Cooling Fan Control
This function controls the operation of the inverter’s heat-sink cooling fan. It is used in
situations with frequent starting and stopping, or noise free environment is required. The
correct use of cooling fan control can extend the life of the cooling fan.
Cooling Fan Control Detail Settings
Cooling fan runs when the inverter is running. The
cooling fan stops when the inverter stops. If the
inverter heat sink temperature is higher than a set
value, the cooling fan will operate regardless of the
inverter’s operation status.
Cooling fan runs constantly when power is supplied to
the inverter.
With power connected and the start command on, the
cooling fan will not operate unless the temperature in
the heat sink reaches a set temperature.
Regardless of setting Ad.64 to 0 (During Run), if the heat sink temperature reaches a set
level, the cooling fan may run as a protection function. Also, for 480 V products, when the
input voltage is 480 VAC or higher, the cooling fan operates continuously to protect the
inverter regardless of the cooling fan control settings.
Input Power Frequency and Voltage Settings
Select the frequency of input power. When the frequency is set to 50 Hz, the frequencies set for 60
Hz (including the maximum frequency and base frequency) will change to 50 Hz. Likewise,
changing the input power frequency setting from 50 Hz to 60 Hz will change all related
settings from 50 Hz to 60 Hz.
Set Inverter input power voltage. Low voltage fault level changes automatically to the set voltage
standard.
