Cause : Inductance measurement out of range or motor saturation not detected comes when RFC-S mode when the drive has detected that the motor inductances are not suitable for the operation being attempted. The trip is either caused because the ratio or difference between Ld and Lq is too small or because the saturation characteristic of the motor cannot be measured.

If the saturation characteristic of the motor cannot be measured this is because when the flux in the motor is changed the measured value of Ld does change sufficiently due to saturation to be measured. When half of Rated Current (05.007) is applied in the d axis of the motor in each direction the inductance must fall change at least (K / (2 x Full Scale Current Kc (11.061))
