Fagor alarm 1102: Following error of spindle 1 out of limit
CNC 8055 CNC error · Fagor 8055/8055i
What it means
With the spindle closed in position loop (M19 oriented), the difference between commanded and actual spindle position exceeded spindle parameters MAXFLWE1(P21)/MAXFLWE2(P22). The CNC stops everything, cancels enables/analog outputs, opens the position loop if applicable, and additionally activates the external emergency relay output.
Likely causes
- spindle drive fault or missing enable/power supply
- defective spindle encoder feedback or feedback cable
- velocity command cable broken (no +/-10V reaching drive)
- mechanical overload - spindle binding or stiff
- gain/limits tuned wrongly or defective CNC output stage
Triage note: Error 1108 reports the same fault for spindle 2. Systematic cause groups per Fagor: drive, motor/power cabling, feedback, mechanics, CNC/parameters.
