DKR02.1-W300B-BE11-02-FW

The Bosch Rexroth Indramat DKR02.1-W300B-BE11-02-FW controller from the DKR Drive Controllers series delivers high-performance motion control with a Bleeder Configuration fully integrated, ensuring safe discharge of DC-link voltage during shutdowns. It features a native Command Interface via SERCOS interface for deterministic, low-latency communication with CNC systems and programmable logic controllers. Thermal management is handled by an efficient Cooling Method employing an air-cooled, built-in blower that maintains optimal operating temperatures under continuous load. The unit’s robust construction aligns with the original Design Version 1 specification, offering proven reliability in demanding industrial environments.

Engineered as part of the DKR product family, this drive controller embeds a Line Series 02 power stage optimized for high-current applications, with a Current Rating of 300 A to handle dynamic torque requirements. The controller accepts both Digital servo and resolver feedback for precise motor synchronization and closed-loop performance. With a Nominal Current of approximately 300 A, it supports heavy-duty axes in milling, turning, and grinding centers without compromising response times. Integrated protection features such as overcurrent detection and automatic de-rating under thermal stress reinforce system uptime and safeguard downstream components.

Installation and commissioning are streamlined by consistent mechanical footprints and standard fan-out connectors, reducing cabinet engineering time. The DKR02.1-W300B-BE11-02-FW’s modular architecture and firmware compatibility across the Bosch Rexroth Indramat lineup simplify software updates and parameter migration. Whether deployed in single- or multi-axis configurations, this controller excels in precision machining, material handling, and automated production lines where high current, reliable cooling, and real-time communication are critical to performance.
