Advanced Operation
This function detects changes in the main circuit's DC voltage which indicate a power supply phase
loss, large imbalance in the power supply voltage, or deterioration of the main circuit condenser.
Setting
0 Disabled.
1
Enabled. (Detects input power supply phase loss, 3-phase imbalance, or de
main circuit condenser.)
Parameter Display name p y
number
L8-07 Ph Loss Out Sel
Note This parameter cannot be changed during operation.
This function detects an Inverter output phase loss.
Setting
0 Disabled.
1 Enabled. (Detects an output phase loss at under 5% of the Inverter's rated output current.)
False phase loss detections may occur when the motor's capacity is small compared to the capacity of
the Inverter. In this case, disable the detection function by setting L8-07 to 0.
Parameter Display name p y
number
L8-10 Ground Fault Sel
Settings
Setting
0 Disabled. (No ground fault is protected.)
1 Enabled. (The ground fault is protected.)
The ground fault protective function can be enabled or disabled with the parameter.
The default setting does not normally need to be changed. Set the parameter to 0 if the output power
cable is as long as or longer than 100 m or the stray capacitance of the output cable is excessively high
and the ground fault protective function operates by mistake.

Spd
The inverter overload (OL2) characteristics can be set according to the application.
Set parameter L8-17 to 0 and parameter L8-10 to 1 if the motor has metal friction noise (or to increase
the carrier frequency).
