Abstract
Controlling a distance between a first sprocket and a second sprocket in a conveyor. The control includes receiving a first signal from a first sensor related to an angular position of the first sprocket, determining a value for an angular position of the first sprocket based on the first signal, receiving a second signal from a second sensor related to an angular position of the second sprocket, determining a value for an angular position of the second sprocket based on the second signal, determining a relative difference in phase between the angular position of the first sprocket and the angular position of the second sprocket, and determining an amount of excess chain in the conveyor based on the relative difference in phase between the angular position of the first sprocket and the angular position of the second sprocket.
