6-7-2 Cooling Fan Operation Function (n35)
This parameter is used to operate the cooling fan of the Inverter while the
Inverter is turned on or only while the Inverter is in operation.
Set Values
• This parameter is available only if the Inverter incorporates a cooling fan.
• If the operation frequency of the Inverter is low, the life of the fan can be
prolonged by setting the parameter to 0.
6-7-3 Momentary Power Interruption Compensation (n47)
The parameter specifies the processing that will be performed when a
momentary power interruption occurs.
Set Values
Note 1. If the parameter is set to 1, an undervoltage warning will be detected and
the output of the Inverter will be shut off for 0.5 s when a momentary power
interruption occurs. The Inverter will restart after speed searching if power
is restored within 0.5 s. Undervoltage fault 1 will be detected if power failure
continues for more than 0.5 s.
2. If the parameter is set to 2, an undervoltage warning will be detected and
the output of the Inverter will be shut off when a momentary power
interruption occurs. The Inverter will then wait for power restoration. When
power is restored, the Inverter will restart after speed searching.
