I have, on my mill, a 3 phase spindle motor on a VFD, driving the spindle
with a VS belt.
I also have an encoder on the spindle.
I wonder if, for any kind of a yet-unknown purpose, I would want to orient
my spindle in a particular way with precision.
If I did want that, could I buy some kind of

It nearly works with my very basic 1980s VFD. I think it would work a
great deal better with a modern flux-vector drive (and I t
its a very tricky question to answer as depends how dynamic you want or
need it.
we used a standard Hz mode VFD to control a CNC spindle motor as Flux
Vector has a limit of 4000rpm on our VFD so had to use Hz mode to get to
6000+

Robert, would you show some examples of such drives, so that I know what to
look for? Thanks!

Hi Kirk,
That looks really snazzy. One thing to note is that the ModIO can work as
a RS-232 to RS485 converter as well, so you can daisy chain other Modbus
devices such as a VFD or more ModIOs, etc.
On the Engineering notes page is EN007 which depicts the jumper setting
for utilising the ModIOs o
