8) General instructions
zDo not fit capacitive equipment such as power factor correction capacitor, surge suppressor or radio noise filter (option FR-BIF) to
the inverter output side.
zThe connection orientation of the output cables (terminals U, V, W) to the motor will affect the direction of rotation of the motor.
zCheck all parameters, and ensure that the machine will not be damaged by a sudden start-up.
zWhen you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.
zSince the [STOP] key is valid only when functions are set (refer to page 62) provide a circuit and switch separately to make an
emergency stop (power off, mechanical brake operation for emergency stop, etc).
zMake sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart the motor suddenly.
zThe load used should be a three-phase induction motor only. Connection of any other electrical equipment to the inverter output may
damage the equipment.
zDo not modify the equipment.
zDo not perform parts removal which is not instructed in this manual. Doing so may lead to fault or damage of the inverter.
zThe electronic thermal relay function does not guarantee protection of the motor from overheating.
zDo not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.
zUse a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic equipment may be affected.
zTake measures to suppress harmonics. Otherwise power supply harmonics from the inverter may heat/damage the power capacitor
and generator.
zWhen a 400V class motor is inverter-driven, please use an insulation-enhanced motor or measures taken to suppress surge
voltages. Surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the
motor.
zWhen parameter clear or all clear is performed, each parameter returns to the factory setting. Each parameter returns to the factory
setting.
zThe inverter can be easily set for high-speed operation. Before changing its setting, fully examine the performances of the motor and machine.
zIn addition to the inverter's holding function, install a holding device to ensure safety.
zBefore running an inverter which had been stored for a long period, always perform inspection and test operation. In addition to the
inverter's holding function, install a holding device to ensure safety.
zProvide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if
the inverter fails.
zWhen the breaker on the inverter input side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter, etc.
Identify the cause of the trip, then remove the cause and power on the breaker.
zWhen the protective function is activated, take the appropriate corrective action, then reset the inverter, and resume operation.
zDo not carry out a megger (insulation resistance) test on the control circuit of the inverter.
zTreat as industrial waste.

Basic configuration and connection
of peripheral devices
1.1 Basic configuration and connection of peripheral devices
1.1.1 Basic configuration
Power supply
Use within the permissible power supply specifications of the inverter. (Refer to page 103.)
Moulded case circuit breaker (MCCB) or earth leakage circuit breaker (ELB)
The breaker must be selected carefully since an in-rush current flows in the inverter at power-on.
(Refer to page 3.)
Magnetic contactor
Install the magnetic contactor to ensure safety. (For details, refer to the Instruction Manual (detailed).)
Do not use this magnetic contactor to start and stop the inverter. Doing so will cause the inverter life to
be shorten. (Refer to page 3.)
Power factor improving reactor
A reactor (option) should be used when the power factor is to be improved or when the inverter is
installed near a large power supply system (1000kVA or more and wiring distance is within 10m). The
inverter may be damaged if you do not use reactors.
Make selection carefully. (Refer to page 3.)
• DC reactor (FR-HEL/BEL), AC reactor (FR-HAL/BAL)
(Caution) Remove the jumpers across terminals P-P1 to connect to the DC reactor.
Noise filter
Install a noise filter to reduce the electromagnetic noise generated from the inverter.
• Line noise filter (FR-BSF01) (FR-BLF)
Effective in the range from about 1MHz to 10MHz. When more wires are passed through, a more
effective result can be obtained. (Note that the number of wires run through is limited when fitting to
the output side.)
• Radio noise filter (FR-BIF)
Effective in reducing the noises in the AM radio frequency band. Dedicated filter for the input side.
Brake resistor
(Caution) • Remove the jumpers across terminals PR-PX to connect to the inverter.
• Set "1" in Pr. 30 "regenerative function selection".
• Set Pr. 70 "special regenerative brake duty" as follows:
7.5K or less . . . . 10%
11K or more . . . 6%
Brake unit
(Caution) Remove the jumpers across terminals PR-PX to connect to the inverter.
Power regeneration common converter (FR-CV)
(Caution) • Remove the jumpers across terminals R-R1 and S-S1.
• For a terminal to be connected to the RDYB signal of the FR-CV, set "10" (X10 signal) in
any of Pr. 180 to Pr. 183 and Pr. 187(input terminal function selection).
• Set "2" in Pr. 30 "regenerative function selection".
• Select the converter one rank higher in capacity than the inverter.
Selection example: FR-V520-7.5K→FR-CV-11K, FR-V520-15K→FR-CV-18.5K (When
connecting two inverters to one FR-CV, the capacity is 11K + 18.5K = 29.5K. Therefore,
select FR-CV-30K.)
Motor
zDedicated motor (Refer to page 103.)
This is a highly environmentally-resistant motor based on a totally-enclosed squirrel-cage induction
motor designed for the vector inverter. Select the motor that matches the inverter capacity.
Encoder
For the encoder dedicated motor, refer to page 12.
Devices connected to the output
Do not install a power factor correction capacitor, surge suppressor or radio noise filter (FR-BIF
option) on the output side of the inverter.
When installing a moulded case circuit breaker on the output side of the inverter, contact each
manufacturer for selection of the moulded case circuit breaker.
Earth (Ground)
To prevent an electric shock, always earth (ground) the motor and inverter. For reduction of induction
noise from the power line of the inverter, it is recommended to wire the earth (ground) cable by
returning it to the earth (ground) terminal of the inverter.
( For details of noise reduction techniques, refer to the Instruction Manual (detailed).)
CAUTION
• Do not fit capacitive equipment such as power factor correction capacitor, radio noise filter (FR-BIF option) or surge
suppressor to 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 connected, immediately remove them. (If the FR-BIF radio noise filter is
connected, switching power off during motor operation may result in "E.UVT". In this case, connect the radio noise filter
on the primary side of the magnetic contactor.)
• Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the
communication devices (such as AM radios) used near the inverter. In this case, install the FR-BIF optional radio noise
filter (for use on the input side only) or FR-BSF01 or FR-BLF line noise filter to minimize interference.
• For details of peripheral devices, refer to manuals of each option and peripheral devices.

