DKR Drive Controllers
The DKR03.1-W200Z-BE15-01-FW, manufactured by Bosch Rexroth Indramat, belongs to the DKR Drive Controllers series and serves as an advanced digital drive controller for industrial servo systems. With a rated current of 200 A and a SERCOS interface for command communication, this controller delivers precise motion control and monitoring for Indramat servo motors. It is specifically engineered to interface with LSF linear motors, frameless spindle motors, and 2AD AC main spindle motor series, providing seamless integration and exceptional performance.
Designed for reliability, the DKR03.1 drive controller features a built-in blower air cooling mechanism and supports both digital servo and resolver feedback for accurate position and speed regulation. The product series is specified under the DKR product line, design version 1, line series 03, and function numeric version 01. The bleeder function remains Undefined, offering flexibility in regenerative energy management. Its robust architecture accommodates specialized configuration cards in slots U1 to U5 and requires an FWA-DIAX03 firmware module (ordered separately) for tailored application settings.
Built to IP20 protection standards, the controller is optimized for indoor industrial environments free from dust and liquids. It operates on a control voltage of AC 230 volts with a control power rating of 200 VA and weighs approximately 4.9 kg (accessories 1.7 kg), ensuring manageable installation and serviceability. In the event of power interruption, it leverages regenerated kinetic energy from the servo motor to maintain operation, enhancing process continuity. The DKR03.1 drive controller offers high efficiency, configurability, and durability, making it an ideal choice for demanding industrial automation applications.

Frequently Asked Questions
How does the DKR03.1-W200Z-BE15-01-FW handle command communication in multi-axis systems?
It uses the SERCOS interface, which standardizes digital communication and reduces wiring complexity. This allows synchronized motion control across multiple axes with minimal latency.
What is the practical impact of supporting both digital servo and resolver feedback?
This enables the controller to adapt to different motor encoder technologies. It ensures precise regulation of speed and position, even in varied machine configurations.
Why does the unit require a separate firmware module (FWA-DIAX03)?
The firmware defines specific application settings and motion profiles. Keeping it separate allows users to upgrade or reconfigure functions without replacing the hardware.
How do specialized configuration cards affect system flexibility?
Cards in slots U1–U5 expand interface or control functions. This modular design allows tailoring the controller to unique machine requirements without redesigning the base system.
What considerations apply when integrating LSF linear motors with this controller?
The drive provides precise current regulation tailored for linear motion. This minimizes cogging effects and ensures smooth travel in demanding positioning tasks.
