Specifications of Options and Peripheral Devices

Specifications of Options and Peripheral Devices

The following options and peripheral devices can be used for the Drive. Select them according to the
application.

* 1. Use a ground fault interrupter with a current sensitivity of 200 mA minimum and an operating time of 0.1 s minimum to prevent operating errors. The interrupter

must be suitable for high-frequency operation.

Example: NV series by Mitsubishi Electric Corporation (manufactured in or after 1988)

EG, SG series by Fuji Electric Co., Ltd. (manufactured in or after 1984)

* 2. The finement zero-phase reactor is manufactured by Hitachi Metals.

Descriptions

Protect Drive wiring

MCCB or Ground
Fault Interrupter



Always connect a breaker to the power supply line to pro-
tect Drive wiring. Use a ground fault interrupter suitable
for high frequencies.

Prevents burning when
a Braking Resistor is
used.

Magnetic Contac-
tor

HI-



Install to prevent the braking resistor from burning out
when one is used. Always attach a surge absorber to the
coil.

Contains switching
surge

Surge Absorber

DCR2-



Absorbs surge from the magnetic contactor and control
relays. Connect surge absorbers to all magnetic contactors
and relays near the Drive.

Isolates I/O signals

Isolator

DGP



Isolates the I/O signals of the Drive and is effective
against inductive noise.

Improve the input
power factor of the
Drive

DC Reactor
AC Reactor

UZDA-



UZBA-



Used to improve the input power factor of the Drive. All
Drives of 18.5 kW or higher contain built-in DC reactors.
These are optional for Drives of 15 kW or less. Install DC
and AC reactors for applications with a large power sup-
ply capacity (600 kVA or higher).

Reduce the affects of
radio and control device
noise

Input Noise Filter

(Single phase) LNFB-



(3 phase) LNFD-



Reduces noise coming into the Drive from the power sup-
ply line and to reduce noise flowing from the Drive into
the power supply line. Connect as close to the Drive as
possible.

Finemet zero-
phase reactor to
reduce radio
noise

F6045GB
(FIL001098)

F11080GB
(FIL001097)

Reduces noise from the line that sneaks into the Drive
input power system. Insert as close to the Drive as possi-
ble.
Can be use on both the input side and output side.

Output Noise Fil-
ter

LF-o

Reduces noise generated by the Drive. Connect as close to
the Drive as possible.

Enable stopping the
machine in a set time
