The KDA 3.1-100-3-DYD-U1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive combines high torsional stiffness with advanced positioning features and an extensive speed range. Designed for demanding CNC applications, it delivers continuous power output while maintaining precise speed control. The integrated digital 16-bit parallel Speed Command Interface ensures rapid and accurate response to motion profiles. A dedicated heatsink blower provides forced cooling to maintain optimal operating temperatures under heavy loads.
The unit handles a Rated Current of 100 A while maintaining a DC Bus Voltage of 300 V to support high torque at low speeds. Thermal management is achieved through Forced air via heatsink blower supplemented by a Heatsink Blower AC Supply of 115 VAC, ensuring consistent performance in extended duty cycles. It belongs to the Product Family KDA Series 3 and features a robust Design rating of 1, signifying reinforced industrial construction. Control connectivity includes an Auxiliary Encoder Input for auxiliary & synchronous signals and a dual-channel Auxiliary Interface delivering position commands via a 16-bit parallel bus, while the primary Speed Command Interface utilizes Digital, 16-bit parallel communication for tight control loops.
Seamless integration with CNC controllers and feedback systems simplifies commissioning and minimizes engineering effort. The forced-air cooling architecture and rugged industrial design deliver high reliability even in harsh manufacturing environments. Ideal for high-precision spindling applications, the drive ensures stable operation and maximum uptime.
