Parameters
List of Parameters
r0377[0...n]
Motor leakage inductance, total / Mot L_leak total
Access level: 4
Unit: [mH]
Description:
Displays the stator leakage inductance of the motor including the motor reactor (p0233).
r0378[0...n]
Motor stator inductance, d axis / Mot L_stator_d
Access level: 4
Unit: [mH]
Description:
Displays the stator longitudinal inductance of the synchronous motor including the motor reactor (p0233).
r0382[0...n]
Motor magnetizing inductance transformed / Mot L_magn transf
Access level: 4
Unit: [mH]
Description:
Displays the magnetizing inductance of the motor.
Note:
The parameter is not used for synchronous motors (p0300 = 2xx).
r0384[0...n]
Motor rotor time constant / damping time constant d axis / Mot T_rotor/T_Dd
Access level: 3
Unit: [ms]
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.
r0386[0...n]
Motor stator leakage time constant / Mot T_stator leak
Access level: 4
Unit: [ms]
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.
r0395[0...n]
Actual stator resistance / R_stator act
Access level: 3
Unit: [Ohm]
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.
r0396[0...n]
Actual rotor resistance / R_rotor act
Access level: 3
Unit: [Ohm]
Description:
Displays the actual rotor resistance (phase value).
The parameter is affected by the motor temperature model.
Dependency:
Refer to: p0354, p0620
Note:
In each case, only the rotor resistance of the active Motor Data Set is included with the rotor temperature of the
thermal motor model.
This parameter is not used for synchronous motors (p0300 = 2xx).
