Check:
- M1FldMinTrip (30.12) , FldMinTripDly (45.18)
- parameter settings of group 44 (fieldexcitation: field current controller tuning, EMF controller tuning, flux linearization)
- motor name plate for minimum current at maximum field weakening (maximum speed)
- field circuit fuses
- field contactor is not closed
- if the field current oscillates
- if the motor is not compensated and has a high armature reaction
- fault message at field exciter (7-segment display or flashing LED’s)
