4 Faults and alarms
4.2 List of faults and alarms
SINAMICS DCM
1146 List Manual (LH8), 02/2015, 6RX1800-0ED76
Remedy: - Check the threshold for triggering the alarm (p50491).
- Reduce the motor load if necessary.
- Check the ambient temperature and reduce if necessary.
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY
Reaction upon N: NONE
Acknowl. upon N: NONE
F60035 (N, A) Motor blocked
Message value: -
Message class: Motor overload (8)
Drive object: DC_CTRL
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: The fault is triggered if the following conditions prevail for longer than the time set in p50355:
- The positive or negative armature current or torque limit has been reached
- Armature current r52109 > 1.0%
- Speed actual value r52166 < p50356
Note:
r50047[1]: Stall protection monitoring time p50355
r50047[2]: Speed threshold p50356
r50047[3]: Armature current r52109
r50047[4]: Speed actual value r52166
r50047[5]: Torque limit r53150
r50047[6]: Armature current limits r53151
See also: p50355 (Stall protection monitoring time)
Remedy: - Reduce the motor load.
- Increase the current or torque limit.
- Check and if necessary increase the monitoring threshold.

F60036 (N, A) Armature circuit/field circuit interrupted
Message value: %1
Message class: General drive fault (19)
Drive object: DC_CTRL
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: The firing angle is at the rectifier stability limit for more than 500 ms and the current is less than 1% of the rated DC
current.
Fault value (r0949, interpret decimal):
1: Armature circuit
2: Field circuit
Remedy: - Armature circuit or field circuit interrupted.
- Rectifier stability limit Alpha-G incorrectly set (p50150, p50250).
- Drive operates at the Alpha-G limit (e.g. due to a line undervoltage condition).
- EMF too high, because the maximum speed has been set too high.
- EMF too high, because field weakening was not activated.
- EMF too high, because the field current was set too high.
