Fagor alarm 4004: Parameter G00FEED higher at the CNC than at the drive
CNC 8060/8065/8070 SERCOS error · Fagor 8060/8065/8070
What it means
The rapid feedrate G00FEED defined at the CNC exceeds the maximum velocity accepted by the drive for that axis. The check prevents the CNC from commanding speeds the drive would refuse or saturate on.
Likely causes
- G00FEED increased at the CNC after a mechanics change without matching drive limit
- drive maximum-speed parameter lowered (e.g., after motor change)
- mismatched electronic gearing between CNC and drive
