4.2 List of faults and alarms
SINAMICS G130/G150
1522 List Manual (LH2), 07/2016, A5E03263479A
A05053 (F) Parallel circuit: Inadmissible DC link voltage asymmetry
Message value: -
Message class: Application/technological function faulted (17)
Drive object: B_INF, VECTOR_G
Component: Power Module Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The deviation of the DC link voltage measured values exceeds the alarm threshold specified in p7011.
Remedy: - inhibit the pulses of the faulted power unit (p7001).
- check the DC link connecting cables.
- the DC link voltage measurement is incorrect and must be calibrated or renewed.
Reaction upon F: Vector: NONE (OFF1, OFF2, OFF3, STOP2)
Infeed: NONE (OFF1, OFF2)
Acknowl. upon F: IMMEDIATELY
A05054 Parallel circuit: Power unit deactivated
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: B_INF, VECTOR_G
Component: Power Module Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: For the drive object involved, fewer power units connected in parallel are active than exist in the target topology.
Operation is only possible at reduced power (power derating).
Remedy: Re-activate the deactivated power units if required.

F05055 Parallel connection: Power units with illegal code numbers
Message value: Parameter: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: Power Module Propagation: GLOBAL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The code numbers of the power units do not match.
Fault value (r0949, interpret decimal):
Parameter in which the first different power unit code number was detected.
Remedy: Use power units with the same code number.
For parallel circuit configurations, only power units with identical power unit data may be used.
F05055 Parallel connection: Power units with illegal code numbers
Message value: Parameter: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: B_INF
Component: Power Module Propagation: GLOBAL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The code numbers of the power units are not permissible.
For parallel circuit configurations, only power units with identical power unit data may be used.
Possible causes:
- the code numbers of the power units do not match.
For booksize drive units, the following additionally applies:
- a parallel connection is not possible for the power units being used.
- there are too many power units being used in the parallel connection.
