DKR02.1-W300B-BE43-02-FW
DKR Drive Controllers
The Bosch Rexroth Indramat DKR02.1-W300B-BE43-02-FW is a high-performance drive controller in the DKR Drive Controllers series, engineered to deliver precision and reliability in demanding automation environments. This unit features a Current Rating of 300 A and a Nominal Current of Approx 300A, ensuring consistent power delivery for medium- to high-power servo systems. Built to Design Version 1 standards, the controller incorporates a Bleeder Configuration with bleeder for safe DC-link discharge and a Line Series 02 layout for streamlined installation. Identified by its Function Numeric Code 43 and classified under the Product Series DKR, it supports advanced motion tasks with robust hardware integration.
Seamless communication is achieved through its integrated Command Interface: SERCOS interface, which enables real-time synchronization and low-latency data exchange. The controller’s Cooling Method: Air (built-in blower) provides efficient thermal management, maintaining optimal operating temperatures without external fans. Digital control is further enhanced by dual-mode Motor Feedback: Digital servo and resolver feedback, delivering precise position and velocity data to the drive. Its compact form factor and modular design facilitate rapid integration into existing control cabinets or bespoke machine architectures.
Engineered for industrial duty cycles, the DKR02.1-W300B-BE43-02-FW combines simplicity with ruggedness to minimize downtime and commissioning effort. Its built-in bleeder and advanced feedback interfaces reduce system complexity, while the robust air-blower cooling arrangement ensures consistent performance under continuous load. As a core member of the DKR controller family, this device is ideally suited for precision machining, robotics, and material handling applications where high current capacity and fail-safe operation are paramount.
