2. Regularly inspect the ventilation hole of the control cabinet.
3. Change the installed place if there are heating objects, such as braking
resistors, in the surroundings.
4. Install/ add cooling fan or air conditioner to lower the temperature inside the
cabinet.
Check if there is any obstruction on
the heat sink or if the fan is
running.
Remove the obstruction or replace the cooling fan.
Insufficient ventilation space Increase ventilation space of the drive.
Check if the drive matches the
corresponded loading.
