Parameter list
r0384[0...n] Motor rotor time constant / Mot T_rotor
VECTOR Can be changed: -
Data type: Floating Point
P-Group: Motor
Min
- [ms]
Description: Displays the rotor time constant.
Note: The parameter is not used for synchronous motors.
The value is calculated from the sum of the inductances on the rotor side (p0358, p0360) divided by the rotor resis-
tance (p0354). The temperature adaptation of the rotor resistance is not taken into account.
r0386[0...n] Motor stator leakage time constant / Mot T_stator leak
VECTOR Can be changed: -
Data type: Floating Point
P-Group: Motor
Min
- [ms]
Description: Displays the stator leakage time constant.
Note: The value is calculated from the sum of all leakage inductances (p0233*, p0353**, p0356, p0358) divided by the
sum of all motor resistances (p0350, p0352*, p0354).
The temperature adaptation of the resistances is not taken into account.
* only applies for VECTOR (r0107).
** only applies for SERVO (r0107).
r0395[0...n] Stator resistance, actual / R_stator active
VECTOR Can be changed: -
Data type: Floating Point
P-Group: Motor
Min
- [Ohm]
Description: Displays the actual stator resistance (phase value).
The parameter is influenced by the temperature model and includes the temperature-independent cable resistance.
r0396[0...n] Rotor resistance, actual / R_rotor active
VECTOR Can be changed: -
Data type: Floating Point
P-Group: Motor
Min
- [Ohm]
Description: Displays the actual rotor/secondary section resistance (phase value).
The parameter is influenced by the temperature model.
Note: This parameter is not used for synchronous motors (p0300 = 2xx).
