Chapter 11 Motion Control Instructions
11-85
2. Motion Curve and Timing Charts:
As Abs_Ex changes from FALSE to TRUE, the execution of MC_MoveAbsolute instruction is
started and MC_SetPosition is executed 3 seconds later after MC_MoveAbsolute is executed.
The command position is 6000 as MC_SetPosition starts being executed and 11000 after the
instruction execution is completed. The position is 15000 as MC_MoveAbsolute execution
ends.
It can be seen that MC_SetPosition does not affect the actual execution effect of
MC_MoveAbsolute which is being executed through observing the above velocity change
curve.
