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

VFD-F Series

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 speed (sets the frequency of each step speed)

Pr.04-00 to 04-07:Multi-Function Input Terminals (set one multi-function terminal as 32 - PLC auto-operation).

Multi-Function Output Terminals (set a Multi-Function Terminal as Pr.03-00 to 03-07: 34-PLC running indication, 35-PLC step completed or 36-PLC

program completed).

Pr.05-16: Direction of operation for the 1st to 15th step speed. Pr.05-17 to 05-31: Operation time setting of the 1st to 15th step speed.

Note: The above diagram shows one complete PLC cycle. To restart the cycle, turn the 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 continuously executes the program. To stop the PLC program, one must either pause the program or turn it off. (Refer to Pr.04-00 to 04-07 values 32 and 33).
