KDA 3.1-100-3-LQD-W1

The Bosch Rexroth Indramat KDA 3.1-100-3-LQD-W1 from the KDA Spindle Drives series delivers precision spindle control with a Rated Current of 100 A and a DC Bus Voltage of 300 V. This spindle drive operates on a Design 1 platform under the Product KDA family, featuring an AC Supply Source for Heatsink Blower of 220 VAC to maintain optimal operating temperature. Command integration is achieved via a Speed Command Value using the SERCOS interface alongside a Position Command Value Digital 16-Bit Parallel Aux. Interface. A dedicated Aux. Encoder Input for 1V Sinusoidal signals further enhances feedback accuracy and servo positioning.

Built for demanding spindle applications, the KDA 3.1-100-3-LQD-W1 offers continuous power delivery across an extensive speed range with high stiffness and dynamic response. The Cooling method is forced cooling by heatsink blower, ensuring stable thermal management under full 100 A load. The combination of a robust 300 V DC Bus Voltage and precision encoder support provides consistent torque output, minimizing vibration and maximizing machining accuracy. Modular design elements simplify maintenance and facilitate quick replacement of blower units and control modules without full system shutdown.

Integration into machine tool environments is streamlined by standardized mounting interfaces and electromagnetic compatibility in compliance with industrial controls. Technicians benefit from a unified drive topology within the KDA series, allowing parameter synchronization and fault diagnostics through the native SERCOS network. The result is a highly reliable spindle drive solution that elevates productivity in milling, turning, and high-speed drilling operations.
