Setpoint for pressure, volumetric flow rate, cylinder speed, cylinder position. The unit
(HYD_UNIT) depends on the control mode and corresponds to bar for pressure
control, l/min for volumetric flow rate control and rpm for pump speed control. For
cylinder position and speed control, the unit corresponds to the UserUnit selected in
the scaling (chapter 8.2). This also applies for derivative 1 and 2 or speed and
acceleration.

Hydraulic control parameters table
For the control of the valve position, switching of the position controller settings and
of the pump data set as well as for enabling the active decompression, the
respective bits can be enabled in this parameter for every motion block. The active
decompression prevents that a motion block is started as long as pressure is still
applied. If the bit is active, the pressure is reduced via a defined ramp (P 2850.11
decmpRate) below a specified pressure level (P 2850.10 decmpLvl) before the
respective motion block is started.
