The R911282408 (RAC 2.3-250-380-LQ0-W1) is an AC main spindle drive controller engineered for precise digital control of Indramat 2AD asynchronous and 1MB frameless spindle motors in industrial automation systems. It supports three-phase input at 400 V, 50-60 Hz, and delivers a rated current of 250 A. The device achieves a high positioning resolution of 1/4,000,000 of a revolution, which enables accurate shaft position and low-speed control required in CNC applications. Cooling is managed by an internal blower; the controller unit weighs 121 kg and is rated IP10. Interface connections include terminal X4 with optical waveguides, and speed command is received via the SERCOS interface with an available 10V speed set-point. No additional bleeder is fitted.
