KDA 2.1-100-3-LQI-U1

The Bosch Rexroth Indramat KDA 2.1-100-3-LQI-U1 spindle drive from the KDA Spindle Drives series is engineered for high-performance machining applications. As a main spindle drive, it delivers a Rated Current of 100 A and operates on a DC Bus Voltage of 300 V, ensuring robust torque delivery and dynamic acceleration. Equipped with a Speed Command Value via a SERCOS interface, this drive excels in precision positioning and high-speed versatility, making it ideal for CNC milling, turning, and drilling spindle control.

Incorporating advanced technical design, the KDA 2.1-100-3-LQI-U1 utilises a forced cooling system driven by a Heatsink Blower powered from 115 VAC. It features an Aux. Encoder Input for 1 V sinusoidal encoder signals and an Aux. Interface providing incremental encoder outputs for exact feedback loops and streamlined motion control. The drive’s integral design supports continuous power delivery and extended operational cycles, maintaining thermal stability and consistent performance under heavy loads. Unique to this model is its combination of high stiffness and extensive speed range, enabling rapid acceleration and deceleration without compromising positional accuracy.

Beyond core power and control specifications, the KDA 2.1-100-3-LQI-U1 offers broad compatibility with industry-standard SERCOS networks, facilitating seamless integration into modern automation systems. Its forced-air heatsink blower cools critical components efficiently, enhancing durability and reducing downtime due to thermal stress. The drive’s precision encoder inputs further improve system responsiveness and reduce mechanical wear by minimizing overshoot and oscillation. In industrial settings, users benefit from simplified commissioning, reliable continuous operation, and precise spindle speed management, ultimately increasing throughput, reducing cycle times, and ensuring consistent product quality.