(3) Cables and wiring length
Select the recommended cable size to ensure that a voltage drop will be 2% max.
If the wiring distance between the inverter and motor is long, the motor torque will decrease due to the voltage drop of the
main circuit cable especially at high-frequency output. The encoder signal will also be affected by the voltage drop.
The following selection example assumes the wiring length of 20m.
200V class (When input power supply is 220V)
400V class (When input power supply is 440V)
The line voltage drop can be calculated by the following formula:
Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop
(torque reduction) in the low speed range.
(4) Wiring length
zThe wiring length should be 100m maximum. (during vector control)

CAUTION
• Tighten the terminal screw to the specified torque.
A screw that has been tighten too loosely can cause a short circuit or malfunction.
A screw that has been tighten too tightly can cause a short circuit or malfunction due to the unit breakage.
• The crimping terminals recommended for use to wire the power supply and motor are those provided
with insulation sleeves.
CAUTION
• Especially for long-distance wiring, the inverter may be affected by a charging current caused by the
stray capacitances of the wiring, leading to a malfunction of the overcurrent protective function or a
malfunction or fault of the equipment connected on the secondary side. If fast response current limit
malfunctions when fast response current limit function is made valid, disable fast response current
limit. (Refer to Pr.156 "stall prevention operation selection".)

(3) Wiring instructions
1) Terminals 5, SD and SE are common to the I/O signals and isolated from each other. Do not earth (ground)
these terminals. Avoid connecting the terminal SD and 5 and the terminal SE and 5.
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) Since the control circuit input signals are micro currents, 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 0.75mm2gauge for connection to the control circuit terminals. If the
cable gauge used is 1.25mm2or more, the front cover may be lifted when there are many cables running or the
cables are run improperly, resulting in an control panel or parameter unit contact fault.

(4) Connecting the control circuit to a power supply separately from the main circuit
If the magnetic contactor (MC) in the inverter power supply is opened when the protective circuit is operated, the
inverter control circuit power is lost and the alarm output signal cannot be kept on. To keep the alarm signal on
terminals R1 and S1 are available. In this case, connect the power supply terminals R1 and S1 of the control circuit
to the primary side of the MC.

<Connection procedure>
•Model FR-V520-3.7K to 55K, FR-V540-3.7K to 55K
<Connection procedure>
CAUTION
1. When the main circuit power (R, S, T) is on, do not switch off the control power (terminals R1, S1).
Otherwise the inverter may be damaged.
2. When using a separate power supply, the jumpers across R-R1 and S-S1 must be removed. Otherwise
the inverter may be damaged.
3. For a different power supply system, which takes the power of the control circuit from other than the
primary side of the MC, the voltage should be equal to the main circuit voltage.
4. For the FR-V520-3.7K to 55K, FR-V540-3.7K to 55K, the power supply cables must not be connected
to the lower terminals. If connected, the inverter may be damaged.
5. Supplying power to only the R1 and S1 terminals and entering the start signal will result in an error
indication (E.OC1).

(5) Changing the control logic
The input signals are factory set to sink logic (SINK).
To change the control logic, the jumper connector on the back of the control circuit terminal block must be moved to
the other position.
(The output signals may be used in either the sink or source logic independently of the jumper connector position.)
1) Loosen the two mounting screws in both ends of the control circuit terminal block. (The screws cannot be
removed.) Pull down the terminal block from the back of the control circuit terminals.
2) Fit the jumper connector from the sink logic (SINK) position on the back surface of the control circuit terminal
block to the source logic (SOURCE) position to change to the source logic.
3) Using care not to bend the pins of the inverter's control circuit connector, reinstall the control circuit terminal
block and fix it with the mounting screws.
CAUTION
1. Make sure that the control circuit connector is fitted correctly.
2. While power is on, never disconnect the control circuit terminal block.
3. The sink-source logic change-over jumper connector must be fitted in only one of those positions. If
it is fitted in both positions at the same time, the inverter may be damaged.
