The Bosch Rexroth Indramat KDA 3.2-100-3-DYD-U1 drive from the Bosch Rexroth Indramat KDA Spindle Drives series delivers precision motion control and high rigidity for demanding machining applications. Engineered as part of the KDA Spindle Drives family, this unit combines dynamic response with robust construction to maintain accuracy under heavy loads. The integrated design supports both continuous and intermittent spindle operation with seamless transition across the speed range. A compact form factor streamlines installation in confined machine tool electrical cabinets.
At its core, the drive features a DC Bus Voltage of 300 V and a Rated Current of 100 A to sustain high torque at low speeds. Heat management is handled by a Cooling Method of Forced air via heatsink blower, powered by a dedicated Heatsink Blower AC Supply of 115 VAC. Command signals are accepted through both a Position Command Interface and Speed Command Interface, each offering Digital 16-bit Parallel resolution for fine control of spindle positioning and velocity. The drive’s Design classification of 2 ensures electromagnetic compatibility and conformity to industrial standards, while the Aux. Encoder Input with auxiliary and synchronous inputs enhances feedback reliability.
Integration is simplified with a plug-and-play footprint that aligns with existing Bosch Rexroth Indramat control architectures, minimizing wiring complexity. The robust construction and forced-air cooling deliver reliable performance in high-duty-cycle environments, reducing thermal drift and extending service intervals. Ideal for CNC lathes, milling machines, and multi-axis machining centers, the KDA 3.2-100-3-DYD-U1 spindle drive ensures consistent throughput and precision over prolonged production runs.
