RD52.1-4N-315-R-V1-FW

RD52.1-4N-315-R-V1-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers opens the door to high-performance vector control for heavy-duty industrial applications. This field-oriented drive converter delivers precise motor regulation while conforming to industry standards and safety protocols. Featuring removable firmware modules and an integrated parameter memory, it ensures quick commissioning and minimal downtime. Robust construction and clear status indicators streamline diagnostics in demanding environments.

Incorporating liquid cooling with internal pump technology, the drive maintains optimal thermal performance even under continuous full-load operation. It accepts a nominal connecting voltage of 3 x AC 380-480 V (±10% tolerance) and provides a rated power output of 315 kW without derating. A built-in brake chopper handles regenerative energy up to its design limit, while the 24 V standby power interface supports smooth control logic retention. Operating at a fixed switching frequency of 8 kHz, the unit achieves low acoustic noise and minimal harmonic distortion. The converter’s size class H housing meets environmental class 3K3 (DIN IEC 721-3-3) requirements and tolerates ambient temperatures from 0 °C to 40 °C.

Designed for seamless integration into custom machinery, the RD52.1-4N-315-R-V1-FW pairs with higher-level automation controllers via standard interfaces. Its compact footprint and front-service access reduce cabinet space and simplify maintenance intervals. The rugged electronics and liquid-cooled power stage deliver reliable operation in continuous-duty processes, making it an ideal solution for pump drives, compressors, extrusion lines, and large conveyor systems.
