Setting the wobble generator

Functionality
The wobble generator executes predefined periodical disruptions superimposed on the main
setpoint for technological usage in the fiber industry. The wobble function can be activated
via P2940. It is independent of the setpoint direction, thus only the absolute value of the
setpoint is relevant. The wobble signal is added to the main setpoint as an additional
setpoint. During the change of the setpoint the wobble function is inactive. The wobble signal
is also limited by the maximum frequency (P1082).
