KDA 3.2-150-3-AYS-U1

The KDA 3.2-150-3-AYS-U1 drive from Bosch Rexroth Indramat, part of the KDA Spindle Drives, delivers precision spindle control with high rigidity and an extensive speed range. Engineered for continuous operation, it offers advanced positioning features and maintains stable torque across its full performance envelope. The robust mechanical design ensures minimal vibration and rapid response, making this drive ideal for demanding CNC and machine tool applications. Integrated parameters simplify commissioning and support consistent spindle behaviour under variable load conditions.

Incorporating a DC Bus Voltage of 300 V and a continuous Rated Current of 150 A, the unit sustains high-power spindle dynamics without derating. The drive’s Cooling system is Forced Cooled by Heatsink Blower, powered by an AC Supply Source for Heatsink Blower of 115 VAC to evacuate heat effectively. Speed regulation is achieved via an Analog +/- 10V Speed Command Value, while feedback is managed through an Aux. Encoder Input with auxiliary and synchronous inputs (AS 35 compatible). Communication and parameterization leverage the built-in Aux. Interface over Serial Interface RS 232 C, facilitating remote diagnostics and firmware updates. The modular Design (type 2) and compact packaging support integration into multi-axis spindle banks, and the dedicated Product architecture (KDA type) optimizes electromagnetic compatibility.

Engineers will appreciate seamless integration into existing motion control networks and the drive’s reliability under continuous-duty cycles. The KDA 3.2-150-3-AYS-U1 combines rugged construction with precise electronic control, reducing downtime and enhancing spindle throughput. Its proven performance in high-speed machining and precision drilling applications underscores its value in advanced manufacturing environments.
