Abstract
A powered gate operator includes an electric motor coupled by a drive train to a movable gate in order to drive the gate between opened and closed positions. The gate may also be moved manually between these opened and closed positions, or may be moved by powered operation of the gate operator under manual input control of velocity and acceleration of the gate. The gate operator includes a control system with a learning mode allowing a human to move the gate either manually or under powered operation with manual control, and during which the control system learns desired accelerations, deceleration's, pauses, etc., along with start and finish positions for the gate movement in each direction of movement for the gate between opened and closed positions. Thereafter, during powered operation of the gate by the operator the desired movement profile taught by a human to the operator during a learning mode experience is replicated. In the event that no preferred gate movement profile is available to the gate operator from a learning mode experience, it uses a default gate movement profile. Various default profiles of gate movement may be stored in memory and may be selected by an owner o…
