KDA 3.1-150-3-DPI-U1

The Bosch Rexroth Indramat KDA 3.1-150-3-DPI-U1 from the KDA Spindle Drives series is engineered as a high-performance spindle drive featuring a Rated Current of 150 A and a DC Bus Voltage of 300 V. This drive integrates a Speed Command Value in Digital 16-Bit Parallel format for precise velocity control and is Forced Cooled by Heatsink Blower to maintain optimal thermal stability. The unit’s AC Supply Source for Heatsink Blower is 115 VAC, ensuring reliable blower operation under demanding conditions. Robust design choices deliver exceptional stiffness and positioning accuracy across an extensive speed range.

Featuring an auxiliary feedback loop, the KDA 3.1-150-3-DPI-U1 supports an Aux. Encoder Input for spindle or second motor feedback and provides an Aux. Interface via Incremental Encoder Output for seamless integration with CNC controllers. The modular Design 1 package combines compact dimensions with high continuous power density, while the Product KDA platform ensures consistent mechanical and electrical footprints across the family. Classified under Series 3, this drive streamlines spare part management and reduces commissioning time. Intelligent electronic filtering and advanced control algorithms maximize torque response and minimize vibrations in high-precision machining operations.

Built for reliability, the KDA 3.1-150-3-DPI-U1 spindle drive excels in milling, turning, and grinding applications where rigidity and dynamic performance are critical. Its forced-air heatsink blower system maintains component temperatures within safe limits, extending service intervals and reducing maintenance efforts. With its blend of precise feedback interfaces, robust cooling, and industrial-grade power handling, this drive is an ideal choice for demanding CNC machine tools and automated manufacturing lines.
