Fagor alarm 2010: Spindle feedback error (2029 = same for spindle 2)
CNC 8055 hardware/feedback error (analog axes) · Fagor 8055/8055i
What it means
No feedback signal reaching the CNC spindle input (A5/A6) - threaded cutting, rigid tapping and M19 orientation become impossible.
Likely causes
- spindle encoder cable damaged or connector loose
- spindle encoder (1000-1250 ppt class) failed
- wrong parameter DIFFBACK(P14)/FBACKAL(P15) masking a real fault
Triage note: Check coupling between encoder and spindle first - slipped or broken dog teeth mimic a dead encoder.
