the option I just thought of while googling is, can I convert the sin cos format in to a normal TTL or something like that? even 1000 ppr would be heaps it is only on the spindle.
I just want to get the data into the vfd so It knows when the motors is slowing down. and so I can rigid tap and the existing encoder is a high quality heidenhian one so might be good to keep it if it is not too much trouble. regards Andrew On Wed, Feb 12, 2020 at 7:43 PM andrew beck <andrewbeck0...@gmail.com> wrote: > Hi guys > > wondering if anyone has any ideas here. > > I have a heidanhain spindle motor that runs up to 10000 rpm and has a 5v > sin cos encoder on it.
