Delta Electronics VFD-G manual Example 2 Pr.05-15 = 2 Continuously executes program cycles

Chapter 4 Parameters

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.

Step operation indication

Program operation fulfillment indication

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).
