The R911251429 (RAC 2.2-250-460-D0I-W1) is an AC main spindle drive controller from the RAC series by Rexroth Indramat. It operates with a rated connection voltage of 3 x AC 400 V, 50 Hz ±15%, or 3 x AC 460 V, and a rated current of 250 A. The controller supports digital speed command via a 16-bit parallel interface and features an incremental encoder output. Cooling is achieved with an internal blower. It does not include an additional bleeder or additional encoder input. The unit is designed for a temperature range of +5°C to +45°C, with derated efficiency up to +55°C, and is suitable for storage from -30°C to +85°C at altitudes up to 1000 meters. It has a mass of 121 kg and uses a 25-pole X4 interface terminal.
