Product Description:
Bosch Rexroth Indramat manufactures the DKR02.1-F300N-BE84-01-FW, a member of the DKR Drive Controllers series. This digital intelligent AC drive controller governs high-torque servo motors in production lines, providing precise speed and torque regulation for demanding motion axes. The unit is part of Line 02, uses design version 1, and carries function module version 01. It operates without an internal brake chopper or bleeder, so regenerated energy must be handled elsewhere in the system, and its mass of about 104 kg suits fixed cabinet installation. That arrangement is common in multi-axis systems that use centralized energy management for regenerative events.
The command layer is handled through a SERCOS interface, allowing deterministic communication with motion PLCs while also accepting digital servo and resolver feedback from the connected motor. At a 4 kHz switching frequency, the drive supplies a continuous armature current of 141 A and can support up to 55 kW of axis output under the proper motor match. The power stage operates from 3xAC 400 ... 480 V ±10%, while the control electronics use a separate AC 230 V ±10% supply. Keeping the control circuit separate helps communication and logic functions remain stable when load-related disturbances appear on the main supply. Closed-loop feedback lets the controller correct speed deviations quickly during changing load conditions and rapid reversals.
Thermal management relies on liquid cooling, so the cabinet must include a closed coolant loop capable of removing 1800 W of waste heat from the controller. The inverter section carries a current rating of 300, and short acceleration events can draw up to 212 A before current limiting becomes necessary. This cooling method reduces the dependence on cabinet airflow around the heat sink and shifts heat removal to the machine's coolant circuit. With the cooling load handled by the liquid path, the controller can support sustained operation on high-demand axes without relying on large internal fans.
