KDA 2.1-050-3-LY0-U1

KDA 2.1-050-3-LY0-U1, Bosch Rexroth Indramat, KDA Spindle Drives kicks off this high-performance spindle drive tailored for precision machining. Engineered to deliver robust dynamic response and positioning accuracy, it leverages advanced control algorithms within a compact enclosure. The design emphasizes rigidity and thermal stability, ensuring optimal spindle stiffness under varying loads. Its integration-ready architecture simplifies installation in new or retrofit CNC applications.

In detailed specification, the drive features a DC bus voltage of 300 V, and a continuous Rated current of 50 A to support demanding drive loads. Forced air (heatsink blower) cooling ensures stable temperature management, with a dedicated Heatsink blower supply of 115 VAC driving the thermal module. Commanded via an industry-standard Speed command interface: SERCOS, it offers deterministic cycle times for complex multi-axis systems. Dual Aux encoder inputs: Auxiliary & synchronous enable high-resolution feedback, while the Auxiliary interface: None architecture reduces system complexity. Classified as Product: KDA series 2, it adheres to the series Series: 2 design platform with a compact Design: 1 footprint, balancing power density and serviceability.

The KDA 2.1-050-3-LY0-U1 integrates seamlessly into Rexroth motion-control ecosystems, delivering consistent performance in high-speed spindle applications. Its forced-air cooling and robust electrical design provide reliable operation across extended duty cycles. Ideal for precision tooling centers, milling spindles, and grinding machines, it elevates throughput and accuracy while minimizing downtime.
