KDA 2.1-150-3-L0D-W1

KDA 2.1-150-3-L0D-W1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive delivers high stiffness, precision positioning, and an extensive speed range for continuous power applications. Engineered for CNC machining centers and high-speed spindles, it integrates advanced control algorithms with rugged electronics to maintain torque stability under fluctuating loads. Its modular architecture streamlines installation in diverse machine platforms, while ensuring straightforward service access. The drive’s forced cooling mechanism guarantees thermal consistency even at peak operating currents, minimizing drift and prolonging component life.

The drive accepts an AC Supply Source for Heatsink Blower of bold>220 VAC, supporting robust thermal management via bold>Forced Cooled by Heatsink Blower methodology. A regulated bold>DC Bus Voltage of 300 V feeds the power stage, enabling a maximum bold>Rated Current of 150 A with stable performance across its operating envelope. Command inputs are handled through a bold>Position Command Value Digital 16-Bit Parallel bold>Aux. Interface, while speed references are delivered over a dedicated bold>SERCOS - Interface bold>Speed Command Value channel. The drive’s topology follows a bold>Design specification of 1, part of the bold>Product line KDA within bold>Series 2, and operates seamlessly without an bold>Aux. Encoder Input.

Integration into machine control systems is simplified by its standardized digital interfaces and plug-and-play architecture. High reliability is assured through forced-air heatsink blower cooling and robust power electronics designed for continuous 24/7 duty cycles. Ideal for milling, turning, and grinding applications, the KDA 2.1-150-3-L0D-W1 brings precision, efficiency, and uptime advantages to demanding spindle drive environments.
