L8-09 Output Ground Fault
Detection
(04B5)
0 : Disabled
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, oC [Overcurrent], SC [Out Short Circuit or IGBT Fault], or ov [DC Bus Overvoltage] can stop the
motor.

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)
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 [External Heatsink]: -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 324
