Product Description:
Bosch Rexroth Indramat built the DKR02.1-W200N-BA05-01-FW as part of the DKR Drive Controllers series. It is a digital intelligent AC drive controller for high-power servo and spindle motors in automated machining centers, transfer lines, and similar installations. By converting fixed-frequency mains power into regulated three-phase output, the unit enables speed, torque, and positioning commands to be executed with closed-loop accuracy inside industrial automation cells.
The drive receives motion commands through an analog interface, while motor position is returned through digital servo or resolver feedback to close the control loop. Its continuous output current is 120 A at a 4 kHz switching frequency, which supports a continuous mechanical output of 47 kW when the connected power stage operates within thermal limits. Internal logic and I/O circuits are supplied from a separate AC 230 V control voltage so command and diagnostic functions remain active even when the main link is de-energized. The power section is designed for a mains window of 3×AC 400 … 480 V ±10%, allowing installation on common plant distribution networks without an isolation transformer. Line code 02, design version 1, and function module version 01 identify the unit in the series. The DC bus is rigid, and regenerated energy must be managed externally because the unit has no brake chopper.
A peak output of 141 A is available for short acceleration bursts before protective limits intervene. The built-in blower provides air cooling, and the drive has a heat dissipation rating of 1600 W for cabinet ventilation planning. With a mass of 104 kg, the unit requires a rigid mounting surface. Airflow direction and total thermal loading should be considered when the rigid DC link is paralleled with other converters on the same bus.
