Beckhoff introduces EL7211 Servo Terminal

July 17, 2014 - Beckhoff introduces EL7211 Servo Terminal. This EtherCAT Terminal is available with integrated resolver interface or with the One Cable Technology (OCT) solution. When used in combination with Beckhoff servomotors, users take advantage of an extremely compact, efficient and inexpensive EtherCAT servo system. With the EL7211 servo terminal, the EtherCAT I/O system offers a complete compact servo drive with an output current of up to 4.5 ARMS  ̶ integrated into a space-saving, 24-mm wide terminal housing.

The EL7211 servomotor EtherCAT Terminal with integrated resolver interface offers drive power in a remarkably compact design for AM31xx and AM81xx series motors from Beckhoff. Designed with a 24-mm terminal housing, it delivers higher performance, with up to 4.5 ARMS at 50 V DC. This is an increase over the already proven and popular 12-mm wide EL7201 servomotor terminal with 2.8 ARMS.

As the EL7211-0010 servomotor terminal supports absolute encoders, it is ideal 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 speed control, is ideal 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 I2T model, 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.
