KDA 3.2-050-3-L0D-W1

The Bosch Rexroth Indramat KDA 3.2-050-3-L0D-W1 from the KDA Spindle Drives series is engineered to deliver precise spindle control and robust performance in high-stiffness machining applications. Featuring a Rated Current of 50 A and a DC Bus Voltage of 300 V, this drive offers a broad continuous power range for demanding spindle operations. The primary function of this product is to manage and regulate spindle speed and torque in milling, drilling and turning centers, ensuring smooth acceleration and deceleration profiles with high positional accuracy.

Incorporating a Forced Cooled by Heatsink Blower design, the KDA 3.2-050-3-L0D-W1 maintains optimal operating temperatures even under heavy load conditions. The AC Supply Source for Heatsink Blower requires only 220 VAC, simplifying plant integration without the need for additional transformers. Command interfaces include a SERCOS - Interface Speed Command Value for real-time digital communication and a Position Command Value Digital 16-Bit Parallel aux interface for precise motion setpoints. The drive’s design iteration "2" and series classification "3" ensure compatibility with existing Indramat automation modules and significantly reduce commissioning time.

This spindle drive is engineered for seamless integration into modern CNC systems, offering high efficiency and reliability through a compact footprint. While no auxiliary encoder input is provided, the drive’s internal control algorithms compensate to maintain consistent torque delivery and speed regulation. The absence of auxiliary encoder input simplifies wiring and reduces potential failure points, enhancing overall system uptime. The device’s robust construction and forced cooling method extend service life in harsh industrial environments. By adopting the KDA 3.2-050-3-L0D-W1, manufacturers benefit from improved machining accuracy, reduced cycle times and lower maintenance costs, making it an ideal solution for precision metalworking and automated production lines.
