Abstract
A constant speed barrier operator comprises a controller, a memory unit, a potentiometer, a pulse counter, and a motor control. The potentiometer and pulse counter monitor the position and speed of an access barrier. As the access barrier is moved between open and closed positions the controller samples the position and speed of the access barrier. These samples are used to analyze whether the speed at a given point deviates from a predetermined speed selected for the access barrier. If a variation exists, the controller takes corrective action by changing power settings for the motor for a given access barrier position.
