Description: Displays the stator leakage inductance of the motor including the motor reactor (p0233).
Description: Displays the stator longitudinal inductance of the synchronous motor including the motor reactor (p0233).
Description: Displays the magnetizing inductance of the motor.
Note: The parameter is not used for synchronous motors (p0300 = 2xx).
Description: Displays the rotor time constant.
Note: The parameter is not used for synchronous motors.
The value is calculated from the total of the inductances on the rotor side (p0358, p0360) divided by the rotor resis-
tance (p0354). The temperature adaptation of the rotor resistance for induction motors is not taken into account.
Description: Displays the stator leakage time constant.
Note: The value is calculated from the total of all leakage inductances (p0233, p0356, p0358) divided by the total of all
motor resistances (p0350, p0352, p0354). The temperature adaptation of the resistances is not taken into account.
