摘要： In one aspect, a movable barrier operator system is provided that includes a motor configured to turn a drum to pay out a cable from the drum and permit a door connected to the cable to move from an open position toward a closed position. The system includes a memory configured to store an expected variable of the door, and a sensor configured to detect movement of the door. The system further includes a processor circuit operatively coupled to the motor, the memory, and the sensor. The processor circuit is configured to: use the sensor to estimate an actual variable of the door; determine whether the actual variable is acceptable based at least in part on the expected variable and the processor circuit causing the motor to turn the drum; and change operation of the movable barrier upon the actual variable of the movable barrier being unacceptable.
