Product Description:
The DKR02.1-W200N-BE23-01-FW drive controller is built by Bosch Rexroth Indramat and belongs to the DKR Drive Controllers series. As a digital intelligent AC drive controller, it regulates motor current for high-power servo axes used in machining centers and handling systems. This allows the connected motor to follow commanded torque and speed with stable response during acceleration, deceleration, and position-controlled movement. The unit is intended for applications where a centralized controller coordinates demanding axis motion over an industrial drive network.
In operation, the controller exchanges motion commands over a SERCOS interface, allowing deterministic communication with CNC or PLC hosts. At a switching frequency of 4 kHz, it delivers a continuous output current of 120 A, which corresponds to approximately 47 kW of sustained mechanical power when paired with a compatible Indramat synchronous motor. Low-power electronics are supplied through a control circuit rated at AC 230 V, ±10%, while heat is removed by a built-in air blower. For short acceleration bursts, the inverter can source a peak phase current of 141 A, which helps support rapid ramp-up under temporary overload conditions.
The power section accepts mains in the range of 3 x AC 400 to 480 V, ±10%, matching common industrial three-phase supplies. During full-load operation, the semiconductors and magnetic components release about 1600 W of heat, so the enclosure must allow enough airflow and clearance around adjacent modules. The unit has a mass of approximately 104 kg, so lifting equipment is usually needed during mounting. The DC bus is specified without a bleeder or brake chopper, so regenerated energy must be handled by external equipment. It also processes digital servo and resolver feedback, and the unit is design version 1 with function module version 01.
