KDA 3.1-150-3-LQS-U1

The Bosch Rexroth Indramat KDA 3.1-150-3-LQS-U1 drive is a high-performance member of the KDA Spindle Drives series, designed for precision spindle control in demanding industrial settings. Manufactured by Bosch Rexroth Indramat, this main spindle drive delivers a Rated Current of 150 A and operates on a DC Bus Voltage of 300 V, ensuring robust power delivery and stability. Its primary function is to provide continuous, high-stiffness torque for spindle applications, combining dynamic speed control with reliable positioning capabilities.

This drive incorporates advanced technical features to support seamless operation in automated systems. The heatsink blower is powered by an AC Supply Source for Heatsink Blower of 115 VAC, delivering effective forced cooling for thermal management under heavy loads. An Aux. Encoder Input supports 1 V sinusoidal signals, enhancing feedback resolution and accuracy for precise motion control. Communication is facilitated through a Serial Interface RS 232 C, while the Speed Command Value is managed via a SERCOS - Interface, enabling synchronous data exchange with CNC and PLC controllers.

Engineered for durability and efficiency, the KDA 3.1-150-3-LQS-U1 drive benefits from forced cooling by heatsink blower to maintain optimal operating temperatures and extend service life. Its compatibility with industry-standard SERCOS protocols and RS 232 C interfaces ensures straightforward integration into existing automation architectures. The sturdy design and consistent performance under continuous power conditions make this drive well suited for high-speed machining, milling, and turning centers. In industrial applications, it delivers precise spindle speed regulation, reduced downtime, and improved process reliability, driving productivity to new levels.
