An adjustment of these values via a serial interface only makes sense, if
the parameter for the identification is on >off<.
If the identification is adjusted (see page 36), the control parameters Xp,
Tn and Tv of a control course are determined and stored automatically.
Therefore the adjusted values are overwritten.
