Drives Family on One Platform

“Our customers are asking us to help them meet faster time-to-market, greater productivity and increased manufacturing flexibility,” noted Aubert Martin, president of Siemens Energy & Automation (www.sea.siemens.com), as he presented Sinamics, a family of AC drives that operate on a standard platform.

Sinamics users can select, start up and configure the correct drive for their applications at any power range from 120 watts to more than 1 Megawatt with the same software. As a result, manufacturers can streamline simple and complex multi-drive manufacturing operations.

“With Sinamics, Siemens has made a tremendous investment in the next generation of drives technology,” continued Martin. “We’ve spent a significant amount of time and resources over the past several years researching and developing this product line, which builds upon expertise from Siemens worldwide and defines our commitment to bringing the latest innovations to U.S. businesses.”

Common engineering tools, “Sizer” and “Starter,” select and configure any drive solution available, from basic variable frequency drives to complex motion control. The actual Sinamics drives family consists of G and S models. The G drives are designed for general to high-performance, stand-alone drives applications. The S drives take a unique approach to coordinated drives with servo functions.

The S120, for example, can operate in vector or servo control modes, making it ideal for printing, packaging, converting, plastics and paper industries. The S150 high-performance enclosed drive is quiet and compact with active controls for stable operation, even under poor supply system conditions. An enclosed drive, it is rated for 150 to 1,250 horsepower, 400 to 480 volts and 1,500 horsepower, 660 to 690 volts.
