Cooling Fan Control
This function turns the inverter’s heat-sink cooling fan on and off. It is used in situations where the
load stops and starts frequently, or noise free environment is required. The correct use of cooling
fan control can extend the cooling fan’s life.

Cooling Fan Control Detail Settings
Code Description
Ad.64 Fan Control
Settings Description
0 During Run Cooling fan runs when the operation (run) command is on.
The cooling fan stops when the operation command is off.
When the inverter heat sink temperature is higher than a
safe level, the cooling fan operates automatically
regardless of its operation status.
1 Always On Cooling fan runs constantly when power is supplied to the
inverter.
2 Temp
Control With power connected and the run operation command
on, if the setting is in Temp Control, the cooling fan will not
operate unless the temperature in the heat sink reaches
the set temperature.
Note
Despite setting Ad.64 to 0(During Run), if the heat sink temperature reaches an unsafe level, the
cooling fan may run as a protection function.
Input Power Frequency and Voltage Settings
Select the frequency for inverter input power. If the frequency changes from 60Hz to 50Hz, all other
frequency (or RPM) settings including the maximum frequency, base frequency etc., will be scaled
to 50Hz. Likewise, changing the input power frequency setting from 50Hz to 60Hz will scale all
related settings from 50Hz to 60Hz.
