Description: Defines the gain of the controller for resonance damping for operation with sensorless vector control in the range that
current is injected.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
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.
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p2178
Note: Monitoring is only effective in the low-speed range (below p1755 * (100% - p1756)).
Description: Signal to initiate stall detection
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: The signal is not calculated while magnetizing and only in the low speed range (below p1755 * (100 % - p1756)).
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: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1755, p1756
