- 1
Measure input voltage at the servo drive's main power terminals (L1, L2, L3) and control power terminals (24VDC) against specified nominal values.
- 2
Inspect all power, motor, encoder feedback, and control signal cables connected to the servo drive for physical damage, loose connections, and proper shielding/grounding.
- 3
Verify the integrity of the machine's grounding system, especially for the servo drive and motor, ensuring low impedance connections.
- 4
Check communication status between the Omron NJ/NX controller and the servo drive, and verify network settings if applicable (e.g., EtherCAT).
- 5
Verify servo drive parameters and configuration settings against the latest documented machine backup or manufacturer specifications for any discrepancies.
