB)
No-fuse breaker or earth leakage circuit breaker
The breaker must be selected carefully since an inrush current
flows in the inverter at power-on. (Refer to page 22.)
(MC)
Magnetic contactor
Do not use this magnetic contactor to start and stop the inverter.
Doing so will cause the inverter life to be shorter. (Refer to page
22.)
AC reactor
(FR-BAL)
Installation of reactors
The reactors must be used when the power factor is to be
improved or the inverter is installed near a large power supply
system (500kVA or more and wiring distance within 10m). Make
selection carefully. (Refer to page 22.)
Inverter
Earth
(Ground)
Earth (Ground)
DC reactor
(FR-BEL)
The inverter life is influenced by ambient temperature. The
ambient temperature should be as low as possible within the
permissible range. (Refer to page 4.)
Wrong wiring might lead to damage of the inverter. The control
signal wires must be kept fully away from the main circuit to
protect them from noise. (Refer to page 5.)
Devices connected to the output
Do not connect a power factor correction capacitor, surge
suppressor or radio noise filter to the output side.
Earth (Ground)
To prevent an electric shock, always earth (ground) the motor and
inverter.
For reduction of induction noise from the power line of the
inverter, it is recommended to wire the earth (ground) cable by
returning it to the earth (ground) terminal of the inverter.
(For details of noise reduction techniques, refer to page 28.)
REMARKS
•When using the PLC function, refer to page 35 for wiring and to page 98 for details.
•When using the CC-Link function, refer to page 36 for wiring and to page 140 for details.

Earthing (Grounding) Precautions
! Wiring length
100m maximum
CAUTION
•When the wiring length of the 0.1K or 0.2K is 30m or more, use the carrier
frequency at 1kHz.
•If the inverter-to-motor wiring distance is long, the motor torque will decrease
due to a voltage drop in the main circuit cables especially at low frequency
output. Use thick cables for wiring to make a voltage drop less than 2%.
1.6 Earthing (Grounding) Precautions
! Leakage currents flow in the inverter. To prevent an electric shock, the inverter and
motor must be earthed (grounded). (Class D earthing (grounding), earthing
(grounding) resistance 100Ω maximum)
! Use the dedicated earth (ground) terminal to earth (ground) the inverter. (Do not use
the screw in the casing, chassis, etc.)
Use a tin plated* crimping terminal to connect the earth (ground) cable. When
tightening the screw, be careful not to damage the threads.
*Plating should not include zinc.
! Use the thickest possible earth (ground) cable. Use the cable whose size is equal to
or greater than that indicated below, and minimize the cable length. The earthing
(grounding) point should be as near as possible to the inverter.

For use as a product compliant with the Low Voltage Directive, use PVC cable
whose size is indicated within parentheses.
! Earth (Ground) the motor on the inverter side using one cable of the 4-core cable.
CAUTION
If the inverter is run in the low acoustic noise mode, more leakage currents flow due to
fast switching operations than in the non-low acoustic noise mode. Always use the
inverter and motor after earthing (grounding) them. When earthing (grounding) the
inverter, always use its earth (ground) terminal.

! Change the jumper connector position
using tweezers, a pair of long-nose pliers,
etc. Change the jumper connector position
before switching power on.
CAUTION
•Make sure that the front cover is installed securely.
•The front cover is fitted with the capacity plate and the inverter unit with the
rating plate. Since these plates have the same serial numbers, always replace
the removed cover onto the original inverter.
•The sink-source logic change-over connector must be fitted in only one of
those positions. If it is fitted in both positions at the same time, the inverter
may be damaged.

To start and stop the motor, first switch on the input power supply of the inverter
(switch on the magnetic contactor, if any, in the input circuit during preparation for
operation), then start the motor with the forward or reverse rotation start signal.
POINT
With "1" factory-set in Pr. 507 "inverter operation lock mode setting", the start

Connection Example
3) After the start signal has been input, the inverter starts operating when the frequency setting
signal reaches or exceeds the "starting frequency" set in Pr. 13 (factory-set to 0.5Hz).
If the motor load torque is large or the "torque boost" set in Pr. 0 is small, the inverter may be
overloaded due to insufficient torque.
If the "minimum frequency" set in Pr. 2 (factory setting = 0Hz) is 6Hz, for example, merely
entering the start signal causes the running frequency to reach the minimum frequency of 6Hz
according to the "acceleration time" set in Pr. 7.
4) To stop the motor, operate the DC injection brake for the period of "DC injection brake
operation time" set in Pr. 11 (factory setting = 0.5s) at not more than the DC injection brake
operation frequency or at not more than 0.5Hz.
To disable the DC injection brake function, set 0 in either of Pr. 11 "DC injection brake
operation time" and Pr. 12 "DC injection brake voltage".
In this case, the motor is coated to a stop at not more than the frequency set in Pr. 10 "DC
injection brake operation frequency" (0 to 120Hz variable) or at not more than 0.5Hz (when
the DC injection brake is not operated).
5) If the reverse rotation signal is input during forward rotation or the forward rotation signal is
input during reverse rotation, the inverter is decelerated and then switched to the opposite
output polarity without going through the stop mode.

