Explanation of Function
For connection of 3-Phase 200 to 230V commercial power
supply
For connection of a 3-Phase motor
Grounding terminal of drive chassis (case). Be sure to ground
the drive to prevent electric shock or to lower noise
Used as a power supply for frequency setter (variable
resistor: 1 - 5K ohm) (DC + 10V, 10mA max)
DC 0 - +10V / 0 - 100% (Input resistance: 22K ohm)
Common terminal for frequency setting signals 12 and 13
Forward-direction operation takes place when FWD-CM is
closed. Drive decelerates and stops when FWD-CM is
opened
Reverse-direction operation takes place when REV-CM is
closed. Drive decelerates and stops when REV-CM is opened
•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.
•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.
When RST-CM is closed, the drive fault is reset.
