DKR03.1-W100N-BA04-01-FW

The Bosch Rexroth Indramat DKR03.1-W100N-BA04-01-FW drive controller is part of the renowned DKR Drive Controllers series, engineered for precise servo motion control in demanding industrial automation systems. This unit delivers a rated current of 100 A and incorporates an efficient air (built-in blower) cooling method to ensure reliable operation under continuous load. Designed to integrate seamlessly with modern manufacturing equipment, the DKR03.1-W100N-BA04-01-FW provides robust performance for a wide range of servo motor applications requiring both rapid response and sustained torque control.

In terms of technical details, the controller features a bleeder configuration of "No bleeder / Without brake chopper, rigid DC bus," optimizing DC bus rigidity for stable voltage supply and minimizing energy losses. The command interface is an analog interface, allowing smooth, variable reference signals for speed or torque control. Feedback is handled via digital servo and resolver feedback, ensuring high-precision position and velocity measurement. Further identifiers include design version 1, line series 03, and function numeric version 01, each reflecting the controller’s iterative improvements and compatibility with legacy DKR components.

Additional advantages of the DKR03.1-W100N-BA04-01-FW include its adherence to the DKR product series standards, ensuring seamless integration with existing Bosch Rexroth Indramat systems and accessories. The built-in blower cooling not only enhances thermal management but also reduces maintenance requirements compared to liquid-cooled units. Its rigid DC bus design delivers improved durability and electrical noise immunity, critical for high-precision manufacturing environments. By combining reliable analog control with advanced digital feedback mechanisms, this DKR controller offers efficient energy usage, precise motion control, and long-term operational stability—ideal for assembly lines, robotics, and process automation in industrial settings.
