The Bosch Rexroth R911268093 (DKR02.1-W300Z-BE12-01-FW) is a drive controller from the DIAX04 DKR series, engineered for precise control of AC main spindle motors, 1 MB frameless motors, and linear motors. It supports high-dynamics and wide speed range operation. The controller supports integration via an RS-232 interface and a SERCOS command interface, with module customization through plug-ins. It operates at a supply voltage of 3 x 400–480 V, system frequency 50–60 Hz, and accepts power voltage up to 380 V. Motor temperature monitoring is included. Air cooling is facilitated by a built-in blower. The maximum current rating is approximately 300 A, and the integrated bleeder resistor can dissipate up to 90 kW. The product features IP20 ingress protection and functions at ambient temperatures up to +55°C. Digital servo and resolver motor feedback is supported.
