* 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.

Model (Code)

Always connect a breaker to the power supply line to pro-

tect Drive wiring. Use a ground fault interrupter suitable

for high frequencies.

Install to prevent the braking resistor from burning out

HI- J

when one is used. Always attach a surge absorber to the

coil.

Absorbs surge from the magnetic contactor and control

DCR2-

relays. Connect surge absorbers to all magnetic contactors

and relays near the Drive.

Isolates the I/O signals of the Drive and is effective

DGP

against inductive noise.

Used to improve the input power factor of the Drive. All

Drives of 18.5 kW or higher contain built-in DC reactors.

UZDA-

These are optional for Drives of 15 kW or less. Install DC

UZBA-

and AC reactors for applications with a large power sup-

ply capacity (600 kVA or higher).

Reduces noise coming into the Drive from the power sup-

(Single phase) LNFB-

ply line and to reduce noise flowing from the Drive into

(3 phase) LNFD- HF

the power supply line. Connect as close to the Drive as

possible.

F6045GB

Reduces noise from the line that sneaks into the Drive

(FIL001098)

input power system. Insert as close to the Drive as possi-

ble.

F11080GB

Can be use on both the input side and output side.

(FIL001097)

Reduces noise generated by the Drive. Connect as close to

LF-o

the Drive as possible.

ERF-150WJ

Consumes the regenerative motor energy with a resistor to

(R00

)

reduce deceleration time (use rate: 3% ED).

LKEB-

Consumes the regenerative motor energy with a resistor to

(75600-K

reduce deceleration time (use rate: 10% ED).

CDBR-

Used with a Braking Resistor Unit to reduce the decelera-

(72600-R

tion time of the motor.

Allows frequency reference settings and ON/OFF opera-

JVOP-95•

tion control to be performed by analog references from a

(73041-0905X- )

remote location (50 m max.).

Frequency counter specifications: 60/120 Hz, 90/180Hz

Allows frequency reference settings and ON/OFF opera-

JVOP-96•

tion control to be performed by analog references from a

(73041-0906X- )

remote location (50 m max.).

Frequency counter specifications: 75 Hz, 150 Hz, 220 Hz

1 m cable: (72606-

WV001)

Extension cable to use a Digital Operator remotely.

3 m cable: (72606-

Cable length: 1 m or 3 m

WV003)

A system controller that can be match to the automatic

JGSM-

control system to produce an optimum system configura-

tion.

Handles momentary power losses for the control power

P00 0

supply for models 2.2 kW or less (maintains power for

(73600-P00 0)

2 s).

DCF-6A

RV30YN20S (2 kΩ)

Devices to set or monitor frequencies externally.

CM-3S

Measures the output voltage externally and designed for

SCF-12NH

use with a PWM Drive.

2 kΩ (ETX003270)

Connected to the control circuit terminals to input a fre-

20 kΩ (ETX003120)

quency reference.

(RH000850)

Calibrates the scale of frequency meters and ammeters.
