Product Description:
The DKR02.1-W200N-BE92-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the DKR Drive Controllers series. Designed for multi-axis machining and handling systems, the unit converts three-phase mains power into a regulated DC link and controlled output for large induction or synchronous servomotors. It serves as the central axis regulator, executing velocity and position loops while exchanging status data with higher-level automation equipment. This arrangement allows the controller to manage demanding axis motion while maintaining stable regulation during rapid load changes.
The drive receives motion commands through a SERCOS interface, allowing deterministic fiber-optic communication with CNC or PLC masters. At a switching frequency of 4 kHz, the power stage delivers a continuous output of 120 A, translating to approximately 47 kW of usable mechanical power for connected motors. Thermal stability is maintained by forced air cooling from an integrated blower, and the control electronics are energized by a separate AC 230 V supply that can fluctuate by ±10% without functional loss. A rigid DC bus design is used, and because no brake chopper is installed, regenerated energy must be managed externally. Resolver and digital servo feedback inputs support both legacy and high-resolution encoders.
During acceleration or disturbance rejection, the converter can supply up to 141 A in short bursts, while its power section is rated for mains of 3x AC 400-480 V ±10%. Internal losses appear as heat, and the enclosure expels approximately 1600 W, so cabinet airflow must remove that thermal load during sustained operation. The unit is part of line 02, design version 1, and function module 01. All components are contained in a single frame that weighs about 104 kg, which reflects the size of the power hardware and cooling assembly. That mass requires solid cabinet mounting and sufficient support around the installation point.
