Huanyang VFD and spindle problem - VI/GND drawing voltage from my controller

Hi Gerry

Any better tutorials for setting up a VFD. Those are also the settings I was given by the supplier.

PD003 and PD04 should be set to 400, not what that website says. I don't know of any one definitive tutorial, but there are a lot of threads at CNC Zone with the correct settings. Look for posts from "Mactec".
And be aware, that there are also lots of posts with the wrong settings.

Hello Luke
Strange enough I have the very same problem. Exactly the same. But with another VFD (Fuling) and another board (Pokeys57CNC) and another Spindle. The VFD settings seem to be correct as I can perfectly operate the Spindle manually. But when I connect to the Board - as you did - I have the same effect as you had.
Therefore: Did you solve it? If yes: how? :-)

And hint is appreciated!

Unfortunately not. I ended up throwing in the towel and sending the board back which was a real shame as it looked like a good board. I ended up using a Arduino mega flashed with GRBL. I just upgraded to the new CNC xpro V4. Both used external drivers. I haven't had an issue since...
