The Autotuning procedure measures the Stator Resistance (Rs) and the Leakage Inductance (Lf) of the motor (except for the synchronous motor).

The Stator Resistance (Rs) and the Rotor Resistance (Rr) are thermally compensated.

This allows the calculation for the automatic compensation of stator voltage drops and the optimization of the motor model for vector control (higher torque at low speed).
