Product Description:

The DKR02.1-W300B-BE12-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the DKR Drive Controllers series. It forms the power stage between a plant supply bus and a large servomotor, converting motion commands from the central control system into regulated three-phase output for industrial presses, gantry axes, and metal-cutting machines. In automated equipment, it manages fast current control and fault monitoring so the higher-level PLC can focus on sequence logic and machine coordination. Its control section is intended for applications that require stable torque delivery, quick response to command changes, and dependable supervision during continuous production cycles.

An optical fiber link over the SERCOS interface carries setpoints and diagnostic data for synchronized multi-axis operation. The device provides a nominal armature current of 300 A, allowing it to support high continuous motor demand on large axes. Thermal management is handled by a built-in air blower that moves air across the heat sinks. Dynamic braking energy is dissipated because the controller is supplied with a bleeder, which helps limit DC-bus overvoltage during rapid deceleration. Position and speed signals are accepted as digital servo and resolver feedback, allowing compatibility with either high-resolution digital feedback or resolver-based motor feedback.

The unit is built as design version 1, which matches the first mechanical layout used for this controller type. It is assigned to line series 02, placing it within the second hardware line of the product range. The controller also uses function version 01, which identifies the corresponding control version for this model. This combination helps keep the module matched to the correct rack arrangement and supported option set in multi-axis systems.
