Product Description:
The DKR03.1-W200N-BE32-01-FW is a digital intelligent AC drive controller produced by Bosch Rexroth Indramat and assigned to the DKR Drive Controllers series. Intended for multi-axis machining centers and handling equipment, the unit regulates servo and spindle motors through pulse-width-modulated power stages. It is part of line 03, is design version 1, and uses function module version 01 to match the electrical profile of Indramat drives. By combining current control and diagnostic logic in one housing, the device supplies closed-loop torque and speed control in industrial automation. This arrangement helps the controller respond quickly to load changes while maintaining stable axis behavior during programmed motion.
At a switching frequency of 4 kHz, the drive delivers a continuous current of 92 A, translating to a continuous mechanical output of 35 kW when paired with suitable motors. The power stage is fed by a three-phase mains supply of 3xAC 400 … 480 V ±10%, while internal electronics are supported by a control supply of AC 230 V ±10%. Motion commands enter through the SERCOS interface, allowing deterministic cycle times and consistent parameter exchange. Digital servo and resolver feedback channels are present, so the controller can evaluate either encoder class without external converters. The type code carries a current rating of 200 A for the output bridge.
Peak demands such as acceleration are handled with 141 A of momentary output, and because the DC link is rigid and no bleeder or brake chopper is installed, excess regenerative energy must be managed at the system level. Thermal management is provided by a built-in air blower, which expels up to 1200 W of heat generated by the IGBTs and auxiliary circuits. The assembled unit weighs 49 kg and mounts directly into the cabinet on guide rails. The guide-rail format supports installation in cabinet layouts used for high-power drive sections. The available feedback channels let the same controller platform work with more than one motor feedback format.
