The filter key data is defined in MD 5284, MD 5285 and MD 5288 to MD 5290.
Enter the natural frequency for control output filter 1 (PT2 low-pass). Setting a
value of <10 Hz for the natural frequency of the low pass initializes the filter as a
proportional element with a gain of 1, irrespective of the associated damping.
