KDA 2.1-050-3-A0D-W1

The Bosch Rexroth Indramat KDA 2.1-050-3-A0D-W1 from the KDA Spindle Drives series combines precision engineering with robust power handling. This drive supports a Rated Current of 50 A and a DC Bus Voltage of 300 V, ensuring stable energy delivery for high-performance spindles. Command inputs include a Speed Command Value Analog +/- 10V and an Aux. Interface Position Command Value Digital 16-Bit Parallel, while the design omits an encoder via Aux. Encoder Input Without for simplified system integration. Rated under Design 1 guidelines for the Product KDA family and classified as Series 2, this unit blends consistency with high technical flexibility.

The KDA 2.1-050-3-A0D-W1 drive excels in applications demanding tight position control, exceptional stiffness, and continuous power across an extensive speed range. Thermal management is secured by a Cooling Forced Cooled by Heatsink Blower system, which operates from an AC Supply Source for Heatsink Blower: 220 VAC to maintain optimal junction temperatures under peak load. Its high-resolution parallel interface supports 16-bit position commands, enabling sub-micron control loops and seamless communication with external PLCs or motion controllers. Moreover, the drive’s standardized footprint and connector layout facilitate straightforward replacement or system upgrades without mechanical redesign.

Engineered for demanding CNC mills, grinders, and multi-axis machining centers, this spindle drive delivers reliable torque and responsiveness. The absence of an auxiliary encoder input simplifies wiring harnesses and reduces potential failure points, while the integrated blower-cooled heatsink ensures sustained performance in high-duty cycles. With its combination of Bosch Rexroth Indramat quality, precise control features, and optimized thermal management, the KDA 2.1-050-3-A0D-W1 stands as an ideal solution for modern precision manufacturing environments.
