The scaling of the units is performed in the motion profile of the standard motor
control. A scaling assistant is available for this purpose (“Scaling / Units” button).

Because a volumetric flow rate control underlies the position control, the following
settings must be made beforehand.
The parameter P 2840[8] - QActCalc can be used to select whether the volumetric
flow rate value is to be taken from a sensor (MEAS(0) = From measurement) or, as in
this example, determined by means of a calculation using the cylinder speed and
the pump displacement volume (CYL(1) = From cylinder speed).

The position controller is a PI controller. The control dynamics can be set using
P 2848 - HYD_PosCon.
