6.3.2 I/O Signal Connector (CN1) Terminal Layout
The following diagram shows the terminal layout and the signals that are preset before shipping.
Notes: 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.
3. The functions allocated to the following input and output signals can be changed by using the
parameters.
• Input signals: /S-ON, /P-CON, P-OT, N-OT, /ALM-RST, /P-CL, and /N-CL
• Output signals: /TGON, /S-RDY, and /V-CMP (/COIN)
• The above output signals can be changed to /CLT, /VLT, /BK, /WARN, and /NEAR.
