RD52.1-4B-160-F-NN-NN-NN-FW

The RD52.1-4B-160-F-NN-NN-NN-FW, manufactured by Bosch Rexroth Indramat, belongs to the robust RD 500 Drive Controllers family. This high-performance converter is designed for heavy-duty industrial use, delivering a continuous 160 kW output at a nominal connecting voltage of 3 x AC 380-480 V. As a converter with a built-in brake chopper, it incorporates an integrated mains filter and chopper stage to manage regenerative energy seamlessly. The drive’s forced air cooling with integrated liquid circulation ensures sustained performance under demanding loads.

Incorporated on the logic and control board are standard serial interfaces—RS-232 and RS-485—for straightforward parameterization via the RDwin PC user interface or a user panel. Optional interface cards extend connectivity with Interbus S, CAN bus, and SERCOS networks for multi-axis synchronization. The unit thrives within an ambient operating temperature range of 0 … 40 °C and can withstand peaks up to 50 °C with a controlled derating of 2.5 % per °C above the nominal limit. Elevations exceeding 1 000 m also invoke output derating to preserve reliability, while long-term storage down to –25 … 70 °C maintains drive integrity for up to two years.

Engineers benefit from seamless integration with Bosch Rexroth’s automation platforms, leveraging plug-and-play user panels and intuitive PC tools to accelerate commissioning. The rugged thermal management and built-in safety features minimize downtime and simplify maintenance in harsh environments. Ideal for process control, material handling, and machine tool applications, the RD52.1-4B-160-F-NN-NN-NN-FW drive delivers reliable, high-density power in a compact footprint.
