3.2.2 I/O Signal Connector (CN1) Terminal Layout
The following table shows the terminal layout of I/O signal connectors (CN1).
Note 1. Do not use unused terminals.
2. Connect the shield of the I/O signal cable to the connector shell.
Connect to the FG (frame ground) at the SERVOPACK connector.
3. The functions allocated to the following input and output signals can be changed to /CLT, /VLT, /BK, /WARN or
/NEAR signals by using the parameters. Refer to 3.3.1 Input Signal Allocations and 3.3.2 Output Signal Alloca-
tions.
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)
