Fagor alarm 1101: Spindle 1 locked
CNC 8055 CNC error · Fagor 8055/8055i
What it means
The CNC issued a velocity/output command to the spindle drive while the spindle SERVOSON enable input was still low. The drive therefore never becomes ready and the CNC flags the spindle as locked; motion and enables are shut down as with other servo-side errors.
Likely causes
- PLC ladder not handling the SERVOSON signal correctly
- spindle parameter DWELL(P17) too short for the drive's ready delay
- drive ready relay/contact not closing (wiring or auxiliary supply issue)
Triage note: Error 1107 is the equivalent for spindle 2.
