Product Description:

The DKR03.1-W200Z-BE79-01-FW is a drive controller produced by Bosch Rexroth Indramat within the DKR Drive Controllers series. It serves as the power and control stage between an industrial motion controller and a servo motor, handling real-time torque, speed, and position regulation on production machinery, robotics, and material-handling axes. This arrangement allows the controller to translate command data into regulated motor response while maintaining stable axis performance during changing loads and duty cycles. Because it combines power conversion and closed-loop regulation in one unit, it can support coordinated motion where accurate response is required at both low and changing speeds.

For fieldbus communication, the unit relies on the SERCOS interface, enabling deterministic cyclic data exchange with multi-axis CNC or PLC systems. Thermal management is handled by a built-in air blower, so cabinet integration does not require external ducting or water cooling. Motor position signals are accepted through digital servo and resolver feedback, allowing the same controller to work with high-resolution optical encoders as well as rugged resolver transducers. The unit is listed as Design Version 1 and belongs to Line 03, which places it within the third design line of this controller platform.

The controller uses Function Numeric Version 01, which identifies the assigned motion-control feature set for this configuration. It also includes integrated overcurrent and overtemperature monitoring to protect internal components during continuous operation on automated lines. These protective functions help the controller respond to abnormal electrical or thermal conditions before damage develops in the power section. The overall layout remains suitable for installations that require regulated servo control, consistent feedback processing, and direct integration into established SERCOS-based systems.
