Application class 3 (positioning drive)
In addition to the drive control, the drive also includes a positioning control, so that the drive
operates as a self-contained single-axis positioning drive while the higher-level technological
processes are executed on the controller. Positioning requests are transmitted to the drive
controller via PROFIBUS/PROFINET and launched. Positioning drives have a very wide
range of applications, e.g. the screwing and unscrewing of caps in a bottle filling plant or the
positioning of cutters on a film cutting machine.
