The Bosch Rexroth RD51.1-7N-045-L-NN-FW is a universal drive controller. It is deployed with a compatible Bosch motor for industrial and commercial applications. The controller has a modular architecture. Various hardware options are available for RD51 controllers. However additional functions are not available on the RD51.1-7N-045-L-NN-FW controller. Multiple firmware options – that are optimized for different applications – are also available. The controller firmware is ordered as a separate subposition. The RD51.1-7N-045-L-NN-FW controller is based on an inverter that operates at 530 to 670 Volts DC. The inverter does not include a brake chopper. RD51 controllers based on AC converters are also available. Rated motor output of the RD51.1-7N-045-L-NN-FW is 45 kilowatts at 4 kilohertz pulse frequency. Other controller performance data for 4 kilohertz pulse frequency are 82 Amps rated current and 54 kVA rated output.

Performance data for the RD51.1-7N-045-L-NN-FW controller at 8 kilohertz pulse frequency are 37 kilowatts rated motor output, 68 Amps rated current and 45 kVA rated output. The controller is designed for forced air cooling. The specified minimum air flow rated for proper heat dissipation is 0.2 m³/s. Size class of the RD51.1-7N-045-L-NN-FW controller is C and it is available in an IP20 rated housing. Weight of the controller is approximately 22 kilograms. The working temperature range is 0 to 40 degrees Celsius. Bosch has provided radio interference suppression filters on the controller to reduce harmonics fed back into the line supply. Commissioning of the RD51.1-7N-045-L-NN-FW controller is done through an operator panel with graphical display or a PC with RDwin software package. Bosch has designed the controller for simple handling through automatic motor handling with parameter identification. The controller and associated equipment should only be installed by trained personnel. This product can be shipped globally with a one year warranty period from Wake Industrial.
