Published date: 19 June 2020

Clearing EPF1 on the Altivar ATV61 and ATV71

Product Line:
Altivar Process Drive


Wiring / Programming

A Power Cycle is required. Toggling a bit over communications or a terminal input on the Drive assigned to Fault Reset will not clear EPF1, which means it's a True Safety contact. This is clearly stated in the Programming Manual.
