I am setting up a Mophorn 220v 4KW air cooled spindle with an A2-8040 VFD Have read through the Openbuilds documentation for setting up the 0-10v analog signal to the Toolhead and have watched and read the manuals for the Huanyang & YL620-A VFD setups I found on the forum. I have identified 3 out of the 4 same terminals on my VFD compared to the others and I'm not seeing the additional GND connection, or don't know which terminal to pair with the GND I do have. I have included photos of the documentation and schematic. Would anyone have any insight or recommendations on how this would be setup?
Might be best to confirm with the VFD supplier. But in the absense of other GND pins, i suspect you can just gang up all the GNDs as a common GND. They may just have been displayed seperately in the schematic to avoid clutter
Thank you for the reply! I was considering the same thing with the common GND. I will give it a shot next weekend.
How did you make out? I would be interested in seeing some pictures if you are willing to share your outcome as I am trying to do the same. Thanks in advance.
