The Bosch Rexroth R911256142 (RAC 2.3-200-460-APD-W1) is an AC main spindle drive controller engineered for digital control of 1MB and 2AD series motors in numerically controlled machine tools. It supports a rated connection voltage of 3 x AC 400 V at 50 Hz (±15%) or 3 x AC 460 V and delivers a rated current of 200 A. The device integrates an internal blower for cooling and accepts digital position set-points through a 16-bit parallel interface, with speed command available via analogue input (±10 V). Key connections—motor fan, supply, and power—are positioned at the unit's base, and a high-resolution Indramat encoder interface is provided for spindle feedback via X4 (9-pole connector). Operating temperature is specified from 5°C to 45°C. The unit’s configuration requires appropriate lifting equipment due to its weight and technical servicing only by qualified personnel.
