The frequency inverter's components age and have poor heat dissipation due to temperature, humidity, dust, and vibration; this could cause failure or limit the device's service life.
As a result, the frequency inverter needs regular, everyday maintenance.
Things to look over every day:
Check to see if the motor is producing a consistent sound while it is running.
Check to see whether the motor vibrates when it's running.
Check to see if the installation environment for the frequency inverter has changed.
Check to see if the cooling fan on the frequency inverter is running correctly and if the cooling air duct is clear.
Check the frequency inverter for overheating.
Make sure that the frequency inverter is always kept clean.
