Fagor alarm 1086: The spindle cannot be homed.
CNC 8055 CNC error · Fagor 8055/8055i
What it means
A spindle home search (M19 homing) was requested but spindle machine parameter REFEED1 (P34) is zero, so the CNC has no reference search speed for the spindle axis and cannot execute homing.
Likely causes
- REFEED1(P34) left at 0 in the spindle parameter table
- spindle parameter table loaded incompletely after a memory reload
Triage note: Configuration fix - set a valid REFEED1 reference feed per the machine's parameter list.
