R911234782
The R911234782 (RAC 2.2-150-460-A00-Z1), a product of Bosch Rexroth Indramat, is a digital main spindle drive controller mainly designed for handling the Indramat 2AD asynchronous spindle motors. This highly adaptive controller can manage frameless spindle motors with an output range of 30 to 52 KW. Additionally, the R911234782 (RAC 2.2-150-460-A00-Z1) is capable of autonomously positioning the spindle in response to a signal, demonstrating outstanding control proficiency when low speeds are required by the position control loop. For effective heat management, the controller is equipped with an in-built cooling system through a heatsink fan.
Equipped with feedback, CNC control, and additional interfaces, the R911234782 (RAC 2.2-150-460-A00-Z1) offers a host of connection options. It even entertains the addition of another main spindle controller via the control voltage bus or link circuit connection. Multiple other interface options that include speed set-point interfaces, a digital position set-point input, and a serial interface also enhance the product's functionality. Designed to operate effectively in humid environments, provided the average relative humidity is less than 70%, the R911234782 (RAC 2.2-150-460-A00-Z1) has a protection class of IP 10 as per DIN VDE 0160 standards. The controller can withstand contact with solid objects, but not water. The interior of the control cabinet and cooling fan both meet stringent protection standards with classes IP 54 and IP 24, respectively.
