KDA 3.2-150-3-DPI-U1

The Bosch Rexroth Indramat KDA 3.2-150-3-DPI-U1 from the KDA Spindle Drives series delivers high-stiffness servo performance with precise spindle control and an extensive speed range. It features a Rated Current of 150 A and a DC Bus Voltage of 300 V that support continuous power delivery for demanding spindle applications. A Digital 16-Bit Parallel Speed Command Value ensures fine resolution in speed regulation, while Forced Cooled by Heatsink Blower thermal management maintains optimal operating temperatures. The drive’s internal AC Supply Source for Heatsink Blower of 115 VAC powers the cooling unit for consistent heat dissipation.

Advanced feedback and interface options enable seamless integration into modern automation systems. The KDA 3.2-150-3-DPI-U1 incorporates an Aux. Encoder Input with support for Spindle or Second Motor Feedback to monitor rotor position, paired with an Aux. Interface featuring Incremental Encoder Output for downstream motion controllers. Its Design 2 architecture and lightweight housing facilitate compact mounting, and the Product KDA platform unifies mechanical footprints across the family. The drive’s Series 3 electronics provide high switching frequencies and fast current loops, minimizing torque ripple and enhancing surface finish quality on machined parts.

Engineered for reliability, the spindle drive is optimized for CNC spindles, milling heads, and rotary indexing tables where precision and uptime are critical. High rigidity in the control algorithms reduces resonance, and the robust cooling blower extends maintenance intervals. The Bosch Rexroth Indramat KDA 3.2-150-3-DPI-U1 offers a balanced combination of power density and control finesse, making it ideal for high-performance machining centers and multi-axis processing equipment.
