Fagor alarm 3755: Machine parameter PLOOPRESOL incompatible with drive version
CNC 8060/8065/8070 servo/feedback error · Fagor 8060/8065/8070
What it means
The position-loop resolution selected with PLOOPRESOL requires a minimum drive software version, and the connected drive is older than that. The configuration is rejected because the older firmware cannot deliver feedback at the requested resolution.
Likely causes
- PLOOPRESOL raised after retrofit without upgrading drive firmware
- mixed drive generations on the same machine
- drive replaced by a unit carrying outdated software
