7.11.5 Cylinder configuration
If no volumetric flow rate sensor is employed, the volumetric flow rate can be
calculated using a linear encoder and the cylinder geometry (P 2840.8 QActCalc).
To do so, various different cylinder dimensions must be passed to the servo drive.
The different surface areas of the piston and ring side must be kept in mind because
either more or less medium is required for the same path depending on the power
direction.

The parameters which must be set are P 2852[0] - cylArea1 and P 2852[2] -
cylArea2.
Cylinder piston surface area A1 = cylAreal1 = A1 in cm²
Cylinder ring surface area A2 = cylAreal2 = A2 in cm²
