Chapter 11 Motion Control Instructions
11-25
2. Motion Curve and Timing Chart
When Vel_Ex changes from FALSE to TRUE, Vel_Bsy changes to TRUE. One cycle later,
Vel_Act changes to TRUE and the execution of the velocity instruction starts. When the target
velocity is reached, Vel_Invel changes to TRUE and Vel_Bsy and Vel_Act remain TRUE.
When Vel_Ex changes from TRUE to FALSE, Vel_Inve, Vel_Bsy and Vel_Act remain TRUE.

Below is the example that one MC_MoveVelocity instruction aborts another MC_MoveVelocity
instruction.
