Corrected from:
Inverter Drives 8400 TopLine from firmware version 14.00.00.00
Response of the new version?
When an angular drift error occurs, the reference will only be reset if an error response has been set in C603/3 (everything but "0: No Reaction").
Which products are affected?
Inverter Drives 8400 TopLine with a firmware version lower than 14.00.00.00
What happens?
Unexpected loss of the "Reference known" status.
When does the problem occur?
When an angular drift error occurs (absence of the Z-pulse with a TTL encoder), the "Angular drift error" error message is triggered. The reference is reset as well. This also happens by mistake if the angular drift monitoring function is deactivated via error response = No Reaction.
Short-term measures/recommendations?
None
Evaluation:
Reduction of the machine availability. Response is not necessarily detected during commissioning.
