Armature Circuit Line Voltage Not Ok - Siemens SINAMICS DCM List Manual

F60104 (N, A)

Armature circuit line voltage not OK

Message value: %1
Message class: Network fault (2)
Drive object: DC_CTRL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: On power-up, the time set in p50089 represents the maximum wait time for voltage at the power connections and for
field current in operating states o5 and o4 combined.
On power-up, the time set in p50095 represents the maximum wait time for "Line contactor feedback" in operating
state o3.3 (if activated, see p50691).
This fault is triggered if the above times elapse in one of these operating states.
- Thresholds for the line monitoring incorrectly set (p50078, p50351, p50352, p50353, p50363, p50364).
- Armature voltage not OK (phase failure, undervoltage/overvoltage, underfrequency/overfrequency).
- Line contactor not picking up
- Fuse blown on three-phase side of armature circuit
- Fuse blown in power unit
- Interruption affecting thyristor firing pulse cable (auxiliary cathodes at connections X12, X14, X16 are used for
voltage transmission).
Fault value (r0949, interpret decimal):
2: Wait time set in p50089 has expired in operating state o4.0.
3: Fuse blown on three-phase side of armature circuit
6: Wait time set in p50095 has expired in operating state o3.3.
Note for fault value = 2:

Remedy: - Check the thresholds for the line monitoring (p50078, p50351, p50352, p50353, p50363, p50364).
- Check line voltage and line contactor.
- Check fuses for armature circuit.
- Check thyristor firing pulse cable (X12, X14, X16).
