Claim 14:
15. A method for dynamically controlling operation in a slow-down region for a material handling system, the method comprising the steps of:
determining a distance of a bridge or a trolley to travel between a slow-down sensor and a desired position for a slow-down speed;
receiving a feedback signal from the slow-down sensor at a motor controller for the bridge or trolley;
determining a slow-down distance for the bridge or trolley to reach the desired position for the slow-down speed after receiving the feedback signal from the slow-down sensor;
continuing motion of the bridge or trolley without decelerating for at least a portion of the distance between the slow-down sensor and the desired position for the slow-down speed; and
decelerating the bridge or trolley with the motor controller when the bridge or trolley enters the slow-down distance.
