Classification: CPC B | IPC B

Claim 0:
1. A system for dynamically controlling operation in a slow-down region for a material handling system, the system comprising:
at least one motor operatively connected to the material handling system to drive motion of an axis of motion for the material handling system;
at least one motor controller operatively connected to control operation of the at least one motor; and
a sensor configured to generate a feedback signal corresponding to a start of the slow-down region along the axis of motion, wherein:
the slow-down region has a first length,
the feedback signal is provided to the at least one motor controller, and
the at least one motor controller is operative to:
determine a present velocity of the axis of motion,
determine a slow-down distance for the axis of motion as a function of the present velocity and a deceleration rate,
determine a traverse distance for the axis of motion as a difference between the first length and the slow-down distance,
keep the present velocity of the axis of motion at a commanded velocity when the axis of motion is within the traverse distance, and
decelerate the axis of motion when the axis of motion enters the slow-down distance.
