KDA 3.1-100-3-DPS-U1

The Bosch Rexroth Indramat KDA 3.1-100-3-DPS-U1 spindle drive from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers industrial-grade performance with high rigidity, precise positioning features, and a broad speed range under continuous power. Its robust architecture supports a Rated Current of 100 A and sustains a DC Bus Voltage of 300 V, ensuring stable torque delivery across demanding spindle applications. A Digital 16-Bit Parallel Speed Command Value interface enables fine-grained speed control, while the integrated heatsink blower provides efficient thermal management. This drive is designed for seamless integration into high-demand machining centers.

The KDA 3.1-100-3-DPS-U1 drive incorporates a Forced Cooled by Heatsink Blower scheme driven by an AC Supply Source for Heatsink Blower at 115 VAC, maintaining optimal junction temperatures under full load. Auxiliary connectivity includes an Aux. Encoder Input for spindle or secondary motor feedback and a bidirectional Aux. Interface via Serial Interface RS 232 C for parameterisation and diagnostics. The unit bears a compact Design rating of 1 within the Product family, classified under Series "3" for straightforward reference in multi-axis installations. All internal electronics are mounted on conformally coated boards, enhancing insulation resistance and protecting against airborne contaminants.

Engineers benefit from the drive’s plug-and-play compatibility with CNC motion controllers, reducing commissioning time and ensuring consistent repeatability in milling, drilling, and grinding operations. The combination of high overload capacity, comprehensive feedback options, and reliable heatsink blower cooling enhances system uptime and minimizes maintenance interventions. Ideal for precision spindle control, the KDA 3.1-100-3-DPS-U1 drive provides exceptional stability and long-term reliability in demanding manufacturing environments.
