The Bosch Rexroth MPN R911256094 (RAC 3.5-150-460-APD-W1-220) is an AC main spindle drive controller designed for operation with INDRAMAT 2AD asynchronous main spindle motors and numerically controlled machine tools. It operates with a rated connection voltage of 3 x AC 400 V (50 Hz, ±15%) or 3 x AC 460 V, and a rated current of 150 A. The drive features an internal blower for cooling, frameless spindle motor support, and continuous output power between 10 and 30 kW. Positioning is managed by an internal control loop with 1/4,000,000th revolution resolution and a high-resolution INDRAMAT encoder. Interfaces include a 16-bit digital position set-point input (X4, 9-pole terminal) and an additional encoder input for spindle feedback. The device is classified as series 3, version 5, with an analogue speed command input of ±10 V. It is suitable for installation at altitudes up to 1000 m and in ambient temperatures ranging from 5 to 45°C (absolute max 55°C), and provides IP10 protection.
