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:
While the motor is running, make sure the frequency inverter sound is normal.
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 to see if the frequency inverter is overheating.
