*1 Uv1 is the target for the auto restart process when L2-01 = 1 or 2 [Power Loss Ride Through Select = Enabled for L2-02 Time or Enabled
while CPU Power Active].
Note:
• The Fault Restart method is limited to the interval time that the drive will use L5-04 [Interval Method Restart Time].
• When L5-49 = 1 [Fault Retry Speed Search Select = Enabled], the drive will do a speed search when it resets and restarts after a fault.
• The drive will force the output frequency to zero during the auto-restart interval time.
• If you remove the Run (or HAND) command during the auto-restart interval time, the drive will immediately detect a fault and reset the
fault.
• The LOP [Loss of Prime] fault uses Y1-23 [Prime Loss Max Restart Time] for Auto Restart time. The other faults use L5-04 for Auto
Restart time.
• When you enable Thrust or Pre-Charge Modes, the drive will operate them correctly

The drive will only activate fault output when the drive cancels the Auto Restart function.
When you remove the Run command during the time set in L5-04 [Interval Method Restart Time], the drive will
cancel the Auto Restart function. At the same time, the drive will activate the fault output. Refer to
more information.
