Internal Product Review
The DKR02.1-W300Z-BE01-00 is a digital intelligent AC drive controller with a SERCOS interface. Continuous drive power of about 55 kW at 4 kHz and peak current of 212 A give this unit impressive headroom for demanding motion applications. Built-in blower cooling supports stable thermal performance, making the controller a very capable choice for 400 to 480 V drive systems.

Product Description:
The DKR02.1-W300Z-BE01-00 is a digital intelligent AC drive controller produced by Bosch Rexroth Indramat for the DKR Drive Controllers series. It is intended to regulate large servomotors and spindle units in machining centers, presses, and general automation lines where closed-loop velocity and torque control are required. The unit coordinates motion commands from higher-level PLCs and converts them into three-phase drive power for precision electromechanical axes. This makes it suitable for applications that require repeatable acceleration, controlled deceleration, and steady torque delivery under changing load conditions.
Communication with the motion control system occurs over the SERCOS interface, allowing deterministic fiber-optic transfer of setpoints and status bits. To supply power to the motor windings, the drive can deliver a continuous current of 141 A at a 4 kHz switching frequency, and this rating indicates the sustained thermal load the power stage can carry without derating. During rapid acceleration events, the output can reach a peak of 212 A, providing short-term torque reserve before returning to its continuous limit. Power is drawn from a mains supply of 3×AC 400–480 V ± 10 %, while auxiliary logic circuits are maintained by a separate AC 230 V ± 10 % control line that helps isolate command electronics from load disturbances.
The power module is specified for a continuous mechanical output of 55 kW, which matches large axis demands when combined with correctly sized motors. Thermal stability is supported by a built-in air blower that forces cabinet air across the heat sink; under full load, the assembly releases 1800 W of loss energy that must be removed from the enclosure. A mass of 104 kg helps secure the controller in the panel and adds thermal inertia. Digital servo and resolver feedback channels support fine position loops, allowing the controller to work with compatible motor feedback formats. The drive uses current rating code 300, design version 1, and function module 01/00 for compatibility within line series 02.
