Line Monitoring Overvoltage; Line Frequency Less Than Minimum Line Frequency - Siemens SINAMICS DCM List Manual

4 Faults and alarms
4.2 List of faults and alarms
Note:
r50047[1] = 0: Undervoltage in armature phase UV
r50047[1] = 1: Undervoltage in armature phase VW
r50047[1] = 2: Undervoltage in armature phase WU
r50047[1] = 3: Undervoltage in field phase
r50047[2] = Incorrect voltage value as a % of p50078[0] or p50078[1]
Remedy: - Check monitoring limit for armature (p50078[0] * (1 + p50351/100%)).
- Check monitoring limit for field (p50078[1] * (1 + p50351/100%)).
- Check monitoring time (p50361).

F60007 (N, A)

Line monitoring overvoltage

Message value: %1
Message class: Network fault (2)
Drive object: DC_CTRL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The line voltage has overshot the permissible overvoltage limit for longer than the setting in p50362.
Fault value (r0949, interpret decimal):
1: Armature overvoltage occurred
2: Field overvoltage occurred
Note:
r50047[1] = 0: Overvoltage in armature phase UV
r50047[1] = 1: Overvoltage in armature phase VW
r50047[1] = 2: Overvoltage in armature phase WU
r50047[1] = 3: Overvoltage in field phase
r50047[2] = Incorrect voltage value as a % of p50078[0] or p50078[1]
Remedy: - Check monitoring limit for armature (p50078[0] * (1 + p50352/100%)).
- Check monitoring limit for field (p50078[1] * (1 + p50352/100%)).
- Check monitoring time (p50362).

F60008 (N, A)

Line frequency less than minimum line frequency

Message value: %1
Message class: Network fault (2)
Drive object: DC_CTRL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The line frequency has undershot the set threshold for monitoring of the minimum line frequency for more than 40
ms.
Fault value (r0949, interpret decimal):
1: Armature supply frequency less than minimum line frequency
2: Field supply frequency less than minimum line frequency
Note:
r50047[1]: Incorrect frequency value in Hz
