Controls and Drive Technology next page Christian Coy, Dr. Carsten Rebbereh Whether pumping, ventilating, compressing, moving, processing or machining – the machine and plant building industry is demanding automation and drive solutions which are both highly flexible and scalable. Siemens offers all the tools to engineer integrated drive systems that provide answers to these needs. How continuously rising functional diversity can be intelligently managed, demonstrates the example of the efficient sinamics drive family. No matter what the branch of industry, the emphasis today is shifting increasingly towards individual solutions. This tendency is driving ever greater complexity within the production and drive landscape – complexity which requires effective management. One approach to this challenge is the adoption of cohesive, integrated solutions. With its Sinamics drive family, Siemens demonstrates how continuously rising functional diversity can be intelligently managed, permitting efficient project engineering and commissioning. At the same time, steady advances in the development of converters as the key constituent of integrated drive systems provide wideranging potential for even greater energy and resource savings in production – today and in the future. Managing functional diversity and safety Nowadays, in particular using optimized software and firmware, it is possible to implement wide-ranging functionalities within drive systems. Siemens offers a graphic editor for the project engineering of closed and open loop control functions which can be used without prior knowledge of programming. Known as the Drive Control Chart, this provides a clearly arranged depiction of control-specific structures and permits graphic project engineering and extended device functionality using freely available control, calculation and logic modules. 01 Energy-efficient drives from Siemens are used to drive the car body conveyor systems operated in the Martorell Seat parent plant near Barcelona Because of their functional diversity, safety is also becoming an increasingly relevant issue when working with converters. What is called for here are simple, but at the same time flexible systems, with the aim of implementing drives which are safe but which involve the fewest possible additional components. Siemens achieves this objective with its Safety Integrated system, offering broad safety functionality across the whole of the Sinamics spectrum. Its integration has resulted in fewer components and reduced wiring efforts, which in turn make for greater machine availability. The system approach of Safety Integrated is of particular benefit to the costumer as support is provided in the initial system configuration, ensuring that both operating and commissioning concepts remain safe and at the same time easy to work with.
