Cause : Mains phase loss comes when phase is missing on the supply side, or the mains voltage imbalance is too high. This message also appears for a fault in the input rectifier on the frequency converter. Options are programmed in 14-12 Function at Mains Imbalance.
- Check the supply voltage and supply currents to the frequency converter.
