The Indramat Refu RD 500 Drive System, equipped with R911200194 (RD51.1-4B-001-L-NN-FW) - a converter unit in the RD 51 series, functions for both synchronous and induction motors. This high-performance system includes converters, DC supply inverters, and supply & rectifier modules with regenerative feedback, and is ideal for non-servo operations like pumps, ventilators and moving gears. The unit operates through voltage frequency control with a connecting voltage between 380V and 480V (+/- 10%). Its compact, modular design allows for easy control cabinet mounting, minimizes noise radiation and includes integrated radio interference filters and line reactors. The converter unit can be operated and parameterized using REFUwin software and displays on a removable user panel with a parameter copy function. It also features an integrated brake chopper and firmware compatibility. Meeting the IP 20 protection category, it prevents penetration from external solid objects over 12mm.
