Hi all,
Have finally got axis movement 
I am now on to setting up my VFD - model number A2-8022 (https://www.ebay.com/itm/313387171700), manual attached - FYI
Was planning on controlling it with a usb to RS485 adapter (https://www.amazon.co.uk/dp/B0721BB8PQ?psc=1&ref=ppx_pop_dt_b_asin_title) as i would like Mach 3 to control it.

I see that the Huanyang VFD has a plug in written for it, will that work on my VFD?

Any issues anyone can foresee?
and with that any guidance?

Thanks in advance.

I have a similar A2 series VFD and am trying to figure out how to get Mach3 control it as well. Did you ever get yours to work and if so what did you do? I haven't been able to find much information on this VFD.

Most VFD's need a parameter setting to enable external control as they default to the pot and keys on the front.

Then you need to set the input parameter for control to PVM or 0-10V or what ever your system outputs then all you should need is to connect the run/fwd switch to your relay and configure spindle output in ports and pins.

Some pictures of the VFD will help us to give you better info.

If this is the correct manual the Pn03 and Pn04 nee to be set for external control.
