Hello, Recently I bought this Can anybody help me how to connect it to ARDUINO to be possible to switch it on/off and set the speed via Openbuilds control software? Thank You
You cannot use an Arduino, it needs a 0-10v signal. Treat yourself, upgrade the Arduino to BlackBox: docs:blackbox:connect-vfd [OpenBuilds Documentation]
Thank You for Your response. When I wrote Arduino I mean controller "based" on Arduino. Actually it is Phoenix CNC Controller: As You can see it has all necessary pins to connect VFD. The problem is actually in VFD itself. Which one here are spindle enable and PWM+ and PWM- ?
OK, it has 0-10v - follow the link I gave earlier - at the very bottom is links to wiring written up by forum members
If you want to use arduino to control the vfd. You can do what I did. I used this: https://www.amazon.com/WOWOONE-Conv...uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl take the PWM from the arduino, connect to this which converts it to the 0-10v signal needed for the vfd.
Yes, thanks, I know it. My controller already has this module onboard. It was just about finding out in VFD pins, which one should be connected to the controller.
