Product Description:

The DKR03.1-W200Z-BE30-01-FW is an AC drive controller manufactured by Bosch Rexroth Indramat for the DKR Drive Controllers series. It serves as the power and regulation stage for high-capacity servo and spindle motors used in automated machinery. It is used where the drive must regulate torque, speed, and axis response for demanding production equipment. The designation includes line 03, current rating W200, design version 1, and function module version 01, identifying the unit version used for heavy-duty motion control.

Communication with the automation system takes place over the SERCOS interface, enabling cycle-synchronous command exchange and diagnostic reporting. The power section is supplied from 3 x AC 400 to 480 V, ±10% mains power, and at a switching frequency of 4 kHz the drive sustains a continuous output of 92 A. Under these conditions, it can transmit about 35 kW of mechanical power to the connected motor. For short acceleration or braking bursts, the current reserve rises to a peak of 141 A, supporting high torque demand without immediate overcurrent shutdown. Digital servo and resolver feedback channels allow the controller to close position and velocity loops across a broad operating range.

Ancillary electronics are energized by an AC 230 V, ±10% control supply, which feeds the logic circuits, sensors, and cooling hardware. This separate supply supports the controller functions needed for monitoring and internal operation. Thermal management relies on a built-in air blower to remove junction heat, and during full-load operation the device releases about 1200 W into the cabinet environment. Mechanical planning must account for a mass of approximately 49 kg, and mounting frames should maintain clear airflow paths to the intake and exhaust grilles. Proper cabinet ventilation is necessary for stable operation under sustained load.
