Fagor alarm 4215: Error in the Sercos ring (MDT reception)
CNC 8060/8065/8070 SERCOS error · Fagor 8060/8065/8070
What it means
A slave failed to receive the master data telegram (MDT) correctly, ending synchronized operation. On Sercos III-equipped systems this mirrors a reception-path disturbance rather than a drive-internal fault.
Likely causes
- connection problem along the reception path
- parameterization inconsistency between nodes
- degraded Sercos board optics
