RD52.1-4B-055-D-V1-FW

The RD52.1-4B-055-D-V1-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers module delivers robust AC-to-DC conversion with a Nominal Connecting Voltage of 3 x AC 380–480 V and a Rated Power of 55 kW. Its compact footprint houses a Converter with a built-in brake chopper and an integrated Radio Interference Suppression Filter, ensuring harmonic reduction back to the supply. An onboard Line Reactor and EN 50082-2 compliant Noise Immunity safeguard sensitive electronics from supply disturbances. The universal three-phase design supports both synchronous and induction motors, making it ideal for diverse industrial applications.

Designed for high-performance motor control, the RD52.1-4B-055-D-V1-FW features a Torque Rise Time of 0.3 ms and a Current Cycle Time of 0.1 ms, enabling rapid dynamic response. Its Overload Capability peaks at 200 % for 0.5 s and 170 % for 1 s, handling transient loads without derating. The drive supports external 24 V Stand-by Power on X83 for off-line parameterization and fieldbus operation even when AC mains are off. A user-replaceable GUI panel provides real-time status, fault logging, and peer-to-peer Synchrolink communication for multi-drive synchronisation. The Cooling Mode employs a plug-through cooler design, maintaining optimal junction temperatures across an ambient range of 0 … 40 °C, with a maximum survival threshold at 50 °C.

Engineers will appreciate the seamless integration of safety and communication: built-in short-circuit protection, configurable fieldbus interfaces, and removable parameter memory minimize downtime. The RD52.1-4B-055-D-V1-FW’s proven reliability under EN 50082-2 immunity tests and its global one-year warranty underscore Bosch Rexroth Indramat’s commitment to uptime. Whether controlling conveyor drives, pumps, or high-precision gantries, this drive controller delivers precision, robustness, and scalability across modern automated systems.
