Determining the counting direction of the measuring system
The counting direction is determined depending on the measuring system.
Measuring systems from Heidenhain
Note
The counting direction of the measuring system is positive, if the distance between the
sensor head and rating plate increases.

Figure 2-37 Determining the counting direction for measuring systems from the Heidenhain Company
Measuring systems from Renishaw (e.g. RGH22B)
As the reference mark for the Renishaw RGH22B has a direction-dependent position, with
control cables BID and DIR, the encoder must be parameterized, so that the reference mark
is only output in one direction.
The direction (positive/negative) depends on the geometrical arrangement at the machine
and the reference point approach direction.
