r1733[0...1]

CO: Quadrature-axis voltage setpoint / Quad U set

Access level: 4
Can be changed: -
Unit group: 5_1
Min:
- [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
Can be changed: T, U
Unit group: -
Min:
0.000
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
Can be changed: T, U
Unit group: -
Min:
0.0 [%]
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.
See also: 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
Can be changed: -
Unit group: -
Min:
- [%]
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)).
