Product Description:

The DKR02.1-W300N-BE06-01-FW drive controller is produced by Bosch Rexroth Indramat within the DKR Drive Controllers series. As a digital intelligent AC drive controller, it governs high-power servo axes in industrial automation lines by translating network commands into regulated current and voltage for compatible motors. It integrates into multi-axis motion platforms where rapid torque control and coordinated positioning are essential. This type of unit is commonly used where several axes must respond with consistent timing during demanding machine cycles.

The drive exchanges real-time setpoints over the SERCOS interface, while digital servo and resolver feedback return position data for precise closed-loop regulation. At a switching frequency of 4 kHz, it provides a continuous armature current of 141 A, which supports about 55 kW of sustained shaft power. Control electronics accept an AC 230 V supply that can deviate by ±10%, and the power section is kept within temperature limits by a built-in air blower that circulates cabinet air. Because the design uses a rigid DC bus without a bleeder or brake chopper, regenerated energy must be handled by the shared bus or by external hardware. The numeric current rating of 300 identifies its capacity class, while line series 02, design version 1, and function module 01 indicate the product configuration used for this unit.

During acceleration peaks, the controller can output 212 A before reaching instantaneous limits, and it draws power from a 3×AC 400–480 V mains connection with a permissible ±10% deviation. Continuous operation produces 1800 W of heat that the blower expels to the surroundings. The frame weighs 104 kg, which affects cabinet support requirements and handling arrangements, and the heat output must be considered in enclosure loading.
