6-40
Set Values
• This parameter is used to set the electronic thermal protection constant of motor overload detection
OL1.
• The default setting does not need any changes in normal operation.
• To set the parameter according to the characteristics of the motor, confirm the thermal time constant
with the motor manufacturer and set the parameter with some margin. In other words, set the value a
little shorter than the thermal time constant.
• To detect motor overloading more quickly, reduce the set value, provided that it does not cause any
application problems.
6-10-3 Cooling Fan Operation Function (n039)
• 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
Value Description
0 The fan rotates only while the RUN command is input and for 1 minute after the Inverter
stops operating.
1 The fan rotates while the Inverter is turned ON.
• 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.
6-10-4 Momentary Power Interruption Compensation (n081)
• The parameter specifies the processing that will be performed when a momentary power interruption
occurs.

Value Description
0 Disabled. (An undervoltage fault will be detected when there is momentary power
interruption for 15 ms or more.)
1 The Inverter will continue operating if power is restored within 0.5 s. (See note 2.)
2 The Inverter will restart when power is restored. (See note 3.)
5 to 100 Power interruption recovery timer (Operation will continue after the set value times 0.1 s.)
Note 1. UV1 will be detected when a momentary power interruption occurs if n081 is set to 0. Opera-
tion cannot be continued until the UV1 error is cleared either by an error reset or by turning
OFF the Inverter for complete power discharge.
