Product Description:
The DKR02.1-W200N-BE12-00 drive belongs to the DKR Drive Controllers series manufactured by Bosch Rexroth Indramat. It is a digital intelligent AC drive controller designed to provide high-performance vector control for large synchronous and asynchronous motors used in industrial automation. By receiving real-time setpoints from CNC systems or PLCs, the unit converts DC bus energy into controlled three-phase output for coordinated axis movement and rapid spindle acceleration in machining centers, robotic cells, and transfer lines.
At a switching frequency of 4 kHz, the drive can deliver a continuous output current of 120 A, which corresponds to a sustained shaft power of approximately 47 kW when it is matched with a compatible motor. Short-term overloads are supported by a peak current reserve of 141 A, giving additional margin during acceleration and cutting shock events. Logic and relay circuits are energized from a separate AC 230 V ±10% control supply, while the power stage is fed by a three-phase mains supply of 3× AC 400 to 480 V ±10%. The internal current rating code of 200 refers to the converter section and bus bars for 200 A thermal loading, and the unit is Line 02 with design version 1 and function module version 00.
Communication with the motion controller takes place over the SERCOS interface, and position information is returned through digital servo and resolver feedback channels to close the control loop. Thermal management relies on a built-in air blower, and the forced airflow removes up to 1600 W of waste heat generated by IGBT switching losses and bus resistance. Because of its integrated fans and large aluminum heat sink, the unit weighs approximately 104 kg, so the mounting panel must support substantial mass. The drive uses a rigid DC bus and does not include a brake chopper, which helps keep cabinet wiring straightforward.
