2. Motion Curve and Timing Chart:
When Sup_Ex changes to TRUE, Sup_Bsy changes to TRUE. One cycle later, Sup_Act
changes to TRUE and the motion controller controls the servo motor to run by using current
position as the reference point.
After the servo motor completes the superimposed positioning, Sup_Done changes to TRUE
and meanwhile Sup_Bsy and Sup_Act change to FALSE.
When Sup_Ex changes to FALSE, Sup_Done changes to FALSE.
When Sup_Ex changes to TRUE again after the servo motor completes the set distance, the
motion controller controls the servo motor to run. When the servo motor completes the set
distance, Sup_Done changes to TRUE again.
