I’ve built my system with a 2.2 KW Huanyang VFD and spindle instead of a router but I ended up purchasing GT series VFD instead of the HY series discussed in the YouTube videos I’ve found.
PC.02 (Data Format) = 0 (RTU, 1 start bit, 8 data bits. no parity check, 1 stop bit)
Within the Onefinity SW I set the tool type to Huanyang
Set the Max spin to 24000
Set the Bus-ID to 1, the baud to 9600 and the parity to None
Net Result – No Connection??
I’m probably missing something, most likely, or maybe the Onefinity code is setup for the HY series exclusively?
Oh, one other thing: the comm hookup on the GT VFD is 485+ & 485- instead of RS+ & RS-. I’m pretty sure it’s the same thing and that it’s not significant though?
If you have any insights, I’d sure appreciate hearing from you.
I expect you are right that it shouldnt make any difference.
What you really need is a person on the forum who has the same VFD up and running with respect to setting up the manual configuration in the onefinity controller and the corresponding configuration in the VFD .
I had trouble setiing my VFD up
Things to check:
connectivity from the vfd to breakout board.
make sure the breakout board is fully engaging with the controller.
then methodically read the buildbotics manual and the vfd manual, try out combinations of setting and record what you did and the results.
from what i have seen in the forums it is typical to have to set frequency, current and voltage settings in the vfd. You dont have them listed above.
Try swapping rs+/rs-

And many other youtube and forum posts.
Mr VFD @Aiph5u seems to be away from the forums at the moment. He answered many peoples questions. Theres also facebook.
Did you get your VFD working. i just got a GT Series and have it running with Modbus.
I used the Custom VFD from the pull down instead of Huanyang. I think the Huanyang shownb is for the HY model.
I used the same setting you show above with Pin 13 going to 485+ and pin 14 going to 485-.
In addition to the settings you show on the VFD I also made the following changes.
P0.021 - 2 (Run Command from Communication)
P0.07 - 7 (Frequency from Remote Communication)
In the Onefinity tool menu with custom VFD selected then press the customize button and input the register data. In the Huanyang Manual the numbers are in Hexadecimal but you need input regular decimal into the chart. If am posting properly my settings are shown on the pic below. Yours may be different so confirm everything for your own machine. I am by no means an expert so I could be giving horrible advice.
Bumping this thread because I feel like it’s gotten me close to the finish line.
I have an HY GT series VFD. At first, I wasn’t seeing any communication between the BB control box and the VFD, but swapping the 485+/- solved that.
Selecting “Huanyang VFD” from the dropdown in the Tool page didn’t seem to be working, so I tried Robalot’s custom modbus settings on this page. Modbus status on the Tool page now shows connection as ‘ok.’
When I run g-code, the VFD fan spins up, but the spindle doesn’t spin and the front panel reads 0 (I assume that’s the Freq).
Before connecting the VFD to the BB control box, the spindle fired up from the front panel controls just fine, so I feel like the basic functionality is in place but something else is wrong with the BB-to-VFD communication.
Brief update:
Can’t get the spindle to turn with the freq-set command, but I’ve found that it will with the freq-scaled-set and a value greater than 100… unfortunately, it seems to spin at an indicated 6k rpm regardless of what the gcode calls for.
Sorry for the additional bump, but I thought that it’d be good to share my success, if it might help others down the line.
I was on the right track with freq-scaled-set, but my mistake (realized late last night) was that the value range is -10,000 to 10,000, which represents -100% to 100%. By entering 100, 200, 1000, I was telling it to request 1%, 2%, 10% of the desired freq/rpm and then the spindle was defaulting to the min rpm value, instead. By changing the value to 10000, I’m getting 100% of the desired freq/rpm, and it’s tracking speed changes in gcode as it should.
So, final answer for my Huanyang 2.2kw GT Series: the VFD configuration of both @gstuff and @Robalot, and with a slight change to Robalot’s Custom Modbus configuration, with “freq-set” changed to “freq-scaled-set”, pointed at the same 8192 address and with a Value of 10000.
…now I just need to figure out how to trigger the relay on that IOT power strip that I have hooked up to the water pump…
Yeah, his videos are the reason that I purchased that IOT relay strip in the first place. His work should be a good start, but the GT series is a little different, so I think that I’ll have to poke around a bit to make it work.
