Warning Output; Feedback Output - Omron SMARTSTEP 2 SERIES User Manual

Brake Interlock Output
Pin 11: Brake Interlock Output (BKIR)
Function
The external brake timing signal is output.
This output is turned ON to release the external brake.

Warning Output

Pin 12: Warning Output (WARN)
Function
Pin 12 outputs the warning signal selected in the Warning Output Selection (Pn09).

Feedback Output

Pin 15: Encoder Phase A+ Output (+A)
