KDA 2.1-050-3-AQD-U1

The Bosch Rexroth Indramat KDA 2.1-050-3-AQD-U1 drive from Bosch Rexroth Indramat in the KDA Spindle Drives series delivers high stiffness and precision positioning with an extensive speed range and continuous power output. Engineered as a main spindle drive, it is ideal for demanding CNC machining and milling applications that require reliable torque delivery. The unit’s rugged construction and advanced control electronics ensure stable operation under variable load conditions. Its compact footprint and modular interface simplify retrofitting into existing machining centers.

The KDA 2.1-050-3-AQD-U1 features a 300 V DC Bus Voltage paired with a Rated Current of 50 A, enabling sustained high-torque performance. Thermal regulation is provided by a Forced Cooled by Heatsink Blower system driven by a 115 VAC AC Supply Source for Heatsink Blower, which maintains optimal temperatures during peak operation. Control inputs include an Analog +/- 10V Speed Command Value and a Position Command Value Digital 16-Bit Parallel Aux. Interface, while precision feedback is achieved via an Aux. Encoder Input compatible with 1V Sinusoidal Encoder signals. Constructed to Design 1 standards and branded as Product KDA, this drive marries durability with industry-leading signal fidelity.

Integration is straightforward with Bosch Rexroth Indramat’s control platforms, enabling seamless coordination of spindle speed and position loops. The forced-cooled heatsink blower architecture and conformity to established design specifications enhance reliability and reduce downtime. Optimized for high-precision milling, drilling, and turning operations, the KDA 2.1-050-3-AQD-U1 elevates machining throughput and consistency.
