Siemens SINAMICS G120X - CO: Motor Model Speed Adaptation Proportional Component; Motor Model Changeover Delay Time Closed-Loop Control

p1769[0...n] Motor model changeover delay time closed-loop control / MotMod t cl_ctrl
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
0 [ms]
Max:
10000 [ms]
Factory setting:
0 [ms]
Description: Sets the wait time for a transition from open-loop controlled to closed-loop controlled operation after twice the lower
changeover speed p1755 * (1 - p1756 / 100 %) has been exceeded - and below the upper switchover speed p1755.
Dependency: See also: p1755, p1756
Note
With p1759 = 0 ms and above p1755, the delay time becomes ineffective and the model changeover is determined by
the output frequency only (changeover for p1755).
r1770 CO: Motor model speed adaptation proportional component / MotMod n_adapt Kp
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2000 Dynamic index: -
Unit group: 3_1 Unit selection: p0505 Function diagram: 6730
Min:
- [rpm]
Max:
- [rpm]
Factory setting:
- [rpm]
Description: Displays the P component of the controller for speed adaptation.
r1771 CO: Motor model speed adaptation I comp. / MotMod n_adapt Tn
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2000 Dynamic index: -
Unit group: 3_1 Unit selection: p0505 Function diagram: 6730
Min:
- [rpm]
Max:
- [rpm]
Factory setting:
- [rpm]
Description: Displays the I component of the controller for speed adaptation.
p1774[0...n] Motor model offset voltage compensation alpha / MotMod offs comp A
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
-5.000 [V]
Max:
5.000 [V]
Factory setting:
0.000 [V]
Description: Sets the offset voltage in the alpha direction; this compensates the offset voltages of the drive converter/inverter at low
speeds. The value is valid for the rated (nominal) pulse frequency of the power unit.
Note
The value is pre-set during the rotating measurement.
p1775[0...n] Motor model offset voltage compensation beta / MotMod offs comp B
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
-5.000 [V]
Max:
5.000 [V]
Factory setting:
0.000 [V]
Description: Sets the offset voltage in the beta direction; this compensates the offset voltages of the drive converter/inverter at low
speeds. The value is valid for the rated (nominal) pulse frequency of the power unit.
