RD52.1-4B-055-L-NN-NN-NN-FW

The Bosch Rexroth Indramat RD52.1-4B-055-L-NN-NN-NN-FW from the RD 500 Drive Controllers series is a high-performance AC drive converter designed for rigorous industrial applications. It operates on a Nominal Connecting Voltage of 3 x AC 380-480 V and delivers a Rated Power of 55 kW, providing robust energy to synchronous and induction motors. This unit features a Converter with a built-in brake chopper to support regenerative braking and maintain energy efficiency during deceleration. All critical electronics are maintained at optimal temperatures using a forced air cooling system that ensures continuous operation under heavy loads.

Integrators will appreciate the device’s modular design, which allows seamless adaptation via modular hardware and software configuration. The built-in brake chopper module supports regenerative energy recovery, reducing wear on mechanical brakes and enhancing overall system efficiency. The drive’s I/O architecture provides standard logic interfaces including RS 485 and RS 232, with options for Sercos, CAN bus, Profibus DP, and Interbus S available for expanded network connectivity. A front-mounted operator panel and parameter monitor display real-time voltage, frequency, and a fault memory storing up to ten recent events, streamlining troubleshooting and maintenance.

Commissioning is accelerated using the RDwin PC user interface, while quick setup functions—such as automated motor adaptation and customizable ramp-up/ramp-down profiles—enable rapid deployment. The compact footprint and standardized mounting dimensions make the unit easy to integrate into existing control cabinets, and the robust design meets global shipping standards with a one-year warranty provided by Wake Industrial. The RD52.1-4B-055-L-NN-NN-NN-FW delivers precise positioning control and reliable performance, making it an ideal choice for complex motion-control systems.
