Product Description:

The DKR03.1-W200N-BE24-00 is a digital intelligent AC drive controller produced by Bosch Rexroth Indramat within the DKR Drive Controllers series. It belongs to a high-power controller product group and governs three-phase servo motors used in machining centers, gantry axes, and automated material-handling equipment. By modulating the power stage in response to real-time feedback, the unit supports precise torque and speed regulation for coordinated multi-axis motion in industrial automation cells.

The drive exchanges real-time position and velocity commands through the SERCOS interface, so it connects to digital CNC or PLC platforms without additional I/O converters. At a 4 kHz switching frequency, it supplies a continuous current of 92 A, which corresponds to 35 kW of sustained mechanical output during continuous duty. The control electronics draw from AC 230 V ±10%, independent of the power bus, and heat is removed by a built-in air blower. The unit has a current rating of 200 amperes, and the separate control supply allows the control section to remain powered independently of the main power bus. With its rigid DC bus, the controller does not include a bleeder or an internal brake chopper.

For short acceleration bursts, the inverter delivers a peak current of 141 A, enabling rapid speed changes without saturation. The power stage accepts mains from 3 x AC 400 to 480 V ±10%, covering common industrial supplies in North America and Europe. At full load, the assembly dissipates 1200 W, so cabinet ventilation must account for this thermal output and keep heat away from nearby components. Digital servo and resolver feedback channels provide fine position reporting for closed-loop operation. The controller is design version 1, part of line 03, and uses function module version 00. The drive weighs 49 kg and relies on external braking resistors when regenerative energy exceeds absorption capacity.
