A company is unable to upgrade its own positioning control system because the components are no longer available. It is not economically feasible to develop a new control system. On the other hand, existing systems have to be retrofitted or defective ones replaced. What to do?

Ferag AG is one of the world’s leading suppliers of machinery and equipment for the print finishing industry. Ferag systems produce up to 100,000 magazines or newspapers per hour. The Ferag machines are "fed" by an almost endless flow of paper coming from a rotary printing press. Each printed sheet is automatically cut, folded, and assembled; each magazine is automatically stitched together. Supplements, like leaflets, flyers and CDs, are inserted and address labels are attached without stopping the fast moving conveyor belts. Download PDF

All humans are very sensitive to the changes in acceleration that can be experienced inside most common lift cabins. Modern control systems enable electric and hydraulic drives to make gentle, almost imperceptible movements. In total, there are four different motion sequences between the starting and stopping of the lift that cause various passenger sensations. These sequences must be handled by the control system using optimized motion patterns and parameters. Download PDF

Apostore GmbH is one of the world's leading suppliers of compact sized storage systems in use by pharmacies and hospitals. The medicine boxes are automatically transferred into the storage system, arranged internally, and dispensed again at the request of the pharmacist. Download PDF

The endless flow of cooled and pressed "ribbon" on the conveyor belt is cut into single mats by "flying saws". The two sawing units are placed on transverse travelling gears. The whole unit is accelerated on a linear guide parallel to the conveyor belt until the speed is synchronized with the conveyor belt and the position of the saw blade corresponds to the requested fiber mat length. The linear speed of the sawing unit is controlled and adjusted every millisecond to match the speed of the conveyor belt during the sawing process. This guarantees that the soft material is not compressed or stretched by the saw blade. Download PDF

A high performance processor technology in conjunction with high-end control algorithms allows to provide high torque levels already at standstill und to react to load cycles in milli seconds.

The zub machine control AG has optimized some innovative control algorithms for an Asian producer of cranes and has succussfully carried out from theorie into practice, i.e. integrated into the internal software of the frequency converter.

Hunkeler AG is one of the world's leading suppliers of compact, stackable system modules for print finishing. Complete paper processing is done between the unwinder module, with its huge paper rolls, and the final device that outputs single pages, magazines and books. The paper moves at speeds of up to 220m/min out of high-speed printers and is perforated, punched, cut, and folded "on-the-fly" inside Hunkeler's system modules. Download PDF

The highly precise position information of inspection machines is generated by different position feedback devices. The motorized movement of the measuring heads is processed and controlled by a modern motion control unit which evaluates all the position feedback signals simultaneously. It is also possible to release the mechanical output shaft of the motors and move the measuring heads manually to a position close to the inspected device. The final micrometer positioning is then done automatically again. Download PDF
