Howdy all,
I'll try to keep things general at the moment, but I'm looking to learn how to control my huanyang VFD via modbus with an arduino UNO. The initial "basic" end goal is having some preset speeds programmed in, so that I can hit "button 1" on a controller for "speed 1", button 2 for "speed 2" and so on... I'd also like to implement an e-stop and reverse function.
Simple, right?
My problem is, where do I start? I have a very basic understanding of some of the concepts at play, but other than that, I'm pretty much at square 1 here.
I've seen a few videos on youtube showing completed circuits and basic controls, but not much info on how to get to that point. Can somebody point me to some resources for where to start? For example, getting started with Modbus in general, integrating into arduino, etc...
Right now I'm using the VFD to control a knee mill, and have an external forward, stop, reverse switch wired into it, and I'm using the built in key pad for speed control, but as I said, I'd like to use an arduido to streamline the controls a bit.
Thanks in advance for and advice/direction.
