2.3.4 Load
For good positioning behaviour, the CMAX must be adjusted
to the load. Here, the load represents the total mass to be
moved with the positioning drive, includ
ing the weight of the
piston and the slide. It consists of the mass of the workpiece
 which generally changes during the process  and all other
parts of the
drive with mass, such as pistons, piston rods,
slides, workpiece grippers or gripper units, etc. which are
defined during the design engineering, and generally do not
change:
Load = workpiece mass
+ total moving mass without workpiece
There is a maximum and a minimum permissible load. The
permissible load depends
on:
the type of drive used
the diameter of the drive used
the selected mounting position
the operating pressure.
Make sure that in all load situations the e
ffective load:
is at least equal to the minimum permissible load.
This especially applies when there is no workpiece.
If necessary, fasten an additional
mass / load to the slide.
The maximum permissible load must not be exceeded.
