Fagor alarm 1039: No "F" has been programmed in G94.
CNC 8055 CNC error · Fagor 8055/8055i
What it means
A live-tooling cycle (G60-G63 on driven tools) was started without an active feedrate expressed in mm/min (G94). Driven-tool cycles are feed-controlled in linear units, so the missing modal F makes execution impossible.
Likely causes
- feedrate left in G95 (mm/rev) or undefined before the live-tool cycle
- F modal cleared by reset or by a prior program end
