E.PuCH fault in KEB COMBIVERT R6 Drive indicates the power unit has changed. This means the drive detected a different voltage class on the line supply since the last power-up and requires manual parameter confirmation.
Cause:
The voltage class of the line supply has changed since last power on and must be confirmed (cycling power will not clear).
Remedy:
Re-enter the value in CP.31 to clear the fault. The value displayed cannot be changed and is an arbitrary ID number and NOT a voltage setting.
