KDA 3.1-100-3-L0I-U1

The Bosch Rexroth Indramat KDA 3.1-100-3-L0I-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision spindle control with a Rated Current of 100 A and a DC Bus Voltage of 300 V for robust performance. This design 1 unit integrates a Product: KDA platform and Series 3 architecture, ensuring consistent mechanical and electrical footprints across installations. The drive’s Speed Command Value: SERCOS - Interface enables deterministic communication and tight loop acceleration. Forced heat management is handled via a dedicated heatsink blower rated for an AC Supply Source for Heatsink Blower of 115 VAC, maintaining optimal junction temperatures even under sustained loads.

High stiffness and advanced positioning features define the KDA 3.1-100-3-L0I-U1, supporting complex contouring and rapid acceleration profiles with continuous power delivery. Cooling is achieved through Forced Cooled by Heatsink Blower technology, which circulates air directly over critical power electronics to prevent thermal derating. An Aux. Encoder Input: Without simplifies cabling when external feedback is unnecessary, while the Aux. Interface: Incremental Encoder Output provides real-time position data for downstream controllers or monitoring systems. The drive accommodates high dynamic demands and compensates for torque ripple, making it ideal for high-precision machining centers and automated production lines.

Integration into modern CNC and motion platforms is streamlined through a standardized connector layout and software support for SERCOS-based parameterization. Built-in safety functions and fault diagnostics enable rapid troubleshooting, reducing downtime during maintenance. With its combination of 100 A current capacity, 300 V DC bus, and SERCOS communication, the KDA 3.1-100-3-L0I-U1 spindle drive stands out as a reliable, high-performance solution for demanding spindle applications.
