2.2 List of parameters
Description: Sets the minimum time for falling below the changeover speed when changing from closed-loop controlled operation
to open-loop controlled operation.
Dependency: The wait time has no significance if the setpoint speed before the ramp-function generator lies in the open-loop
speed controlled operating range. In this case, the change is made without any delay.
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1755, p1756
Note: If p1758 is changed, commissioning must be selected in order to validate the value for the blocking monitoring.
Description: Sets the minimum time for a transition from open-loop controlled to closed-loop controlled operation after the lower
changeover speed p1755 * (1 - p1756 / 100 %) has been exceeded.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1755, p1756
Note: With p1759 = 2000 ms, the delay time becomes ineffective and the model changeover is determined by the output
frequency only (changeover for p1755).
Description: Sets the proportional gain of the controller for speed adaptation without encoder.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Description: Sets the integral time of the controller for speed adaptation without encoder
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
