Enhancing Machine Reliability with Preventive Maintenance and Advanced Troubleshooting Tools

In industrial automation, preventive maintenance is crucial for minimizing downtime and extending the lifespan of machinery. Mitsubishi Electric offers advanced diagnostic functions for mechanical drive components and servo amplifiers to ensure optimal machine performance.
 

Preventive Maintenance

Machine Diagnosis (Mechanical Drive Components): This function predicts machine failure based on the total travel distance of the servo motor. It notifies users when it is time for component replacement if the rated service life is set.

Servo Amplifier Life Diagnosis: Tracks cumulative energization time and inrush relay on/off times. This data serves as a rough guide for checking the service life of parts like smoothing capacitors and cooling fans.
 

Corrective Maintenance

Drive Recorder: Continuously monitors and records servo status transitions, such as conditions before and after alarms. This data helps analyze the cause of alarms using MR Configurator2, displaying monitor values, waveform history, system configuration, and servo parameters.

Connection/Communication Diagnosis

Disconnection Detection: Detects input and output open-phase issues in servo amplifiers, distinguishing these alarms from others to expedite system restoration. MR-J5D-G4 drive units support output open-phase detection.
 

Servo Motor Incorrect Wiring Detection: Multi-axis servo amplifiers (MR-J5W2-G/MR-J5W3-G) detect incorrect servo motor connections and provide protection by matching encoder capacity information with connected servo motors.
 

Encoder Communication Diagnosis: Checks the encoder communication circuit in the servo amplifier, useful for identifying errors like disconnected encoder cables.
 

By leveraging these advanced diagnostic functions, Mitsubishi Electric ensures robust predictive and preventive maintenance, enhancing machine reliability and reducing operational costs. Stay tuned to our blog for more insights into advanced automation solutions.
