The Bosch Rexroth R911267129 (KDA 3.3-150-3-D00-W1) Main Spindle Drive belongs to the KDA product group, designed to control frameless spindle and asynchronous motors digitally. It features a modular structure with coded series and design. Parameterization allows its compatibility with various operating modes and motors. The drive operates at a bus voltage of 300VDC with a rated current of 150A and uses forced cooling type cooling mode. Designed to operate optimally between 5°C and 45°C, the device complies with the Class F peak humidity as per DIN 40 040 specifications. The front view reveals a stay bolt with a hexagon socket on top. Note that during installation, the unit must always be vertical with grounding bolts on top. While it lacks an auxiliary encoder input or interface, it mandates ground connections to both the supply module and motor. It is transport-safe unloaded and supported by a one-year warranty.
