Re: AC servo motor

Hi Randy,

Thanks. I wonder why don't gecko develop low cost drives for AC
servos. Is it because drives and AC servos are already a combo sold
by Yaskawa etc.,so there no such chance for gecko to do so.

And one more thing, is Mach 3 compatible with AC servos ? Sorry if I
had asked silly questions, I am an idiot in electronics.

Horace.
