Product Description:
The DKR02.1-W300Z-BE32-01-FW drive controller is produced by Bosch Rexroth Indramat within the DKR Drive Controllers series. It belongs to the Digital Intelligent AC Drive Controller product group and serves as the central power and control unit for large synchronous or induction motors in automated machinery, converting line power into regulated three-phase output while exchanging real-time status data with supervisory PLCs. In operation, it regulates motor torque and speed so heavy-duty axes can follow commanded motion profiles. This makes it suitable for high-power motion tasks in automated production equipment.
This model uses the SERCOS interface as its command layer, enabling deterministic fiber-optic communication with multi-axis motion systems. The power stage accepts a rated supply of 3 x AC 400 to 480 V ±10%, while internal logic and I/O are supported by a separate control voltage of AC 230 V ±10%. Under a switching frequency of 4 kHz, the drive can deliver a continuous armature current of 141 A, translating to roughly 55 kW of output to the connected motor. For short acceleration bursts, the peak current rises to 212 A, which matches the unit’s 300 current rating code. Motor feedback channels accept both digital servo signals and resolver data, allowing flexible pairing with Rexroth MKD, MHD, or 1MB motor families. Built-in diagnostics track temperature, inverter status, and bus voltage to protect the power semiconductors and connected mechanics.
Thermal management is achieved through a built-in air blower that moves air across the heat sinks, limiting internal losses to 1800 W under nominal load. With a transport mass of 104 kg, the controller requires cabinet reinforcement and careful handling during installation. The unit is design version 1, function module version 01, and line series 02.
