Product Description:
The RD52.1-4B-160-F-F1-FW is a drive controller manufactured by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. It converts three-phase line power into a regulated output for asynchronous or synchronous AC motors, enabling precise torque and speed regulation in automated conveyors, presses, machining centers, and other demanding drive tasks. Its control platform supports applications that require stable acceleration, controlled deceleration, and consistent operation under changing load conditions. The hardware is supplied as design generation 1, which suits established RD 500 system layouts.
It operates from 380 to 480 V utility mains that feed a three-phase AC converter and an intermediate DC link. Under proper cooling, it can deliver up to 160 kW to the connected motor group. Control loops are executed with field-oriented vector control, which regulates flux-producing and torque-producing current components separately for responsive motor behavior. The power section and measurement channels are rated for component deviations of ±10 %, giving the unit tolerance for common grid fluctuations while helping output regulation remain stable.
A built-in brake chopper protects the DC link from overvoltage by switching excess energy into a braking resistor during rapid deceleration. Heat generated by power semiconductors is removed through forced-air cooling with integrated liquid circulation, combining fan-driven airflow with a coolant plate to keep internal temperatures under control during sustained operation. Incoming distortion is reduced by an integrated mains filter, which helps limit conducted interference on the supply side. Diagnostic resolution is improved through current filter feedback signals (U6, V6, W6), allowing the control board to monitor individual phase currents and respond quickly to load changes or phase imbalance.
