Cooling Fan Control Detail Settings
Cooling fan runs when the power is supplied to the
inverter and the operation command is on. The cooling
fan stops when the power is supplied to the inverter
and the operation command is off. When the inverter
heat sink temperature is higher than its set value, the
cooling fan operates automatically regardless of its
operation status.
Cooling fan runs constantly if the power is supplied to
the inverter.
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.
Despite setting Ad.64 to 0(During Run), if the heat sink temperature reaches a set level by
current input harmonic wave or noise, the cooling fan may run as a protection function.
5.21 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 change to 50Hz. Likewise, changing the input power frequency setting from 50Hz
to 60Hz will change all related function item settings from 50Hz to 60Hz.
Set Inverter input power voltage at bA.19. Low voltage fault trip level changes
automatically to the set voltage standard.
