KDA 3.2-100-3-L0D-U1

The Bosch Rexroth Indramat KDA 3.2-100-3-L0D-U1 from the KDA Spindle Drives series houses a robust spindle drive architecture built for precision and endurance. It features a Rated Current of 100 A and a DC Bus Voltage of 300 V, ensuring stable power delivery across extensive operating ranges. High stiffness and advanced positioning capabilities are enhanced by a Speed Command Value via SERCOS – Interface, while integration is streamlined through a Position Command Value Digital 16-Bit Parallel Aux. Interface. The unit’s underlying Design 2 product topology delivers consistent performance under varying loads.

The drive’s thermal management relies on a Forced Cooled by Heatsink Blower approach, leveraging an AC Supply Source for Heatsink Blower of 115 VAC to maintain optimal junction temperatures during continuous operation. Its compact footprint accommodates the Series 3 form factor without compromising on heat dissipation, and the absence of an Aux. Encoder Input further simplifies installation in space-constrained cabinets. Built on the proven KDA platform, the drive integrates seamlessly with standard SERCOS networks and supports direct digital positioning through the parallel interface. Protection features within the product ensure reliable motor control under dynamic spindle loads, reducing risk of thermal shutdowns and prolonging service intervals.

Optimized for milling, drilling, and grinding applications, this spindle drive achieves precise speed regulation and rapid response through its high‐resolution command interfaces. Maintenance is expedited by the modular design of the KDA family, which enables quick replacement of blower modules and power electronics. With its combination of robust electrical ratings and advanced control features, the KDA 3.2-100-3-L0D-U1 is ideally suited for high-performance machine tool spindles requiring reliable, repeatable operation.
