The Bosch Rexroth R911277221 (DKR02.1-W300Z-BE11-02-FW) model provides modern motion control equipment such as drive controllers, servo motors, and frequency converters. The DKR02.1 drive controller, which observes an IP20 protection standard, must be operated in a dust-free environment and in a closed control cabinet of at least IP54 category. Used primarily in machine tools, printing machines, and handling systems, the controller comprises a power rectifier, five PCI slots, and a DSS 02.1M command interface card for indirect position detection. For communication purposes, it uses optical fiber cables for real-time interaction with AC motors via the SERCOS interface.

With a maximum braking energy of 240 kWs, it requires a 24VDC blower for cooling and 300A of rated current. Firmware, sold separately, can be ordered based on configuration requirements. The unit comes with a global one-year warranty from Indramat USA.
