Note: The above diagram shows one complete PLC cycle. To restart the cycle, turn the PLC
Program input off and then back on.
Example 2 (Pr.78 = 02) Continuously executes program cycles:
The diagram below shows the PLC program stepping through each speed and then
automatically starting again. To stop the PLC program, either pause or stop the program.

Example 3 (Pr.78 = 03) Execute one cycle step by step:
This example shows how the PLC function can perform one cycle at a time, within a complete
cycle. Each step will use the accel/decel times in Pr.10 to Pr.13. It should be noted that the
time interval for each step may be shorter than expected due to the time required for
acceleration and deceleration.
