KDA 3.1-100-3-AQI-U1

The Bosch Rexroth Indramat KDA 3.1-100-3-AQI-U1 from the KDA Spindle Drives series is a high-performance main spindle drive engineered for precision motion applications. This Product KDA unit features a Rated Current 100 A capability and a robust DC Bus Voltage 300 V, ensuring reliable power delivery across a broad operational envelope. Configured under Design 1 and identified as Series 3, it supports an Analog +/- 10V Speed Command Value for seamless integration with standard control systems. The drive’s incremental encoder interfaces are optimized for precise feedback and responsive spindle control.

Reliability and thermal management are central to the KDA 3.1-100-3-AQI-U1’s design, with a Cooling Forced Cooled by Heatsink Blower solution that maintains optimal junction temperatures under continuous load. The internal blower is powered by an AC Supply Source for Heatsink Blower 115 VAC to guarantee consistent cooling performance in demanding industrial environments. Feedback and positional accuracy are enhanced by the Aux. Encoder Input With Aux. Encoder Input for 1V Sinusoidal Enc. and an Aux. Interface Incremental Encoder Output for direct communication with auxiliary measurement systems. These interfaces permit high-resolution signal processing and contribute to minimized latency in closed-loop control.

Designed for spindle applications where high stiffness and dynamic response are required, this drive delivers continuous torque and speed regulation with minimal drift. Its extensive speed range and advanced positioning features make it suitable for milling spindles, rotary tables, and machining centers. The KDA 3.1-100-3-AQI-U1 offers a professional-grade solution for OEMs and system integrators seeking precise, reliable spindle performance in automated manufacturing processes.
