Via P2876 HYD_AdvFilSel the filter can be activated and the input and output sizes
can be selected.
The actual pressure value P2843.1 pressAct in bar or the cylinder speed P2843.23
ActSpd in rpm (Cyl_nAct(2)) or in mm/s (Cyl_ActSpd(3)) are available as input
variables.
An additive speed setpoint (nFF(1)) or volume flow rate setpoint (volFF(2)) can be
selected at the filter output. The speed reference value is connected to the output of
the pressure control and the cylinder speed control. Selecting volFF(2) acts at the
output of the pressure control with volumetric flow rate output and the subordinate
