Example 3 (Pr. 5-07 = d3) Execute one cycle step by step:

The example shows how the PLC can perform one cycle at a time, within a complete cycle. Each step will use the acceleration/deceleration times in Pr.1-09 to Pr.1-12. It should be noticed that the time each step spends at its intended frequency is diminished, due to the time spent during acceleration/deceleration.

Example 4 (Pr. 5-07 =d4) Continuously execute PLC cycles step by step:

In this explanation, the PLC program runs continuously step by step. Also shown are examples of steps in the Reverse direction.
