Check whether there are foreign
matters blocking or attached to
the cooling fan, air inlets, or air
outlets.
6.1.2 Cooling fan
The service life of the cooling fan of the VFD is more than 25,000 hours. The actual service life
of the cooling fan is related to the use of the VFD and the temperature in the ambient
environment. You can view the running duration of the VFD through P07.14 (Accumulated
running time).
The increase of the bearing noise indicates a fan fault. If the VFD is applied in a key position,
replace the fan once the fan starts to generate unusual noise. You can purchase spare parts of
fans from INVT.
Read the safety precautions carefully and follow the instructions to
perform operations. Otherwise, physical injuries or damage to the device
may be caused.
1. Stop the device, disconnect the AC power supply, and wait for a time no shorter than the
waiting time designated on the VFD.
2. Pry the fan mounting plate up from the cabinet with a screwdriver, and lift the fan mounting
plate up. Loosen the fan cable from the cable clamp.
3. Disconnect the fan cable, and remove the fan mounting plate.
4. Install the mounting plate in the VFD in the reverse steps. Ensure that the air direction of
the fan is consistent with that of the VFD, as shown in the following figure.
