6.3.4 I/O Signal Connector (CN1) Terminal Layout
The following diagram shows the terminal layout and the signals that are preset before shipping.
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.
3. The functions allocated to the following input and output signals can be changed by using the
parameters. Refer to 7.3.2 Input Circuit Signal Allocation and 7.3.3 Output Circuit Signal Allo-
cation.
• 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.
