DKR04.1-W300N-BT29-02-FW

The Bosch Rexroth Indramat DKR04.1-W300N-BT29-02-FW drive controller from the DKR Drive Controllers series integrates seamlessly into modern automation architectures and delivers high-precision performance with a nominal current of Approx 300A and a current rating of 300. This controller, designated as Design Version 1, leverages a robust Line Series 04 power stage to support dynamic loads and maintain regulator stability under varying torque demands. Communication is handled via the high-speed SERCOS interface, enabling deterministic data exchange and synchronized multi-axis motion. A built-in blower provides active air cooling, ensuring consistent heat dissipation even in demanding industrial environments.

Reliability is further enhanced by the controller’s Bleeder Configuration: No bleeder/Without brake chopper, rigid DC bus, which preserves bus voltage stability and simplifies DC‐link protection schemes. The system’s native support for both digital servo feedback and resolver feedback ensures accurate position and velocity monitoring across a wide range of motor types. Its compact mechanical design follows the DKR product series footprint, offering straightforward retrofit into existing control cabinets. Maintenance personnel benefit from modular access to power and control terminals, reducing downtime during service intervals.

In applications ranging from packaging machines to CNC machining centers, the DKR04.1-W300N-BT29-02-FW drive controller delivers precise torque control, high throughput, and enhanced system up-time. Tight integration with Bosch Rexroth Indramat automation components and standardized communication protocols accelerates commissioning and simplifies diagnostic workflows. This robust controller is engineered for continuous operation, providing long-term reliability in high-speed, high-precision industrial processes.
