Field current monitoring fault in field circuit

Message value: %1
Message class: Network fault (2)
Drive object: DC_CTRL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: Field current monitoring has detected erroneous behavior.
- Field phase failed
- Line contactor not picking up
- Fuse blown in field circuit
- Field current controller and/or field current controller pre-control not optimized or optimization is very poor.
Fault value (r0949, interpret decimal):
1: The field current actual value was smaller than the percentage of the field current setpoint set in p50396.
2: The field line voltage was not available within the time set in p50089.
3: The field current was not available within the time set in p50089.
4: The external field current monitoring has responded (BI: p50265 = 1/0 signal).
Note for fault value = 1:
r50047[1]: Setpoint at field current controller input (r52268)
r50047[2]: Actual value at field current controller input (r52265)
r50047[3]: External monitoring (p50265)
r50047[4]: Operating mode (p50082)
r50047[5]: Threshold for monitoring (p50396)
Note for fault value = 2:
- r50047[1]: line state (r53145).

monitoring setpoint factor), p50397 (Field current monitoring fault delay time), r52265 (Cl-loop field curr ctrl current
controller actual value), r52268 (Closed-loop field current control current controller setpoint)
Remedy: - Check field phases.
- Check line contactor.
- Check fuses in field current circuit.
- Perform an optimization run for the field current controller (p50051 = 24).
- Check the threshold and time for field current monitoring (p50396, p50397).

Short-circuit voltage Uk too high

Message value: %1
Message class: General drive fault (19)
Drive object: DC_CTRL
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: The per unit short-circuit voltage of the line supply is greater than 10 %.
Permissible values are between 2 and 10 %.
See also: r50073 (Device rated direct current field), p50082 (Field power unit operating mode), p50396 (Field current
monitoring setpoint factor), p50397 (Field current monitoring fault delay time), r52265 (Cl-loop field curr ctrl current
controller actual value), r52268 (Closed-loop field current control current controller setpoint)
Remedy: Check the dimensioning of the commutating reactors or the line transformer.
