KDA 2.1-100-3-AQD-W1

The Bosch Rexroth Indramat KDA 2.1-100-3-AQD-W1 from the KDA Spindle Drives series is engineered for demanding spindle applications and offers robust performance with a Rated Current of 100 A and a DC Bus Voltage of 300 V. This Product KDA design (Design 1, Series 2) provides high stiffness and precision positioning across a wide speed range. The drive’s compact footprint accommodates a forced cooling solution, while its versatile command interfaces streamline integration. Native support for both analog and digital inputs makes the unit highly adaptable in modern CNC and automation environments.

Featuring a Speed Command Value: Analog +/- 10V input and a Position Command Value Digital 16-Bit Parallel interface, the KDA drive ensures accurate speed and position control. An integrated Aux. Encoder Input with 1V Sinusoidal Encoder feedback input further refines motor responsiveness and minimizes position error. Thermal management is maintained by a Forced Cooled by Heatsink Blower system powered via a dedicated AC Supply Source for Heatsink Blower: 220 VAC, ensuring consistent operation under heavy loads. Redundant safety monitoring and robust component selection extend service life in industrial environments.

With support for extensive continuous power output and dynamic load handling, the KDA 2.1-100-3-AQD-W1 excels in high-speed spindles, milling heads, and precision grinding machines. Its combination of 100 A rated current, 300 V DC bus, and versatile interfaces delivers reliable torque and speed control for cycle-intensive production. The result is a professional-grade spindle drive solution optimized for precision machining and high-throughput automation.
