KDA 3.2-150-3-AQS-U1

The Bosch Rexroth Indramat KDA 3.2-150-3-AQS-U1 from the KDA Spindle Drives series is a robust main spindle drive engineered for precision and durability. With a rated current of 150 A and a DC Bus Voltage of 300 V, this drive delivers consistent continuous power across a broad speed range. The drive’s product designation KDA and design code 2 reflect decades of innovation in spindle control technology. A native series 3 architecture ensures seamless integration into existing machining centers and automation lines.

Reliability is enhanced by a forced cooling strategy utilizing a dedicated heatsink blower powered by a standard 115 VAC supply source for heatsink blower. Feedback accuracy is maximized through the auxiliary encoder input supporting 1 V sinusoidal signals, while communication is handled via a serial interface RS 232 C. Speed reference is achieved through an analog ±10 V speed command input, providing proportional control and fine tuning for spindle acceleration and deceleration profiles.

Engineered for high stiffness and rapid positioning, this spindle drive excels in demanding milling, drilling, and turning applications. Its extensive speed range and continuous-duty rating make it ideal for modern CNC systems requiring precise torque delivery and minimal thermal drift. The KDA 3.2-150-3-AQS-U1 stands as a cornerstone solution where performance and reliability are paramount.
