Common Faults & Maintenance

Typical Issues

• Axis communication loss: Oxidized connectors or backplane voltage instability

• Position drift: Weak encoder signals or component aging

• I/O timeout: ESD damage or overvoltage

Maintenance

• Use ESD protection when handling

• Clean gold‑plated connectors every 6 months

• Inspect solder joints annually

• Power off the system before removal/installation

Applications
