Abstract
A method for referencing a drive position of an electric drive of a gripper half of a production gripper in a closed position of two gripper halves includes closing the open gripper halves, determining multiple actual positions of an electric drive and tracking error values of the electric drive in a time interval during the closing of the gripper halves until beyond a point in time in which the closed position is reached, determining a straight line based on the ascertained tracking error values depending on a related time-tracking-error function, determining the instant of the zero crossing of the straight line of the time-tracking-error function, and determining the actual position of the electric drive that corresponds to the instant of the zero crossing of the straight line of the time-tracking-error-function. A production gripper and a respective control device for operating the production gripper are set up to carry out such a method.
