6.2. Layout and Specifications of Connectors of Control Circuit
■ Layout of connectors of control circuit
The control circuit connectors are arranged on the drive front.
The G5 series does not support the RS-232 communications and Parameter Unit functions of the SS2 series.
For the G5 series, parameters can be set from CX-Drive (computer tool) via USB communications.
■ Control I/O connector
● Pulse input
Input the command pulse of for position control.
