The R911289195 (RAC 2.3-250-380-LP0-Z1) is an effective main spindle drive controller, developed by Indramat. Suitable for use with Indramat's 2AD asynchronous main spindle motors and 1MB frameless spindle motors, the controller offers impressive power, ranging from 30 to 52 kilowatts. It achieves superior motor control by connecting to the servo motor using a motor feedback cable, offering a broad speed range, precise shaft control, and notable stiffness. An additional key feature of this controller is its high resolution - allowing control of servo motors even at exceptionally low speeds. The controller is ideal for computer numerically controlled machines due to its advanced design to relay and receive signals for optimal motor control. Further, the controller uses a heat sink and fan for temperature regulation. Operating at an average voltage of 3 x AC 400 volts and a power frequency of 50 to 60 Hz, the controller weighs around 121 kilograms. It comes with a one-year warranty from Indramat USA.
