•
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
Function
0
Disabled.
1
Enabled. (Detects input power supply phase loss, 3-phase imbalance, or de
t
erioration of the
main circuit condenser.)

This function detects an Inverter output phase loss.
Setting
Function
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.

•
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.

•
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).
