• Use a shield cable that supports an RS-422 signal for the connection to the
IN2 Connector for encoder input, and always connect the Cable shield to
the FG.
• Power source 0 V and COMIN1, COMIN2 (Connector), COMIN2 (Terminal
block), COMOUT1, COMOUT2, COMOUT_F+, COMOUT_F-,
COMOUT2_F+, COMOUT2_F-, and 0VOUT are all isolated.
• COMOUT2_F+ and COMOUT2_F- are the common terminal for dedicated
output for OUT2 Connector 1 through to 4.
