KDA 3.3-150-3-LQD-U1

The Bosch Rexroth Indramat KDA 3.3-150-3-LQD-U1 is a high-performance component in the KDA Spindle Drives series, engineered as a main spindle drive for precision machining applications. It delivers a Rated Current of 150 A and operates on a DC Bus Voltage of 300 V, providing a broad speed range with continuous power output and high stiffness. Designed for use in demanding CNC and automated production lines, this drive excels at precise positioning and consistent torque delivery.

This drive implements advanced command and feedback interfaces to maximize performance and integration flexibility. The Speed Command Value is transmitted via a SERCOS - Interface, offering deterministic real-time communication and interoperability with modern automation controllers. An Aux. Interface provides a Position Command Value Digital 16-Bit Parallel input for direct, high-resolution position control, while the Aux. Encoder Input accepts a 1 V sinusoidal signal for accurate feedback synchronization. The drive is Forced Cooled by Heatsink Blower, ensuring optimal thermal management under continuous high-load operation.

Additional features underscore the drive’s compatibility and operational efficiency. The heatsink blower runs on an AC Supply Source for Heatsink Blower of 115 VAC, allowing straightforward integration into existing power systems. The robust cooling design reduces thermal drift and extends maintenance intervals, while the standardized SERCOS protocol guarantees seamless interoperability across multi-vendor networks. As a result, the KDA 3.3-150-3-LQD-U1 spindle drive enhances productivity, ensures consistent cycle times, and delivers reliable performance in industrial manufacturing environments where precision and durability are paramount.