The motor is decelerated according to the preset deceleration time and is stopped
by operating the DC injection brake at 3Hz or less. By using terminal MRS, the
motor is coasted to a stop.

External thermal relay input: Pr. 60 to Pr. 63, Pr. 65, Pr. 505 setting "7"
When the external thermal relay or thermal relay built in
the motor (e.g. thermal protector) is actuated, the
inverter output is shut off and an alarm signal is given to
keep the motor stopped to protect the motor from
overheat. If the thermal relay contact is reset, the motor
is not restarted unless the reset terminal RES-SD are
shorted for more than 0.1s and then opened or power-on
reset is performed.
The function may therefore be used as an external
emergency stop signal input.

Used to reset the alarm stop state established when the inverter's protective function
is activated. The reset signal immediately sets the control circuit to the initial (cold)
status, e.g. initializes the electronic overcurrent protection circuit. It shuts off the
inverter output at the same time. During reset, the inverter output is kept shut off. To
give this reset input, short terminals RES-SD for more than 0.1s. When the shorting
time is long, the operation panel or parameter unit displays the initial screen, which is
not a fault.
Operation is enabled after terminals RES-SD are opened (after about 1s).
The reset terminal is used to reset the inverter alarm stop state. If the reset terminal is
shorted, then opened while the inverter is running, the motor may be restarted during
coasting (refer to the timing chart below) and the output may be shut off due to
overcurrent or overvoltage.
Setting either of "1" and "15" in reset selection Pr. 75 allows the accidental input of the

Choose the NFB type that meets the power supply capacity.
The sizes of the cables assume that the wiring length is 20m.
The power factor may be slightly less.
For installations in the United States or Canada, select the UL/cUL-listed breaker.
REMARKS
Secondary side measuring instruments
If the wiring length between the inverter and motor is long, the measuring instruments and CT
may generate heat due to line-to-line leakage currents. Therefore, select the devices that have
sufficient current ratings.
1.10.2 Leakage current and installation of earth (ground)
leakage circuit breaker
Due to static capacitances existing in the inverter I/O wiring and motor, leakage
currents flow through them. Since their values depend on the static capacitances,
carrier frequency, etc., take the following countermeasures.
(1) To-earth (ground) leakage currents
Leakage currents may flow not only into the inverter's own line but also into the
other line through the earth (ground) cable, etc. These leakage currents may
operate earth (ground) leakage circuit breakers and earth (ground) leakage
relays unnecessarily.
22
Peripheral Devices
! Countermeasures
• If the carrier frequency setting is high, decrease the carrier frequency (Pr. 72) of
the inverter.
Note that motor noise increases.
• Using earth leakage circuit breakers designed for harmonic and surge suppression
in the inverter's own line and other line, operation can be performed with the
carrier frequency kept high (with low noise).

! Countermeasures
• Use the electronic overcurrent protection of the inverter.
• Decrease the carrier frequency. Note that motor noise increases.
To ensure that the motor is protected against line-to-line leakage currents, it is
recommended to use a temperature sensor to directly detect motor temperature.
! Installation and selection of no-fuse breaker
On the power receiving side, install a no-fuse breaker (NFB) to protect the primary
wiring of the inverter. Which NFB to choose depends on the power supply side
power factor (which changes with the power supply voltage, output frequency and
load) of the inverter. Especially as the completely electromagnetic type NFB
changes in operational characteristic with harmonic currents, you need to choose
the one of a little larger capacity. (Check the data of the corresponding breaker.) For
the earth leakage circuit breaker, use our product designed for harmonic and surge
suppression. (Refer to page 25 for the recommended models.)
CAUTION
•Choose the NFB type according to the power supply capacity.
•To protect the motor from overheat, the inverter has protective functions with
electronic thermal relay. However, when operating two or more motors with a
single inverter or running a multi-pole motor, for example, provide an
overcurrent relay (OCR) between the inverter and motor. In this case, set the
electronic thermal relay of the inverter for 0A, and set the overcurrent relay for
1.0 time the current value at 50Hz on the motor rating plate, or 1.1 times the
current value at 60Hz, plus the line-to-line leakage current.

(3) Selecting the rated sensitivity current for the earth (ground) leakage
breaker
CAUTION
•On the power receiving side, install a no-fuse breaker (NFB) to protect the
primary wiring of the inverter. Selection of NFB depends on the power supply
side power factor (which changes with the power supply voltage, output
frequency and load) of the inverter. Especially as the completely
electromagnetic type NFB changes in operational characteristic with
harmonic currents, you need to choose the one of a little larger capacity. For
the earth (ground) leakage circuit breaker, use our product designed for
harmonic and surge suppression.
When using the earth (ground) leakage breaker with the inverter circuit, select its rated
sensitivity current as follows, independently of the PWM carrier frequency.

CAUTION
•The earth (ground) leakage circuit breaker should be installed to the
primary (power supply) side of the inverter.
•In the
connection neutral point grounding system, the sensitivity current
becomes worse for earth (ground) faults in the inverter secondary side.
Hence, the protective earthing (grounding) of the load equipment should be
10Ω
Ω or less.
•When the breaker is installed in the secondary side of the inverter, it may
be unnecessarily operated by harmonics if the effective value is less than
the rating.
In this case, do not install the breaker since the eddy current and
hysteresis loss increase and the temperature rises.

