Abstract:
A method for use with a motor controller for controlling a motor and an associated conveyor belt to essentially eliminate obstructions on the belt, the controller driving the motor and monitoring motor load, the method comprising the steps of:(a) monitoring motor load;(b) comparing the monitored motor load to a threshold load;(c) where the monitored motor load is equal to or exceeds the threshold load, driving the belt according to a clearing process calculated to clear swarf;(d) wherein the controller is programmed with a predetermined number which is the number of clearing processes which is likely to clear an obstruction, the method further including the steps of repeating steps (a)-(c), counting the number of clearing processes performed, comparing the number performed to the predetermined number and, when the number performed equals the predetermined number, modifying belt control.
