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.
Sets if the drive will do Auto Restart and the number of times the drive will try to do Auto Restart 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.
WARNING! Sudden Movement Hazard. Do not use the fault restart function in hoist or lifting applications. Failure to obey can
cause death or serious injury.
The drive can do Auto Restart when these faults occur:
Note:
You can disable Auto Restart for faults if you must not restart the machine after the fault.