1.10.3 Power-off and magnetic contactor (MC)
(1) Inverter's primary side magnetic contactor (MC)
On the inverter's primary side, it is recommended to provide an MC for the following
purposes (refer to page 22 for selection):
1) To release the inverter from the power supply when the inverter's protective function
is activated or when the drive is not functioning (e.g. emergency stop operation).
2) When the external terminal (terminal STF or STR) is used for operation, provide an
MC in the primary side to prevent an accident caused by an automatic restart made
at power restoration after an instantaneous power failure, etc. and to ensure safety
during maintenance work. When the parameter unit is used for operation, an MC
cannot be used to make a start since an automatic restart is not made after power
restoration. Though the inverter can be stopped with the primary side MC, it is
coasted to a stop.
3) To rest the inverter for a long time.
The control power supply for inverter is always running and consumes a little power.
When stopping the inverter for a long time, switching inverter power off saves power
slightly.
4) To separate the inverter from the power supply to ensure safety of maintenance/
inspection work.
As the inverter's primary MC is used for the above purposes, select the one of class
JEM1038-AC3 for the inverter input side current when making an emergency stop
during normal operation.
CAUTION
Do not start and stop the inverter frequently using a magnetic contactor. Such
operation can cause the inverter to fail. (The switching life in the inverter input
circuit is about 100,000 times).
(2) Handling of the inverter's secondary side magnetic contactor
In principle, a magnetic contactor provided between the inverter and motor should
not be switched from OFF to ON during operation. Doing so may cause a large
inrush current to flow, leading to a stop due to overcurrent shutoff. If an MC is
provided for such purposes as switch-over to a commercial power supply, the MC
should be switched on/off after the inverter and motor have stopped.

1.10.4 Regarding the installation of the power factor
improving reactor
When the inverter is installed near a large-capacity power transformer (500kVA or
more at the wiring length of 10m or less) or the power capacitor is to be switched, an
excessive peak current will flow in the power supply input circuit, damaging the
converter circuit. In such a case, always install the power factor improving reactor (FRBEL or FR-BAL).

INSTALLATION AND WIRING
CAUTION
•The power factor improving capacitor and surge suppressor on the inverter
output side may be overheated or damaged by the harmonic components of
the inverter output. Also, since an excessive current flows in the inverter to
activate overcurrent protection, do not insert a capacitor and surge
suppressor. Use a power factor improving reactor for power factor
improvement.
•If a surge voltage occurs in the power supply system, this surge energy may
flow into the inverter, causing the inverter to display OV1, OV2 or OV3 and
come to an alarm stop. In such a case, also install the optional FR-BEL or FRBAL power factor improving reactor.
Peripheral Devices
1.10.5 Regarding noises and the installation of the noise filter
Some noises enter the inverter causing it to malfunction and others are generated by
the inverter causing peripheral devices to malfunction. Though the inverter is designed
to be insusceptible to noises, it handles low-level signals, so it requires the following
general countermeasures to be taken.
(1) General countermeasures
• Do not run the power cables (I/O cables) and signal cables of the inverter in parallel
with each other and do not bundle them.
• Use twisted shield cables for the detector connecting and control signal cables and
connect the sheathes of the shield cables to terminal SD.
• Earth (Ground) the inverter, motor, etc. at one point.
• Capacitances exist between the inverter's I/O wiring, other cables, earth (ground)
and motor, through which leakage currents flow to cause the earth (ground) leakage
circuit breaker, earth (ground) leakage relay and external thermal relay to operate
unnecessarily. To prevent this, take appropriate measures, e.g. set the carrier
frequency in Pr. 72 to a low value, use an earth (ground) leakage circuit breaker
designed for suppression of harmonics and surges, and use the electronic
overcurrent protection built in the inverter.
• The input and output of the inverter main circuit include high-degree harmonics,
which may disturb communication devices (AM radios) and sensors used near the
inverter. In this case, disturbance can be reduced by mounting the FR-BIF radio
noise filter (for input side only) or FR-BSF01 line noise filter.

1.10.7 Power 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 harmonics.
1) [Harmonic suppression guideline for household appliances and general-purpose
products]
The "harmonic suppression guideline for household appliances and generalpurpose products" issued by Ministry of Economy, Trade and Industry (formerly
Ministry of International Trade and Industries) in September, 1994 applies to the
FR-C500 series. By installing the FR-BEL or FR-BAL power factor improving
reactor, this product complies with the "harmonic suppression techniques for
transistorized inverters (input current 20A or less)" established by the Japan
Electrical Manufacturers' Association.
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]

Design Information
1.15 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 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 (e.g. STF) of the control circuit.
5) Make sure that the specifications and rating match the system requirements.

function disable but for STF, STR and RL terminal function enable in the factory
setting status (Pr. 507=0) when the built-in PLC function is in a STOP status or there
is no program, and the inverter operates if any of the sensors is blocked. (Refer to

REMARKS
Using the parameter unit (FR-PU04), parameter copy allows the parameter
values to be copied to another inverter (only the FR-C500 series).
After batch-reading the parameters of the copy source inverter, you can
connect the parameter unit to the copy destination inverter and batch-write
the parameters.

