How Delta VFD Continuously Execute Internal PLC Steps

Let's talk about the mode two of Delta VFD's internal PLC. As we have discussed in the previous lesson/article that we have an internal PLC in Delta VFD.  In this lesson, we are going to learn how to make parameter setting which continuously execute program cycles.

Let's move to parameter number 78 and and select 02 which means this program will be continuously execute all seven steps that we have entered. This will operate motor in 1st step in the start, then move forward step by step and complete all 7 steps speed frequencies, and then start from first again.

If you will set "03" in parameter number 78. This will execute one program cycle step by step. This means motor will stop once program cycle will be completed and then will start again.
