L4-06: Frequency Reference at Reference Loss
n
Sets the frequency reference level at which the drive runs when L4-05 = 1 and a reference loss was detected. The value is
set as a percentage of the frequency reference when the loss was detected.
No.
L4-06 Frequency Reference at Reference Loss
L4-07: Speed Agreement Detection Selection
n
Determines when frequency detection is active using parameters L4-01 through L4-04.
No.
L4-07 Speed Agreement Detection Selection
Setting 0: Detection during run (no detection when drive output shut down)
Setting 1: Detection always enabled
u L5: Fault Restart
After a fault has occurred, this function attempts to automatically restart the motor and continue operation instead of
stopping.
The drive can be set up to 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
(Refer to b3: Speed Search on page 110
Note: 1. The wiring sequence should remove the Forward/Reverse command when a fault is triggered and output is shut off.
2. With the Forward/Reverse command removed, the drive can perform a self-diagnostic check and attempt to reset the fault
automatically.
The drive can attempt to restart itself following the faults listed below.

CF Control Fault
CFA nn CoF Current Offset Fault
CFA nn FU Fuse Blowout
CFA nn OC Overcurrent
CFA nn oH1 IGBT Overheating 1
CFA nn OV1 Overvoltage 1
CFA nn OV2 Overvoltage 2
GF Ground Fault
LF Output Open Phase
<1> When L2-01 is set to 1 or 2 (continue operation during momentary power loss ride-thru)
Use parameters L5-01 to L5-05 to set up automatic fault restart.
To output a signal during fault restart, set H2-01, H2-02, or H2-03 to 1E.
