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.
