I have some Mitsubishi servo's I picked up a couple of years ago when Mitsubishi US was dumping their old stock of spindle motors,servo motors and VFD's for a song.
The servo's I have left over I believe use a similar feedback as Fanuc now use, some of these encoders have a resolution of 1,000,000p/rev. and are transmitted to the Drive in a serial fashion. There is only 4 signal lines for enc. and commutation.
I assume it is some proprietary method.
