The Bosch Rexroth drive controller MPN R911285171 (DKR02.1-W300B-BE56-01-FW) is a digital unit suitable for NC machine tools and various industrial automation applications. It features a built-in bleeder resistor for dissipating excess heat and offers overvoltage protection. The controller operates on a 0–380V power supply and supports continuous output currents of 141/110 A, generating a rated output power of 55/43 kW. The peak regenerated power is 93 kW for up to 10 seconds. For effective thermal management, a clearance of at least 160 mm is required above and below the controller. It supports direct connection to three-phase AC power, air cooling via a built-in blower, motor temperature and brake monitoring, and uses a SERCOS command interface with digital servo and resolver feedback. The unit operates within a temperature range of +5 °C to +45 °C.
