DKR03.1-W200N-BE37-01-FW

DKR03.1-W200N-BE37-01-FW, manufactured by Bosch Rexroth Indramat, is a member of the robust DKR Drive Controllers series designed for high-performance industrial motion control. This digital electrical controller delivers precise real-time management of servo and resolver feedback loops to optimize motor functions such as speed, torque, and direction. The controller accepts a grounded 3-phase AC input of 400–480 V and only engages once safety interlocks confirm all monitored parameters are within safe limits. A built-in blower ensures consistent cooling under heavy duty cycles and the compact footprint facilitates integration into CNC, printing, or automated assembly machines.

In terms of specifications, the unit provides a continuous Rated Current (A) of 200 A to drive demanding motor loads, while the Bleeder Configuration is implemented “No bleeder / Without brake chopper, rigid DC bus” to maintain a stable DC link. Communication is handled via the high-speed Command Interface of SERCOS interface, enabling deterministic data exchange and synchronized multi-axis coordination. The Cooling Method is Air (built-in blower), eliminating the need for external fans and reducing maintenance. Internally, the controller is identified by Design Version 1, Line Series 03, and Function Numeric Version 01, reflecting its firmware and hardware revision levels. It supports Motor Feedback through both digital servo and resolver feedback channels, ensuring adaptable compatibility with a wide range of Rexroth Indramat and third-party motors.

Engineers benefit from rapid parameter cloning and automated safety checks that prevent system startups under fault conditions, improving uptime and safeguarding personnel. The DKR03.1-W200N-BE37-01-FW integrates seamlessly into existing Bosch Rexroth automation environments via standardized SERCOS protocols, while its rugged design and built-in blower guarantee reliable operation in harsh industrial settings. Ideal for machine builders seeking precise, dependable drive controllers in high-speed CNC, printing, or packaging applications.
