Description: Displays the stator inductance identified for the 4th point of the saturation characteristic.
Index: [0] = Phase U
[1] = Phase V
[2] = Phase W
Description: Displays the identified IGBT threshold voltage.
Index: [0] = Phase U
[1] = Phase V
[2] = Phase W
Description: Displays the identified effective valve lockout time.
Index: [0] = Phase U
[1] = Phase V
[2] = Phase W
Description: Displays identified rotor resistance (on separately excited synchronous motors: damping resistance).
Index: [0] = Phase U
[1] = Phase V
[2] = Phase W
Description: Sets the configuration of the rotating measurement.
For bit 12 = 1:
The selection only has an effect on the measurement p1960 = 1, 2. For the shortened measurement, the magnetizing
current and moment of inertia are determined with a somewhat lower accuracy.
