This advanced EtherCATterminal offers impressive drive power in a remarkably compact design for the company’s AM31xx and AM81xx series motors. When used in combination with Beckhoff servomotors, users are able to take advantage of an extremely compact, efficient, and inexpensive EtherCAT servosystem. Designed with a 24-mm terminal housing, it delivers higher performance, with up to 4.5 ARMSat 50 V DC, than the popular 12-mm 12-mm wide EL7201 servomotor terminal with 2.8 ARMS.
As the EL7211-0010 servomotor terminal supports absolute encoders, it is suitable for the AM81xx servomotor series with One Cable Technology (OCT). OCT combines power and feedback signals into one standard motor cable and significantly reduces material and commissioning costs. The integrated electronic identification plate of the servomotors can be read in automatically by the EL7211-0010 EtherCAT Terminal which simplifies motor commissioning.
The fast control technology of the EL7211 servomotor terminal, which is achieved through field-oriented current and PI speedcontrol, is iuseful for fast and highly-dynamic positioning tasks. The monitoring of numerous parameters – e.g., overvoltage and undervoltage, overcurrent, terminal temperature, or motor load via the calculation of an I2Tmodel – offers maximum operational reliability. EtherCAT, as a high-performance communication system, and CAN over EtherCAT (CoE) as the application layer, serve as the optimum interface with PC-based control technology.
