KDA 3.1-150-3-L0D-W1, Bosch Rexroth Indramat, KDA Spindle Drives opens a new standard in main spindle control with robust digital positioning and high stiffness. This KDA 3.1-150-3-L0D-W1 drive provides seamless integration into advanced CNC systems, leveraging its modular KDA Spindle Drives architecture from Bosch Rexroth Indramat. Built for demanding machining centers, it balances precision and power to maintain tight tolerances under heavy loads. Its compact footprint and rugged construction enable straightforward retrofits and new installations alike.



The drive outputs a continuous **Rated Current** of **150 A** at a **DC Bus Voltage** of **300 V**, ensuring stable torque delivery across the entire speed range. Heat dissipation is managed via **Cooling** by a dedicated heatsink blower powered from **AC Supply Source for Heatsink Blower** at **220 VAC**, sustaining thermal performance even under peak loads. Motion commands are received over the high-speed **Speed Command Value** **SERCOS ‑ Interface**, while machine feedback loops can connect via the **Aux. Interface** offering a **Position Command Value Digital 16-Bit Parallel** link. The design (“**Design**: 1”) employs field-proven power electronics, and with no additional encoder needed—courtesy of **Aux. Encoder Input** marked **Without**—setup is simplified.



Engineers benefit from the KDA 3.1’s deterministic response and forced-air reliability, reducing downtime in high-volume production. Its compatibility with standard Rexroth automation platforms streamlines system integration and parameter cloning. Ideal for milling spindles, grinding applications, and precision tool machining, this drive delivers repeatable performance and long-term operational stability.
