The MS196 is used to control the speed of the feed screw relative to the speed of the main conveyor and overhead belt. It is important in this application that the product velocity exiting the screw precisely matches the conveyor velocity. Machines may now be designed to handle a wider range of product sizes and production rates. When a product change over requires a product pitch (product spacing) change, the operator simply changes the timing screw for the new product and selects the new ratio set point on the MS196. Historically a time consuming pulley or gear change over had to be performed.
