DKR04.1-W400N-BE56-01-FW
DKR Drive Controllers
The Bosch Rexroth Indramat DKR04.1-W400N-BE56-01-FW controller from the DKR Drive Controllers series is engineered for demanding industrial motion applications. It features a rated current of 400 A and adheres to Design Version 1 standards, ensuring compatibility and longevity. As part of Product Series DKR with Line Series 04 and Function Numeric Version 01, this unit offers a coherent platform for uniform performance across automated systems. The integrated architecture supports precise digital control while maintaining a compact footprint suitable for dense control cabinets.
Engineered for seamless communication and robust operation, the DKR04.1-W400N-BE56-01-FW utilizes a SERCOS interface command bus to deliver deterministic synchronization with minimal latency. Adaptive thermal management is provided by the Air (built-in blower) cooling method, which maintains optimal operating temperatures even under continuous full-load conditions. Motor monitoring and loop closure rely on digital servo and resolver feedback, granting high-fidelity response for spindle, frameless, and linear motor configurations. The absence of a brake chopper, confirmed by the Bleeder Configuration: No bleeder/Without brake chopper, rigid DC bus, simplifies installation while delivering stable DC-link voltage for regenerative loads.
Installation and maintenance are streamlined through standardized module slots and transparent versioning, avoiding cross-compatibility issues. Built-in fans and a rigid DC bus reduce points of failure, bolstering system uptime in process and machine-tool environments. As a result, the Bosch Rexroth Indramat DKR04.1-W400N-BE56-01-FW stands as a reliable, high-current drive controller that adapts to diverse applications without sacrificing performance or safety.
