Result:
1 encoder increment corresponds to 0.017166 increments of the internal unit.
The encoder resolution is thus coarser than the computational resolution by a factor of 58.

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