The Bosch Rexroth MPN R911200648 (RD51.1-4N-011-L-CF-FW) is a converter from the REFU 500 drive series, engineered for applications in chemical, process technology, and assembly systems. It features a modular hardware and software architecture. The device supports U/f curve control, delivering a speed precision of 2% and a speed range of 1:20 without requiring an encoder, utilizing slippage compensation. It operates at a nominal voltage of 3 x AC 380 to 480 V (±10%) with a rated power of 11 kW. Output frequency is determined by set values, and an operator panel is provided for monitoring and parameterization. Integrated radio interference suppression filters and line reactors ensure compliance with EMC noise immunity and emission standards. Cooling is achieved through forced air for units rated at or above 110 kW. Connection options include interfaces for RZC01.1-XN and external 24 V stand-by power.
