Example:
set of set-points
control bit
change on set-point
= 0/1
control bit
change set immediately
= 0
While a Positioning is in progress, the set point is changed.
Change on set point = 0 Current target position will be stopped at. After the posi-
tion is reached, the new set point is taken over.
Change on set point = 1 The current target position will be driven to in current
speed. As soon as the position is reached, the new set
point is taken over.
The grey line in segment "actual speed" shows the actual speed behaviour if control
bit
change of set- point is set (= 1).
