The R911256136 (RAC 2.3-250-380-A00-W1) is a Bosch Rexroth spindle drive controller engineered for precision operation of Indramat 2AD asynchronous and frameless spindle motors, supporting main spindle and c-axis control functions. It utilizes an analog speed command interface (+10 to -10 V) and delivers a rated current of 250 A from a three-phase AC 400 V, 50-60 Hz supply. The device supports a position control loop for high accuracy at low speeds, features an internal blower for cooling with IP24 protection, and is configured via the AS programming module for complex motion control demands. Compatible motor sizes include 2AD132 to 2AD225. The controller is designed to operate within ambient temperatures of 5 to 45°C and ensures proper function with cabinet air below 55°C.
