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.
Also, the cooling fan operates regardless of the cooling fan control settings to protect the
internal circuit when the input voltage is 480 VAC or higher for 400 V products.
5.19 Input Power Frequency and Voltage Settings
Select the frequency for inverter input power. If the frequency changes from 60 Hz to
50 Hz, the frequencies set above 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 function item settings from 50 Hz to 60 Hz.
Set Inverter input power voltage. Low voltage fault trip level changes automatically to
the set voltage standard.
5.20 Parameter save
The parameters the user has changed through the compatible common area are not
saved in the inverter memory. They are used for saving the changed parameter into
the inverter memory after changing the compatible common area parameter. The
parameters cannot be saved if the inverter is operating.
