GX-series EtherCAT Slave Unit User’s Manual

Precautions for Correct Use

• The V1 and V2 terminals as well as the G1 and G2 terminals of the I/O power supply are not

connected internally. Supply power separately for V1-G1 and V2-G2.

• Do not wire NC terminals.

Reference

Wire colors have been changed according to revisions in the JIS standards for photoelectric and

proximity sensors. The colors in parentheses are the wire colors prior to the revisions.
