Benefits of the Machine Analyzer Function

1. Identifying Mechanical Resonances Mechanical resonances can lead to excessive vibrations and affect the performance and lifespan of machinery. The machine analyzer function helps identify these resonances, allowing operators to take corrective actions.

Real-world example: In a printing press, identifying and addressing mechanical resonances can prevent vibrations that cause print misalignments and quality issues.

2. Optimizing Servo Control Parameters By analyzing the frequency characteristics of the mechanical system, the machine analyzer function provides insights into the optimal servo control parameters. This optimization enhances system performance and efficiency.

Real-world example: In a robotic arm used for precise assembly tasks, optimizing control parameters based on frequency analysis ensures smoother and more accurate movements.

3. Early Detection of Issues The machine analyzer function helps detect potential issues such as wear and tear, misalignments, and other mechanical problems before they lead to system failures. Early detection allows for timely maintenance and repairs, minimizing downtime.

Real-world example: In an automated conveyor system, early detection of bearing wear through frequency analysis can prevent unexpected breakdowns and production stoppages.

4. Enhancing System Reliability Regular use of the machine analyzer function contributes to the overall reliability of the automation system. By continuously monitoring and optimizing mechanical performance, operators can ensure consistent and reliable operation.

Real-world example: In a semiconductor manufacturing facility, maintaining system reliability through regular frequency analysis helps meet strict production standards and reduce defect rates.

Implementing the Machine Analyzer Function

1. Setting Up the Machine Analyzer Configure the machine analyzer function through the MR Configurator2 software. Set the parameters for frequency analysis based on the specific requirements of your mechanical system.

Tip: Choose a range of frequencies relevant to your application to ensure comprehensive analysis.

2. Conducting Frequency Analysis Use the machine analyzer function to conduct regular frequency analyses of your mechanical systems. Record and review the frequency response data to identify resonances and other issues.

Tip: Perform frequency analysis during different operational conditions to get a complete understanding of the system's behavior.

3. Optimizing and Troubleshooting Based on the analysis results, optimize servo control parameters and address any identified issues. Regularly use the machine analyzer function to monitor the effectiveness of these adjustments and make further refinements as needed.

Tip: Keep a log of frequency analysis results and the corresponding adjustments made to track improvements and maintain a history of system performance.
