ELM7222-0010 by Beckhoff

The ELM7222-0010 from Beckhoff is part of the ELM EtherCAT Terminals series and is engineered to support permanent magnet-excited three-phase synchronous motors. It features a direct motor connection with OCT and provides dual channels along with ample outputs to control two servomotors, two motor brakes, and a braking resistor. Notably, the terminal integrates advanced features such as a built-in absolute value interface and high-performance digital motor feedback, making it essential for fast and highly dynamic positioning tasks in industrial environments.

Meticulously designed, the terminal operates with a PWM clock frequency of 16 kHz and a current controller running at 32 kHz, ensuring precise modulation and responsiveness. It offers four digital input interfaces and two feedback inputs along with dual channels that enable simultaneous operation of various motor components. The product provides a stable supply voltage of 24 V DC via its power contacts while accepting an external DC link voltage ranging from 8 to 48 V DC. Additionally, it supports an output current with a maximum of 0.5 A and heavy load capability with 2 x 8 A output currents, supported by a peak current rating of 2 x 16 A for 1 s.

Complementing its robust technical architecture, the terminal is constructed with a durable metal housing that promotes rapid heat dissipation, ensuring reliable performance within an ambient temperature range of 0 to 55 degrees Celsius during operation and extended storage possibilities from -25 to 85 degrees Celsius. Designed for compatibility with modern industrial automation systems, the terminal's precise control combined with its efficient energy consumption, weighing approximately 0.39 kilograms, makes it an ideal solution for high-speed production lines and critical control applications. Its integration of both digital feedback technology and a reliable power interface underlines its benefit in enhancing operational efficiency and long-term durability across varied industrial settings.
