KDA 3.3-150-3-DQ0-W1

The Bosch Rexroth Indramat KDA 3.3-150-3-DQ0-W1 from the KDA Spindle Drives series is engineered to deliver precise spindle control with a rated current of 150 A and a DC bus voltage of 300 V. It features a high-resolution Digital 16-Bit Parallel Speed Command Value interface for fine speed adjustments and rapid response. Built on a rugged Design 3 platform, this unit belongs to the Product KDA family, ensuring consistency across machine tool installations. Its compact footprint and robust construction support demanding production environments without sacrificing performance.

Thermal management is handled by a Cooling Forced Cooled by Heatsink Blower system, maintaining stable temperatures during extended operation. The blower operates on an AC Supply Source for Heatsink Blower: 220 VAC, delivering continuous airflow to critical power stages. For motion feedback, an Aux. Encoder Input accepts 1 V sinusoidal encoders, while the Aux. Interface: Without design simplifies wiring and eliminates unnecessary circuitry. The drive is provided in Series 3, offering a standardized feature set that accelerates commissioning across multiple axes.

Integration of the KDA 3.3-150-3-DQ0-W1 is straightforward, with plug-and-play connections for power, control, and encoder signals. Its continuous power capability, combined with high stiffness and extensive speed range, makes it ideally suited for advanced spindle applications. Bosch Rexroth Indramat’s quality assurance ensures reliable operation and minimal downtime in precision machining centers.
