Fagor alarm 5005: Presence control error detected by the CNC
Fagor CAN/remote I/O error · Fagor 8060/8065/8070
What it means
The 8055 runs a periodic presence handshake with every node on the CAN bus (remote I/O groups, keyboards). Here the CNC concludes that a node has reset itself or is wired incorrectly. Motion stops and the external emergency output activates until communication is restored.
Likely causes
- node dropped off briefly due to 24 V supply dip
- wrong pinout or intermittent CAN cable/connection
- duplicate or wrongly set node ADDRESS selector
