DKR04.1-W400N-BA35-01-FW

The Bosch Rexroth Indramat DKR04.1-W400N-BA35-01-FW drive controller from the DKR Drive Controllers series is designed for precise motion control in advanced automation systems. As part of the DKR product family, it features a Rated Current (A) of 400 A and operates with an efficient Air (built-in blower) Cooling Method to maintain optimal thermal performance. The controller provides a versatile Command Interface through an Analog interface, enabling straightforward integration with legacy systems. Its primary application is in controlling servo motors in industrial automation, ensuring high accuracy and reliability.

This model boasts a robust Bleeder Configuration with “No bleeder / Without brake chopper, rigid DC bus,” reducing electrical losses and simplifying bus design. The Motor Feedback supports both Digital servo and resolver feedback, delivering precise position and speed information for tight motion control loops. As a Design Version 1 unit in the Line Series 04, the controller reflects a mature architecture that balances performance and ease of maintenance. Its analog command interface is complemented by rugged internal electronics and a built-in blower for active cooling, ensuring consistent operation even under high-duty cycles.

Additional identifiers such as Function Numeric Version 01 and Product Series DKR highlight its place in the broader Rexroth Indramat ecosystem, guaranteeing compatibility with existing DKR modules. The rigid DC bus topology contributes to system durability by eliminating the need for external brake choppers, while the integrated blower design enhances energy efficiency and lowers maintenance overhead. Ideal for heavy-duty industrial applications involving high inertia loads or frequent start-stop cycles, the DKR04.1-W400N-BA35-01-FW drive controller delivers dependable performance, simplified integration, and long-term operational stability.
