Fagor alarm 2043: Parameters of the frequency filter set wrong.
CNC 8055 servo error · Fagor 8055/8055i
What it means
One or more values of the FAGOR frequency-filter parameter set are invalid, so the filters would remain inactive if execution continued. Detected at power-up or RESET after editing filter parameters. Since the filter shapes the servo command signal, running with inactive filters changes axis behavior and can provoke following-error problems.
Likely causes
- typo/out-of-range value in filter frequency parameter
- order/frequency combination not permitted by the CNC
- parameters loaded from another machine model
Triage note: Correct frequency and order values per the 8055 parameter manual for each affected axis/spindle.
