The R911256153 (RAC 2.3-250-460-A0I-W1), an advanced main spindle drive controller manufactured by Indramat, is meticulously designed to control and monitor the speed and position of 2AD and 1MB Indramat servo motors. These motors are identifiable by their considerable speed range, precision, mechanical rigidity, and extensive power output, rendering them particularly compatible with Numerically Controlled machines. The R911256153 (RAC 2.3-250-460-A0I-W1) comes with an AS programming module for adapting the drive controller to the specific servo motor. It incorporates an air blower and heat sink for internal temperature regulation through natural convection but lacks an ancillary bleeder resistor. It ensures a consistent power output of 65kw and a peak of 78kw under normal operation. With power interruption, the motor maintains a stable regeneration power of 48kw―78kw for approximately 3 seconds. The drive controller is not suitable for environments exceeding 55 degrees Celsius or located over 1000 meters above sea level. Weighing approximately 121kg, the unit is eligible for international shipping, and it also comes with a one-year warranty from Indramat USA.
