Check Points
8.4 Check Points
Daily inspections
•
Proper installation environment
•
Cooling system fault
•
Unusual vibration and noise
•
Unusual overheating and discoloration
Periodic Inspection
•
Screws and bolts may become loose due to vibration, temperature changes, etc.
•
Check that they are tightened securely and retighten as necessary.
•
Alien substances are clogged in the cooling system.
•
Clean it using the air.
•
Check the rotating condition of the cooling fan, the condition of capacitors and the
connections with the magnetic contactor.
•
Replace them if there are any abnormalities.
Replacement Parts
8.5 Replacement Parts
The drive consists of many electronic parts such as semiconductor devices. The following
parts may deteriorate with age because of their structures or physical characteristics,
leading to reduced performance or failure of the drive. For preventive maintenance, the
parts must be changed periodically. The parts replacement guidelines are indicated in the
following table. Lamps and other short-life parts must also be changed during periodic
inspection.

8 - Troubleshooting & Maintenance
Make sure to remove the input power while performing maintenance.
Make sure to perform maintenance after checking the DC link capacitor has discharged. The bus
capacitors in the drive main circuit can still be charged even after the power is turned off. Check
the voltage between terminal P or P1 and N using a tester before proceeding.
The RSi-GX series drive has ESD (Electrostatic Discharge) sensitive components. Take protective
measures against ESD before touching them for inspection or installation.
Do not change any inner parts and connectors. Never modify the drive.
