Two axis stepping motor controlling X/Y shutters. Potentiometer feedback gives absolute positioning on power up. A special analogue feedback control system was used in this application as encoders were not compatible with the rotation environment. The analogue error signal was then converted to a pulse command for stepper positioning.
