The Bosch Rexroth R911271217 (RAC 2.3-250-460-D00-W1) is a versatile spindle drive with numerous interfaces, delivering digital and analog set speed points for diverse controller connections. Its SERCOS interface allows real-time relay of various set points and values. Optimized for performance and accuracy, the controller AS programming module automatically adapts to the spindle motor. Furthermore, the drive's microprocessor-controlled function eliminates the need for initial readjustments. Additional features include a synchronised encoder input for achieving servo drive coordination with the main machine. Though the R911271217 (RAC 2.3-250-460-D00-W1) comes with a cooling device, alternate cooling methods can be implemented with necessary structural changes to the control cabinet. For safe operation, ensure the unit is off before making any connections or adjustments. Importantly, power cables should be twisted and the motor grounded on the controller before installing. The product, available globally from Indramat USA, comes with a one-year warranty.
