KDA 3.2-100-3-AQS-U1

The Bosch Rexroth Indramat KDA 3.2-100-3-AQS-U1 unit from the KDA Spindle Drives series by Bosch Rexroth Indramat is a high-performance main spindle drive engineered for demanding CNC and precision machining applications. It delivers high stiffness mechanics and embedded positioning features that ensure rapid response to dynamic load changes and minimal settling times. The drive supports an extensive speed range with continuous power output, making it ideal for operations that require stable torque across varying RPMs. Designed for seamless plant integration, the KDA 3.2-100-3-AQS-U1 optimizes both machining efficiency and long-term accuracy.

The KDA 3.2-100-3-AQS-U1 delivers a nominal Rated Current of 100 A and a DC Bus Voltage of 300 V, ensuring robust torque reserve under heavy spindle loads. Speed setpoints are managed via an Analog +/- 10V Speed Command Value, while the unit’s forced cooling by heatsink blower system, powered by a 115 VAC AC Supply Source for Heatsink Blower, maintains optimal thermal conditions. Configuration and diagnostics are facilitated through a built-in Serial Interface RS 232 C, and the drive includes an Aux. Encoder Input for 1V sinusoidal encoders to support high-resolution feedback loops. Packaged in the compact Design 2 form factor of the KDA product family, it adheres to industrial robustness standards and simplifies replacement in retrofit scenarios.

Integration into multi-axis machining centers is streamlined via standardized interfaces and modular mounting, reducing installation time. The drive’s forced-cooled architecture and precise current regulation deliver reliability and minimal downtime in high-throughput environments. Continuous monitoring and diagnostic logging further minimize unplanned maintenance. Ideal for spindles in milling, drilling, and grinding machines, the KDA 3.2-100-3-AQS-U1 unlocks enhanced productivity and consistent surface finishes.
