KDA 3.1-100-3-DPI-W1

The KDA 3.1-100-3-DPI-W1, Bosch Rexroth Indramat, KDA Spindle Drives module delivers precise motion control for main spindle applications. Featuring inherent high stiffness and an extensive speed range, it supports continuous power across both low and high RPM environments. With a robust Design 1 chassis and compact footprint, it integrates seamlessly into CNC machining centers and milling spindles while simplifying installation and service access. The drive’s modular architecture supports both spindle and second motor feedback for versatile system configurations.

At its core, the Product KDA drive accepts a DC Bus Voltage of 300 V to deliver a continuous Rated Current of 100 A, achieving high output torque. Thermal management is handled by a Cooling system that uses a AC Supply Source for Heatsink Blower of 220 VAC, ensuring stable operation under full load and prolonging internal component lifespan. Motion commands are processed via a Speed Command Value interface with Digital 16-Bit Parallel precision, while the Aux. Interface provides an Incremental Encoder Output. An Aux. Encoder Input with support for spindle or secondary motor feedback expands diagnostic accuracy and synchronization capabilities.

Engineers benefit from the drive’s plug-and-play topology and standardized mounting flanges, which accelerate integration into existing control racks. Robust forced-cooling and precision encoder interfaces guarantee reliable performance in demanding spindle applications, from high-speed milling to precision grinding. With its combination of power density, flexibility, and proven Indramat technology, the KDA 3.1-100-3-DPI-W1 excels in high-precision machining environments.
