Example 1 (Pr.05-15 = 1): Execute one cycle of the PLC program. Its relative parameter
settings are:
Pr.05-00 to 05-14: 1st to 15th step speeds (sets the frequency of each step speed)
Pr.04-00 to 04-03: Multi-Function Input Terminals (set one multi-function terminal as 32 - PLC
auto-operation).
Pr.03-00: Multi-Function Output Terminals (set a Multi-Function Terminal as 34-PLC
running indication, 35-PLC step completed or 36-PLC program completed).
Pr.05-16: Direction of the 1st to 15th step speeds.
Pr.05-17 to 05-31: Operation time setting for each corresponding step speed.

Note: The above diagram shows one complete PLC operation cycle. To restart this cycle, turn the
multi-function input terminal that designed as PLC program off and on again.
Example 2 (Pr.05-15 = 2): Continuously executes program cycles:
The diagram above shows the PLC program stepping through each speed. Set Pr.05-15 to 2 for
continuous program execution. To stop the PLC program, one must either pause the function or turn
it off. (Refer to Pr.04-00 to 04-03 values 32 and 33).
