DKR04.1-W400N-BA08-01-FW

The Bosch Rexroth Indramat DKR04.1-W400N-BA08-01-FW from the DKR Drive Controllers series combines precision engineering with heavy-duty performance. This controller features a Product Series DKR architecture and a Line Series 04 design, with a Design Version 1 hardware platform. Capable of delivering a Rated Current (A) of 400 A, it supports high-power servo applications while maintaining exceptional stability. Communications are handled via an Analog interface for straightforward integration into standard control systems.

Built-in cooling is managed by an Air (built-in blower) system that ensures consistent thermal regulation under continuous load. The absence of a bleeder and brake chopper is addressed by a Bleeder Configuration: No bleeder/Without brake chopper, rigid DC bus, simplifying the DC bus design and reducing maintenance points. Feedback loops are closed with Digital servo and resolver feedback, enabling high-resolution position and velocity monitoring. The Function Numeric Version 01 firmware offers deterministic control cycles and advanced tuning parameters for optimized dynamic response.

Engineers will appreciate the compact footprint and service-friendly layout that Bosch Rexroth is known for. The stiff DC bus topology allows rapid torque application without derating, making the DKR04.1-W400N-BA08-01-FW ideal for indexed motion, gantry systems, and multi-axis coordination. Integrated fault diagnostics and status flags accelerate troubleshooting, while robust mechanical and electronic design ensure long-term reliability. This controller stands out as a flexible, high-current solution for demanding industrial automation environments.
