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.

Enhancing Machine Reliability by Predictive Maintenance with Mitsubishi Electric’s Maisart AI Technology

Mitsubishi and Corey Foster, Valin

In the rapidly evolving world of industrial automation, predictive maintenance is key to minimizing downtime and maximizing efficiency. Mitsubishi Electric’s cutting-edge AI technology, Maisart, integrated with their servo amplifiers, provides a robust solution for predictive maintenance, helping detect early signs of machine failure.

 
 

Ball Screws Diagnosis

Mitsubishi Electric introduces a ball screw machine diagnosis function that monitors friction and vibration to predict potential failures. By employing statistical algorithms, the system sets automatic failure warning limits. This proactive approach allows users to prepare necessary parts before a failure occurs, significantly reducing Total Cost of Ownership (TCO). Dynamic friction states of the ball screws are sent to the host management PC via CC-Link IE TSN, ensuring seamless and efficient maintenance planning.

Function:

  • Monitors friction and vibration to predict failure.

Process: 

  • A failure warning limit is automatically generated based on statistical algorithms.
  • An alarm is activated upon signs of failure, enabling preparation before failure.

Benefit: 

  • Allows you to prepare necessary parts before failure.
  • Reduces Total Cost of Ownership (TCO).
  • Notifications via CC-Link IE TSN.

Addressing Backlash with Mitsubishi Electric’s MRJ 5 Servo Amplifiers

Mitsubishi and Corey Foster, Valin

Understanding Backlash

In mechanical systems, backlash is the clearance or lost motion between parts, often due to manufacturing imperfections. This gap causes positioning errors, which can degrade machine performance.

Traditional Mitigation Methods

  • Load-Side Encoder: Provides real-time feedback, compensating for backlash. However, it increases machine cost and complexity.
  • Built-In Backlash Compensation: Allows input of backlash amount, offsetting motor motion accordingly. Accurate measurement requires special tools.


Mitsubishi Electric’s Innovative Solution

Our MRJ 5 servo amplifiers feature a built-in backlash estimation function, providing a quick and easy way to estimate and compensate for backlash without expensive tools.

Steps to Use the Backlash Estimation Function:

  • Power and Connect: Power on the amplifier and connect to your PC via USB.
  • Open MR Configurator 2: Switch to online mode.
  • Diagnosis Tab: Select Gear Failure Diagnosis to open the estimation function.
  • Set Parameters: Adjust settings to fit your application, write to the drive, and cycle power.
  • Start Process: Click Start. The drive moves and estimates backlash within two minutes.


Conclusion:

Mitsubishi Electric’s MRJ 5 servo amplifiers simplify backlash estimation, enhancing machine performance efficiently and cost-effectively. This innovative solution eliminates the need for complex, costly equipment, ensuring precise machine operation.
