2.2 List of parameters
Notice: - For the droop, generally values up to 10 % are practical (p50227 = 0.000 ... 0.100). Under certain circumstances,
higher values can result in an unstable response of the speed controller.
- The droop is entered as absolute factor without any dimensions and it is especially important to note that it is not a
percentage.
Example:
Set droop = 5 % --> p50227 = 0.05
Note: The adaptation of the droop is defined using 2 pairs of values.
Pair of values 1:
p50558/p50552 (x/y coordinate)
Pair of values 2:
p50561/p50227 (x/y coordinate)
Description: Sets the smoothing time constant for smoothing the speed setpoint on the speed controller.
Recommendation: If the ramp-function generator is being used, setting lower values may be sensible.
Note: The value is set automatically during the optimization run for the speed controller to the same value as the integral
time (Tn) (p50051 = 26).
Description: Setting for the control of the integral component tracking on the speed controller.
Value: 0: Tracking ON
1: Tracking OFF
Dependency: Refer to: p50084, p50687
Note: p50229 = 0:
Tracking of the integral component on the speed controller activated. The speed actual value is used as speed
setpoint and the integral component of the speed controller is tracked so that r52148 = r52140 results.
p50229 = 1:
Tracking of the integral component on the speed controller de-activated.
Description: Sets the duration for setting the integral component on the speed controller.
Following a positive edge on binector input p50695, the integral component of the speed controller is set to the value
of the signal source set at connector input p50631.
