The Bosch Rexroth MPN R911277360 (RAC 2.3-200-460-A0S-W1) is an AC main spindle drive controller from the RAC series, design version 3. It supports a rated connection voltage of 3 x AC 400 V at 50 Hz (±15%) or 3 x AC 460 V, with a rated current of 200 A and current type up to 300 A. The controller features a closed-loop system with internal position loop and supports feedback from spindle or motor. Its modular design includes an internal blower for cooling, a built-in heatsink, and an RS 232-C serial interface. Mounted vertically in a control cabinet, it operates in ambient temperatures up to 55 °C in accordance with DIN VDE 0160. Electrical connections include X4 (9-pole interface terminal), a connection for an NTC motor resistor, and an analog (+/-10 V) speed command input. No additional bleeder or encoder input is present.
