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.

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.
