Chapter 7 Maintenance and Troubleshooting
7.1 Routine Repair and Maintenance of the HV580L
7.1.1 Routine Maintenance
The influence of the ambient temperature, humidity, dust and vibration will cause the aging of the devices in
the AC drive, which may cause potential faults or reduce the service life of the AC drive. Therefore, it is
necessary to carry out routine and periodic maintenance.
Routine maintenance involves checking:
• Whether the motor sounds abnormally during running
• Whether the motor vibrates excessively during running
• Whether the installation environment of the AC drive changes.
• Whether the AC drive's cooling fan works normally
• Whether the AC drive overheats
Routine cleaning involves:
• Keep the AC drive clean all the time.
• Remove the dust, especially metal powder on the surface of the AC drive, to prevent the dust from entering
the AC drive.
• Clear the oil stain on the cooling fan of the AC drive.
7.1.2 Periodic Inspection
Perform periodic inspection in places where inspection is difficult.
Periodic inspection involves:
Check and clean the air duct periodically.
Check whether the screws become loose.
Check whether the AC drive is corroded.
Check whether the wiring terminals show signs of arcing;
Main circuit insulation test
Prompt: Before measuring the insulating resistance with mega meter (500 VDC mega meter recommended),
disconnect the main circuit from the AC drive. Do not use the insulating resistance meter to test the insulation
