KDA 3.1-100-3-DQ0-U1

The Bosch Rexroth Indramat KDA 3.1-100-3-DQ0-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision motion control with a Rated Current of 100 A and a robust DC Bus Voltage of 300 V. This Product KDA with Design 1 chassis integrates a high-resolution Digital 16-Bit Parallel Speed Command Value interface and supports an Aux. Encoder Input for 1V Sinusoidal Enc. to achieve ultra-fine positioning. Thermal management is ensured by a Cooling system that is Forced Cooled by Heatsink Blower powered by a dedicated AC Supply Source for Heatsink Blower of 115 VAC. Connectivity is streamlined via an Aux. Interface Without, reducing wiring complexity and improving system reliability.

Engineered for demanding spindle applications, the KDA 3.1-100-3-DQ0-U1 features high stiffness and an extensive speed range under continuous power, making it ideal for milling, grinding, and drilling operations. The integrated heatsink blower maintains stable junction temperatures even under peak loads, while the DC bus architecture provides fast dynamic response and regenerative energy handling. The 16-bit parallel command input supports microsecond-level updates for rapid acceleration and deceleration profiles, and encoder feedback enables closed-loop torque and position control with minimal latency. With its compact footprint and standardized mounting, integration into both retrofit and new-build CNC machines is straightforward.

Combining rugged construction and advanced digital control, the KDA Main Spindle Drive excels in high-precision machining centers where reliability and accuracy are paramount. The synergy of a 300 V DC bus, 100 A current rating, and forced cooled thermal design ensures uninterrupted operation in continuous duty cycles. Its flexible encoder interface and simplified auxiliary connectivity make commissioning and maintenance efficient, positioning the KDA 3.1-100-3-DQ0-U1 as a cornerstone component for next-generation manufacturing systems.
