The parametering of the Function block appears through specification of the boost factors GAIN as well as the parametering of the Derivative time constants LEAD and the delay time constants LAG.
For very small sample times and the unit jump to input
IN (jump at line-in
IN from 0 to 1.0) output
OUT will jump to the value

(theoretical value - actual slightly smaller, due to the not infinitely small sample times), using the time constant
LAG to approximate the value

closer.
Two operating modes can be selected through the TR_S parameter input.

The Function block will be handled as " Parametering" describes.

The tracking value TR_I is transferred directly to the output OUT.
