Description
Select the energy-saving control func-
tion.
0: Disabled
1: Enabled
Note This parameter is enabled in V/f
control mode only.
Set the coefficient for the primary
level of energy-saving control.
Note The constant automatically
changes according to the motor
code in n158. Make fine adjust-
ments of the contact if neces-
sary after setting the motor
code in n158.
These parameters prevent the output
voltage of the Inverter from dropping
excessively so that the motor will not
stall or come to a stop at the primary
level of energy-saving control.
Set the lower limit of output voltage in Set the lower limit of output voltage in
percentage at each frequency based
on the rated motor voltage as 100%.
Note Normally, the default settings
do not need to be changed.
Set the time required to calculate the
average of power used in energy-sav-
ing control.
Power averaging time (ms) = Set
value x 24 (ms)
Note Normally, the default setting
does not need to be changed.
Set the range of voltage control for
the secondary level of energy-saving
control.
Set the parameter in percentage
based on the rated motor voltage as
100%.
Note No probe operation is available
with the parameter set to 0.
Set the range of probe operation volt-
age in percentage based on the rated
motor voltage as 100%.
Note Normally, the default setting Note Normally, the default setting
does not need to be changed.
