DKR04.1-W400E-BE74-02-FW

DKR04.1-W400E-BE74-02-FW, a robust controller from Bosch Rexroth Indramat in the DKR Drive Controllers series, delivers up to 400 A of regulated motor power with precision and stability. Its compact footprint houses a high-performance DC bus and brake chopper, enabling seamless integration into modern automation lines. With an on-board External bleeder/ With brake chopper, rigid DC bus arrangement, it mitigates voltage spikes and ensures smooth torque control under dynamic loads. The controller’s firmware suite supports advanced motion profiles and real-time diagnostic feedback, optimizing throughput and minimizing cycle times.

Designed for demanding industrial environments, the unit is built on Design Version 1 hardware and features a dedicated Air (built-in blower) cooling system to sustain continuous operation across temperature variations. Command and data exchange occur via the deterministic SERCOS interface, offering microsecond-level synchronization with peripheral drives and PLCs. The device belongs to the proven Product Series DKR and Line Series 04, ensuring compatibility with existing Rexroth drive ecosystems. High-resolution position feedback is provided through dual-mode Digital servo and resolver feedback channels, enabling sub-micron accuracy and fast loop response.

Engineers value the DKR04.1-W400E-BE74-02-FW for its streamlined integration into multi-axis architectures and its enterprise-grade reliability. Built-in safety margins and modular bleeder configuration reduce downtime by simplifying maintenance and field upgrades. Ideal for packaging, printing, and CNC applications, this controller elevates system efficiency and extends service intervals, delivering tangible cost savings in high-volume production.
