If p50230 = 0:
The integral component of the speed controller is set to the instantaneous value of the signal present at connector
input p50631.
If p50230 > 0:
The integral component of the speed controller is tracked continuously during the time set to the value of the signal
present at connector input p50631.
Description: Setting for enabling the proportional component for the speed controller.
Value: 0: Without proportional component
1: With proportional component
Description: Sets the dynamic response of the speed control circuit as the default for the speed controller optimization run.
Recommendation: On drives with gear backlash, for example, optimization should be started commencing with low dynamic response
values at and above 10%.
On drives with maximum requirements in terms of synchronous operation and dynamic response, values of up to 100
% can be selected.
Note: If this value is changed, the optimization run for the speed controller will have to be performed again before the new
value is applied.
Description: Sets the natural frequency of a PT2 element for the reference model of the speed controller.
Recommendation: The reference model is correctly set when the characteristics of r52154 (reference model output) and r52167 (actual
speed value) are virtually identical when the I component of the speed controller is disabled.
Dependency: In conjunction with p50238 and p50239, the characteristics (in time) of the P-controlled speed control loop can be
emulated.
