Check: In case this fault happens during field exciter autotuning deactivate the supervision by setting

M1FldOvrCurLev (30.13) = 135
M1FldOvrCurLev (30.13)

 

Parameter settings of group 44 (field excitation: field current controller tuning)

1. Connections of field exciter
2. Insulation of cables and field winding
3. Resistance of field winding

Check field current in parameter group 1

Parameter 1.30 - ..... Actual field current

And check in field terminal using clamp meter , compare both 

 

What is the motor field current value in motor name plate ?
