RD52.1-4N-001-L-V1-P1-NN-FW

The RD52.1-4N-001-L-V1-P1-NN-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers form a high-performance AC drive converter tailored for precision motor control. This compact unit integrates seamlessly into industrial cabinets and delivers a Rated Power of 1 kW from a Nominal Connecting Voltage of 3 x AC 380-480 V ±10 % across three phases. Featuring a Unit Type as a converter without built-in brake chopper, it supports field-oriented regulation for smooth torque and speed response. A dedicated standby supply of 24 V ensures residual control logic remains active during mains interruptions.

The drive’s thermal management relies on robust forced air cooling, maintaining stable operation over ambient temperatures of 0 … 40 °C and surviving storage down to -25 … 70 °C with up to 90 % relative humidity (no condensation). Communications are handled via an integrated PROFIBUS-DP interface, while a switchable pulse frequency of 4/8 kHz optimizes motor noise versus dynamic response. Its IP20 enclosure and 3K3 environmental classification permit mounting at up to 1000 m ASL, and the compact package weighs only 6.5 kg in a size class A footprint. The three-phase voltage tolerance of ±10 % ensures resilience to line fluctuations, and an ambient RH rating of 90 % supports challenging factory conditions.

Engineers benefit from straightforward integration of the RD52.1-4N-001-L-V1-P1-NN-FW into larger automation systems, leveraging its standardized PROFIBUS-DP connectivity for rapid uptime. The robust cooling and environmental specs deliver reliable performance in food processing, hoist technology, and assembly line applications. By combining precise control with Bosch Rexroth’s proven platform, the drive ensures long-term durability and minimal downtime across diverse industrial installations.
