The R911267801 (DKR02.1-W300Z-BE05-01-FW) is a Bosch Rexroth DKR02.1 drive controller designed for precise operation of AC main spindle, frameless, and linear motors within industrial automation applications. It operates at a nominal current of approximately 300 A and connects to a 3-phase power supply rated at 400–480 V, 50–60 Hz. The unit includes a 1.8 Ohm brake resistor with a continuous dissipation capacity of 1.5 kW and utilizes ambient air cooling with a built-in blower, managing up to 1800 W of thermally dissipated energy during continuous use. The controller features five modular slots; U1 is equipped with a DSS 2.1M command interface (SERCOS), and U2 contains a DZF03.1 auxiliary module. It supports motor feedback via digital servo and resolver feedback and is designed for operation in environments from +5 °C to +45 °C. The protection class is IP20.
