Interesting. I nearly acquired a Delta VFD, but the vendor here in Oz was out of stock with no indication of when they would have them - so I bought a Schneider Electric ATV12H075M2 instead. Hopefully the generic driver will work with this too (Schneider apparently being the crowd that invented Modbus). It is as yet uninstalled as I have a way to go yet, although I have (finally) got my steppers turning with some of the sample g-code program's supplied with LCNC.
I will be following this thread with great interest. Cheers, Alex.
