PLANT MAINTENANCE, TEST + MEASUREMENT

Future-proof Simon Andres, CEO of the retrofit project partner Andres Antriebstechnik AG, says, “The new controller enables significantly simplified machine set-up and saves us time.” And Markus Alaimo, a technician involved with the project at Strausak, adds, “I simply plug the cable into the laptop and enter the IP address – after that, everything’s self-explanatory. And you don’t need to be a drive specialist to commission the drive systems.” Following from the successful machine retrofit, Strausak is already planning further improvements. “Long term, we intend to upgrade all our machines to Siemens components. This will ensure we’re working with an integrated concept and will simplify our warehousing,” says Alaimo.

and drive technology from Siemens. A burnishing machine is fitted with a burnishing disk, a carbide wheel with tiny notches which rotates at between 1 000 and 1 500 revolutions per minute.The notches remove projecting material and the pressure exerted by the disc compresses the surface of the pivot, making it harder and more stable. Safety integrated With the completion of the retrofit, each of the burnishing machine’s four motors is controlled by a Sinamics S120 servo drive system. The four Sinamics converters are linked over the open Industrial Ethernet standard PROFINET to the higher-level Simatic ET 200SP distributed I/O. Like the drive system, this also benefits from its own integrated safety functions. Commissioning is quick and simple using a web server, and Strausak uses a Simatic KP400 Panel for operation.
