3.4.2 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 the shield to the FG (frame ground) at the servo amplifier-end connector shell only.
