Ratingen, 11 April 2022 - Artificial intelligence offers important opportunities for optimising the maintenance of drive systems. Using large data sets from the manufacturing process, it is possible to recognise patterns which are then used to make precise predictions about the condition of the systems. As a result, maintenance work can be carried out at exactly the right time.

Artificial intelligence (AI) enables companies to make targeted maintenance decisions for their servo drives. It uses accurate forecasting models, real-time data and operating trends to schedule maintenance at exactly the right time - before failures occur, but only when it is necessary.

AI-based maintenance of servo drives

Since the release of its first digital servo amplifiers in 1987, Mitsubishi Electric has been collecting operational data on its products and their ancillary equipment. This extensive experience has now been incorporated into the development of the MELSERVO MR-J5 series.

The new servos use the company’s proprietary deep-learning AI Maisart® (Mitsubishi Electric's AI creates the State-of-the-ART in Technology) to schedule maintenance work at the best possible point in time. For this purpose, integrated sensors within the devices provide an accurate, real-time overview of the condition of internal components as well as mechanical devices linked to the drives, such as ball screws, belts and gears.

These capabilities are complemented by CC-Link IE TSN network technology which features gigabit bandwidth and Time-Sensitive Networking (TSN) functionalities. This allows large amounts of data for time-critical control tasks as well as less transient AI analytics information to be transmitted promptly and without delays.

Powerful servo technology

In addition to simplifying maintenance decisions, the MELSERVO MR-J5 servos are also designed to maximise the productivity of drive applications. For example, they comprise a portfolio of extremely powerful motors with a minimised footprint that can reach a maximum speed of 6,700 r/min.

In addition, the range includes compact amplifiers with a speed frequency response rate of 3.5 kHz and communication cycles of 31.25 μs. To conserve energy, the MR-J5D servo amplifier is also equipped with a regenerative unit.

By combining innovative maintenance, performance and efficiency, Mitsubishi Electric's latest servo systems optimise key production processes. To achieve this, equipment availability is enhanced as condition based monitoring and predictive maintenance opportunities are realised.
