More and more applications require higher dynamics of the z-axes, which cannot be achieved with conventional spindle-driven axes. However, the use of direct linear motors in compact vertical axes presents some challenges.
Despite maximum care during production and in the selection of components used, systematic errors can occur in a system. These can have a variety of causes, for example the accuracy of the encoder scale used, the straightness of the rails or the perpendicularity of the axes to each other.
For particularly high requirements, the control offers the possibility of compensating for systematic errors and thus achieving the highest accuracy requirements.
