Abstract
A system for moving a barrier includes a motor with an integrated encoder operative to generate pulses as a function of rotation of the rotatable shaft of the motor. A preferred form of encoder is a rotary optical encoder to generate optical pulses as a function of rotational movement of the rotatable shaft. Both a microcontroller to determine door status and a controller to control door movement receive the pulses and separately execute methods in response thereto.
