5 Basic Settings
Electronic Thermal Characteristics
The electronic thermal function enables you to change the overload detection characteristics by setting
the 1st/2nd/3rd Electronic Thermal Characteristics Selection (b013/b213/b313) according to the motor
in use.
This section first describes the basic electronic thermal characteristics and then provides the details of
individual detection characteristics.
 Basic Characteristics
The electronic thermal characteristics differ between the heavy load mode and the light load mode.
In addition, because the electronic thermal characteristics are different at 75 kW or higher, this
inverter has four basic characteristics as follows.
