Set Values
•
Set n143 to the time required to calculate the average of power used in energy-saving control.
Power averaging time (ms) = Set value in n143 x 24 (ms)
•
Normally, the default setting does not need to be changed.
•
The Inverter averages the power for the set time for energy-saving control.
•
The value set in n143 is used for probe operation. The Inverter in probe operation changes the voltage
at intervals set in this parameter.
•
Increase the set value if the power fluctuates frequently and the Inverter cannot perform stable energy
control.

Set Values
•
When the output frequency is constant for a certain period while the Inverter is in effective energy-sav-
ing control, the Inverter is set to the primary level of energy-saving control by n140. Parameter n141
and parameter n142 prevent the output voltage of the Inverter from dropping excessively so that the
motor will not stall or stop at that time.
•
Set the lower limit of output voltage in percentage at each frequency based on the rated motor voltage
as 100%.
•
Normally, the default settings do not need to be changed. If the motor stalls or stops because the inter-
nal constants of the motor are special, increase the set values by approximately 5% to 10%.
