Product Description:

The DKR02.1-W200N-BE12-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the DKR Drive Controllers series. It is intended to energize and regulate high-power servo and spindle motors used in machining centers, presses, and automated transfer lines, converting coordinated commands from a motion control system into precise current and voltage patterns on the motor phases.

This unit exchanges real-time setpoints and status data over the SERCOS interface, allowing deterministic communication with PLCs and multi-axis master controllers. Thermal management is handled by an internal Air (built-in blower) that directs cooling flow across the heatsink without external ducting. Position and velocity loops can be closed with either Digital servo and resolver feedback, giving flexibility when different motor encoder types share the same cabinet. The power section is tied to a rigid DC bus; because no bleeder or brake chopper is installed, excess regenerative energy must be absorbed by shared system components or external resistors. Hardware identification is stamped as Design Version 1, indicating the mechanical layout, connector style, and rating group defined for the second hardware generation of this controller family.

Firmware coordination is marked by Function Numeric Version 01, so application software, parameter files, and diagnostic tools must target this release to avoid incompatibilities. The controller belongs to Line Series 02, a class that groups devices with identical gate-drive electronics and protective logic, simplifying spare-part strategies. Within the wider product catalog, the highlighted DKR architecture provides a common pinout and programming model across multiple power classes, enabling rapid replacement. Ongoing field support is streamlined because Bosch Rexroth Indramat maintains uniform test procedures and service firmware for every hardware and function combination referenced above.
