Product Description:

The DKR02.1-W200Z-BE79-01-FW is a drive controller in the DKR Drive Controllers series developed by Bosch Rexroth Indramat. It supplies regulated DC bus power and closed-loop motion commands to servo and spindle motors, acting as the central axis module in machining centers, printing presses, and automated handling cells. By integrating power conversion, control electronics, and diagnostic facilities in one enclosure, the unit reduces cabinet space and shortens installation time.

Communication with supervisory controls is achieved through the SERCOS interface, a deterministic serial bus that exchanges position data and parameters on a fiber or plastic-optical ring. The deterministic link supports cycle times down to one millisecond for tight speed loops. Thermal management is provided by air cooling aided by a built-in blower, so heat is ejected directly from the housing without external fans. The controller accepts digital servo feedback from high-resolution encoders and separate resolver feedback for motors that use hybrid analog transducers, enabling mixed drive trains to share the same hardware. These interfaces allow quick commissioning, automatic electronic name-plate reading, and continuous condition monitoring at the drive level.

Model identifiers printed on the front panel clarify hardware compatibility. The designation belongs to line series 02, indicating component layout and connector style, and it carries design version 1, which defines mechanical tolerances for mounting rails. Embedded firmware is tagged as function numeric version 01, ensuring parameter files created for matching versions load without conversion. Inside the wider DKR family, these coded segments let technicians match option cards, cable kits, and spare drives to the correct generation during system maintenance.