•Assuming that the base frequency voltage is 100%, set the 0Hz voltage in %.
! When using an inverter-dedicated motor (constant-torque motor), make setting as
indicated below:
•FR-C520-0.1K to 0.75K ... 6%, FR-C520-1.5K to 3.7K ...... 4%
If you leave the factory setting as it is and change the Pr. 71 value to the setting for
use of the constant-torque motor, the Pr. 0 setting changes to the above value.
CAUTION
•A too large setting may cause the motor to overheat or result in an
overcurrent trip. The guideline is about 10% at the greatest.

•In Pr. 3, set the base frequency (motor's rated frequency).
When running the standard motor, generally set the "base frequency" to the rated
frequency of the motor. When running the motor using commercial power supplyinverter switch-over operation, set the base frequency to the same value as the
power supply frequency.
When the frequency given on the motor's rating plate is only "50Hz", always set the
"base frequency" to "50Hz".
Leaving the base frequency unchanged from "60Hz" may make the voltage too low
and the torque insufficient, resulting in an overload trip.

•Set the rated current [A] of the motor.
(Normally set the rated current value at 50Hz if the motor has both 50Hz and 60Hz
rated currents.)
•Setting "0" in Pr. 9 disables the electronic thermal O/L relay (motor protective
function). (The protective function of the inverter is activated.)
•When using a Mitsubishi constant-torque motor, first set "1" in Pr. 71 "applied motor"
to choose the 100% continuous torque characteristic in the low-speed range. Then,
set the rated motor current in Pr. 9 "electronic thermal O/L relay".
CAUTION
• When two or more motors are connected to the inverter, they cannot be
protected by the electronic overcurrent protection. Install an external thermal
relay to each motor.
• When the difference between the inverter and motor capacities is large and
the setting is small, the protective characteristics of the electronic
overcurrent protection will be deteriorated. In this case, use an external
thermal relay.
• A special motor cannot be protected by the electronic overcurrent protection.
Use an external thermal relay.

3.3.10 Stall prevention function and current limit function
(Pr. 21, Pr. 22)
You can make setting to disable stall prevention caused by overcurrent and to
prevent the inverter from resulting in an overcurrent trip if an excessive current
occurs due to sudden load variation or ON-OFF, etc. in the output side of the
running inverter.
• 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.

Basic Functions
Stall prevention (Pr. 22)
Set the output current level at which the output frequency will be adjusted to
prevent the inverter from stopping due to overcurrent, etc.

Range
22
Stall prevention operation level
150%
0 to 200%
<Setting>
•Generally, set 150% (factory setting) in Pr. 22 "stall prevention operation level".
Setting "0" in Pr. 22 disables stall prevention operation.
CAUTION
•* When "Operation not continued for OL signal output" is selected, the "OLT"
alarm code (stopped by stall prevention) is displayed and operation
stopped.
(Alarm stop display "
")
•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. 21 and stall prevention operation level.
•When the fast-response current limit has been set in Pr. 21 (factory setting),
torque will not be provided at the Pr. 22 setting of 170% or higher. At this time,
make setting so that the fast-response current limit is not activated.
•In vertical lift applications, make setting so that the fast-response current limit
is not activated. Torque may not be produced, causing a drop due to gravity.
CAUTION
Do not set a small value as the stall prevention operation current.
Otherwise, torque generated will reduce.
Test operation must be performed.

INVERTER FUNCTIONS
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.

Operation Selection Function Parameters
(1) Operation using the PLC function
The "P.RUN" LED that indicates the PLC function operation is lit when the SQ
signal is turned on. When the following setting is to be made in the sequence
program, the PU operation mode (Pr. 79 = 0, 1 or 3) must be selected.
• Running frequency write
• Inverter parameter rewrite
• Inverter parameter clear or all clear
(2) Operation using CC-Link communication
CC-Link communication operation cannot be performed unless the "PU" and
"EXT" LEDs on the operation panel flicker slowly.
In either of the following two methods, light up the "L.RUN" LED.
POINT
Set "0" (factory setting) or "2" in Pr. 79 "operation mode selection".
<Method 1: Set "H0000" in device D9143 "operation mode selection write".>
• Create an operation mode setting program using GX Developer. (Refer to page 122.)
REMARKS
The operation mode can also be set using an RS-485 communication user program. (Refer
to page 79.)
POINT
•Priority of X5 and X15 (SQ signal)
Always short X5-SD to execute (RUN) the built-in PLC of the inverter.
RUN/STOP of the built-in PLC can be controlled by turning on/off X15 via CCLink. To perform this control, the external input terminal X5-SD must be
shorted in advance. When the X5 terminal is off, the X15 command is
ignored.
Also note that when the built-in PLC is in a STOP status with Pr. 338
"operation command source" set for CC-Link (setting "0"), X5-SD shorted,
and X15 off, the sequence program will run as soon as Pr. 338 "operation
command source" is switched to external input (setting "1").
<Method 2: Set "1" in Pr. 340 "link start up mode selection".>
1)The parameter setting can be changed using the FR-PU04 (option).
POINT
Switch power on again. After power is restored, the inverter is placed in the
CC-Link operation mode, the "PU" and "EXT" LEDs flicker slowly, and the
operation and start commands using CC-Link communication are made
valid. (The setting is not made valid unless power is switched on again.)
2) Using GX Developer, change the setting of the inverter parameter (Pr. 340). (Refer
to page 131.)
REMARKS
The Pr. 340 setting can also be made using an RS-485 communication user program.

