Maisart is an abbreviation for "Mitsubishi Electric's AI creates the State-of-the-ART in technology." Mitsubishi Electric is leveraging original AI technology to make devices smarter.

This function supports predictive maintenance by estimating frictions and vibrations of mechanical drive components such as ball screws and linear guides.

• Friction failure prediction with the friction estimation function
• Vibration failure prediction with the vibration estimation function

This function detects aging deterioration of belts in advance by the static friction failure prediction and the tension deterioration prediction with the belt tension estimation.

• Static friction failure prediction
• Belt tension deterioration prediction

With this function, the servo amplifier generates commands automatically, and executes to-and-fro positioning operation to estimate the amount of gear backlash. Gear failure is predicted based on the set nominal values for backlash.

• Backlash estimation function
• Gear failure prediction

• *1.The machine diagnosis (gears) does not work during normal operation.

This function estimates when a machine failure will occur based on the total travel distance of the servo motor and notifies when it is time for replacement if the rated service life of the mechanical drive components is set.

• Machine total travel distance failure prediction

This function displays the cumulative energization time and the number of inrush relay on/off times. The data can be used to check the service life of the parts as a rough guide.

• Cumulative energization time (Smoothing condenser/
  cooling fan life span)
• The number of inrush relay on/off times (Inrush relay life)
