Fagor alarm 1036: "S" has not been programmed in G95 or in threading
CNC 8055 CNC error · Fagor 8055/8055i
What it means
Feed-per-revolution mode (G95) or electronic threading (G33) was activated without a spindle speed being defined. Since feed and pitch are computed from spindle rpm, the CNC cannot generate motion without S.
Likely causes
- G95/G33 block with F or pitch but no preceding S
- S modal value lost after a reset or gear change
