The mass of the drive is a critical parameter and should be calculated as
exactly as possible!

The mounting position of the cylinder (MD 5151) specifies to what degree the
force due to weight of the moved mass (MD 5150) is taken into account in cal-
culating the servo gain and maximum piston travel-in/travel-out speed.
It is assumed that the moved mass will act in the direction of the cylinder axis. If
the weight of the moved mass does not act in this direction, however, MD 5151
must be converted accordingly.
A distinction is made between two different mounting methods in the HLA:
1. The cylinder is stationary, the moved mass is attached to the piston rod (MD
5152 bit 0=0).
2. The piston is stationary, the moved mass is attached to the cylinder (MD
5152 bit 0=1).
The Calculate drive model data routine calculates the weight force applied to
the cylinder from MD 5150...MD 5152 and enters the result in MD 5231.
