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.
