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 per-
form stable energy control.

Set Values
·
When the output frequency is constant for a certain period while the Inverter is in effec-
tive energy-saving control, the Inverter is set to the primary level of energy-saving con-
trol 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%.
