Drive solutions with ASi-5
AS-Interface (ASi) has long been an established feature of drive control. This is where the advantages of the globally standardized wiring system are especially conspicuous: the simplest installation thanks to the piercing technology, free selection of topologies, high flexibility and low costs. For many years Bihl+Wiedemann has been offering the ideal drive solution for many different applications – including roller drives, AC drives with and without frequency converter, as well as for 24 V motors. Our range of solutions is focused on leading manufacturers such as Lenze, SEW-Eurodrive, Itoh Denki, Interroll, NORD DRIVESYSTEMS and RULMECA. We also develop custom ASi solutions on request.
