Product description
A continuous current of 210 A at 4 kHz identifies the Bosch Rexroth DKR04.1-W400N-BE12-01-FW as a W400 version in the DIAX03-DKR04 series. The digital drive controller also carries material number R911275762. Its type code denotes air cooling with an integrated blower, current class 400, digital servo and resolver feedback, and SERCOS as the command communication. Function code is 12 and function version is 01; FW refers to the separately assigned firmware. Diagnostic indicators and connections are located at the front, while the software module occupies a dedicated slot in the assembly. The power supply is rated for three-phase 400 to 480 V AC at 50 to 60 Hz. The control electronics use 230 V AC with 300 VA. The W400 base unit supplies 210 A continuous current at 4 kHz and 150 A at 8 kHz. Peak current is 282 A. The corresponding continuous output is approximately 93 kW at 4 kHz or 66 kW at 8 kHz. Depending on switching frequency, the maximum output frequency extends to 800 or 1600 Hz. Total power loss reaches 2500 W at continuous current, of which 1800 W is dissipated through the air duct or cooling area. The integrated blower provides the airflow. The DKR04 assembly has IP20 and a rated ambient temperature range from +5 to +45 °C. Storage and transport temperatures range from −30 to +80 °C. The construction uses a control-cabinet format. The DKR04 base body measures approximately 1080 × 560 × 571 mm and weighs around 150 kg. The complete type code distinguishes this specific configuration from other DKR04.1-W400 variants.
