Fagor alarm 4016: The drive is not a Fagor drive. Software option not allowed
CNC 8060/8065/8070 SERCOS error · Fagor 8060/8065/8070
What it means
Ring initialization detected a third-party (non-Fagor) SERCOS slave while the CNC option for non-Fagor digital servos is not activated. Fagor gates third-party drive support behind a licensed option, so the node is refused.
Likely causes
- third-party SERCOS drive added without purchasing/activating the option
- option license lost after CNC software reload
- non-Fagor node left connected unintentionally
