FaultNameVFD-F SeriesFault DescriptionsCorrective ActionsOver-current duringsteady state operation:1. Short-circuit at motoroutput.2. Sudden increase inmotor loading.3. AC drive outputcapacity is too small.1. Check for possible poor insulation at theoutput line.2. Check for possible motor stall.3. Replace with the AC drive with one thathas a higher output capacity (next HPsize).The external terminalEF-GND goes from OFFto ON.1. When external terminal EF-GND isclosed, the output will be turned off.(Under N.O. E.F.)2. Press RESET after fault has beencleared.Emergency stop.When the multi-functioninput terminals (MI1 to Press RESET after fault has been cleared.MI6) stop, AC drive stopsany output.Internal memory ICcannot be programmed.Internal memory ICcannot be read.1. Return to the factory.2. Check the EEPROM on the controlboard.1. Return to the factory.2. Reset drive to factory defaults.U-phase errorV-phase errorW-phase errorOV or LVReturn to the factory.Return to the factory.Return to the factory.Return to the factory.7-4DELTA ELECTRONICS, INC.
