Beckhoff Automation (www.beckhoff.com) has introduced a compact servo technology solution with the release of the EL7201 servo terminal for the EtherCAT Terminal system. This 12 mm terminal offers a complete servo drive suitable for motors up to 200 W. Its integration into the EtherCAT I/O system effectively reduces costs and cabinet size requirements, while simplifying commissioning and cabling.
The new EL7201 servo terminal with resolver interfaces offers high servo performance in an exceptionally compact design. In addition, its integrated fast EtherCAT control technology, with PI speed control and field-oriented current, can support highly dynamic positioning tasks. Aside from the direct connection of a resolver and motor, a motor holding brake connection is also possible.
“The new EL7201 servo terminal is a true game-changer in the area of servo technology,” remarked Graham Harris, President, Beckhoff Automation.
“Small servo drives have been a popular technology for years and the EL7201 is a major evolution of this trend. Machine builders and manufacturers now have the option to control small servos with a 12 mm device.”
Permanent magnet synchronous motors, featuring a rated current of up to four A, can be connected to the new terminal as loads.
The new servo terminal provides maximum operational reliability, as it monitors various parameters, including undervoltage and overvoltage, overcurrent, motor load or terminal temperature.
Since it is fully integrated into Beckhoff’s TwinCAT automation software, the EL7201 servo terminal allows convenient parameterization. For third-party masters, parameterization occurs through the CAN over EtherCAT profile (CoE).
