The R911261561 (RAC 2.3-200-380-AY0-W1) is an AC main spindle drive controller intended for Rexroth Indramat AC spindle motors, commonly utilized in CNC machine applications. It offers a position control loop with a resolution of 1/4,000,000 revolutions, supporting precise speed and positioning control. The unit operates on a 3-phase 400V AC supply at 50-60 Hz, with a rated current of 200 A and peak current up to 300 A. It meets F class protection requirements per DIN 40 040, supporting 70% humidity and operating temperatures up to 45°C. Cooling is managed by an internal blower. The controller features analog speed command input (+/- 10 V), additional encoder and synchronous input, supports incremental encoders, and provides spindle feedback via a 9-pole X4 interface terminal. It is part of the RAC 2 series, version 3 design code, and is intended for installation in a control cabinet due to its non-waterproof construction.
