RD51.1-4N-110-L-NN-FW/S111

RD51.1-4N-110-L-NN-FW/S111, Bosch Rexroth Indramat, RD 500 Drive Controllers marks the latest generation of AC drive converters designed for heavy-duty industrial motion control. This controller delivers a Rated Power of 110 kW from a Nominal Connecting Voltage of 3 x AC 380-480 V, all while maintaining exceptional precision for synchronous and induction motors. Its modular housing provides IP-level protection against solid contaminants exceeding 12 mm, ensuring robust performance in harsh environments. Integrated firmware supports wide-ranging automation protocols and simplifies integration into existing Rexroth Indramat ecosystems.

Boasting a high-performance 32-bit floating point signal processor, the drive can execute complex control algorithms with minimal latency. A forced air cooling mechanism maintains optimum thermal conditions, enabling continuous operation at a Rated Current of 195 A and enduring Peak Currents up to 390 A for 0.5 seconds without derating. The controller can generate an Output Frequency up to 250 Hz, accommodating high-speed axis applications. Compact dimensions of 405 mm length and 770 mm height minimize cabinet real estate, and the drive is supplied as a Converter without a built-in brake chopper.

Engineers benefit from seamless integration with Bosch Rexroth Indramat’s RD 500 series, leveraging standardized connectors and parameter cloning to cut commissioning time. The robust construction and advanced thermal management deliver high reliability, even under continuous heavy load. Ideal for packaging, printing, and metal-forming lines, the RD51.1-4N-110-L-NN-FW/S111 ensures precise speed, torque, and position control across demanding production environments.
