Servo IO terminal for motor control
The EL7201 integrates a servo drive for motors up to 200 W into a 12mm I/O terminal housing for the EtherCAT terminal system.
Beckhoff 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).

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
