Mach3 VFD control via Modbus using brain file

[magicniner]

I am actually pretty surprised how little interest there is in both Mach3 brains and the use of RS484 Modbus to control and monitor VFD. It is an industry standard and very common there for a reason.

I suspect many people will shy away from Modbus because the documentation for the cheaper Chinese VFDs is only just adequate to support manual and, if you're lucky 0-10V speed control ;-)
