Posted 21 Dec 2021 You would have to provide a lot more detail. Like how is the VFD being controlled? Analog? Network? You can certainly write logic so that when an input is triggered, a new speed can be set. Share this post Link to post Share on other sites
Posted 23 Dec 2021 the speed ref is being sent to the VFD from a DA3605 or a DA3603 depending on the VFD Share this post Link to post Share on other sites
Posted 23 Dec 2021 So based on a physical input, you can move a numeric value into the variable you attach to the analog output. Share this post Link to post Share on other sites
