The R911256153 (RAC 2.3-250-460-A0I-W1) is an AC main spindle drive controller engineered for controlling and monitoring the speed and position of 2AD and 1MB Indramat servo motors. It integrates an AS programming module for configuration to specific servo motor parameters and includes an internal blower and heat sink for natural convection cooling. The device operates on a rated connection voltage of 3 x AC 400 V, 50 Hz, ±15% or 3 x AC 460 V, with a rated current of 250 A. Continuous power output is rated at 65 kW, peaking at 78 kW, and it provides regeneration power stability between 48 kW and 78 kW for approximately 3 seconds during power interruptions. The controller measures approximately 121 kg and is not designed for environments above 55°C or altitudes exceeding 1000 meters. It features an incremental encoder output interface at terminal X4 (9-pole), an analogue speed command input (±10 V), and does not include an additional bleeder resistor or encoder input.
