Product Description:

The DKR02.1-W200Z-BE23-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the DKR Drive Controllers series. The unit acts as the control stage for servo power modules, coordinating axis behavior so connected motors can respond accurately to commands from a higher-level PLC or CNC. In automated machinery, this supports synchronized motion, repeatable positioning, and controlled speed changes during tasks such as feeding, indexing, cutting, and transfer operations. Its role in the drive system is to manage the motion relationship between commanded values and the electrical output delivered through the associated power hardware.

The controller exchanges real-time setpoints and status data over the SERCOS interface, so fiber-optic rings can network multiple axes without analog wiring. This communication method supports deterministic data transfer and helps reduce sensitivity to electrical noise inside industrial cabinets. Internally, heat is removed by a built-in air blower, and the integrated fan directs airflow across the power semiconductors to keep temperatures within normal operating limits. The unit is identified as Design version 1, which marks this physical layout and connector arrangement. It is also part of Line 02, placing it in the second design line of the DKR platform.

The controller uses Function version 01 for its application grouping within the product line. Feedback channels support both digital servo feedback and resolver feedback, allowing the same unit to work with motors that use either encoder-based signals or resolver-based signals. This broad feedback support allows the controller to serve high-response servo axes and other closed-loop motion applications without requiring a different controller design. Digital servo feedback supplies detailed position information, while resolver feedback provides durable analog angle signals that remain useful in demanding industrial environments.
