DKR04.1-W400N-BA05-01-FW

DKR04.1-W400N-BA05-01-FW, Bosch Rexroth Indramat, DKR Drive Controllers sets a new benchmark in high-performance motion control. This drive controller features a 400 A continuous output capacity, supporting industrial applications that demand robust power delivery. Engineered within the Line Series 04 design platform, it assumes a compact footprint while preserving advanced functionality. The inclusion of Product Series DKR identity and Function Numeric Version 01 ensures seamless compatibility with legacy Rexroth systems and simplifies fleet standardization.

Built for precision, the DKR04.1-W400N-BA05-01-FW integrates a Digital servo and resolver feedback loop to deliver accurate position and velocity regulation. It communicates via an Analog interface command interface, enabling direct integration with conventional PLCs and motion controllers. The controller employs a rigid DC bus topology with No bleeder / Without brake chopper configuration, eliminating external resistor assemblies and reducing cabinet complexity. Thermally managed by an Air (built-in blower) cooling method, it maintains optimal junction temperatures under sustained 400 A loads. Internally tracked as Design Version 1, it incorporates refined power electronics to support dynamic load changes without derating.

System installers and machine builders benefit from the DKR04.1-W400N-BA05-01-FW’s plug-and-play wiring scheme, which leverages standard Rexroth mounting dimensions and connectors. Its robust architecture delivers high reliability even in demanding production environments, minimizing unplanned downtime. Whether deployed in packaging lines, metalworking spindles, or automated assembly cells, this drive controller streamlines integration and accelerates time-to-operation while upholding Rexroth’s reputation for industrial endurance.
