Subject: Re: [Emc-users] how to control lathe spindle with a mesa 7i77 card
just another question for peter
can you just confirm how the 7i77 and 7i77 spindle controls differ please.
and if I connect up a spinx1 board do I need flash a pin file into the 6i25
or should it just work with the stock 6i52x7i77 config regards
andrew
You would need firmware that has a PWMgen on the second 6I25 connector
(5i25_7i77_7i78.bit is one possibility)

hey peter just a quick question on this spinx1 card
this looks just what I need just want to confirm a few things
my fanuc drive takes a 0-10v signal. 10v comes out from drive and it has
a wiper and 0v just like a POT. I know I can use a 7i76 easily to run it.
just checking that the spindx1 is the same idea. I saw reference in the
manual to a 5-18v input voltage from drive. since my input voltage is 10v
am I good to go?
the price is right on that little card and it looks perfect. I might use
a spare 7i76 now with the 7i77 and replace it once make my next order of
mesa cards
regards

Thanks Jon.
I am controlling a 1988 fanuc velocity spindle drive. And no Idea about
isolation. Not keen to try it lol. Really I just want a isolated 0-10v
virtual pot like the Mesa 7i76 has. Otherwise I might daisy chain in a
7i76 just for the spindle io. but that is such a waste lol.
If you have a spare parallel expansion slot, you could use a SPINx1
