Product Description:

The DKR03.1-W200N-BE24-01-FW is a digital intelligent AC drive controller produced by Bosch Rexroth Indramat within the DKR Drive Controllers series. As a closed-loop power unit, it conditions three-phase mains energy and delivers regulated current to servo motors in multi-axis machining centers, presses, and similar automated equipment. By integrating axis control, protection, and diagnostics in a single enclosure, the controller simplifies cabinet layout and supports synchronized motion in systems that require accurate torque and speed regulation across multiple coordinated axes.

The drive connects to plant mains through a rated power terminal that accepts 3 x AC 400–480 V with a tolerance of ±10%, and it uses a separate control circuit stabilized at AC 230 V (±10%) for its logic electronics. Within this electrical window, it can deliver a continuous armature current of 92 A at a switching frequency of 4 kHz, which corresponds to a sustained shaft power of 35 kW for the connected motor group. The internal 200 A rating code corresponds to the required conductor sizing. The unit is part of line series 03 with design version 1 and function module version 01. Under nominal load, the controller releases approximately 1200 W of thermal energy that must be removed by cabinet airflow.

Transient load steps are managed by a peak current capacity of 141 A, giving the module headroom for acceleration or shock loads before it returns to its continuous operating range. Cooling is handled by an integrated air cooling blower that moves exhaust across the heat sink, and the unit is supplied with no bleeder or brake chopper hardware. Real-time setpoints and status are exchanged over the fiber-optic SERCOS interface, while motor position data can be interpreted from either digital servo or resolver feedback channels. The housing weighs 49 kg, so mounting must account for static support and vibration isolation during operation.
