Mitsubishi MELSERVO MR-J5 servo drive25 February 2021

Mitsubishi Electric has launched the MELSERVO MR-J5 series of TSN-compatible servo drives that integrate a suite of safety functions as standard.

The system promises a frequency response of 3.5kHz and a communication cycle time of 31.25µs. Further, with the associated MELSEC motion module, users can synchronise up to 256 axes per module. The total system can support three motion modules allowing systems of up to 768 axes to be controlled.

A key enabler for improved performance across multi-axis servo systems is said to be the integration of CC-Link IE TSN (time sensitive network) technology with 1Gbps transmission speeds. Other network protocols such as EtherCAT are also offered as standard.

Predictive maintenance functions have also been embedded, helping to reduce unplanned machine downtime and drive-up asset availability, so saving both time and money. These functions are powered by Mitsubishi Electric’s Maisart AI technology, allowing this new servo drive series to detect mechanical component deterioration on the machine long before maintenance is required.

The MELSERVO MR-J5 series enables users to save time and money in other areas too. Machine wiring has been simplified with a new single cable – for encoder, power and electromagnetic brake – with a new one-touch lock connector which eliminates the need for tightening screws. The 26-bit absolute encoder offers 67 million pulses per revolution.
