KDA 3.1-100-3-L0I-W1

The Bosch Rexroth Indramat KDA 3.1-100-3-L0I-W1 drive is part of the renowned KDA Spindle Drives series designed for high-stiffness spindle applications. With a Rated Current of 100 A and a DC Bus Voltage of 300 V, this main spindle drive delivers continuous power across an extensive speed range. Its primary function is to provide precise positioning and reliable speed control for machining spindles, ensuring smooth operation even under variable load conditions.

In terms of technical specifications, the KDA 3.1-100-3-L0I-W1 features a dedicated AC Supply Source for Heatsink Blower rated at 220 VAC to maintain optimal thermal management. The drive implements a SERCOS - Interface for its Speed Command Value, offering deterministic, real-time communication for high-bandwidth control loops. Additionally, the drive’s Auxiliary Interface supports an Incremental Encoder Output for feedback, while the Aux. Encoder Input is omitted to streamline integration in legacy systems.

This spindle drive employs a robust Forced Cooling by Heatsink Blower configuration, enhancing durability and efficiency in demanding industrial environments. The design code 1 and series identifier 3 reflect its compliance with Bosch Rexroth Indramat’s engineering standards and modular architecture. With no auxiliary encoder input, the unit simplifies cabling requirements, reducing installation complexity. Overall, the KDA 3.1-100-3-L0I-W1 offers superior thermal stability and precision, making it an ideal solution for high-performance spindles in CNC machining, milling centers, and other industrial automation applications.
