0 : Disabled
1 : Fault when one phase is lost
If the drive loses one output phase, it will trigger LF [Output Phase Loss].
The output turns off and the motor coasts to stop.
2 : Fault when two phases are lost
If the drive loses more than one output phase, it will trigger LF [Output Phase Loss].
The output turns off and the motor coasts to stop.

(Hex.)
L8-09 Output Ground Fault
Detection
(04B5)
0 : Disable
The drive will not detect ground faults.
1 : Enabled
If there is high leakage current or a ground short circuit in one or two output phases, the drive will detect GF [Ground
Fault].
Note:
If the ground path impedance is low, the drive can detect oC [Overcurrent], SC [Out Short Circuit or IGBT Fault], or ov [DC Bus
Overvoltage] instead of GF.

L8-10 Heatsink Fan Operation
Selection
(04B6)
0 : During Run, w/ L8-11 Off-Delay
The drive turns on the fan when a Run command is active.
1 : Always On
The fan turns on when you supply power to the drive. When you release the Run command and the delay time set in
L8-11 [HeatsinkCoolingFan Off DelayTime] is expired, the fan stops. his setting extends the fan lifetime.
2 : On when Drive Temp Reaches L8-64
The fan turns on when the drive detects that the main circuit is overheating.

L8-12 Ambient Temperature
Setting
(04B8)
The drive automatically adjusts the drive rated current to the best value as specified by the set temperature. Set the
ambient temperature of the area where you install the drive to a value that is more than the drive rating.
