Referencing: Referencing machine's mechanical systems

After being switched on, the majority of packaging machines do not receive feedback on the absolute position of their mechanical systems. Referencing is therefore necessary in order to adjust the axes of the measuring systems and the positions of the mechanical systems. Referencing is concluded when the reference switch is tripped by the mechanical system. Due to the fact that the positioning accuracy of the machine also depends on the referencing, in this case we recommend the use of inductive sensors.
