n140 018C Energy-sav-
ing control
coefficient K2
Sets the coefficient for the primary
level of energy-saving control.
Note The constant automatically
changes according to the
motor code in n158. Make
fine adjustments of the con-
tact if necessary after setting
the motor code in n158.

n141 018D Energy-sav-
ing voltage
lower limit at
60-Hz output
These parameters prevent the out-
put voltage of the Inverter from drop-
ping excessively so that the motor
will not stall or come to a stop at the
primary level of energy-saving con-
trol.

n142 018E Energy-sav-
ing voltage
lower limit at
6-Hz output
Sets the lower limit of output voltage
as a percentage at each frequency
based on the rated motor voltage as
100%.
Note Normally, the default settings
do not need to be changed.

n143 018F Power aver-
aging time
Sets the time required to calculate
the average of power used in ener-
gy-saving control.
Power averaging time (ms) = Set
value x 24 (ms)
