KDA 3.2-050-3-LQ0-U1

The Bosch Rexroth Indramat KDA 3.2-050-3-LQ0-U1 is a high-performance drive in the KDA Spindle Drives series designed for demanding spindle applications. This unit delivers a Rated Current of 50 A and a DC Bus Voltage of 300 V, ensuring robust, continuous power throughout its extensive speed range. Built around a proven Design 2 topology, the drive accommodates the Product KDA platform’s modular architecture for straightforward maintenance and scalable upgrades. Integrated stiffness and precision positioning features make it an ideal choice for high-dynamics milling, grinding, and lathe systems.

Reliability is reinforced through a forced cooling system driven by a Heatsink Blower and supported by an AC Supply Source for Heatsink Blower of 115 VAC, maintaining optimal temperatures under peak loads. The drive accepts feedback through an Aux. Encoder Input for 1 V sinusoidal encoders, enabling high-resolution speed and position monitoring. An Aux. Interface without additional modules simplifies the control cabinet layout and reduces installation complexity. Speed commands are communicated via the native SERCOS – Interface Speed Command Value, allowing seamless integration into real-time automation networks.

With a compact footprint and the Series 3 control generation, the KDA 3.2-050-3-LQ0-U1 optimizes cabinet space and enhances serviceability. The combination of high stiffness, forced cooling, and advanced encoder support delivers precise spindle dynamics and peak efficiency. This spindle drive is perfectly suited for modern CNC machining centers and high-speed production equipment where reliability and precision are paramount.
