KDA 2.1-050-3-LPD-U1

The Bosch Rexroth Indramat KDA 2.1-050-3-LPD-U1 from the KDA Spindle Drives series exemplifies precision engineering with a rated current of 50 A and a DC Bus Voltage of 300 V to support continuous spindle operation. This main spindle drive features an extensive speed range and high torsional stiffness for demanding machining processes. Forced cooling via an integrated heatsink blower ensures stable thermal management under full load. Its robust construction and advanced positioning features make it ideal for high-speed applications in CNC machining centers.

Integration with peripheral systems is simplified through a dedicated AC Supply Source for Heatsink Blower at 115 VAC and a versatile Aux. Encoder Input for Spindle or Second Motor Feedback. Command and control are handled via a SERCOS interface Speed Command Value and a Position Command Value Digital 16-Bit Parallel Aux. Interface, delivering low-latency, deterministic performance. The drive’s cooling strategy of forced air ensures efficient heat dissipation, while its compact Design 1 form factor and Product KDA identity align with the modular Series 2 lineup for seamless cabinet integration.

Optimized for continuous-duty spindle tasks, the KDA 2.1-050-3-LPD-U1 drive balances high dynamic response with minimal footprint. Its combination of reliable feedback channels, precise digital interfacing, and active cooling delivers superior uptime and predictable torque delivery. Tailored for advanced manufacturing environments, this spindle drive enhances productivity and ensures consistent cycle times across diverse machining operations.
