| Title: |
Systems and Methods for Controlling the Position of a Moving Light Fixture |
| Abstract: |
A moving light fixture and methods for controlling the position of the moving light fixture. The moving light fixture includes a housing, a motor operably coupled to the housing to rotate the housing about an axis of rotation, and an indexer configured to rotate in conjunction with the housing. A magnetic position encoder transmits a first position signal indicating an angular position of the housing, and an optical sensor transmits a second position signal indicating a position of the indexer. An electronic controller receives a target position for the moving light fixture, determines an angular position of the housing based on the first position signal, determines a position of the indexer based on the second position signal, determines a current position of the housing, and drives the motor to move the housing from the current angular position to the target position based on the position of the indexer. |
