A method to set up at least one movable operating member (5, 7) of an automatic machine for manufacturing consumer articles; the method comprises the steps (16, 17) of: defining a first motion profile of the movable operating member (5, 7), through which at least one processing of the articles is to be performed; and defining a corresponding second motion profile of an electric actuator system (8, 9), which, through a motion transmission system, is mechanically connected to the movable operating member (5, 7) and moves the movable operating member (5, 7) with the first motion profile; characterized in that the method comprises the steps of: determining possible imperfections in the processing of the articles caused by the movable operating member (5, 7); correcting, by means of an interface device of the automatic machine and based on the possible imperfections in the processing of the articles, the first motion profile, thus obtaining a first changed profile of the movable operating member (5, 7); calculating, through a control unit, a reverse kinematics of the first changed profile of the movable operating member (5, 7) through the motion transmission system so as to obtain a second changed second profile to be commanded to the electric actuator system (8, 9); identifying one or more knots of the first motion profile; said knots being changeable by means of the interface device; defining a tolerance interval to limit the change of each knot; in particular, the tolerance interval comprises an upper limit and a lower limit. defining a first motion profile of the movable operating member (5, 7), through which at least one processing of the articles is to be performed; and defining a corresponding second motion profile of an electric actuator system (8, 9), which, through a motion transmission system, is mechanically connected to the movable operating member (5, 7) and moves the movable operating member (5, 7) with the first motion profile; characterized in that the method comprises the steps of: determining possible imperfections in the processing of the articles caused by the movable operating member (5, 7); correcting, by means of an interface device of the automatic machine and based on the possible imperfections in the processing of the articles, the first motion profile, thus obtaining a first changed profile of the movable operating member (5, 7); calculating, through a control unit, a reverse kinematics of the first changed profile of the movable operating member (5, 7) through the motion transmission system so as to obtain a second changed second profile to be commanded to the electric actuator system (8, 9); identifying one or more knots of the first motion profile; said knots being changeable by means of the interface device; defining a tolerance interval to limit the change of each knot; in particular, the tolerance interval comprises an upper limit and a lower limit. determining possible imperfections in the processing of the articles caused by the movable operating member (5, 7); correcting, by means of an interface device of the automatic machine and based on the possible imperfections in the processing of the articles, the first motion profile, thus obtaining a first changed profile of the movable operating member (5, 7); calculating, through a control unit, a reverse kinematics of the first changed profile of the movable operating member (5, 7) through the motion transmission system so as to obtain a second changed second profile to be commanded to the electric actuator system (8, 9); identifying one or more knots of the first motion profile; said knots being changeable by means of the interface device; defining a tolerance interval to limit the change of each knot; in particular, the tolerance interval comprises an upper limit and a lower limit.
