Product Description:
The KDA 3.2-150-3-L00-U1 spindle drive is produced by Bosch Rexroth Indramat as part of the KDA Spindle Drives series in Series 3 and Version 2. Installed in a multi-axis cabinet, the module conditions the shared DC bus into a controlled three-phase output for high-speed spindle motors used in machining centers and grinding stations. By processing velocity references from the control network, the unit delivers precise torque and speed regulation that is critical for surface finish and repeatable cycle times in industrial automation. Its cabinet-mounted format supports integration with other drive modules on the same power infrastructure.
The power stage is energized from a bus voltage of 300 VDC, and its continuous output capability is rated at 150 A, allowing it to drive large synchronous or induction spindles at nominal load. Thermal management relies on forced-air cooling through a mounted heat sink blower, and the blower is supplied by an auxiliary line of 115 V/50–60 Hz so the main DC circuit does not carry fan current. Speed references reach the drive over the fiber-optic SERCOS interface, enabling deterministic update cycles and straightforward cabinet wiring. This configuration omits any parallel fieldbus board, which keeps the control path focused on the primary communication channel.
The unit operates in ambient air from 5 to 45 °C, and installation is permitted up to 1000 m above sea level without additional cooling measures. Communication expandability is limited by the lack of an additional interface option, and feedback wiring is simplified by the lack of a second encoder input. These limits suit spindle axes that use a single feedback channel and centralized optical communication. In typical machine cabinets, that arrangement reduces signal-routing complexity and keeps the control layout straightforward.
