The Indramat R911248451 (RAC 4.1-400-460-A0I-W1) is an AC main spindle drive controller designed for asynchronous main spindle motors, featuring high rigidity and an internal automatic position control loop that can be operated with either motor or spindle feedback. It offers a speed command interface via analogue +/-10 V, supports configuration through a built-in control panel, and stores parameters on a programming module. The controller operates at a rated current of 400 A with a connection voltage of 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V, and provides cooling via an internal blower. Key interfaces include a digital position input (up to 3600 positions), an incremental encoder output, a serial parameter interface, and a 9-pole X4 terminal. No additional encoder input or external bleeder is present in this version.
