Note about the electronic motor model
A model change takes place within the speed range p1752 · (100 % - p1756) and p1752.
With induction motors with encoder, the torque image is more accurate in higher speed
ranges; the effect of the rotor resistance and the saturation of the main field inductance are
corrected. With synchronous motors with encoder, the commutation angle is monitored. If
the kT estimator has been activated, the torque image for synchronous motors is more
accurate too.
