DKR02.1-W300N-BE11
DKR Drive Controllers
The Bosch Rexroth Indramat DKR02.1-W300N-BE11 from the DKR Drive Controllers series by Bosch Rexroth Indramat combines precision control with industrial resiliency. As part of the Product Series DKR and the Line Series 02, this controller is engineered for high-performance motion applications requiring a Current Rating of 300 A and a Nominal Current of approximately 300 A. It features a factory-assigned Function Numeric Code 11 and a matching Version Function Numeric Code Factory Assigned for streamlined configuration management. The controller is built on Design Version 1, ensuring compliance with the latest firmware standards.
The drive controller’s interface and cooling subsystems are optimized for demanding environments. It integrates a high-speed SERCOS interface command interface for deterministic communication and digital synchronization. A built-in blower implements Air cooling without requiring external chillers, while the DC bus operates in a No bleeder/Without brake chopper, rigid DC bus configuration for maximum energy retention during dynamic braking. Motor position feedback is handled via digital servo and resolver feedback, delivering sub-micrometer accuracy and robust noise immunity.
Engineers benefit from straightforward adaptation within multi-axis architectures and easy cabinet integration thanks to the compact form factor and industry-standard mounting. The ruggedized design minimizes downtime and extends operational life, even under continuous 24/7 load cycles. With its combination of line series pedigree, high-current handling, and advanced servo feedback, the DKR02.1-W300N-BE11 is ideal for precision CNC machinery, robotics, and automated production lines where reliability and real-time performance are mission-critical.
