The R911246837 (RAC 4.1-300-460-A00-W1) is an AC main spindle drive controller designed for digital control of frameless spindle and asynchronous main spindle motors. Operating with a rated connection voltage of 3 x AC 400 V, 50 Hz, ±15% or 3 x AC 460 V, it provides a rated current of 300 A and a continuous output power of 60 kW. The unit incorporates an internal blower for cooling, a control panel with display and keypad, a Q1 switch, and utilizes analogue (±10 V) speed command. The controller requires 80 mm clearance at the top and bottom and uses M12 screws for earthing and power connections at the base. It weighs 150 kg with an additional 4 kg assembly frame. Connections are provided via X4, 9-pole interface terminal, and it does not include an additional bleeder or encoder input. The device conforms to applicable safety standards and must be stored in dry, dust-free conditions within a -30°C to +85°C temperature range.
