
As Rel_Ex changes from FALSE to TRUE, MC_MoveRelative instruction execution starts and
MC_SetPosition is executed 3 seconds later after MC_MoveRelative is executed.

The command position is 6000 as MC_SetPosition starts being executed and 4000 after the
instruction execution is completed. The position is 8000 as MC_MoveRelative execution ends.

MC_SetPosition does not affect the motion which is being performed through observing the
above velocity change curve.

Programming Example 3
The following example shows how MC_SetPosition execution affects MC_MoveAbsolute instruction
which is being executed. The actual execution effect of MC_MoveAbsolute which is being executed is
not be impacted by MC_SetPosition.
