Abstract
An automated luminaire and method are provided. The automated luminaire includes a stepper motor, a mechanism moved by the stepper motor, and a control system coupled to the stepper motor. The control system rotates the stepper motor, senses a current passing through a motor winding of the stepper motor, determines from a calculated characteristic of the sensed current that the mechanism has contacted an end stop, and in response, stores data relating to a current position of the stepper motor in a memory of the control system.
