Operation
3-6-5 Selecting the Processing after Recovery from a
Momentary Interruption
• Use this parameter to select the processing to be performed when a momentary power interruption
occurs.
• When setting 1 or 2 is selected, an alarm is output when low voltage is detected in the main circuit,
and the alarm is automatically cancelled when the normal voltage resumes.
• If the power interruption is longer that the time for which Inverter operation can be performed, the
operation after recovery from the power interruption will be the same as the startup operation.
3-6-6 Selecting Operation Commands
• This parameter selects the input method for specifying Inverter starting, stopping, and direction of
rotation.
• There are two methods that can be selected for operation commands. Select the best method for
the application.
P08 Frequency reference lower limit Changes during
operation No
Setting range 0.1 to 120 (Hz) Setting unit 0.1 Hz (See note.) Default setting 0.0
P09 Momentary power interruption restart selection Changes during
operation No
Setting range 0 to 2 Default setting 0
Set value Description
0 (
0
) Inverter stops operating. (If the interruption lasts for 15 ms or longer, main circuit low voltage
will be detected and an error will occur.)
1 (
1
) Inverter continues operating if power interruption is 0.5 s or less. (If a power interruption
occurs when
1
is set for 0.5 s, the main circuit low voltage is detected and outputs are
stopped while waiting for power to be restored. If power is restored within 0.5 s, operation
resumes.)
2 (
2
) Inverter always continues operating. (If a power interruption occurs when
2
is set, outputs are
stopped while waiting for power to be restored. When power is restored, outputs are
resumed.)