<Setting>
To make communication between the personal computer and inverter, the
communication specifications must be set to the inverter initially. If initial setting is not
made or there is a setting fault, data transfer cannot be made.
* After making the initial setting of the parameters, always reset the inverter. After you
have changed the communication-related parameters, communication cannot be
made until the inverter is reset.

REMARKS
•The inverter station numbers may be set between H00 and H1F (stations 0 and 31) in
hexadecimal.
•*3 indicates the control code.
•*4 indicates the CR or LF code.
When data is transmitted from the computer to the inverter, codes CR (carriage return)
and LF (line feed) are automatically set at the end of a data group on some computers.
In this case, setting must also be made on the inverter according to the computer.
Also, the presence and absence of the CR and LF codes can be selected using Pr. 341.
•At *5, when Pr. 337 "waiting time setting" is other than "9999", create the communication
request data without "waiting time" in the data format. (The number of characters is
decremented by 1.)

8) Error code
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 90.)
REMARKS
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.
(5) Programming instructions
1) When the data from the computer has an error, the inverter will not accept that data.
Hence, always insert a retry program for data error in the user program.
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.

CAUTION
When the inverter's communication check 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 (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.
<Setting items and set data>
After completion of parameter settings, set the instruction codes and data as indicated
below, and then start communication from the computer to allow various types of
operation control and monitoring.

CAUTION
Device test ([Online] - [Debug] - [Device test]) of GX Developer can be performed, but if
devices corresponding to control terminal (e.g. STF, STR) signals are tested, the
devices turn on in the sequence but the inverter does not perform the corresponding
operation.
When you want to operate the inverter actually, refer to 4.10 Debugging Mode
Specifications (page 136).

Prior to Sequence Program Creation
4.2.3
Sequence program execution key
The sequence program execution key (STOP/RUN) of the PLC is switched by turning
off/on the SQ signal.
POINT
SQ-SD must be shorted to execute the built-in PLC function. (Built-in
sequence signal: X5 ON)
CAUTION
If the SQ signal is not turned on, the start signal of the inverter is designed to
become valid by the factory setting of Pr. 507 "inverter operation lock mode setting".
(Refer to page 40.)
Open (STOP) the SQ signal-SD terminals when writing a sequence program, for
example.
When executing the sequence program, short (RUN) the SQ signal-SD terminals.
Remote run/stop of the built-in PLC function can be executed in any of the following
methods:
• Setting using the built-in PLC function parameter (contact)
• Using GX Developer
• Via CC-Link communication (refer to page 143)
REMARKS
•Refer to page 8 for the SQ terminal specifications.
•The validity limit of the SQ terminal can be controlled using Pr. 507 "inverter operation lock
mode setting". (Refer to page 138.)
CAUTION
The outputs (Y) are cleared by turning the SQ signal off (STOP) after sequence
program execution (SQ signal on).
The other devices retain the device data prior to STOP. When you want to clear the
remaining device data, power off or reset (short RES-SD for 0.1s, then open) the
inverter.
100
Prior to Sequence Program Creation
4.2.4
Sequence program write
POINT
Sequence program write can be performed in any operation mode. (Refer to
page 75.)
When rewriting the PLC function parameters and sequence program using GX
Developer, check the following:
1) Check that the sequence program execution key is in the STOP position (signal SQSD is off) (refer to page 100).
2) Check that the inverter is at a stop (RUN indicator is off) (refer to page 42).
3) Check that the communication specification setting parameters (Pr. 332 to Pr. 336)
are set correctly (refer to page 98). If any of these parameters is set incorrectly,
communication with GX Developer cannot be made.
REMARKS
Though the communication specification parameters (Pr. 332 to Pr. 336) are
factory-set to enable communication with GX Developer, use the parameter unit
(FR-PU04) to confirm and/or rewrite them. (Refer to the FR-PU04 instruction
manual for the handling of the FR-PU04.) GX Developer and the FR-PU04 cannot
be connected and used simultaneously.
4) Check the PLC series and sequence program capacity in the GX Developer
parameters (refer to page 98).
5) Refer to the GX Developer manual and write the sequence program.
CAUTION
•A sequence program cannot be written with its steps specified. If written,
the sequence program does not run. (The program outside the specified
range is initialized.)
•Do not read the built-in PLC function parameters and sequence program
without writing them to the inverter once using GX Developer. Since the
inverter does not have normal data, always write the built-in PLC function
parameters and sequence program once.
•Since the built-in PLC function parameters and sequence program are
written to the flash ROM, there are restrictions on the number of write times.
(Approximately 100,000 times)

Function Block Diagram
4.3 Function Block Diagram
How I/O data are transferred to/from the inverter by the built-in PLC function is
explained using function blocks.
(1) I/O data read, write, etc. can be performed by accessing the inverter in the
predetermined method using special relays, special registers, etc.
(2) Operation, parameter read/write, etc. can be performed in accordance with the
created sequence programs (built in the inverter) using input data from the control
input terminals.
With the output signals, output data can be output to outside the inverter from the
control output terminals as not only the inverter's status signals but also pilot lamp
on/off, interlock and other control signals set freely by the user.

