Mitsubishi Electric recently introduced its new MELSERVO MR-J4 amplifier series with “one-touch tuning” function. Compared to the previous series, the MR-J4 series simplifies operation and commissioning once again while ensuring a high level of performance at the same time. The result: increased safety in the production process and productivity. Mitsubishi Electric has also been able to optimise the tried and tested “auto-tuning” function in the MR-J4 series once again. With the new “one-touch tuning” function, time-consuming system tuning between mechanical and electronic systems is minimised at the touch of a button: control parameters are automatically adjusted accordingly and the resonant frequencies of machinery and mechanical systems are identified and filtered. There is no need to balance individual applications. The result: a vibration-free, high-precision fast positioning process – with just one click.

“A servo system is a highly complex assembly with different PID controllers, resonance filters and parameters which have to be precisely adjusted to the relevant mechanical application”, explains Oliver Giertz, European Product Manager Servo/Motion at Mitsubishi Electric Europe B.V. “With the ‘one-touch tuning’ function, you can automatically set all the control parameters, including different filters for machine resonance and vibration suppression for example, at the touch of a button without any problems.” The improved tuning function reduces commissioning time to a minimum which ultimately leads to cost savings. Neither the technical knowledge of a control expert nor additional measurement devices are required. The MR-J4 series is suitable for a wide range of uses including high-precision pick-and-place applications with rapid positioning or for packaging machinery, positioning tables and handling systems for which vibration-free operation at a constant speed is what matters. Besides auto-tuning and vibration filters, the MR-J4 series has a “life diagnosis” function which checks the condition of the components installed throughout the lifecycle of the system and reports deviations. As a result, unscheduled downtime and idle time can be almost completely avoided. Mitsubishi Electric has gained many years of experience in the field of real time auto-tuning: since 1990, the company has implemented corresponding functions in its servo-amplifiers to which additional adaptive filters and vibration suppression methods have been added over the years.
