Product Description:

The DKR02.1-W200B-BE23-01-FW is a drive controller produced by Bosch Rexroth Indramat as part of the DKR Drive Controllers series. Serving as an axis controller for high-power servo motors, it converts line power into regulated three-phase output while managing torque, speed, and position loops in machine tools, printing lines, and other automated equipment. Its integrated power stage and control electronics allow rapid deceleration and precise synchronization between multiple axes. This arrangement lets one controller handle power conversion and closed-loop regulation in the same enclosure. It also provides overcurrent, overvoltage, and thermal protection during continuous-duty operation, which helps the drive remain stable when load demand changes quickly.

For energy dissipation during fast braking, the unit is supplied with a bleeder, an internal resistor set that channels excess DC-bus energy into heat instead of returning it to the mains. Communication with the motion controller occurs through the SERCOS interface, so parameter data and cyclic setpoints travel over a fiber-optic ring without additional wiring complexity. Thermal management relies on a built-in air blower, which moves ambient air through the heat sink and removes the need for cabinet water lines. Motion feedback compatibility spans digital servo and resolver feedback, allowing the drive to process either encoder or resolver signals for commutation and diagnostics. This combination supports controlled braking, stable heat removal, and flexible motor feedback connection in demanding automation tasks.

This hardware belongs to Line Series 02. It is manufactured as Design Version 1, so the controller follows the first mechanical release of this platform. The unit carries Function Numeric Version 01, which marks the initial function set for this release. These identifiers distinguish the controller build within the product line and separate it from later revisions. They also indicate which control features are available on the unit without changing its basic operating purpose.
