In order to adapt the actual-value resolution to the calculation resolution, the control
calculates the quotients from the "internal increments/mm" and the "encoder increments/mm"
as follows:

The distance for linear encoders is based on the pulse increments.

In order to adapt the actual-value resolution to the calculation resolution, the control
calculates the quotients from the "internal increments/mm" and the "encoder increments/mm"
as follows:
