A motor controller detects the speed at which a driven member is travelling when it enters a slow-down region of a material handling system. Using this speed and a deceleration rate, the motor controller determines a required slow-down distance to reach a desired slow speed. A traverse distance is determined as a difference between the length of the slow-down region the slow-down distance. The traverse distance extends for a first portion of the slow-down region and the slow-down distance extends for the second portion of the slow-down region. While the driven member is located within the traverse distance, the driven member may continue operating at the speed at which it entered the slow down region. When the driven member reaches the slow-down distance, the motor controller begins decelerating the driven member.
