L4-05: Frequency Reference Loss Detection Selection
The drive can detect a loss of an analog frequency reference from input A1, A2, or A3. Frequency reference loss is detected
when the frequency reference drops below 10% of the reference or below 5% of the maximum output frequency within 400
ms.

Setting 0: Stop. Drive stops when the frequency reference is lost.
Setting 1: Run. Drive continues operation according to the setting of L4-06.
The drive will continue operation at the percent of the previous frequency value set to parameter L4-06. When the external
frequency reference value is restored, the operation is continued with the frequency reference.

L4-06: Frequency Reference at Reference Loss
Sets the frequency reference level at which the drive runs when L4-05 = 1 and when detecting a reference loss. The value is
set as a percentage of the frequency reference before the loss was detected.

L5: Fault Restart
After a fault has occurred, Fault Restart attempts to automatically restart the motor and continue operation instead of stopping.
The drive can perform a self-diagnostic check and resume the operation after a fault has occurred. If the self-check is successful
and the cause of the fault has disappeared, the drive restarts by first performing Speed Search (
Note:
1.
The wiring sequence should remove the Forward/Reverse command when a fault is triggered and output is shut off.
