Rotary axes are subject to certain restrictions in the choice of gear ratio, as shown
in Figure 9-5. These restrictions arise from the need to reproduce the actual posi-
tion accurately over several revolutions when referencing with one periodic zero
pulse per motor revolution (type of reference point approach < 4). See also “De-
pendencies”, Section 5.3.1).
