KDA 3.1-150-3-DYS-W1

The Bosch Rexroth Indramat KDA 3.1-150-3-DYS-W1 is a high-performance spindle drive from the KDA Spindle Drives series, designed to deliver precision and reliability in industrial automation. This drive supports a rated current of 150 A and can handle peak currents up to 300 A, ensuring rapid response to dynamic load changes. It operates on a DC bus voltage of 300 V and accepts a wide input voltage range of 3 × 208–480 V AC, making it adaptable to various power infrastructures. With a maximum ambient temperature rating of 45 °C, the unit maintains stable operation in warm industrial environments. The drive’s water-cooled (W1) design and panel mount configuration optimize thermal management and system integration.

Technical capabilities of the KDA 3.1-150-3-DYS-W1 encompass versatile control and feedback systems. The drive employs a SERCOS control interface and digital (DYS) feedback, enabling high-speed, deterministic data exchange with CNC controllers and supervisory systems. It offers current, speed, and position control modes, allowing engineers to fine-tune torque, maintain constant velocity, or achieve precise indexing as required. The Speed Command Value: Digital 16-Bit Parallel input provides high-resolution setpoint accuracy. Auxiliary encoder support is provided via aux. encoder input with auxiliary and synchronous inputs (AS 35 and Speed Command Value = A), expanding compatibility with advanced motion schemes. Designed for multi-axis applications, the drive supports up to 3 axes in a single cabinet, simplifying cabinet wiring and reducing footprint.

Operational features of the KDA 3.1-150-3-DYS-W1 emphasize durability and ease of maintenance. Its IP20 protection rating safeguards internal components against accidental contact and ingress of solids while ensuring adequate ventilation. The drive’s water-cooled (W1) heat exchanger rapidly dissipates thermal energy, maintaining optimal junction temperatures during continuous or peak-load operation. Rated for a maximum ambient temperature of 45 °C, it complies with stringent industrial temperature classes. A robust panel mount design with standard cutouts allows seamless retrofit into existing control cabinets. In addition, the drive’s product design 1 architecture aligns with industry norms for electromagnetic compatibility and safety.

Integration of the KDA 3.1-150-3-DYS-W1 into complex automation systems is straightforward, thanks to its support for a wide range of motors and network topologies. It is compatible with MAC, MDD, MHD, and similar synchronous/asynchronous motors, providing maximum flexibility in motor selection. The drive’s SERCOS interface ensures deterministic communication in multi-node networks, while its auxiliary inputs support advanced encoder configurations. Ideal applications include spindle control in machine tools, rotary indexing in assembly lines, and high-speed automation in packaging equipment. With its combination of high current capacity, precise feedback, and robust cooling, the KDA 3.1-150-3-DYS-W1 meets the demanding requirements of modern industrial environments.
