KDA 2.1-050-3-DPD-U1

The Bosch Rexroth Indramat KDA 2.1-050-3-DPD-U1 belongs to the robust KDA Spindle Drives family and combines precision engineering with high-performance spindle control. Engineered by Bosch Rexroth Indramat, this KDA Main Spindle Drive supports a Rated Current of 50 A and a DC Bus Voltage of 300 V for sustained torque delivery under demanding machining cycles. Designed as a Product KDA in Design 1 within Series 2, the module features a Speed Command Value of Digital 16-Bit Parallel control interface for microsecond-level response and deterministic positioning. Compact yet powerful, it integrates seamlessly into multi-axis CNC systems requiring both rigidity and high dynamic range.

High-speed feedback and auxiliary connectivity are achieved through the built-in Aux. Encoder Input for Spindle or Second Motor Feedback and a dedicated Aux. Interface with Digital 16-Bit Parallel position command value link. Active thermal management is ensured by the Cooling via Forced Cooled Heatsink Blower powered by an AC Supply Source for Heatsink Blower of 115 VAC, maintaining optimal junction temperatures during continuous operation. This spindle drive excels in vibration damping and stiffness, delivering consistent rotational accuracy over its extensive speed range. Advanced diagnostics and fault reporting capabilities further enhance machine uptime and simplify commissioning.

Compact in size yet industrially hardened, the KDA 2.1-050-3-DPD-U1 drive is ideal for milling spindles, turning centers, and drilling machines where precise speed regulation and rapid interpolation between axes are paramount. Maintenance is streamlined by accessible blower modules and standardized connector layouts, reducing mean time to repair. Ultimately, this drive represents a technically sophisticated solution for high-speed, high-stiffness spindle applications across aerospace, mold making, and precision component production.
