Set Values
·Setn143tothetime 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.

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%.
