KDA 3.2-100-3-L0I-U1

The Bosch Rexroth Indramat KDA 3.2-100-3-L0I-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat combines precision engineering with robust power delivery, featuring a Rated Current of 100 A and a DC Bus Voltage of 300 V. This KDA design package (Design 2, Product KDA, Series 3) is tailored for high-performance spindle applications, integrating a SERCOS - Interface for speed command value and an AC Supply Source for Heatsink Blower of 115 VAC. Thermal management is assured through forced cooling by heatsink blower, maintaining optimal temperatures under continuous load. The drive’s electrical I/O architecture includes an Incremental Encoder Output auxiliary interface and operates without an aux. encoder input, simplifying installation and reducing wiring complexity.

Engineered for high stiffness and fine positioning accuracy, the KDA main spindle drive delivers extensive speed range with continuous power, making it ideal for precision machining centers and heavy-duty milling. The incorporated Aux. Encoder Input: Without specification streamlines system topology when third-party feedback is not required, while the Aux. Interface: Incremental Encoder Output supports closed-loop control when maximum dynamic response is needed. Forced cooling via heatsink blower ensures stable operation across the full voltage and current envelope, even during sustained peak loads. The SERCOS interface speed command value provides deterministic communication and rapid synchronization with higher-level motion controllers.

Compact yet robust, the KDA 3.2-100-3-L0I-U1 spindle drive integrates seamlessly into modular automation systems, offering a consistent mechanical footprint across the KDA series. Simplified commissioning is achieved through parameter cloning and streamlined wiring, minimizing downtime during maintenance or system upgrades. This drive is a reliable choice for manufacturers seeking a spindle solution that balances performance, thermal resilience, and high-precision motion control.
