8. Maintenance
The change of the operating environment of the inverter, such as the influence of temperature, humidity, smoke,
etc., and aging of the internal components of the converter, may lead to various faults of the inverter. Therefore,
the inverter must be checked daily during storage and use, and regular maintenance should be carried out.
8-1. Routine maintenance
When the frequency converter is turned on normally, please confirm the following items:
(1) Whether the motor has abnormal sound and vibration.
(2) Whether the frequency converter and motor have abnormal heating.
(3) Whether the ambient temperature is too high.
(4) Whether the load ammeter is the same as usual.
(5) Check whether the cooling fan of frequency converter operates normally.
8-2. Regular maintenance
When the frequency converter is regularly maintained and inspected, it is necessary to cut off the power supply,
and the inspection can only be carried out after the monitor is not displayed and the power indicator of the main
circuit is off. The inspection contents are shown in the table below.
