2) Whether or not vibration is generated during motor operation
3) Whether the inverter installation environment has changed
4) Whether the inverter cooling fan is working properly
5) Whether the inverter overheating
Daily cleaning:
1) Always keep the drive in a clean state.
2) Effectively remove the dust on the surface of the inverter to prevent dust into the
inverter inside. Especially metal dust.
3) Effectively remove the inverter cooling fan oil.
2.6.2 Regular Maintenance
Please check the place where you are difficult to check. Periodically check items:
1) Check the duct and clean it regularly
2) Check if the screws are loose
3) Check that the inverter is subject to corrosion
4) Check whether the terminal has a trailing mark
5) Main circuit insulation test
Reminder: When measuring the motor insulation resistance with a megger (please use a
DC 500V megger), disconnect the main circuit from the inverter. Do not use insulation
resistance meter to test the control circuit insulation. No need for high voltage test

2.6.3 Inverter replacement parts
Inverter parts are mainly cooling fan and filter electrolytic capacitors, the life and the
use of the environment and maintenance are closely related. The general life time is:
The user can determine the replacement age according to the run time.
1) Cooling fan
Possible cause of damage: bearing wear, leaf aging.
Criteria: fan blades, etc. whether there is cracks, whether the sound when the sound is
abnormal vibration.
2) Filter electrolytic capacitors
Possible causes of damage: Poor input power quality, higher ambient temperature,
frequent load transitions, and electrolyte aging. Criteria: whether the liquid leakage,
safety valve has been protruding, the determination of electrostatic capacitance,
insulation resistance determination.
2.6.4 Storage of the inverter
Users to buy the inverter, the temporary storage and long-term storage must pay attention
to the following:
1) Stored in the original packaging as far as possible into the company's packaging.
2) Prolonged storage will lead to the deterioration of electrolytic capacitors, must ensure
