Deceleration
The Inverter decelerates normally and is not in energy-saving control.

Motor voltage
As shown in the graph, the voltage to
operate the motor most efficiently
varies with the motor load condition.
The Inverter in energy-saving control
adjusts the output voltage by using
the ideal calculated value so that the
actual output power will be minimum.
