F8.14
V/F slip compensation
Setting range:0.0-200.0%
Factory set:0.0%
It makes inverter output frequency self adjust within a setting range according motor load change to compensate slip
frequency to make motor keep constant speed. It effectively relieves the impact of load change to motor speed.
If compensation setting is too big, it maybe causes motor speed over settings.

F8.16
Lowest frequency limit of
energy save running
Setting range: 0.0-500.0%
Factory set: 25.0%
F8.17
Energy save voltage
down time
Setting range: 0.01-50.00s
Factory set: 10.00s
F8.18
Energy save voltage
lowest limit
Setting range: 20.0-100.0%
Factory set: 50.0%
Auto energy save selection:
0: no auto energy save
1: auto energy save
Lower frequency limit of energy save running:
While output frequency is lower than this value, auto energy save
function will close. 100% is corresponding to motor rated frequency.
Energy save voltage down time:
It is the time output voltage from rated voltage to 0V while meet auto energy save
conditions.
Energy save voltage lowest limit:
Set lowest limitation of voltage while energy save running. 100% is corresponding
to motor rated frequency.

is valid under V/F with PG mode. It changes the speed responde features by setting proportion gain P
and integral time I of the speed adjuster.
