The application of absolute and incremental position control is various and multiple. This kind of position
control is equal to a simple sequence control. User can easily complete the cycle running by using the
above table. For example, the position command, P1 is 10 running and P2 is 20 running. Give the
position command P1 first and then give the position command P2. The difference between absolute
and incremental position control is shown as the figure below:
