Chapter 5 Maintenance and Troubleshooting

5.1 Maintenance of the Servo Drive

5.1.1 Daily Maintenance
The influence of the ambient temperature, humidity, dust and vibration will cause the aging of the devices in the
servo drive, which may cause potential faults or reduce the service life of the servo drive. Therefore, it is necessary
to carry out routine and periodic maintenance.
Check the following items every day.
Inspection Item
Motor
Installation environment
Fan
Servo drive
The routine cleaning involves:
Keep the servo drive clean all the time.
•
Remove the dust, especially metal powder on the surface of the servo drive, to prevent the dust from entering
•
the servo drive.
Clear the oil stain on the cooling fan of the servo drive.
•
5.1.2 Periodic Inspection
Perform periodic inspection in places where daily inspection is difficult.
The periodic inspection involves:
Check and clean the air duct periodically.
•
Check whether the screws become loose.
•
Check whether the servo drive is corroded.
•
Check whether the wiring terminals have arc signs.
•
Carry out the main circuit insulation test.
•
Note
• Before measuring insulating resistance with megameter (500 VDC megameter recommended),
disconnect the main circuit from the AC drive.
• Do not use the insulating resistance meter to test the insulation of the control circuit. The high voltage
test need not be performed again because it has been completed before delivery.
Inspection Points
Check whether abnormal oscillation during the motor running.
Check whether noise exists during the motor running.
Check whether the installation environment changes.
Check whether the cooling fan of the servo drive works abnormally.
Check whether the servo drive is overheated.
