Fagor alarm 1107: Spindle 2 locked
CNC 8055 CNC error · Fagor 8055/8055i
What it means
Second-spindle version of error 1101: the CNC commanded the sub-spindle drive while its SERVOSON input remained low, so the drive never enabled. The CNC interrupts operation until the readiness chain works again.
Likely causes
- PLC not setting the spindle-2 enable handshake properly
- DWELL(P17) of spindle 2 too short
- auxiliary contactor/relay in the sub-spindle ready circuit failing
Triage note: Twin-spindle lathe models only.
