Servo amplifier has EtherCAT connectivity

Mitsubishi’s 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.

Manufacturers 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 comes with a capacity ranging from 100W to 22kW, and can 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 quality controllability, certain models also allow for up to 350% torque overload during acceleration and deceleration periods.
