The Bosch Rexroth REFU 500 series introduces an innovative three-phase current drive system, specially designed for numerous synchronous and induction motors. With a hardware and software modular design, customization for specific drive tasks is achievable. One example is the RD 51 series R911200242 (RD51.1-4B-007-D-NN-FW) converter that uses a frequency control basis function, controlled by a set value to determine the output frequency. Interfaces like Interbus S remote bus, Profibus DP slave, CAN open, and Peer-to-Peer with fiber-optic cable are available for operation and analysis. Integrated radio interference suppression filters and line reactors minimize feedback harmonics into the line supply, to align with the EMC Directive on noise immunity and emission. This converter boasts a 7.5kW motor output, utilizing a supply voltage between 380V and 480V. It has an IP 20 protection class according to EN 60529, adding protection against dust and objects over 12mm, and its maximum installation height is up to 1,000m above sea level.