REMARKS
When Pr. 79 is other than 0, the mode is fixed.
There are no restrictions on operation mode switching.
On normal completion of operation mode setting, the write completion signal
(X23) turns on, and at the same time, 0 is set to D9150.
If the value written is other than H0000 to H0002 or write is performed during
inverter operation, HFFFF is set to D9150 as soon as the write completion signal
(X23) turns on, resulting in abnormal completion.
If abnormal completion occurs, the operation mode is not changed.

(2) Set frequency (RAM) (D9144)
The D9144 data is written to the RAM as a set frequency. The unit is 0.01Hz.
(For example, 6000 indicates 60.00Hz.)
The range where the frequency can be set is 0 to 12000 (0 to 120.00Hz).
When the frequency setting is written normally, the write completion signal (X24)
turns on, and at the same time, 0 is set to D9150.
If any value outside the range is written, HFFFF is set to D9150 as soon as the
write completion signal (X24) turns on, resulting in abnormal completion. If
abnormal completion occurs, the set frequency is not changed.
POINT
• Although the setting unit is 0.01Hz, the actual operation is performed in
0.1Hz units.
• The frequency can be set in the PU operation mode and CC-Link operation
mode. (Refer to page 75.)
<Set frequency write (RAM) program example>
The following program changes the set frequency (RAM) to 30Hz.

(3) Set frequency (E2PROM) (D9145)
The D9145 data is written to the E2PROM as a set frequency. The unit is 0.01Hz.
(For example, 6000 indicates 60.00Hz.)
The range where the frequency can be set is 0 to 12000 (0 to 120.00Hz).
When the frequency setting is written normally, the write completion signal (X25)
turns on, and at the same time, 0 is set to D9150.
If any value outside the range is written, HFFFF is set to D9150 as soon as the
write completion signal (X25) turns on, resulting in abnormal completion. If
abnormal completion occurs, the set frequency is not changed.
POINT
• Although the setting unit is 0.01Hz, the actual operation is performed in
0.1Hz units.
• Setting is enabled in the PU operation mode and CC-Link operation mode.
(Refer to page 75.)

(4) Alarm definition batch clear (D9146)
Writing H9696 to D9146 batch-clears the alarm definitions.
At completion of clear, the write completion signal (X26) turns on, and at the
same time, 0 is set to D9150. If any value outside the setting range is written or
write is performed during inverter operation, HFFFF is set to D9150 as soon as
the write completion signal (X26) turns on, resulting in abnormal completion.

Description
Name
The inverter parameters can be accessed from the sequence program. X28 to X2B/
Y28 to Y2B are used to perform read/write between the predetermined data registers
(D50 to D93) to read/write parameter values.
Refer to pages 110 and 111 for the accessible parameters and the data registers used
for parameter read/write. (The other parameters are not accessible from the PLC
function. Use the FR-PU04 (option) to access such parameters.)
When parameter read/write processing from the sequence program is not performed,
data registers D50 to D93 can be used freely by the user as general-purpose data
registers.
However, when parameter read/write processing from the sequence program is
performed, D50 to D93 are updated by Y28 to Y2B and their data are overwritten.
Therefore, note this point when using them on the user side.
Actual read/write processing is performed at the END processing of the sequence.
Refer to page 184 for the parameter setting units.
POINT
The inverter must be in the PU or CC-Link operation mode to write the inverter
parameters. (Refer to page 76.)

Writing the inverter parameters
When data are stored into the corresponding registers of the inverter parameters
(refer to page 110) and the parameter write command is turned from off to on, the data
are written to the parameters that are the targets of all device data. (After that, the
write completion is turned on.)
As soon as the inverter parameter write completion (X29 (RAM) or X2B (E2PROM))
turns on, 0 is set to D9150 on normal completion.
If an error occurs during access to the parameters, e.g. if any value outside the setting
range is written or write is performed during inverter operation, the value of parameter
No. + H8000 is set to D9150 as soon as the write completion signal (X29 (RAM) or
X2B (E2PROM)) turns on, resulting in abnormal completion. If abnormal completion
occurs, the parameters are not written. (For example, if an error occurs in the torque
boost, H8000 is written to D9150.)
For whether inverter parameter write can be performed or not, refer to Pr. 77
"parameter write disable selection" (page 74).

