I have a 20BA150FFWBO servo amplifier made by Sanyo Denki.
It is the drive for the spindle of my TC-225 Tapping center. The original control has been removed from the machine so I need to make a new one, but unfortunately I'm not familiar with the analog amplifiers.
So what is the method to set or control the orinetation of the spindle in case of analog amps?
Any help would be great!
