KDA 3.1-100-3-AP0-U1

The KDA 3.1-100-3-AP0-U1, Bosch Rexroth Indramat, KDA Spindle Drives is a high-performance spindle drive optimized for demanding CNC and machining center applications. This module delivers a continuous Rated Current of 100 A and operates on a DC Bus Voltage of 300 V, ensuring consistent torque and high dynamic response. The integrated electronics and power stage are configured in a compact Design 1 housing, facilitating straightforward integration into existing drive cabinets. Built for precision, the drive offers advanced positioning features and an extensive speed range, making it ideal for main spindle control and high-stiffness tooling operations.

The device employs a Cooling system that is Forced Cooled by Heatsink Blower powered from an AC Supply Source for Heatsink Blower of 115 VAC, maintaining optimal thermal performance under heavy loads. Speed regulation accepts an analog Speed Command Value of +/- 10 V, while the Aux. Encoder Input is provided With for Spindle or Second Motor Feedback to support multi-axis synchronization and redundant position monitoring. An Aux. Interface is intentionally omitted to streamline signal routing and reduce complexity. The drive’s core product family is identified as Product KDA Series 3, ensuring compatibility with legacy Indramat controllers and facilitating plug-and-play upgrades.

Engineered for reliability, the KDA 3.1-100-3-AP0-U1 spindle drive features rugged power electronics and a robust blower-cooled heatsink that extends service intervals. Seamless integration with Bosch Rexroth Indramat control systems simplifies commissioning and diagnostic workflows, while the precise analog speed interface supports fine-tuned spindle acceleration/deceleration profiles. This drive delivers proven performance for high-precision milling, drilling, and turning centers where uptime, stiffness, and process stability are paramount.
