Product Description:

The DKR02.1-W300Z-BE23-01-FW is a digital drive controller manufactured by Bosch Rexroth Indramat for the DKR Drive Controllers series. It provides closed-loop regulation of high-power servo axes in production lines, transfer presses, and gantry systems where rapid torque control and coordinated multi-axis positioning are required. The unit converts three-phase supply energy into controlled drive output for large motors while exchanging real-time commands with the automation host through an optical communication path. That arrangement lets the drive regulate torque, speed, and position in large automation cells that depend on synchronized axis motion.

A principal communication path is the SERCOS interface, which allows the controller to receive cyclic command data and diagnostics on the same optical ring used by neighboring drives. Thermal management relies on a built-in air blower, so the cabinet must provide a clear airflow path without requiring an external heat exchanger. The controller is rated for a continuous output of 300 A, which supports high-inertia loads and large motor demands in heavy-duty motion systems. Motor position signals are accepted through digital servo and resolver feedback, and the controller is identified as Design version 1. This combination allows the controller to operate with motors that use encoder-based feedback as well as motors that use traditional resolver signals.

The controller uses function numeric version 01, which is associated with its control parameter structure and diagnostic behavior. It is also part of Line 02, placing it within the second hardware line of this platform. These identifiers help distinguish the controller's build and control format without changing its role as a high-power servo drive. Because the unit combines high current capacity with optical communication and multiple feedback options, it fits demanding servo applications that place heavy loads on the drive stage.
