Description: Displays the direct-axis voltage setpoint Ud.
Index: [0] = Unsmoothed
[1] = Smoothed with p0045
Description: Displays the quadrature-axis component of voltage setpoint Uq.
Index: [0] = Unsmoothed
[1] = Smoothed with p0045
Description: Defines the gain of the controller for resonance damping for operation with encoderless vector control in the range
that current is impressed.
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 bit 12 in status word p1408 is set.
Dependency: If a stalled drive is detected (p1408.12 set), fault F07902 is output after the delay time set in p2178.
Refer to: p2178
Note: Monitoring is only effective in the low-speed range (below p1755 * (100% - p1756)).
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)).
