KDA 2.1-050-3-LPS-W1

The Bosch Rexroth Indramat KDA 2.1-050-3-LPS-W1 from the KDA Spindle Drives series delivers precision spindle control with 50 A rated current and a 300 V DC bus voltage. ThisKDA Main Spindle Drive (Product: KDA, Design: 1, Series: 2) offers extensive speed range and high stiffness, making it ideal for demanding CNC and milling applications. It supports closed-loop positioning features via a SERCOS interface speed command value, ensuring consistent motion accuracy. Manufactured to rigorous industrial standards, this unit integrates seamlessly with modern automation systems.

Performance is optimized through a forced cooling system provided by a dedicated heatsink blower, which operates on a separate AC supply source of 220 VAC. Feedback and synchronization are enabled by an auxiliary encoder input designed for spindle or secondary motor signals, delivering precise speed and position monitoring. Communication and diagnostics are facilitated through an RS 232 C serial interface, allowing quick parameterization and real-time status updates. The robust design maintains stable operation across a wide thermal range, while built-in protection circuitry guards against overcurrent and voltage spikes.

Installation and maintenance are simplified by the drive's compact footprint and modular connections. With the combination of a high-capacity DC bus, reliable cooling, and advanced SERCOS command support, the KDA 2.1-050-3-LPS-W1 represents a versatile solution for high-performance spindle drive applications. This spindle drive ensures repeatable accuracy and long-term durability in industrial machining centers, turning applications, and precision manufacturing environments.
