R911289195
Product R911289195 (RAC 2.3-250-380-LP0-Z1) is a main spindle drive controller developed by Bosch Rexroth Indramat. Engineered to provide superior control to 2AD asynchronous main spindle motors and 1MB frameless spindle motors, its continuous motor power output ranges from 30 to 52 kilowatts. Equipped with a motor feedback cable, it ensures wide speed range, precise shaft control, and high stiffness for the attached servo motors. With a high-resolution capacity of 1/4 000 000th of a revolution, it facilitates control even at hardly noticeable speeds. It’s ideally suited for Computer Numerically Controlled (CNC) machines.
The R911289195 (RAC 2.3-250-380-LP0-Z1) controller includes three electrical connections - power, motor feedback/CNC, and controller-specific connections. These connections allow interaction with the main electric supply, digital signal exchange with the servo motor and control center, and signal transmission within the controller housing. The controller includes a heat sink and a fan for internal temperature regulation. The flowing air absorbs excess heat and is expelled through the air silts. The R911289195 (RAC 2.3-250-380-LP0-Z1) controller operates at a rated voltage of 3 x AC 400 Volts, a power frequency of 50 to 60Hertz, and generates a continuous controller output of 65 kilowatts and a peak of 78 kilowatts. The controller weighs around 121 kilograms.
