RD52.1-4B-001-L-NN-FW

RD52.1-4B-001-L-NN-FW, manufactured by Bosch Rexroth Indramat, is a member of the RD 500 Drive Controllers series and delivers precise control for industrial motor applications. This drive converter accepts a Nominal Connecting Voltage of 3 x AC 380-480 V and provides a Rated Power output of 1 kW through its integrated power stage. Equipped with a built-in brake chopper, the Converter with a built-in brake chopper unit supports regenerative feedback, returning braking energy to the supply. A forced air cooling mechanism ensures thermal stability under continuous operation.

The controller’s communication capabilities include dual serial ports: RD232 serial interface and RD485 serial interface, along with support for industrial fieldbuses such as Sercos, CANbus, Interbus S, and Profibus DP. Menu-driven prompts simplify offline setup via PC using the RDwin software environment, allowing rapid parameterization and visualization. High-quality interference suppression filters attenuate electromagnetic disturbance pulses and harmonics fed back into the line, ensuring compliance with EMC standards. Flexible multi-block programming features include logic gates, function blocks, and a technology controller for sequence and motion tasks.

Engineered for seamless integration into existing automation infrastructure, the RD52.1-4B-001-L-NN-FW fits standard control cabinets and mounts easily using its modular supply modules. Its robust design, including rear-mounted power dissipators, delivers reliable operation even in demanding factory environments. With global shipping and a one-year warranty, this drive controller offers dependable performance and simplifies commissioning and maintenance across a wide range of synchronous and asynchronous motor installations.
