Field Circuit Phase Failure Detected; Line Monitoring Undervoltage - Siemens SINAMICS DCM List Manual

r50047[10]: Time of last negative refined zero crossing in phase WU in ms
r50047[11]: Last good 60 ° period in ms
See also: p50089 (Sequence control voltage at power unit wait time), p50095 (Sequence control DC circuit contactor
wait time), p50691 (Sequence control line contactor feedback)
Remedy: - Check threshold for phase failure (p50353).
- Check the field supply voltage.
- Check the fuses and line contactor.

Field circuit phase failure detected

Message value: %1
Message class: Network fault (2)
Drive object: DC_CTRL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: A phase failure has been detected in the field circuit.
The line voltage rms value calculated from the area of each line half-wave (rectifier average value * harmonic factor)
is less than the response value for phase failure monitoring or the distance between two line zero crossings of the
voltage for the field converter is more than 270 degrees.
- Phase failure threshold set incorrectly (p50353)
- Field phase failed
- Line contactor opened in operation
- Fuse blown in field circuit
Fault value (r0949, interpret decimal):
1: Power failure in field infeed
Note:
r50047[1]: Incorrect voltage value as a % of p50078[1]
2: Wait time for new zero crossing has expired in the field phase.
Note:
r50047[1]: Time without zero crossing (= duration 270 °) of armature phase r50047[1] in ms
See also: p50089 (Sequence control voltage at power unit wait time)
Remedy: - Check threshold for phase failure (p50353).
- Check the field supply voltage.
- Check the fuses and line contactor.

Line monitoring undervoltage

Message value: %1
Message class: Network fault (2)
Drive object: DC_CTRL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The line voltage has undershot the permissible undervoltage limit for longer than the setting in p50361.
Fault value (r0949, interpret decimal):
1: Armature undervoltage occurred
2: Field undervoltage occurred
