NOTE

The above diagram shows one complete PLC cycle. To restart the cycle, turn the PLC program off and then back on.

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).
