10. Terminal Function Explanation

Terminal Function Explanation

Classi-	Terminal Code	Terminal Name	Explanation of Function
fication
Main	L1, L2	Commercial power supply input	For connection of 1-Phase 220 to 240V commercial power
Circuit		terminals	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	13	Power Supply for Frequency	Used as a power supply for frequency setter (variable
Setting		Setting	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	Common terminal for frequency setting signals 12 and 13
		Terminal
	C1	Frequency Setting	DC4 to 20 mA / 0 to 100% (Input resistance: 250 ohm)
		Current Input (+)
Control	FWD	Forward/Stop Command Input	Forward-direction operation takes place when FWD-CM is
			closed. Drive decelerates and stops when FWD-CM is
Input		Terminal
			opened
	REV	Reverse/Stop Command Input	Reverse-direction operation takes place when REV-CM is
		Terminal	closed. Drive decelerates and stops when REV-CM is opened
	BX	Motor Coast-to-Stop Input	•Drive output is cut off instantly and motor will coast-to-
		Terminal	stop when BX-CM is closed. Alarm signal is not outputted.
			•This functions as multistep frequency selection terminal X2
			when changing function.
			•When THR-CM is opened during operation, drive output is
	THR	External Alarm Input Terminal	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.
