Example 3 (Pr. 5-03 = 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 accel/decel 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 accel/decel.
