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.

Set Values
•
The motor code is used for automatically setting the energy-saving constant in n140.
•
By setting the motor code, the value in n140 (energy-saving control coefficient K2) will change auto-
matically. To adjust energy-saving control coefficient K2, set the motor code in advance.
•
Select the motor code from the following table based on the power supply voltage of the Inverter and
the capacity of the motor.
