Fagor alarm 1209-1217: * axis servo error
CNC 8055 CNC error · Fagor 8055/8055i
What it means
Speed-tracking watchdog: after the time set by FBALTIME (P12), the real axis velocity stayed below 50% or above 200% of the commanded feed. The CNC treats it as a servo failure - full stop, enables removed, analog outputs canceled, external emergency relay activated and program interrupted.
Likely causes
- drive unable to develop torque (faulty power stage, missing bus voltage)
- motor power cable loose or damaged
- mechanical stall/crash loading the axis beyond its capability
- feedback dropout corrupting the measured velocity
- FBALTIME window too aggressive for the application
Triage note: Nine-code axis-mapped range (1209 = first axis).
