2.4.2 List of CN1 Terminals
The following diagram shows the layout and specifications of CN1 terminals.
„ CN1 Terminal Layout
Note: 1. Do not use unused terminals for relays.
2. Connect the shield of the I/O signal cable to the connector shell. Connect to the FG (frame
ground) at the SERVOPACK-end connector.
