KDA 3.1-100-3-DP0-U1

The Bosch Rexroth Indramat KDA 3.1-100-3-DP0-U1 spindle drive from the KDA Spindle Drives series offers high stiffness and precision positioning for demanding machining applications. With a rated current of 100 A and a DC bus voltage of 300 V, this drive delivers continuous power across a broad speed range. Equipped with a Digital 16-Bit Parallel Speed Command Value, it provides accurate spindle speed control for milling, turning, and grinding operations. The main function of this unit is to serve as a robust drive solution for machine tool spindles, ensuring consistent torque delivery and reliable performance under varying load conditions.

The technical architecture of the KDA 3.1-100-3-DP0-U1 drive is designed for seamless integration into CNC systems. It features an AC supply source for heatsink blower rated at 115 VAC, ensuring efficient operation of the forced cooling system. The drive supports an aux. encoder input for spindle or secondary motor feedback, enhancing motion control accuracy and enabling advanced diagnostic capabilities. While the aux. interface is supplied without additional modules, the drive’s compact Design 1 enclosure simplifies installation in control cabinets. The product classification is defined under Product: KDA and Series: 3, aligning with Bosch Rexroth Indramat’s modular drive platform.

Reliability and efficiency are further enhanced by forced cooling via a heatsink blower, which maintains optimal thermal conditions even under heavy loads. The KDA 3.1-100-3-DP0-U1 is compatible with standard spindle encoders and drive control units, ensuring straightforward system integration. Its robust construction contributes to long-term durability in high-vibration environments. By adhering strictly to Bosch Rexroth Indramat’s design guidelines, this drive maintains consistent performance and minimal downtime. In industrial settings, using this main spindle drive results in improved cycle times, precise motion control, and reduced maintenance costs, making it an ideal choice for modern machine tool applications.
