The Beckhoff AX8640-0000-0000 is a power supply module engineered for high-performance automation systems that require reliable energy distribution to multi-axis servo drive setups. Designed as part of Beckhoff’s AX8000 series drive technology, this module delivers the stability, communication capabilities, and integration flexibility demanded by modern Industry 4.0 and motion control environments.

At its foundation, the AX8640-0000-0000 is designed to convert an incoming three-phase 200…480 V AC supply into a regulated DC link with a maximum of 848 V DC. With an impressive 40 A DC output current capacity, it is optimised for supplying demanding servo drive systems across multiple axes. This makes it particularly valuable in machinery and automation systems where high dynamic performance and synchronised motion are essential.

Integration into modern automation systems is streamlined with the inclusion of an EtherCAT system bus interface. EtherCAT, Beckhoff’s high-speed real-time fieldbus technology, provides fast and deterministic communication between the power supply module, servo drives, and higher-level controllers. This ensures precise coordination of multi-axis systems, enabling high throughput, accuracy, and responsiveness in advanced automation applications.

The AX8640 adheres to CiA402 drive profiles according to IEC 61800-7-201 (CoE), ensuring compliance with international standards. This compatibility allows seamless integration into a wide variety of applications and ensures interoperability with other CiA402-compliant devices. For engineers, this standardisation simplifies system design and enhances flexibility for future expansion or modification.

The operating temperature range is defined from 0…40 °C under nominal operation, with the ability to operate up to 55 °C under power reduction, as specified in documentation. This wide temperature tolerance highlights the robustness of the module, allowing it to perform reliably even in challenging industrial environments.

By forming part of Beckhoff’s AX8000 drive system, the AX8640-0000-0000 is not just a power supply but a core building block for scalable motion architectures. It provides the foundation for distributed DC link supplies, ensuring efficient power usage and optimised energy management across interconnected drive modules.

Applications for the AX8640 span industries such as packaging, robotics, machine tools, printing, and materials handling. In each case, it ensures stable and efficient power delivery while enabling precise synchronisation of motion tasks through EtherCAT-based communication.

In summary, the Beckhoff AX8640-0000-0000 Power Supply Module is a powerful, reliable, and standards-compliant solution for high-performance drive systems. With its robust AC-to-DC conversion, high output current, EtherCAT integration, and compliance with CiA402 profiles, it delivers the efficiency, precision, and scalability demanded by modern automation environments. Built to Beckhoff’s rigorous standards, it ensures long-term value and dependable operation in advanced industrial applications.
