Chapter 3 Connections and WiringASDA-B Series

NOTE

1)GND (Pin 8) and COM- (Pin 13) of CN1 connector are independent respectively and do not have connection with the ground terminal outside the servo drive.

3.3.2 Signals Explanation of Connector CN1

The Tables 3.A, 3.B, & 3.C detail the three groups of signals of the CN1 interface. Table 3.A details the general signals. Table 3.B details the Digital Output (DO) signals and Table 3.C details the Digital Input (DI) signals. The General Signals are set by the factory and can not be changed, reprogrammed or adjusted. Both the Digital Input and Digital Output signals can be programmed by the users.
