KDA 3.1-050-3-DPI-W1

The Bosch Rexroth Indramat KDA 3.1-050-3-DPI-W1 drive from the Bosch Rexroth Indramat KDA Spindle Drives series delivers high stiffness, precision positioning, and an extensive speed range optimized for main spindle applications. It supports continuous power operation with robust thermal management and dynamic response, making it ideal for demanding machining centers. Built on a proven digital architecture, the unit integrates seamlessly into existing automation environments. Its compact footprint and modular design simplify installation and maintenance.

Engineered for rigorous industrial use, the drive features a DC Bus Voltage of 300 V and a Rated Current of 50 A to handle peak torque demands. The heat sink blower operates on a dedicated AC Supply Source for Heatsink Blower of 220 VAC and implements Cooling via a Forced Cooled by Heatsink Blower arrangement, ensuring stable temperature control under full load. A Speed Command Value interface supports Digital 16-Bit Parallel signals for precise velocity regulation, while the Aux. Encoder Input provides feedback options With for Spindle or Second Motor Feedback. The Aux. Interface includes an Incremental Encoder Output channel for external monitoring, and the drive’s hardware follows Design specification 1 within the core Product family KDA and Series 3 framework for consistent system integration.

With hardened electronics and a rugged enclosure, this spindle drive assures long-term reliability even under continuous high-speed operation. Front-accessible connectors and standardized parameter cloning accelerate commissioning and reduce downtime. The KDA 3.1-050-3-DPI-W1 excels in CNC mills, turning centers, and high-precision automated machining lines where accurate control, rapid response, and maintenance simplicity are essential.
