Siemens SINAMICS G120XA - Motor Magnetizing Inductance; Mot Lh; Motor Rotor Time Constant; Damping Time Constant D Axis

NOTICE
When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note
If the rotor leakage inductance (p0358) for induction motors is changed outside the commissioning phase (p0010 > 0),
then the magnetizing inductance (p0360) is automatically adapted to the new EMF (r0337). You are then advised to
repeat the measurement for the saturation characteristic (p1960).
p0360[0...n] Motor magnetizing inductance / Mot Lh
Access level: 3 Calculated: CALC_MOD_EQU Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: MDS, p0130
Unit group: - Unit selection: - Function diagram: 6727
Min:
0.00000 [mH]
Max:
10000.00000 [mH]
Factory setting:
0.00000 [mH]
Description: Sets the magnetizing inductance of the motor.
This parameter value is automatically calculated using the motor model (p0340 = 1, 2) or using the motor identification
routine (p1910).
NOTICE
When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note
The parameter is not used for synchronous motors (p0300 = 2).
r0384[0...n] Motor rotor time constant / damping time constant d axis / Mot T_rotor/T_Dd
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: - Dynamic index: MDS, p0130
Unit group: - Unit selection: - Function diagram: 6722, 6837
Min:
- [ms]
Max:
- [ms]
Factory setting:
- [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 resistance
(p0354). The temperature adaptation of the rotor resistance for induction motors is not taken into account.
r0394[0...n] Rated motor power / Mot P_rated
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: - Dynamic index: MDS, p0130
Unit group: 14_6 Unit selection: p0100 Function diagram: -
Min:
- [kW]
Max:
- [kW]
Factory setting:
- [kW]
Description: Displays the rated motor power.
Note
The parameter displays p0307. For p0307 = 0, r0394 is calculated from p0304 and p0305 (only for induction motors).
Depending on the actual motor type, deviations can occur from the actual rated motor power.
