7.1.12 p/flow control
The p/flow control mode is selected by setting the parameter <ControlMode> (0x6043) to 14 (p/flow control).

7.1.13 Sample frequency
The <BasicSampleFrequency> (0x3030) is the frequency of the real time control loop. With this frequency the
actual spool position is calculated from the LVDT signal and, i.e. the current controller, pressure controller and
spool position controller are calculated.

The signal #PressureSetpoint# is an internal signal only. It links the signal from the pressure set-
point value path to the pressure demand value generator.
