EJ7211-0010
The Beckhoff EJ7211-0010 is an advanced motion interface module from the EJ EtherCAT Plugins series by Beckhoff. This 1-channel plug-in interface is engineered for precise servo control in demanding automation applications. Key features include a direct motor connection with OCT (One Cable Technology) that combines power and feedback into a single cable, a broad supply voltage power range of 8–48 V DC, and a continuous output current (rms) capacity of 4.5 A. The module’s primary function is to drive permanent magnet-excited three-phase synchronous servomotors, delivering high-performance position and speed control in industrial environments.
In terms of technical specifications, the EJ7211-0010 integrates a Number Of Inputs configuration of 2 x end position, 1 x feedback channels, alongside Number Of Outputs of 1 x servomotor, 1 x motor brake. It offers a Peak Current (rms) of 9.0 A for 1 s, ensuring robust acceleration during transient loads. Control precision is maintained by a Rated Speed Controller Frequency of 16 kHz and a Pwm Clock Frequency of 16 kHz, while a Current Controller Frequency of 32 kHz provides fine resolution for current regulation. The module supports a Rotating Field Frequency range of 0 – 599 Hz and sources its electronics from a 24 V DC supply via a distribution board.
Designed for seamless system integration and reliable operation, the EJ7211-0010 delivers a 24 V DC output voltage for motor brake and a maximum Output Current Motor Brake of 0.5 A. Its compact dimensions (24 mm × 66 mm × 55 mm) and low weight (~50 g) enable installation in space-constrained cabinets. The module operates reliably from 0 °C to +55 °C and complies with EN 61000-6-2 for EMC immunity, ensuring durable performance in harsh industrial settings. Users benefit from simplified wiring through OCT, reduced cabinet complexity, and enhanced motion control accuracy, making this plugin indispensable for modern industrial automation.
