KDA 2.1-050-3-LYS-W1

The Bosch Rexroth Indramat KDA 2.1-050-3-LYS-W1 is a robust member of the KDA Spindle Drives series, engineered by Bosch Rexroth Indramat for demanding CNC and precision machining applications. With a Rated Current of 50 A and a DC Bus Voltage of 300 V, this main spindle drive delivers high stiffness and continuous power across an extensive speed range. Designed to ensure precise positioning and reliable torque delivery, it excels in scenarios where tight tolerances and rapid acceleration are critical.

Leveraging a SERCOS speed command interface, the drive integrates seamlessly with modern automation networks, while the auxiliary encoder input (synchronous) and auxiliary interface (RS-232C) provide versatile feedback and communication paths. Forced cooling via a heatsink blower, powered at 220 VAC, maintains optimal thermal conditions under heavy loads, ensuring continuous operation and preventing thermal overload. The unit’s design version 1 and product series KDA designation underscore its adherence to established engineering standards and its place within a proven drive family.

Built for longevity and efficiency, the KDA 2.1-050-3-LYS-W1’s forced cooling method and robust heatsink blower design enhance heat dissipation and minimize maintenance intervals. Compatibility with SERCOS network protocols ensures streamlined integration into diverse control architectures, while the synchronous encoder input supports high-resolution feedback for enhanced motion accuracy. With its durable construction and precise control capabilities, this spindle drive delivers improved throughput, reduced cycle times, and consistent performance in industrial environments, offering significant benefits in energy efficiency and system reliability.
