F515 M1FexOverCur Motor 1 field exciter overcurrent Fault In ABB DCS800
How can resolve problem F515 M1FexOverCur Motor 1 field exciter over current Fault In ABB DCS800 ?
Check: In case this fault happens during field exciter autotuning deactivate the supervision by setting
M1FldOvrCurLev (30.13) = 135
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
What is condition of fault means when fault comes after run command or coming continuously?
Check motor data in group 99 and autotune motor field and armature.
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 ?
