Fagor alarm 1073: Motion block with zero speed.
CNC 8055 CNC error · Fagor 8055/8055i
What it means
An F0 feedrate appeared in a motion block while general machine parameter FEEDTYPE (P170) is not 0. With FEEDTYPE other than zero, zero feed is not permitted, so the CNC stops instead of moving at an indeterminate rate.
Likely causes
- F0 programmed literally in the part program
- variable-based F assignment evaluated to 0
- FEEDTYPE changed by parameter edit without reviewing old programs
Triage note: Either restore FEEDTYPE(P170)=0 or program a nonzero F.
