Product Description:

The DKR03.1-W200Z-BE28-00 is a digital intelligent AC drive controller produced by Bosch Rexroth Indramat within the DKR Drive Controllers series. It belongs to line series 03 with design version 1, and it uses function module version 00. The unit controls torque, speed, and position of large servo motors in automated machinery. Internal current regulation and connected feedback channels help it maintain commanded motion profiles during changing loads, coordinated moves, and repeated production cycles. Because it is a closed-loop controller rather than a simple power stage, it works with motor feedback to correct speed deviation and position error as operating conditions change.

At a switching frequency of 4 kHz, the drive can deliver a continuous output current of 92 A and a sustained mechanical power of 35 kW when it is paired with suitable motors. The power section operates from a 3x AC 400–480 V ±10% line supply, while the control circuits require AC 230 V ±10%. During acceleration and other transient events, current can rise to a peak of 141 A, giving the axis short-term overload capacity. Digital servo and resolver feedback channels connect directly to the controller, allowing position data to be processed quickly so current regulation stays aligned with motor response.

Data exchange with higher-level PLCs is handled through the SERCOS interface, which supports deterministic communication for real-time coordination of multiple axes. Thermal management uses air cooling with a built-in blower, and the unit releases about 1200 W of heat under rated conditions, so cabinet airflow must remove that heat effectively. The housing weighs 49 kg, so the mounting structure must support a substantial drive assembly without excessive deflection. Typical applications include packaging lines, gantry systems, and processing equipment where controlled motor response is important.
