RD52.1-5N-400-R-V1-FW/S146

RD52.1-5N-400-R-V1-FW/S146, Bosch Rexroth Indramat, RD 500 Drive Controllers opens new horizons in high-performance AC drive solutions. The RD52.1-5N-400-R-V1-FW/S146 features a Nominal Connecting Voltage of 3 x AC 500 V and delivers a continuous Rated Power of 400 kW. Developed by Bosch Rexroth Indramat, it belongs to the rugged RD 500 Drive Controllers series and is supplied as a Converter without a built-in brake chopper. Integrated liquid cooling with internal pump ensures stable thermal management under sustained loads.

The drive unit incorporates dual RS232 serial interface and RS485 serial interface ports for parameterization and logging, alongside fieldbus support including Profibus connectivity, CANopen connectivity, and Interbus S support. Advanced synchronization is achieved via Peer-to-peer coupling and Synchrolink, enabling coordinated multi-drive operation. An internal fault memory retains up to 10 recent fault entries for streamlined troubleshooting, while the high-contrast graphical display provides real-time visualization of voltage, frequency, and operational status. Modular supply modules and an embedded rectifier facilitate full regenerative mode without external hardware.

Designed for seamless integration into handling machines, conveyor systems, hoist equipment, and process-technology installations, the RD52.1-5N-400-R-V1-FW/S146 excels in demanding industrial environments. Its liquid cooling with internal pump minimizes maintenance compared to fan-cooled units, boosting uptime and reliability. The converter’s flexible interface suite and compact footprint simplify retrofits and expansions, while robust fault-logging and real-time diagnostics reduce commissioning time and life-cycle costs.
