The Bosch Rexroth R911203157 (RD51.1-8N-045-L-LV-FW) is a drive controller designed for U/f curve control operation. It functions as a 700 VDC ±10% nominal voltage inverter and supports a rated power output of 45 kW. The modular hardware and software architecture is compliant with EMC standards for noise emissions and immunity. The unit does not include a built-in brake chopper and is designed with forced air cooling. Dimensions and installation requirements are classified under size C, with a mass of 36 kg. The device provides external 24 V standby power, adheres to radio interference level A1 per EN 55011 and EN 61800-3, and should be stored in clean, dry environments. Operation above 1000 m altitude may result in reduced performance. Installation must be perpendicular to level surfaces, and thermal management should be considered near heat-sensitive components.
