Can anyone please tell me if it is possible to connect this VFD to my computer so that Mach3 can control the spindle?
And if it is possible, how to do so?
Thanks for your time.

You will require a 0-10v speed control, your BOB may or may not have this. Thou you can a buy a spindle control board cheap enough.
Then it's just a case of setting VFD params and Mach3 settings.

First let me warn you that the Huanyang drives are very low quality and I've personally had trouble with them and know of others the same.
I would strongly recommend you buy the VFD in UK, also buy a torque vector drive for best performance. The torque vector drive will allow you to run the spindle at lower rpm's and still have some torque left. . . . I can run mine between 4-5K and still be usable.
