2 Parameters
2.2 List of parameters
Description: Display and connector output for the quadrature axis voltage setpoint Uq.
Index: [0] = Unsmoothed
[1] = Smoothed with p0045
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.
Note: Monitoring is only effective in the low speed range.
Description: Signal to initiate stall detection
Note: The signal is not calculated while magnetizing and only calculated in the low speed range.
Description: Minimum operating frequency for rugged operation.
If the minimum value is greater than the lower changeover limit parameterized with p1755 * (1 - 2 * p1756), then the
difference is displayed using p1749 * p1755. The parameter value cannot be changed.
Dependency: Refer to: p1755, p1756
Description: Sets the speed to change over the motor model to encoderless operation.
Dependency: Refer to: p1749, p1756
Notice: The changeover speed represents the steady-state minimum speed up to which the motor model can be used in
sensorless steady-state operation.
