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.
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.
Inverter
The life of the inverter is influenced by ambient temperature. The ambient temperature should be
as low as possible within the permissible range. This must be noted especially when the inverter
is installed in an enclosure. (Refer to page 6.)
Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away
from the main circuit to protect them from noise. (Refer to page 7.)
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
Dedicated 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).)
