Drive motor reversal for a barrier operator or the like
First Claim
Patent Images
1. A method for reversing a direction of movement of a barrier being moved by an electric motor, comprising:
- providing a plurality of reversal algorithms for performing barrier movement reversal, the plurality of reversal algorithms comprising at least a first reversal algorithm and a second reversal algorithm which provides more rapid reversal than the first reversal algorithm;
sensing a request to reverse the direction of movement of the barrier;
identifying a type of request sensed in the sensing step; and
performing one of the plurality of reversal algorithms selected in response to the type of request identified in the identifying step.

Abstract
Methods and apparatus for reversing a drive motor for a barrier movement operator are disclosed. The operator senses the nature of a request for reversal and based on the nature of the sensed request performs one of a plurality of processes to reverse the motor.
