Product Description:
The DKR03.1-W200N-BE is a drive controller produced by Bosch Rexroth Indramat for the DKR Drive Controllers series. In an automation cell, this unit governs servo axes by converting motion commands into the regulated current and voltage that a connected motor requires. The controller forms the core of a closed-loop system, coordinating position, speed, and torque so machinery follows programmed trajectories without deviation.
Communication with the host control system takes place over the SERCOS interface, allowing deterministic exchange of setpoints and feedback data. Thermal management relies on a built in air blower; the integrated fan directs airflow across internal components to prevent overheating during continuous duty. The power stage is specified with No bleeder, meaning excess regenerative energy is not dissipated through a braking resistor but is instead handled on a rigid DC bus, so upstream supply hardware must accommodate that energy. For motor position monitoring the unit accepts Digital servo and resolver feedback, giving flexibility to operate both modern absolute encoders and traditional resolver-equipped motors without external converters.
Lifecycle and compatibility details are defined by Design Version 1 and the hardware’s Line Series 03 identifier; these numbers help users match the controller to firmware, option cards, and replacement parts released for the same build generation. The remaining parameters combine to give integrators a precise map of how the product fits into larger motion systems from Bosch Rexroth Indramat. Within the wider DKR Drive Controllers series, this model therefore serves installations that require real-time SERCOS networking, internal air cooling, and a DC bus strategy that omits a brake chopper while still guaranteeing reliable servo control.
