Fagor alarm 1146-1154: * axis locked
CNC 8055 CNC error · Fagor 8055/8055i
What it means
The CNC issued the motion command to the affected axis drive while the axis SERVO(n)ON enable input was still low - the same lockout condition as alarm 1101 but for a linear axis. Motion stops, enables are removed and analog outputs canceled; detection from the position loop opens the loop (LOPEN=1) and aborts the channel program.
Likely causes
- PLC ladder mishandling the axis-ready/SERVO(n)ON handshake
- axis parameter DWELL(P17) shorter than the drive ready time
- loose enable wiring between PLC output and drive input
- drive fault keeping READY from asserting
Triage note: Nine-code axis-mapped range (1146 = first axis).
