Frequency Reference @Loss
of Ref
Sets the frequency reference as a percentage to continue drive operation after it detects a frequency
reference loss. The value is a percentage of the frequency reference before the drive detected the loss.
80.0%
(0.0 - 100.0%)

Detects the frequency while the drive is operating. When the drive turns off its output, it will not detect frequency.
1 : Detection Always Enabled
◆
L5: Fault Restart
The Auto Restart function tries to keep machines operating when the drive detects a transient fault.
The drive can do a self-diagnostic check and continue the operation after a fault. If the cause of the fault goes away,
the drive does speed search and restarts. It will not stop and the drive will not record a fault history. Use
L5-02 [Fault
Contact at Restart Select]
to select the operation of fault relay signals during Auto Restart operation.
The Auto Restart function sets the drive to try to automatically restart the drive a set number of times in a set time. If
the number of Auto Restart tries is more than the set value during the set time, drive output shuts off and operation
stops. If this happens, remove the cause of the fault and manually restart the drive.
The drive can do Auto Restart when it detects these faults:
Note:
You can disable Auto Restart for faults if you must not restart the machine after the fault.
