The Indramat R911277264 (RAC 2.3-150-460-A0I-W1) is a main spindle drive controller from the RAC 2 series, designed for digital control of compatible Indramat motors such as the 1MB frameless spindle models. This unit supports a rated connection voltage of 3 x AC 400 V, 50 Hz, ±15% or 3 x AC 460 V, and delivers a rated current of 150 A. It uses an internal blower and built-in fan for cooling, with heat dissipation facilitated by a heatsink and air slits. Cooling air can be sourced from control cabinet inside or outside air, depending on the mounting configuration. The controller provides incremental encoder output via a 9-pole X4 interface terminal, accepts analogue speed commands (±10 V), does not include an additional bleeder, and lacks an additional encoder input. This version is designated as series 2, version 3.
