DKR03.1-W100N-BE45-01-FW
DKR Drive Controllers
DKR03.1-W100N-BE45-01-FW, manufactured by Bosch Rexroth Indramat, belongs to the high-performance DKR Drive Controllers series designed for precision motion control in demanding industrial applications. This drive controller delivers a continuous Rated Current (A) of 100 A and supports advanced automation networks via its native Command Interface. Built to the rugged specifications of the DKR product family, it ensures repeatable, high-speed performance for both servo and resolver motor topologies. The compact enclosure houses all essential power and control electronics, optimizing cabinet space without sacrificing functionality.
Incorporating a Bleeder Configuration with no bleeder and a rigid DC bus, the DKR03.1-W100N-BE45-01-FW maintains DC stability under transient loads and simplifies installation by omitting an external brake chopper. Communication is handled through a real-time SERCOS interface, guaranteeing deterministic cycle times and seamless multi-axis synchronization. Motor position and velocity are derived from Digital servo and resolver feedback, enabling sub-micron accuracy and dynamic response. Thermal management is provided by an integrated Air (built-in blower) cooling system that maintains optimal junction temperatures without external fans. The drive’s internal labeling corresponds to Design Version 1 and Function Numeric Version 01, while its Line Series designation of 03 aligns with Rexroth’s modular performance classes.
Engineers benefit from the DKR03.1-W100N-BE45-01-FW’s plug-and-play integration into existing SERCOS topologies, reducing commissioning time and minimizing wiring complexity. Its robust design and built-in blower contribute to high reliability and continuous operation in harsh environments. Ideal for packaging machines, CNC tooling centers, and automated assembly lines, this Bosch Rexroth Indramat drive controller delivers consistent, high-precision motion control with minimal maintenance.
