Cause : Failure of electronics power supply comes when failure of the electronics supply voltage (terminals 5U1, 5W1, 5N1) in “RUN” state for longer than the “restart” time set in parameter P086 or the electronics are operating on undervoltage.
Possible fault causes:
♦ Line contactor has opened in “RUN” state
♦ Brief supply failure
♦ Supply voltage too low
