Mitsubishi now supplies Ethercat-ready servo drives for demanding automation applications
Mitsubishi Electric Automation Systems
Melservo MR-J3-A series of servo drives
Mitsubishi Electric’s Melservo MR-J3-A series of servo drives can now be supplied Ethercat ready, with a communications module that is designed to deliver increased speed and performance for demanding motion control and other automation applications.
Ethercat is an open, fully implemented industrial Ethernet technology that has been developed to reduce response times in critical applications, making it suitable for demanding multi-axis servo systems. It also ensures the tight synchronisation of multiple devices, enabling multi-dimensional motion profiles to be executed accurately.
The Melservo MR-J3-A servo drive offers precise, fast positioning, vibration-free motion and smooth operation, even at low speeds.
The servo drive’s auto-tuning function includes a built-in automatic filter that eliminates vibrations, while an auto-gain search function is said to make it easy to adjust the servo.
