User V/F curve.
)7+!"-&!!'&
The Energy Save parameter has three selections:
None, Manual and Auto.
This function is used to reduce the output voltage in
applications that do not require full torque and
current at steady speed. The inverter reduces its
output voltage for energy saving at steady speed.
Manual-If the manual energy save level is set at
20%, the output voltage will be decreased by 20%
when VFD runs at steady speed.
Auto- The VFD determines the energy saving level
automatically.
This function may cause over-current trip due to the
lack of output torque in a fluctuating load system.
When Energy Save is ON, it may take longer to
decelerate to stop.

This parameter display shows accumulated power
meter reading in Megawatt- Hours and Kilowatt-
Hours.
)77+$!&" "("'" '"E1
This parameter display shows in Celsius the actual
temperature of the VFD power module. The module
temperature of the VFD running at full speed with
ambient temperature less than 77°F should be less
than 60°C.
)70+ "" '"E1
This parameter display shows in Celsius the actual
motor temperature if thermistor sensor is installed
in motor winding and connected to VFD’s
terminals 5G and NT or ET. The motor overheat
protection can be set in parameters I/O-97 and I/O-
98.

When FG1-57 is set to Yes, FG1-58 to 5% of motor
FLA, SET-03 FLA to 10A and FG1-59 to 0.1sec.,
the VFD will trip on No Motor fault when output
current is less than 0.5A for 0.1sec
and VFD
frequency is above SET-13 . This parameter can
provide some degree of protection for VFD when
motor circuit is open during VFD operation.

The electronic motor overload protection [ETH]
provides motor protection based on inversed
thermal curve.
FG1-60 enables ETH protection mode.
FG1-61 sets the slope of the thermal curve as a
percentage of the motor FLA for 1min to trip VFD.
FG1-62 sets the service factor current (SFLA) as a
percentage of the motor FLA for continuous run.
