DKR02.1-W300N-BE11-02-FW

The DKR02.1-W300N-BE11-02-FW, manufactured by Bosch Rexroth Indramat and part of the DKR Drive Controllers series, delivers precise DC bus regulation and advanced servo control in a compact footprint. This drive controller supports the industry-standard SERCOS interface for deterministic communication, ensuring tight integration with automation networks. Designed for demanding motion control, the unit features Digital servo and resolver feedback to maintain high-precision torque and speed performance under dynamic load conditions. Built on the robust DKR product family architecture, this controller provides a unified platform for multi-axis systems.

At its core, the DKR02.1-W300N-BE11-02-FW is rated for a Current Rating of 300 A with a Nominal Current of Approx 300A, supporting heavy-duty motor drives without compromise. The Bleeder Configuration: No bleeder / Without brake chopper, rigid DC bus design eliminates the need for external resistor assemblies, simplifying cabinet layout and reducing component count. Thermal management is handled by an Air (built-in blower) cooling method, which maintains optimal junction temperatures during continuous operation. The unit’s communications rely on a mature SERCOS interface, while the internal electronics adhere to Design Version 1 standards for proven reliability. Organized under Line Series 02, this controller offers straightforward integration into existing DKR line systems and minimizes inventory variants.

With its combination of high-current capability, efficient cooling, and advanced feedback loops, the DKR02.1-W300N-BE11-02-FW excels in applications ranging from machine tool spindles to packaging machinery. Engineers will appreciate the streamlined cabinet requirements afforded by the rigid DC bus topology and lack of external brake choppers, which simplifies installation and service. Bosch Rexroth Indramat’s proven drive architecture ensures consistent performance and long-term reliability in industrial automation environments.
