Product Description:

Bosch Rexroth Indramat's DKR 2.1-W300Z-BE01-00 is a modular AC drive controller in the DKR Drive Controllers series. It is intended for multi-axis machining centers and high-speed automation cells, where it supplies regulated three-phase power and controls velocity and torque for synchronous or asynchronous servo motors. By exchanging real-time data with the plant host, the unit coordinates spindle rotation and feed motion so that tooling, handling, and forming operations follow programmed paths with repeatable accuracy. This makes it suitable for machine sections where accurate spindle speed and coordinated feed travel must be maintained throughout a production cycle.

Communication with upstream PLCs is handled through a SERCOS interface, using a fiber-optic ring for fast transfer of setpoints and diagnostic data. The continuous output section is rated for 300 A, which supports large spindle or gantry axes that draw sustained current under heavy load. Thermal energy is removed by air cooling with a built-in blower, so the cabinet does not require external liquid cooling lines. The controller can process digital servo and resolver feedback, which allows compatibility with different motor feedback types. For acceleration demands, the power stage can deliver up to 212 A for short overload intervals without immediately entering a fault state.

The controller is design version 1. It uses function module 01, and the control version is 00. The unit is classified as a Digital Intelligent AC Drive Controller. These identifiers keep the parameter structure consistent across matching units and help keep system data organized in larger multi-axis installations. The versioning also separates functional behavior from the power section, which supports predictable operation when several similar controllers are used on the same control network.
