Re: 300W Mitsubishi AC servo motors and drives

Hi Harko,

Thanks, so I will go on with these servo motors and drives.

Have no idea how much mechanical drag my system has, maybe when
climb milling the force will be pretty large. I guess if we use
linear slides (which is not the case here)we could use much smaller
motors and still having high feed rates.

Horace.
