The R911256136 (RAC 2.3-250-380-A00-W1) is a Bosch Rexroth spindle drive controller designed to operate Indramat 2AD asynchronous and frameless spindle motors. This drive is perfect for main spindle and c-axis drive control and can easily transition between operating modes. With its high precision position control loop, the drive guarantees accurate control at minimal speeds. The controller operates optimally within cabinet air temperatures below 55°C and an ambient temperature range of 5 to 45°C. Aside from its essential functions such as e-stop, spindle positioning, compensation, error reactions, and integrated safety, it features an analog speed command interface with an applicable voltage spectrum of +10 to -10. The R911256136 (RAC 2.3-250-380-A00-W1) stands out for its power regeneration capability and its efficient cooling system, combining internal and external air, ensured by a cooling fan with an IP 24 protection class. This drive, which is designed for a three-phase main supply system, provides 250 amps of type current and works best with 2AD132 to 2AD225 size range motors. Configuration via the AS programming module promises precision for high-requirement motion control applications. This unit comes with a one-year global warranty from Indramat USA.
