Layout of the
Control word (see page 317).
Profile velocit
y Y2 and Y4 do have the same function, they differ only in the word
width.
The same applies for Profile acceleration U16 / 832 and Profile deceleration U16 /
U32.
You should therefore only use one of these two values.
The meanings of the assignments change with the Gearing motion function:
Target position (position com-
mand value)
= Gearing numerator
