Fagor alarm 1034: "S" has been programmed, but no gear is active.
CNC 8055 CNC error · Fagor 8055/8055i
What it means
A spindle speed command could not be started because no gear range is selected. After power-up the CNC assumes no gear; when AUTOGEAR(P6)=NO the program must select M41-M44 explicitly before any S command takes effect.
Likely causes
- first S command of the day issued without prior gear-selection M function
- gear M functions stripped out when post-processing the program
