The Indramat MPN R911238161 (RAC 2.2-250-380-A0S-W1) is an AC main spindle drive controller engineered for pairing with high current control servo motors such as Indramat 2AD and 1MB, primarily used in CNC and other industrial machinery. It integrates a closed-loop control system for precise spindle positioning per software commands. The unit operates at a rated connection voltage of 3 x AC 400V (50-60Hz) or 3 x AC 460V, with a rated current of 250 A. Cooling is managed via an internal blower and built-in fan, with optional cooling hose integration. The controller supports a continuous output of 65 kW and a peak power output of 78 kW, and can function in ambient temperatures up to 55°C. The device features a serial RS 232-C interface, an analogue speed command input (+/- 10 V), and an X4 9-pole interface terminal. Weight is approximately 121 kg. Additional bleeder and additional encoder input are not included.
