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