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
