Product Description:
The DKR03.1-W200B-BA01-01-FW is a digital intelligent AC drive controller manufactured by Bosch Rexroth Indramat as part of the DKR Drive Controllers series. It converts incoming three-phase power into regulated output for synchronous or induction servomotors used in machine tools, presses, and automated transfer systems. By modulating voltage and frequency, the unit aligns motor torque and speed with the programmed motion profile required by industrial CNC and material-handling equipment. This arrangement supports controlled acceleration, steady running speed, and responsive changes in load-driven applications.
The power stage accepts 3×AC 400–480 V mains, while a separate logic supply runs from AC 230 V ±10 %. At a 4 kHz switching frequency, the inverter provides a continuous armature current of 92 A, and it can momentarily reach 141 A to meet acceleration demands. Under these conditions, the drive supports motor output up to 35 kW for heavy-axis operation. Command signals are handled through an analog interface, and digital servo plus resolver feedback return precise position data to the controller. The combination of analog command input and closed-loop feedback allows the drive to regulate motor behavior with accurate speed and position response.
A built-in blower forces air through the housing to remove heat, and an internal bleeder dissipates surplus DC-bus energy through a brake resistor rated for 1 kW of continuous dissipation and up to 150 kWs per stop. The electronics release 1200 W of heat at maximum load, and the airflow helps keep component temperatures within the permitted range during sustained operation. The unit is part of line series 03, design version 1, and function module 01 with version 01. It has a mass of 49 kg, which should be considered when selecting panel mounting hardware and structural support.
