6.8.2 Angular incremental encoder interface as input (P0890 = 2, from
SW 3.3)
The angular incremental encoder interface (X461, X462) is set as input
with P0890 = 2, i.e. an incremental position reference value can be ent-
ered from an external control via terminals A+.x/A–.x, B+.x/B–.x and
R+.x/R–.x.
The incremental position reference values, entered via the angular in-
cremental encoder interface, are entered after the fine interpolator.
