5.132.3
System deviation in the area of reduced sensitivity
A reduced controller dynamics with low system deviations causes a positive influence on the dam-
ping behaviour of the control loop.
• C04377 serves to set a tolerance window, in which the system deviation is transferred to the
controller with a slight gain.
• C04376 serves to set the required gain reduction in the defined tolerance window in percent.
5.132.4
Controller influence
The dnInfluence_n input serves to evaluate the dnOut_n controller output in percent. The evaluated
output signal is provided at dnOutRed_n.
