The Indramat R911259583 (RAC 4.1-400-460-LP0-W1) is an AC main spindle drive controller within the RAC 4 series. Designed for digital control of asynchronous main spindle motors and frameless spindle motors, the unit achieves resolution up to 1/4 000 000 revolutions. It operates with a rated connection voltage of 3 x AC 400 V, 50 Hz, ±15% or 3 x AC 460 V, and supports a rated current of 400 A. The drive features internal cooling via a built-in fan and is equipped with high-resolution Indramat encoder support and additional encoder input for advanced spindle feedback. An interface terminal (X4) utilizes optical waveguides, while speed commands are managed via SERCOS interface. Operating temperature is specified between +5°C and +45°C, not exceeding +55°C, and protection is classified as IP 10.
