Goodrive270 series VFD for fan and pump Maintenance
-289-
8.3 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 spares of fans from INVT.
