fication

Terminal Code

Terminal Name

Explanation of Function

Main

Circuit

L1, L2

Commercial power supply input
terminals

For connection of 1-Phase 220 to 240V commercial power
supply

U, V, W

Drive Output Terminals

For connection of a 3-Phase motor

E (G)

Drive Grounding Terminals

Grounding terminal of drive chassis (case). Be sure to ground
the drive to prevent electric shock or to lower noise

Frequency

Setting

13

Power Supply for Frequency
Setting

Used as a power supply for frequency setter (variable
resistor: 1 - 5K ohm) (DC + 10V, 10mA max)

12

Frequency Setting Voltage Input

DC 0 - +10V / 0 - 100% (Input resistance: 22K ohm)

11*

Frequency Setting Common
Terminal

Common terminal for frequency setting signals 12 and 13

C1

Frequency Setting
Current Input (+)

DC4 to 20 mA / 0 to 100% (Input resistance: 250 ohm)

Control

Input

FWD

Forward/Stop Command Input
Terminal

Forward-direction operation takes place when FWD-CM is
closed. Drive decelerates and stops when FWD-CM is
opened

REV

Reverse/Stop Command Input
Terminal

Reverse-direction operation takes place when REV-CM is
closed. Drive decelerates and stops when REV-CM is opened

BX

Motor Coast-to-Stop Input
Terminal

•Drive output is cut off instantly and motor will coast-to-
stop when BX-CM is closed. Alarm signal is not outputted.

•This functions as multistep frequency selection terminal X2
when changing function.

THR

External Alarm Input Terminal

•When THR-CM is opened during operation, drive output is
cut (motor will coast-to-stop) and an alarm signal is
outputted. This signal is latched and reset by RST input.

•This functions as multistep frequency selection terminal X1
when changing functions.

RST

Alarm Reset Terminal

When RST-CM is closed, the drive fault is reset.

CM*

Control Input Common Terminal

Common terminal for control input signals

C92-7-03

* Electric potential of 11 terminal is identical with that of CM terminal.
