Issue:
Clearing EPF1 on the Altivar ATV61 and ATV71

Product Line:
ATV61
ATV71

Environment:
ALL

Cause:
Wiring / Programming

Resolution:
EPF1 indicates an external device has triggered the drive to trip.


This is normally an external signal connected to a logic input on the drive and programmed in Menu 1.8: Fault Management.

A Power Cycle is required to reset the error, once the correct signal is restored.
Commanding a Fault reset via the logic inputs, the keypad, or over serial communication will not clear EPF1.
