The Bosch Rexroth drive controller R911298428 (DKR02.1-W300N-BT72-02-FW) is engineered for precise positioning and speed control in industrial applications such as printing, woodworking, textile production, metal machining, and paper processing. It supports motor types including 2AD asynchronous, 1MB frameless, LSF, and LAR linear motors, utilizing a closed-loop feedback system with digital servo or resolver feedback for accurate control of rotor position. This controller features a nominal current rating of approximately 300A and an air cooling method via a built-in blower. Its command interface uses the SERCOS protocol, and expansion is possible through additional modules and plug-in cards. The device incorporates a built-in brake resistor to manage heat during motor deceleration and operates optimally within a temperature range of 5°C to 45°C. The bleeder configuration is without a brake chopper and features a rigid DC bus.
