KDA 2.1-100-3-L0I-W1

The Bosch Rexroth Indramat KDA 2.1-100-3-L0I-W1 main spindle drive from the Bosch Rexroth Indramat KDA Spindle Drives series delivers precision motion with high stiffness, robust construction, and optimized thermal performance. Engineered to sustain continuous power output, it ensures reliable operation in demanding high-speed machining and drilling applications. The unit supports a Rated Current of 100 A and a DC Bus Voltage of 300 V to drive heavy-duty spindles with consistent torque and speed. Compact yet powerful, this drive integrates advanced positioning features for accurate tool engagement and minimal downtime.

Designed for seamless integration, the KDA 2.1-100-3-L0I-W1 employs forced air circulation with Cooling provided by a heatsink blower powered via an AC Supply Source for Heatsink Blower of 220 VAC, maintaining optimal junction temperatures. A dedicated incremental Aux. Interface delivers high-resolution feedback, while the Aux. Encoder Input configured as Without allows straightforward connection to external sensors. Command inputs utilize a Speed Command Value through the SERCOS - Interface, affording deterministic, real-time communications across multi-axis networks. The drive’s Design rating of 1 and Series designation of 2 within the Product portfolio underscores its industrial-grade durability and standardized compatibility.

Engineers benefit from the unit’s plug-and-play SERCOS connectivity and forced-cooling reliability, which minimize installation complexity and maintenance intervals. The KDA 2.1-100-3-L0I-W1’s adherence to Bosch Rexroth Indramat quality standards ensures consistent performance and protection against thermal overload. Ideal for CNC lathes, milling centers, and high-precision grinding machines, this spindle drive offers enhanced uptime and precise torque delivery in critical production environments.
