| Title: |
Sensorless Homing System for Stepper Motor System |
| 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.
