Unable To Achieve Line Synchronization In Transformer Magnetization; Infeed: Current Offset Measurement Interrupted; Infeed: Current Offset Measurement Not Possible - Siemens Sinamics S120 Diagnostic Manual

206502 <location>Infeed: Unable to achieve line synchronization in transformer magnetization
Message value: -
Drive object: AFE_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: Line synchronization is not possible within the monitoring time (p5481[2]).
Remedy: - check the setting of the threshold value (p5485)
- check the setting of the maximum time (p5481[2])
- check the line supply quality.

206601 <location>Infeed: Current offset measurement interrupted
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: Defective current measurement or a DC current is present during the offset measurement.
Alarm value (r2124, interpret decimal):
1: Excessively high phase current has occurred during the current offset calibration.
2: The measured current offset is greater than the 3% of the maximum permissible converter current (e.g. due to a
ground fault in the DC link).
Remedy: Re alarm value = 1:
- possible counter-measure if there is no line contactor: Power up an adequately long time before OFF1 = 1.
Re alarm value = 2:
- defective current measurement or a DC current is present during the offset measurement.
- check the DC link for a ground fault.
206602 <location>Infeed: Current offset measurement not possible
Message value: -
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: After an OFF1 = 1 no valid current offset measurement was able to be made within the monitoring time (p3491) before
closing the line contactor. The current offset is set to 0.
See also: p3491 (Infeed I-offset measurement monitoring time)
Remedy: - check the DC link for a ground fault. A ground fault can destroy parts and components!
- Check the monitoring time setting and if required increase (p3491). At least 100 ms is required for a valid measure-
ment (p3491 > 100 ms).
Notice:
If there is no valid measurement, then under certain circumstances the quality of the DC link control will be reduced.
