RD52.1-4N-011-L-NN-FW

RD52.1-4N-011-L-NN-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers form a high-performance drive control solution optimized for industrial automation. The RD52.1-4N-011-L-NN-FW converter without a built-in brake chopper is engineered by Bosch Rexroth Indramat for the RD 500 Drive Controllers series to precisely regulate motor speed, position, and torque. It accepts a nominal connecting voltage of 3 x AC 380-480 V and delivers a continuous rated power of 11 kW via its robust three-phase interface. Encased in an IP20 protection class housing, the unit is designed to withstand ingress of solid particles and ensure long-term operational stability.

The drive’s core technical_specs include a forced air cooling mode that maintains optimal junction temperatures under heavy load and an input rated current of 25 A with an overload capacity of 200%, enabling handling of transient currents up to 60 A without tripping. The converter supports both synchronous and induction motors, providing seamless integration with a wide variety of industrial equipment. Designed to accept input voltages between 380 to 400 V, the compact controller delivers precise current regulation and advanced pulse-width modulation for reduced harmonic distortion. Unit type designation as a converter without a built-in brake chopper simplifies system design when external braking modules are already in place or not required.

Installation is simplified by an ambient operating window of 0 to 40 °C and a maximum installation altitude of 1000 meters above sea level, ensuring reliable performance in diverse environments. The RD52.1-4N-011-L-NN-FW seamlessly integrates into existing Rexroth motion control architectures, enabling centralized diagnostics and parameter cloning. Its high overload headroom, robust IP20 enclosure, and efficient cooling scheme deliver exceptional uptime, making it ideal for packaging lines, food-processing machinery, assembly systems, and other demanding industrial applications.
