Override Function Is Active [verified] | Fanuc Wn57

Checking if a tool changer will move even if a specific sensor isn't triggered.

A: No. EMG is a hard stop (red alarm). WN57 is a soft warning (white/yellow message).

: In high-end models like the Fanuc 30i/31i/32i Series , an "override mode" for forced I/O allows developers to test machine logic without physical signals. An interesting technical limit is that this mode is typically restricted to three PMC paths simultaneously ; exceeding this triggers an ER47 alarm.

This function is typically used by technicians and builders during machine commissioning or ladder logic debugging to manually force or "override" PMC signals. When active, it can prevent the PMC program from operating normally, which is why the control displays this warning message. Why the WN57 Message Appears
