7.11.13 Example: Hydraulic position control
This example shows which parameters must be set in order to control the position
and speed of a hydraulic cylinder with a linear encoder. The motor and encoder
must be parametrised before the hydraulic control settings can be made.

The next step is for the pump specifications – as found on the rating plate or data
sheet – to be entered in P 2851 - HYD_Pump. This is also where the minimum and
maximum speed limits for the pump, the pump displacement volume and the gear
ratio between the motor and the pump are set.