CAUTION
1.Since the inverter parameters given on page 110 are all written (batch-written),
start write processing after setting all data to D50-D93. As write cannot be
performed for one parameter, perform parameter read processing once, then
correct only the parameters you want to change, and perform write processing.
2.If write is enabled during inverter operation (Pr. 77=2), write cannot be performed
for Pr. 60 to Pr. 65 and Pr. 505 to Pr. 507 during inverter operation, independently
of the Pr. 77 setting.
If the parameter write command is turned on, data are not written to the above
parameters, resulting in normal completion. Always stop the inverter before
performing parameter write.

User Area Read/Write Method
4.9 User Area Read/Write Method
Inverter parameters Pr. 510 to Pr. 529 can be used as user parameters.
Since this parameter area and the devices used with the PLC function, D100 to D119,
are accessible to each other, the values set in Pr. 510 to Pr. 529 can be used in a
sequence program. The result of operation performed in the sequence program can
also be monitored using Pr. 510 to Pr. 529.

Example of using the user parameter area
When the timing is to be changed for machine adjustment using D100 that
stores the timer setting, setting Pr. 510 without modifying the program enters
the set data into D100, enabling adjustment.
User parameter read/write method
User parameter (Pr. 510 to Pr. 529) and device (D100 to D119) data can be read/
written freely. Data transfer between Pr. 510 to Pr. 529 and D100 to D119 is executed
automatically.
1) User parameter write processing
When values are written to Pr. 510 to P. 529 using the FR-PU04 or computer link
communication, they are written to the parameter storing RAM area and E2PROM
area, and further to D100 to D119 simultaneously.
2) User parameter read processing
When values are written to D100 to D119 from the PLC function side, they are
written to the parameter storing RAM area (Pr. 510 to P. 529) and read using the
FR-PU04 or computer link communication. (Since data are not written to the
E2PROM, making power-on reset returns the data to the original values.)
3) Processing performed at inverter reset or power restoration
When the inverter is reset, the Pr. 510 to Pr. 529 values stored in the E2PROM are
transferred to the RAM area and D100 to D119.

Description
The inverter start signal is made valid regardless of the sequence program
execution key.
The inverter start signal is made valid only when the sequence program
execution key is set to RUN (SQ signal is turned on).
When the sequence program execution key is in the STOP position (SQ
signal is off), the inverter does not start if the inverter start signal STF or STR
is turned on. (If the key is switched from RUN to STOP during inverter
operation, the inverter is decelerated to a stop.)
CAUTION
•Independently of the Pr. 77 setting, this parameter value cannot be rewritten
during inverter operation.
•During automatic operation performed using D9148 in the sequence program,
the inverter comes to a stop when the sequence is set to a STOP status with
"1" set in Pr. 507. However, when "0" is set in Pr. 507, the device data are held
and the operation status does not change if the sequence is set to a STOP
status. (Inverter operation is continued.)
REMARKS
This parameter setting is also valid for the start signal from the operation panel or FRPU04 (option).

Function block diagram
How I/O data are transferred to/from the inverter in CC-Link will be described using
function blocks.
(1) Between the master station and inverter in the CC-Link system, link refresh is
always made at 3.5 to 18ms (512 points).
(2) I/O refresh and master station's sequence program are executed asynchronously.
(3) Data read from the inverter are read from the buffer memory of the CC-Link
system master/local module using the FROM instruction.
(4) Data to be written to the inverter are written to the buffer memory of the CC-Link
system master/local module using the TO instruction.

Output signal
I/O signals assigned to the CC-Link system master/local module. These signals
are used to make communication between the PLC CPU and CC-Link system
master/local module.
Input data from the inverter can be read, and output data from the inverter can be
written. Buffer memory read/write is performed using the FROM/TO instruction of
the sequence program. Refer to page 148 for details of the buffer memory.
PLC link start is commanded from the sequence program. After PLC link has
started, link refresh is always made asynchronously with the sequence program
execution.
I/O data are transferred between the CC-Link system master/local module and
inverter CPU via the sequence program.
I/O data are transferred between the inverter CPU and sequence program. (5)

Errors (Alarms)
6.1 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 the 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; or apply the RES
signal for more than 0.1s. If the RES signal is
Kept on, "Err." appears (flickers) to indicate that
the inverter is being reset.
! When the protective function is activated, take the corresponding corrective action,
then reset the inverter, and resume operation.
CAUTION
At occurrence of an inverter error, the protective function is activated to stop output. At
this time, you can not stop the motor abruptly. Therefore, provide machineries and

!Checking the inverter and converter modules
<Preparation>
(1) Disconnect the external power supply cables (R, S, T) and motor cables (U, V,

(2) Prepare a meter. (Use 100Ω range.)
<Checking method>
Change the polarity of the meter alternately at the inverter terminals R, S, T, U, V, W, P
and N, and check for continuity.
CAUTION
•Before measurement, check that the smoothing capacitor is discharged.
•At the time of discontinuity, the measured value is almost
. Note that
may not be measured when power is momentarily applied due to the influence
of the smothing capacitor. At the time of continuity, the measured value is
several to several ten's-of ohms depending on the module type, circuit tester
type, etc. If all measured values are almost the same, the modules are without
fault.

