GE FVR-C9S-2UX Drive Series 10. Terminal Function Explanation

FVR-C9S-2UX

Classi-

fication Terminal Code Terminal Name Explanation of Function

Main

Circuit L1, L2, L3 Commercial power supply input

terminals For connection of 3-Phase 200 to 230V 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

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

C92-03

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