L8-09: Output Ground Fault Detection
No.
(Hex.)
Name Description
Default
(Range)
L8-09
(04B5)
Output Ground Fault
Detection
Sets the function to enable and disable ground fault protection.
1
(0, 1)
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
No.
(Hex.)
Name Description
Default
(Range)
L8-10
(04B6)
Heatsink Fan Operation
Selection
Sets operation of the heatsink cooling fan.
0
(0 - 1)
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.
■
L8-11: Heatsink Fan Off-Delay Time
No.
(Hex.)
Name Description
Default
(Range)
L8-11
(04B7)
Heatsink Fan Off-Delay
Time
Sets the length of time that the drive will wait before it stops the cooling fan after it cancels the
Run command when
L8-10 = 0 [Heatsink Fan Operation Selection = During Run, w/ L8-11 Off-
Delay] .
60 s
(0 - 300 s)

L8-12: Ambient Temperature Setting
No.
(Hex.)
Name Description
Default
(Range)
L8-12
(04B8)
Ambient Temperature
Setting
Sets the ambient temperature of the drive installation area.
40 °C
(-10 °C - +60 °C)
Note:
The setting range changes when the L8-35 [Installation Method Selection] value changes:
• 0 [IP20/UL Open Type] : -10 °C to +60 °C
•
1 [Side-by-Side Mounting] : -10 °C to +50 °C
• 2 [IP20/UL Type 1] : -10 °C to +50 °C
• 3 [Finless Installation] : -10 °C to +50 °C
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.
Refer to Derating Depending on Ambient Temperature on page 228 for information about derating as specified by
ambient temperature.