Precautions for Maintenance and Inspection
(1) Cooling fan
The cooling fan is used to cool heat-generating parts such as the main circuit
semiconductors. The life of the cooling fan bearing is usually 10,000 to 35,000 hours.
Hence, the cooling fan must be replaced 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.
Inverter Model No.
FR-C520-1.5K, 2.2K, 3.7K
Fan type
MMF-06D24DS BKO-C2416H07
! Removal
1) Remove the front cover and wiring
cover. (Refer to page 4)
2) Unplug the fan connector.
The cooling fan is connected with the
cooling fan connector on the side of the
inverter terminal block.
Unplug the connector to disconnect the
inverter and cooling fan.
3) Remove the cooling fan cover.
AIR FLOW
Remove the cover by disengaging the
fixing catches indicated by the arrows.
4) Remove the cooling fan and
cooling fan cover.
The cooling fan is secured by the fixing
catches.
Disengaging
the
fixing
catches
removes the cooling fan and cooling
fan cover.
! Reinstallation
1) After confirming the orientation of
the fan, reinstall the fan so that the
arrow on the left of "AIR FLOW"
faces in the opposite direction of
the fan cover.
CAUTION
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.
172
Precautions for Maintenance and Inspection
(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) Check for external crack, discoloration, fluid leakage, etc.
Judge that the capacitor has reached its life when the measured capacitance of the
capacitor reduced below 85% of the rating.
PROTECTIVE FUNCTIONS
(3) Relays
To prevent a contact fault, etc., relays must be replaced according to the cumulative
number of switching times (switching life).

Measurement of main circuit voltages, currents and
powers
! Measurement of voltages and currents
Since the voltages and currents on the inverter power supply and output sides
include harmonics, accurate measurement depends on the instruments used and
circuits measured.
When instruments for commercial frequency are used for measurement, measure
the following circuits with the instruments given on the next page.

Instructions for Compliance with the European Standards
Appendix 2 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. However, the EMC Directive applies to machines/equipment into which
transistorized inverters have been incorporated, and these machines and
equipment must carry the CE marks. Hence, we prepared the European Standardcompliant noise filters and 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.
When the inverter is connected to a programmable controller (PLC), the
countermeasures taken on the PLC side will be helpful. (Refer to the PLC manual.)
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.

Instructions for Compliance with the European Standards
(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
conform to: EN50178).
2) Compliance
We have self-confirmed our inverters as products compliant to the Low Voltage
Directive and place the CE mark on the inverters.
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.)
* Use the cable sizes on pages 6 under the following conditions.
• Ambient Temperature: 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.
* Use the breaker of type B (breaker which can detect both AC and DC). If not,
provide double or enhanced insulation between the inverter and other equipment,
or put a transformer between the main power supply and inverter.
* Use the inverter under the conditions of overvoltage category II and contamination
level 2 or higher specified in IEC664.
* On the input and output of the inverter, use cables of the type and size set forth in
EN60204 Appendix C.
* The terminals indicated as the control circuit input and output terminals on page 8
are separated safely from the main circuit.

1. General Precaution
The bus capacitor discharge time is 10 minutes. Before starting wiring or inspection,
switch power off, wait for more than 10 minutes, and check for residual voltage
between terminal P (+) and N (-) with a meter etc., to avoid hazard of electrical
shock.
2. Environment
Before installation, check that the environment meets following specifications.

3. Installation
The below types of inverter have been approved as products for use in enclosure
and approval tests were conducted under the following conditions.
Design the enclosure so that the ambient temperature, humidity and ambience of
the inverter will satisfy the above specifications.
Branch circuit protection
For installation in United States, branch circuit protection must be provided, in
accordance with the National Electrical Code and any applicable local codes.
For installation in Canada, branch circuit protection must be provided in accordance
with the Canada Electrical Code and any applicable provincial codes.

5. Wiring of the power supply and motor
For wiring the input (R, S, T) and output (U, V, W) terminals of the inverter, use the
UL-listed copper wires (rated at 75°C) and round crimping terminals. Crimp the
crimping terminals with the crimping tool recommended by the terminal maker.
6. Motor overload protection
These inverters provide solid state motor overload protection.
Set parameter 9 using the following instructions,
(Pr. 9 "electronic thermal O/L relay").
<Setting>
•Set the rated current [A] of the motor.
(Normally set the rated current at 50Hz.)
•Setting "0" makes the electronic overcurrent protection (motor protective function)
invalid. (The inverter's protective function is valid).
•When using a Mitsubishi constant-torque motor, first set "1" in Pr. 71 to choose the
100% continuous torque characteristic in the low-speed range. Then, set the rated
motor current in Pr. 9.
CAUTION
•When two or more motors are connected to the inverter, they cannot be protected by
the electronic overcurrent protection. Install an external thermal relay to each motor.
•When the difference between the inverter and motor capacities is large and the setting
is small, the protective characteristics of the electronic overcurrent protection will be
deteriorated.
In this cause, use an external thermal relay.
•A special motor cannot be protected by the electronic overcurrent protection. Use an
external thermal relay.
