F005 fault in siemens 6RA70 DC Drive
How can resolve problem F005 fault in siemens 6RA70 DC Drive ?
Cause : Fault in the field circuit. The line voltage RMS value calculated from the area of each network half-wave (rectification average value * peak factor) must be greater than the response value for phase failure monitoring.
Possible fault causes
♦ Threshold for phase failure (P353) set incorrectly
♦ Undervoltage / overvoltage threshold (P351, P352) set incorrectly
♦ Field phase failed
