KDA 3.2-100-3-DYS-U1

The Bosch Rexroth Indramat KDA 3.2-100-3-DYS-U1 drive is a high-performance spindle control solution in the KDA Spindle Drives series, engineered by Bosch Rexroth Indramat. It delivers a Rated Current of 100 A and operates on a DC Bus Voltage of 300 V, providing the power and stability required for demanding main spindle applications. With a broad speed range and continuous power rating, this drive is designed to manage high-stiffness positioning tasks and maintain consistent performance under variable loads. The primary function of the KDA 3.2-100-3-DYS-U1 is to precisely control spindle speed and torque in industrial machining centers, ensuring smooth acceleration and deceleration cycles.

Incorporating advanced control interfaces, this spindle drive features an Auxiliary Encoder Input capable of both auxiliary and synchronous encoder feedback, enabling precise position tracking and closed-loop control. The Speed Command Interface is a Digital 16-bit parallel input, offering high-resolution speed reference signals for ultra-fine speed adjustment. Cooling is managed via a forced-air system: a heatsink blower supplied at 115 VAC ensures efficient thermal regulation, maintaining optimal operating temperatures even under continuous high-load conditions. The drive’s compact design (Design 2) simplifies integration into existing machine frames while delivering robust performance.

Built for reliability and compatibility, the KDA 3.2-100-3-DYS-U1 supports an RS-232C serial auxiliary interface for diagnostics and parameter configuration, streamlining commissioning and maintenance processes. The forced-air cooling via heatsink blower enhances durability by preventing thermal overloads and extending component life. Auxiliary and synchronous encoder inputs ensure seamless interoperability with a wide range of spindle motors and control systems. In industrial environments where uptime and precision are critical, this spindle drive delivers exceptional efficiency, minimized heat buildup, and consistent torque delivery. By integrating the KDA 3.2-100-3-DYS-U1 into machining operations, manufacturers benefit from higher throughput, reduced cycle times, and improved overall equipment reliability.
