The R911256091 (RAC 3.5-100-460-A00-Z1-220) is an AC main spindle drive controller designed for use in ventilated enclosures, requiring a minimum of 160mm clearance above and below. It supports operation at ambient temperatures up to 45°C and at elevations up to 1,000 meters. This 49 kg controller utilizes a 3 x AC 400 V, 50 Hz, ±15% or 3 x AC 460 V supply, with control electronics rated at AC 230 V, 50-60 Hz. It features an internal blower (IP 24-rated fan) for integrated cooling, IP10 protection, a 100 A rated current, and a peak regeneration output of 26 kW for up to 5 seconds. The X4, 9-pole terminal provides an analog ±10 V speed command interface suitable for standard CNC applications. Additional bleeder circuitry is included for braking during mains voltage failure. Electrical connection types depend on selected functional options, and no additional encoder input is provided.
