Abstract
A method for moving a shearbar (102) towards a fixed stop (109), wherein the method comprises the steps of; energizing a bidirectional motor (110/112) for driving a guide screw (106/108) to move the shearbar towards the fixed stop (109), monitoring a variable indicative of the torque or force output of the motor (110/112), limiting the torque or force output to a first maximum value, moving the shearbar (102) against the fixed stop (109) and stalling the motor (110/112) thereby, deenergizing the motor (110/112), when the resulting torque or force output reaches or exceeds the first maximum value; and energizing the motor (110/112) for moving the shearbar (102) in the opposite direction, away from the stop (109), while not limiting the torque or force output or while limiting the same to a second maximum value, which is substantially larger than the first maximum value. This method can be used in an automatic shearbar adjusting routine, wherein it is not required to rely on limit switches for precluding stalling of the motors (110/112) when the shearbar (102), engages the stop (109).
