The R911293520 (DKR02.1-W300N-BE45-01-FW) is a drive controller designed for precise regulation of AC main spindle motors such as 2AD or ADF, frameless spindle motors 1MB, as well as LAF or LSF linear motors. This unit supports SERCOS real-time communication for digitized information exchange within the servo system. The controller features digital servo and resolver feedback, a nominal current rating of approximately 300A, and operates at 230 V with a maximum power output of 93 kW. Physical dimensions are 1000 mm length and 400 mm width, with an increase of about 170 mm in length when using a cooling duct. Air cooling is implemented via a built-in blower. The design omits a bleeder and brake chopper, supports a rigid DC bus, and requires a minimum separation of 100 mm between power and feedback cables to prevent interference. Only qualified personnel should operate this equipment.
