Optimization Run Limit Value Violated - Siemens SINAMICS DCM List Manual

4 Faults and alarms
4.2 List of faults and alarms
Note for fault value = 704:
- r50047[1]: Rated supply voltage [V]
- r50047[2]: CCP rated supply voltage [V]
- r50047[3]: Line voltage tolerance DCM (1 = 100 %)
- r50047[4]: Line voltage tolerance CCP (1 = 100 %)
Note for fault value = 707:
- r50047[1]: Calculated pre-charging voltage [V]
- r50047[2]: Possible maximum value of the pre-charging voltage [V]
Note for fault value = 708:
- r50047[1]: Calculated chopper energy in the armature circuit [J]
- r50047[2]: CCP chopper energy [J]
Remedy: For fault value = 101:
Check field circuit for interruption (e.g. due to blown fuse).
For fault value = 201:
Check armature circuit for interruption (e.g. due to blown fuse).
For fault value = 207:
Temporarily reduce the rated motor current (p50100) so that the rated motor current is significantly less than the
device rated current (e.g. p50100 = 50 % of r50072[1]).
For fault value = 401:
Check the setting of p50078[0], p50100, p50101 and p50110.
For fault value = 402:
Check the optimization of the field circuit.
For fault value = 403:
Check the optimization of the speed controller.
Check the setting of the acceleration times.
Check the setting of the current and torque limits.
For fault value = 404:
Check the polarity of speed actual value sensing (incremental encoder TTL/HTL, analog tachometer).
For fault value = 405:
Check the minimum motor excitation current (p50103).
For fault value = 407:
Check the torque limiting settings.
For fault value = 408:
Check the armature current limiting settings.
For fault value = 409:
Reduce the mechanical load.
For fault value = 701:
Check the setting of p50790 (value = 6).
For fault value = 704:
Check the setting of p50078[0].
For fault value = 706:
Check the optimization of the armature circuit.

F60051 (N, A)

Optimization run limit value violated

Message value: %1
Message class: Hardware/software error (1)
Drive object: DC_CTRL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: During the optimization run, an attempt was made to set a parameter to a value outside its valid range of values.
The parameter value was set to the appropriate limit value.
