The Beckhoff EL7201 Servomotor EtherCAT Terminal is a state-of-the-art component designed to deliver high servo performance in a remarkably compact form factor. This terminal is engineered to facilitate fast and dynamic positioning tasks, making it an ideal choice for applications requiring precision and efficiency.

With its integrated resolver interface, the EL7201 ensures accurate feedback and control of permanent magnet-excited three-phase synchronous motors. The terminal operates on a nominal voltage range from 8 to 50 V DC and can handle an output current of 2.8 ARMS, suitable for a wide array of industrial applications.

One of the standout features of the EL7201 is its advanced control technology, which includes field-oriented current and PI speed control. This technology underpins the terminal's ability to support rapid and highly dynamic positioning tasks, which are essential in modern automated processes.

The EL7201 also boasts robust monitoring capabilities, with safeguards against overvoltage, undervoltage, overcurrent, and terminal temperature. Additionally, motor load is monitored through the calculation of an I²T model, ensuring maximum operational reliability.

For seamless integration into PC-based control systems, the EL7201 utilises EtherCAT, a high-performance system communication protocol, along with CAN-over-EtherCAT (CoE) as the application layer. This combination provides an ideal interface for sophisticated control technology.

The terminal's use of the latest power semiconductors minimises power loss and enables energy feedback into the DC link when braking. For ease of diagnostics and status monitoring, the EL7201 is equipped with 16 LEDs that indicate status, warning, error messages, and any active limitations.

Overall, the Beckhoff EL7201 Servomotor EtherCAT Terminal is a compact, powerful, and reliable solution for automating and enhancing the precision of industrial processes.
