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.
