Fagor alarm 4030: Erroneous numbering of Sercos nodes
CNC 8060/8065/8070 SERCOS error · Fagor 8060/8065/8070
What it means
The address assignment of Sercos nodes (drives plus RCS-S counters) is not consistent, so bus initialization cannot map every physical node to the expected logical ID. Initialization stops until the numbering matches the CNC parameterization.
Likely causes
- duplicate or skipped node selector (DriveID) settings
- RCS-S counter node addressed inconsistently with the CNC table
- node added/removed without revalidating the machine parameters
