Method for automatically determining the biting point of a clutch by teach programming

摘要

The method involves regulating a speed of an electrical machine towards a set-point speed, and regulating the speed of the machine towards a null valve when the speed of the machine attains the set-point speed. A deceleration of the speed of the machine is memorized, and a clutch is progressively closed, so that resistive torque is transmitted to the machine for disturbing the speed of the machine. The position of an actuator of the clutch is stored when the variation in the deceleration of the speed is larger than threshold value, where the position corresponds to a biting point.
