Replacement of parts
The inverter consists of many electronic parts such as semiconductor devices.
The following parts may deteriorate with age because of their structures or physical characteristics, leading to
reduced performance or fault of the inverter. For preventive maintenance, the parts must be replaced periodically.
Use the life check function as a guidance of parts replacement.
* Replacement years for when the yearly average ambient temperature is 40°C (104°F)
(without corrosive gas, flammable gas, oil mist, dust and dirt etc)
(1) Cooling fan
The replacement interval of the cooling fan used for cooling the parts generating heat such as the main circuit
semiconductor is greatly affected by the ambient temperature. When unusual noise and/or vibration is noticed
during inspection, the cooling fan must be replaced immediately.
The FR-F720-00046, 00077, FR-F740-00023 to 00052 are not provided with a cooling fan.
