Table 84: Hysteresis with an inverted direction of rota-
tion
The parameter ENIF_AUTO selects whether at startup
the incremental interface is enabled after the converter
has found its operating point or if the counting to the
absolute angle can be seen at the incremental interface.
The incremental counter has an integrated hysteresis
which prevents multiple switching of the incremental
signals at the reversing point. Hysteresis φ_hys must first
be exceeded before edges can again be generated at
A or B. This hysteresis can be set within a range of 0°
to 0.35° according to Table 84 and is referenced to 360°
of a singleturn cycle.
