Product Description:

The DKR02.1-W300Z-BE11-02-FW is a drive controller built by Bosch Rexroth Indramat for the DKR Drive Controllers series. It regulates large servo motors in high-power machine tools, printing presses, and handling systems, converting command data into phase-controlled current for the connected motor. By combining power electronics, signal processing, and protective monitoring in one housing, the unit supports synchronized multi-axis operation and reduces the amount of separate hardware required in the cabinet. That arrangement helps the controller maintain coordinated motion when several axes must respond together under changing load conditions.

This controller exchanges cyclic setpoints and status data through the SERCOS interface, which provides real-time communication with the higher-level motion system. Thermal energy is removed by a built-in air blower, so cooling is handled inside the unit rather than by an external heat exchanger. The power stage has a continuous current rating of 300 A, giving the axis the capacity needed for rapid acceleration of heavy inertial loads. The unit is identified as Design version 1. This combination of internal cooling and high current capability suits axes that see sustained torque demand during long production cycles.

The controller is part of Line 02 in the product range. Velocity and position control use digital servo and resolver feedback, so the drive can work with either feedback method depending on the connected motor. The internal diagnostics refer to this connection as motor feedback, making the menu terminology consistent with the supported feedback options. This arrangement allows one controller platform to support different motor configurations in complex machine layouts without changing the basic control concept. Because the feedback channel is integrated into the controller, operating status and response information remain available during closed-loop motion.
