V700 Posted March 10, 2021 Report Share Posted March 10, 2021 Hi guys! I want to control a vfd with an analog signal 0-10V. The program is running on 2 phases, in the first phase i measure with my voltage meter the right value in the analog output, in the second phase i want the speed to change so i load a new value through the MI.Although that the new value is shown in the monitor, my voltage meter shows me the same voltage.

MVP 2021 Ausman Posted March 10, 2021 MVP 2021 Report Share Posted March 10, 2021 V700, we need to also see the phase 1 controls and how you switch b/n the two. I was so amazed at this layout that I quickly imitated it in Visi, not believing it compiled. It did. Over to someone else. cheers, Aus Quote Link to comment Share on other sites More sharing options...
MVP 2021 kratmel Posted March 10, 2021 MVP 2021 Report Share Posted March 10, 2021 Please try to use State machine Joe Tauser example for programming analog output setpoint change. Main idea - program can set only one setpoint in one selected by pointer step. I use it for vfd speed changeover on cutting machine and many other application.
