The Bosch Rexroth drive controller R911298615 (DKR04.1-W300N-BT29-01-FW) is engineered for precision control of servo motors, featuring modular expandability through auxiliary plug-ins, software modules, and command interface cards. It incorporates an integrated contactor and emergency stop shutdown device, and supports external brake resistors for mains failure scenarios. The unit uses air cooling with an integral heat sink and blower, configurable for internal or external cabinet cooling. It supports SERCOS interface command, accommodates digital servo and resolver feedback, and is designed for reliable signal transmission up to 75 meters under magnetic or high-frequency interference. The drive operates with a nominal current of approximately 300A, without a brake chopper or bleeder, and is rated for temperatures from +5°C to +45°C and altitudes up to 1000 meters. Suitable for NC-controlled machine tool and printing machine applications.
