...0-5 volt potentiometer feedback for position control of an actuator (servo) with a potentiometer. I want to switch to using a stepper motor control and stepper motor position as a 0-5 volt position signal. I believe the attached PDF document describes what I need in detail. I tried using the Leadshine DM805-AI from automationdirect.com. It worked with some limitations. I developed a "limit" circuit to limit the travel of the stepper so as not to damage the position sensing pot if I needed more than a 1 turn pot, which I often do. The stepper had to be prevented from taking the pot beyond its limit of turns. Another downside of this solution is the stepper motor got quite hot because of the dithering trying to hold a setpoint with the pot feedback. Another is the possi...
