The MR-J3-xA-RJ158, offered as part of the Melservo MR-J3 family, is an AC servo drive designed to provide users with connectivity to Mitsubishi Electric high-performance servo amplifiers over EtherCAT communication. It connects with the MR-J3-T04 unit that is part of the required construct for the EtherCAT solution, and also houses the EtherCAT interface RJ45 connectors. With this solution, Mitsubishi Electric offers connectivity to EtherCAT master controllers over CANopen or CoE protocols along with the CiA402 drive profile application communication.

The line is designed for packaging, material handling, textile, machine tooling, printing and automotive applications, and leverages Mitsubishi Electric’s best-in-class servo amplifier performance. Enterprises that require the open EtherCAT network can now connect with the MR-J3 series’ machine analyzer and simulation, advanced gain search, vibration suppression control and auto tuning functions, among others

The EtherCAT amplifier has a capacity ranging from 100W to 22kW. These amplifiers will be able to drive the MR-J3 servomotors, which are equipped with built-in absolute high precision 18bit (262,155 pls/rev) standard. In addition to being compact and offering superb controllability, certain models also allow for up to 350 percent torque overload during acceleration and deceleration periods.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
