Product Description:

The DKR03.1-W200Z-BE12-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the DKR Drive Controllers series. In automated machinery, this unit regulates servo axes by converting incoming commands into timed current and voltage patterns for the connected motor. Its role is to coordinate motion profiles, monitor feedback, and maintain stable speed or position loops so that plant equipment runs within normal operating tolerances. By shaping motor output in real time, it helps axes accelerate, decelerate, and hold commanded positions with consistent behavior during changing loads.

Communication with higher-level PLCs is handled through the SERCOS interface, a serial real-time bus that carries position, velocity, and diagnostic data in deterministic cycles. Deterministic timing is important in machines where several axes must exchange status and command data without irregular update intervals. Thermal management is provided by a built-in air blower, so internal airflow moves cabinet air across heat-producing components and helps keep semiconductor temperatures within range. The controller interprets digital servo and resolver feedback, allowing it to process high-resolution encoder data or resolver sine-cosine signals without external converters.

The unit is Design Version 1, which identifies this revision of the component layout and connector arrangement. It also carries Function Numeric Version 01, indicating the basic motion-control function set used for this release. The controller is built in Line Series 03, and its mechanical dimensions, terminal locations, and internal bus routing follow that line. Within the same line, enclosure geometry and terminal placement stay consistent with the documented layout for this revision, and the combination of these identifiers distinguishes the controller from later releases.
