I have gotten the bug to start work on an old MicroStar N1 lathe.
It has an old Fanuc system 5 controls on it. (1979 vintage) The spindle motor is a 7.33 hp dc drive. It is big at least 18" long about 8" diameter.
I haven't dug into the servos yet to see exactly what I've got, they are DC but that is all I am sure of.
Do you think I should try to get the existing spindle drive to run or replace it with something else? Do you have any ideas on what type of drive to use on it?
What would you use for the servo motors? They are big about 6" diameter 10-12" long. I would guess 3hp or more.
Any documents on this would be nice also, Ha Ha wishful thinking. I have scoured the web and find nothing. Even Fanuc System 5 information is scarce.
