2 Parameters

2.2 List of parameters

Description: Displays the stator leakage inductance of the 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

resistance (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.

Description: Displays the actual stator resistance (phase value).

The parameter value also contains the temperature-independent cable resistance.

Dependency: In the case of induction motors the parameter is also affected by the motor temperature model.

Refer to: p0350, p0352, p0620

Note: In each case, only the stator resistance of the active Motor Data Set is included with the stator temperature of the

thermal motor model.
