The KDA 3.1-100-3-D0I-W1, Bosch Rexroth Indramat, KDA Spindle Drives provide a high-performance main spindle solution engineered for rigidity and precision. This module delivers a continuous Rated Current of 100 A and supports a DC Bus Voltage of 300 V, ensuring stable torque across a broad speed spectrum. Featuring an integrated digital 16-bit parallel speed command interface, it promises tight loop control and accurate positioning. Forced cooling via heatsink blower maintains thermal stability under sustained high-load conditions.
Built around a robust Design 1 housing, the drive draws power for its blower from an AC Supply Source for Heatsink Blower of 220 VAC. It incorporates an Aux. Interface providing Incremental Encoder Output for seamless machine feedback integration, while the Aux. Encoder Input is deliberately omitted to streamline signal routing. The drive’s advanced cooling system, labeled Forced Cooled by Heatsink Blower, evacuates heat effectively and extends component life. Series identification is reinforced by Product KDA and Series 3 markings, ensuring compatibility with established Bosch Rexroth Indramat accessory modules. The Speed Command Value capability of Digital 16-Bit Parallel supports microsecond-level response in multi-axis architectures.
Designed for straightforward integration into CNC spindles, milling centers, and high-speed drilling rigs, the KDA 3.1-100-3-D0I-W1 drive delivers reliable acceleration and repeatability. Its modular footprint and standardized connectors simplify retrofits and new builds, reducing installation time. The hardened design, combined with forced blower cooling and precise command inputs, ensures robust operation in demanding industrial environments.
