6.5.2 Definition of the reference point coordinate
In principle, three cases can be distinguished at the parameter setting of the reference
point coordinate.
6.5.2.1 Real Travel Range Z = Max. Travel Range X
If the max. Software Limit Switch Positions shall be kept, a displacement of the
Reference Point Coordinate is not possible.
The adjusted Reference Point must be considered as difference to both Software
Limit Switch Positions in order to avoid an exceeding of the Travel Range.

6.5.2.2 Real Travel Range < Max. Travel Range/2
Is the defined Travel Range smaller than ½ * Max. Travel Range a freely definable
Reference Point Coordinate can be transferred.
