Courtesy: BeckhoffBeckhoff Automation  released the EL7201 servo terminal for the EtherCAT Terminal system. The EL7201 terminal integrates a complete servo drive for motors up to 200 W into a 12 mm I/O terminal housing. Integration into the EtherCAT I/O system considerably simplifies cabling and commissioning while reducing cabinet size requirements and costs.

The EL7201 servo terminal made its formal North American debut at the Pack Expo 2011 trade show. The EL7201 servo terminal with resolver interface features a compact design. The integrated fast EtherCAT control technology, with field-oriented current and PI speed control, supports highly dynamic positioning tasks. Apart from the direct connection of a motor and resolver, the connection of a motor holding brake is also possible.

Permanent magnet synchronous motors with a rated current of up to 4 A can be connected as loads. The monitoring of numerous parameters, such as overvoltage and undervoltage, overcurrent, terminal temperature or motor load, offers maximum operational reliability. Modern power semiconductors guarantee minimum power loss and enable feedback into the DC-Link when braking.

The servo terminal is fully integrated into TwinCAT automation software from Beckhoff, enabling parameterization. In the case of third-party masters, parameterization takes place via the CAN over EtherCAT profile (CoE).
