Product Description:
The DKR03.1-W200N-BA24-01-FW is produced by Bosch Rexroth Indramat for the DKR Drive Controllers series. As a digital intelligent AC drive controller, it coordinates high-power servo or spindle axes in automated machining centers, presses, and handling cells. It converts line energy into precisely regulated three-phase output for closed-loop motion tasks and supports accurate control of speed, torque, and axis response.
The unit operates on a rated power grid of 3 x AC 400–480 V and supplies a continuous armature current of 92 A at a 4 kHz switching frequency, allowing steady torque production from large motors. A continuous drive power capability of 35 kW supports multi-kilowatt loads typical of main spindles and other demanding axes. Internal logic and fan circuits use their own AC 230 V control voltage, which keeps the command electronics separate from the main power section. Motion commands enter through an analog interface, while the controller accepts both digital servo and resolver feedback for position verification. This combination allows the drive to work with different motor feedback arrangements used in industrial motion systems. Thermal management relies on a built-in air blower, so installation only requires clearance for forced airflow rather than external ducting. The design omits a brake chopper, so regenerated energy must be handled on the line side or by mechanical damping. Current rating class 200, line series 03, design version 1, and function module version 01 identify the unit within the modular drive platform.
During acceleration or shock loading, the drive can deliver a peak current of 141 A, providing short-term torque without exceeding semiconductor limits. At full load, the controller releases 1200 W of heat, which is important when sizing cabinet ventilation and spacing nearby components. The enclosure weighs 49 kg, so panel mounting must support that static mass as well as vibration during machine operation. This mass also affects enclosure layout because the unit needs secure fastening and adequate structural support.
