Decentralized control from SEW-Eurodrive, Lyman, S.C. (www.seweurodrive.com), takes advantage of motor-installation provisions in NEC code (Article 430.53 (c))to use fewer branch circuits, which reduces costs and installation time. In some cases, companies save 60% on installation. It also places the controller nearer the motor, which simplifies maintenance. SEW provides all the necessary components, from control cabinets to output shafts. Other advantages include using less space for control cabinets, daisy chaining the power and bus to reduce branch circuits and cabling, and operating on common bus networks, including DeviceNet, CANOpen, Profibus and Interbus, that use less field control wiring.
