21 to 25 April Motion control: Efficient production processes ... utilizing the latest automation technology can save users a lot of money HANNOVER MESSE 2008, * Special display "Energy Efficiency in Industrial Processes" showcases * Fitting frequency converters to pumps can save users tens of thousands * Modular systems are the key to simpler processes . "Motion control" refers to the use of modern drive devices and automation techniques to control machine movements in mechanical and plant engineering applications. In other words, intelligent, network-integrated drive units are now taking over from mechanical production processes. At HANNOVER MESSE 2008 all the latest motion control products will be on display in Halls 14 and 15 at the trade show Factory Automation. The real benefits of motion and drive control are ultimately commercial ones: machine operation is optimized, making production processes more efficient and controllable - and saving the user a lot of money in consequence. Changeover times are cut, wear and tear on parts is reduced along with servicing costs, production programs are more flexible - and energy consumption falls. In fact, automation systems as we know them today are scarcely conceivable without effective motion control. In Hall 14 the German company Control Techniques will be exhibiting their latest three-phase, DC and servo drives under the collective heading "Energy-saving drive systems". These are used right across the industrial spectrum. Frank Borchardt, head of marketing at Control Techniques, elaborates: "We offer drive solutions for all types of machinery. Some of the areas in which we specialize are textile machines, elevator systems, woodworking machines, food-processing machinery and test rig systems, particularly for the car industry. We supply complete systems solutions for our customers, with a strong emphasis on energy saving and energy recuperation systems." Substantial savings to be made Based in Hennef near Bonn, Control Techniques is contributing to the special display "Energy Efficiency in Industrial Processes" in Hall 6 and showing how the fitting of frequency converters to pump motors can save energy. Frank Borchardt explains: "We have joined forces with a systems partner to equip hydraulic pumps in an aluminium works with frequency converters." The venture has proved successful: the user now saves on production costs. As Borchardt points out: "The savings in running costs amount to thousands of euros a year for each pump motor! Which means that automated systems of this kind can effectively pay for themselves within two years." Going flat out all the time wastes valuable energy As a rule of thumb, when motors are connected direct to the grid, they are usually wasting energy. Borchardt explains: "It's like driving your car flat out the whole time. When you are going downhill, though, you don't drive flat out but apply the brakes. We provide intelligent solutions that recycle the braking energy back into the grid." Highlights on the stand of Control Techniques (Hall 14, Stand H 44) include: the new Digitax ST servo regulator for servo applications that call for high peak torque, dynamic response, user-friendly operation and flexible integration functionality; the SM EtherCAT module, the fastest real-time bus for use in Ethernet applications; and the new Affinity frequency converter for energy-saving solutions in building automation - as incorporated, for example, into complete heating, air-conditioning and ventilation plants for supermarkets or hospitals. Modular systems make for easier procurement, project management and commissioning of automation solutions On the Rexroth stand (Hall 14, Stand H06) the prize exhibit - and indeed a highlight of the whole motion control coverage - is the Rexroth Automation System, which offers not only technological benefits but also commercial gains. According to the manufacturer, this comprehensive solutions toolkit enables the user to extract the maximum potential from all drive and control technologies by simplifying the procurement, project management and commissioning of automation solutions. The achievable savings can be as high as 25 per cent. MPC (memory programmable controller) - also known as PLC (programmable logic controller) - is the magic word here, since the standardized MPC combined with open interfaces inside the Rexroth Automation System simplifies the integration of drive motors, functional modules and controllers in automation environments. Here too, as in all other areas of HANNOVER MESSE 2008, energy efficiency plays a key role. Energy efficiency is a major issue for the future Dr. Karl Tragl, head of sales for Bosch Rexroth AG, looks at the bigger picture: "Improving energy efficiency is often said to be one of the most important issues for the future. As far as Rexroth is concerned, the future has already begun. Specific measures can be put in place today using technologies that are already available. It pays to think about individual measures, while also working to optimize complete systems. We have reached a point where significant advances in energy efficiency can be affordably achieved through a combination of different drive and control technologies. Rexroth offers products and solutions for all types of drive and motion control technology - both specialized and integrated. Our customers and partners are already reaping the benefits today. Together we can achieve even more by concentrating on increasing energy efficiency at every stage of the industrial manufacturing process."
