RD52.1-4B-022-L-V1-FW

The Bosch Rexroth Indramat RD52.1-4B-022-L-V1-FW from the RD 500 Drive Controllers series is a high-performance drive converter engineered for demanding industrial applications. This RD52.1-4B-022-L-V1-FW unit operates on a Nominal Connecting Voltage: 3 x AC 380-480 V and delivers a Rated Power: 22 kW output while drawing an Input Current: 43 A at full load. Built with a robust Unit Type: Converter with a built-in brake chopper, it precisely regulates both synchronous and induction motors in servo systems. The controller meets the IP20 protection class standard and features a Cooling Mode: forced air cooling system designed to maintain optimal thermal performance under continuous operation.

Reliability is reinforced by integrated heat dissipation and low acoustic emissions, allowing uninterrupted operation without excessive noise. The forced air cooling mechanism channels airflow efficiently across power electronics to prevent overheating and maintain stable switching performance. A built-in brake chopper protects against regenerative energy, while grounding requirements and radio interference suppression measures ensure compliance with EMC directives. With a compact footprint and durable housing, this drive withstands harsh factory environments and reduces downtime through simplified preventive maintenance.

Integration is seamless via multiple communication links: SERCOS interface, Profibus interface, Interbus interface, and CAN bus interface provide flexible control and parameterization options. Operators can monitor real-time drive status, adjust motor profiles, and log performance data using standard industrial networks. Proper installation—including secure grounding and optional suppression devices—ensures safe operation and minimizes electrical noise. The RD52.1-4B-022-L-V1-FW is ideal for metal forming, food processing, paper converting, and other machinery requiring precise motor control and robust converter performance.
