FANUC Alarm SVGN-122 — Pressure is not invertible.

Description

The specified pressure cannot be used, it does not lie on the calibration curve (2nd order).

Remedy

Change the calibration method to the multi-linear segment method if possible. Do this by setting the system variables $sgsyscfg.$cal_model = 12 and $sgsyscfg.$frc2spd_cnv = 3, then perform the pressure calibration again. Alternatively, perform pressure calibration again, or reduce max pressure.
