The R911275412 (KDA 3.3-150-3-D0I-W1) is a Bosch Rexroth main spindle drive designed for 1MB and 2AD series motors, delivering continuous output between 3 and 22 kW at the shaft. The unit features digital control, monitoring, and diagnostics, including a high-resolution rotor position sensor. It supports precise internal position control and is optimized for C-axis operation and spindle positioning in numerically controlled machinery. The device utilizes a built-in heat sink and is designed for installation at altitudes up to 1000 meters above sea level. The accessible control panel includes READY and FAULT indicators. The drive draws 1.6 A at a +24 V load voltage and operates with a continuous current of 90 A, a rated current of 150 A, a rated connection voltage for the attached blower (AC 50–60), and a rated voltage of 300 V. It is classified with IP 10 protection and should only be used in environments free of condensation, as it affords minimal resistance to water ingress or deliberate penetration.
