r1733[0...1] CO: Quadrature-axis voltage setpoint / Quad U set
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2001 Dynamic index: -
Unit group: 5_1 Unit selection: p0505 Function diagram: 6714, 6731
Min:
- [Vrms]
Max:
- [Vrms]
Factory setting:
- [Vrms]
Description: Display and connector output for the quadrature axis voltage setpoint Uq.
Index: [0] = Unsmoothed
[1] = Smoothed with p0045
p1740[0...n] Gain resonance damping for encoderless closed-loop control / Gain res_damp
Access level: 3 Calculated: CALC_MOD_CON Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
0.000
Max:
10.000
Factory setting:
0.025
Description: Defines the gain of the controller for resonance damping for operation with sensorless vector control in the range that
current is injected.
p1745[0...n] Motor model error threshold stall detection / MotMod ThreshStall
Access level: 3 Calculated: CALC_MOD_REG Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
0.0 [%]
Max:
1000.0 [%]
Factory setting:
5.0 [%]
Description: Sets the fault threshold in order to detect a motor that has stalled.
If the error signal (r1746) exceeds the parameterized error threshold, then status signal r1408.12 is set to 1.
Dependency: If a stalled drive is detected (r1408.12 = 1), fault F07902 is output after the delay time set in p2178.

Note
Monitoring is only effective in the low-speed range (below p1755 * (100% - p1756)).
r1746 Motor model error signal stall detection / MotMod sig stall
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
- [%]
Max:
- [%]
Factory setting:
- [%]
Description: Signal to initiate stall detection
Note
The signal is not calculated while magnetizing and only in the low speed range (below p1755 * (100 % - p1756)).
