Example 2 (Pr.5-07 = d2): Continuously executes program cycles

The diagram below shows the PLC program stepping through each speed and the

automatically starting again. To stop the PLC program, one must either pause the

program or turn it off (Refer to Pr.4-05 to 4-08 value d17 and d18).

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.
