DKR03.1-W200N-BE29-02-FW

The Bosch Rexroth Indramat DKR03.1-W200N-BE29-02-FW from the DKR Drive Controllers series is a high-performance drive controller designed for the precise regulation of Rexroth Indramat spindle motors. This Product Series DKR unit delivers a Rated Current (A) of 200 and adheres to Line Series 03 specifications, while a Design Version 1 architecture ensures long-term reliability. Equipped with robust digital control logic, the controller integrates both digital servo and resolver feedback for unparalleled motor positioning accuracy. Its advanced built-in blower cooling method provides efficient heat dissipation during continuous operation.

The controller accepts a three-phase mains input of 3xAC 400-480 V AC (±10%) at an operating frequency of 50…60 Hz, and utilizes a dedicated control voltage of 230 V AC (±10%) with a control power rating of 200 VA. Communication is handled via the certified Command Interface SERCOS, guaranteeing low-latency data exchange for synchronized multi-axis applications. The unit’s Bleeder Configuration: No bleeder/Without brake chopper, rigid DC bus ensures a stable DC link, while an integrated mains contactor and emergency shutdown device meet stringent safety requirements. All electrical connections and interfaces conform to industrial standards for field-proven robustness.

Rated for continuous duty within an ambient temperature range of 5 – 45 °C (100% load) and up to 55 °C at reduced load, the controller can be installed at up to 1000 m above sea level, with a storage and transport temperature tolerance of –30 to +80 °C. Its IP20 protection rating per IEC529/EN60529 safeguards internal electronics from inadvertent contact in clean industrial environments. Weighing approximately 49 kg, the DKR03.1-W200N-BE29-02-FW must be handled and serviced by certified personnel to maintain warranty coverage and ensure safe operation.
