KDA 3.2-150-3-LQI-W1

The Bosch Rexroth Indramat KDA 3.2-150-3-LQI-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision and robustness in a single package. This main spindle drive offers a Rated Current of 150 A and a DC Bus Voltage of 300 V for demanding machining and milling applications. Built on a Design 2 platform and designated as Product KDA, Series 3, the unit features Forced Cooled by Heatsink Blower operation powered from a 220 VAC supply for thermal stability. A native SERCOS - Interface Speed Command Value and Incremental Encoder Output provide high-resolution feedback and seamless integration with modern CNC controls.

Engineered for rigidity and dynamic positioning, the drive supports extensive speed ranges under continuous power loads, ensuring smooth acceleration and deceleration profiles. The Aux. Encoder Input for 1V Sinusoidal Enc. enhances motion accuracy by delivering precise position signals directly to the control system. Thanks to its heatsink blower cooling strategy, temperature rise remains low even at peak output, reducing downtime linked to thermal derating. Built-in safety features and robust power conversion stages maintain consistent torque output across variable ambient conditions.

Integration is straightforward via standard SERCOS communication and encoder interfaces, simplifying commissioning and diagnostic routines. The compact footprint and modular construction minimize cabinet space requirements and facilitate field upgrades. With its combination of high current capacity, reliable forced cooling, and advanced feedback options, the KDA 3.2-150-3-LQI-W1 spindle drive is an ideal solution for high-precision manufacturing systems seeking dependable, long-term performance.
