DKR02.1-W300B-BE11-02-FW
DKR Drive Controllers
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.

Frequently Asked Questions
How does the integrated bleeder configuration affect system safety?
The bleeder safely discharges stored DC-link voltage during shutdowns. This prevents residual energy from damaging components or posing risks to operators.
What type of communication interface is used in the DKR02.1-W300B-BE11-02-FW?
It uses the SERCOS interface, which ensures deterministic timing for CNC and PLC systems. This minimizes latency in motion synchronization across multiple axes.
How does current capacity influence motor performance in this controller?
The 300 A stage enables handling of high torque transients. This makes it suitable for heavy-duty machining tasks with rapid load changes.
What happens if the drive experiences thermal overload?
It automatically de-rates current output to protect internal components. This allows continued operation while preventing overheating damage.
In what way does the standardized footprint simplify cabinet engineering?
Consistent dimensions enable easy replacement or scaling. Engineers can reuse panel layouts without major redesign.
