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

RD52.1-4B-055-W-V1-FW by Bosch Rexroth Indramat in the RD 500 Drive Controllers family delivers high-performance AC drive conversion for industrial servo systems. This model employs liquid cooling to maintain optimal thermal management while supplying a Nominal Connecting Voltage of 3 x AC 380-480 V across three phases. With a Rated Power of 55 kW, the unit integrates a Converter with a built-in brake chopper to handle dynamic braking loads efficiently. Its compact design and robust electronics make it ideal for demanding applications in paper converting, food processing, and assembly automation.

Featuring a sophisticated 32-bit floating point Signal Processor, the controller achieves precise motor control and rapid response in high-dynamic environments. The Overload Capability (0.5 s) of 200% and Overload Capability (1 s) of 170% provide headroom for torque spikes without tripping. Operators interact through a dedicated User Panel with an intuitive display and pressure-sensitive keys for parameter entry and real-time diagnostics. Additional technical highlights include the built-in brake chopper, the compact footprint of the drive electronics, and a factory-tested Cooling Mode set to liquid cooling for enhanced reliability. A global Warranty Period of 1 year underscores the manufacturer’s commitment to quality.

Engineered for seamless integration into Rexroth’s automation ecosystems, the RD52.1-4B-055-W-V1-FW ensures compatibility with established fieldbus networks and PLC controllers. Its liquid-cooled architecture and overload tolerance guarantee continuous operation under peak loads, reducing downtime and maintenance cycles. This drive controller’s modular configurability and proven reliability make it an excellent choice for complex, high-availability industrial processes.
