z Electronic thermal detection of the inverter
In the 3G3MX2-V1 Series Inverter, the electric thermal function is separated for the inverter and for
the motor.
The electronic thermal function for the inverter is fixed to the rated current value of the inverter, inde-
pendent of the b012/b212 setting.
However, the characteristics of the inverter change because the rated current of the inverter varies
with the heavy and light load mode settings.
Below are the electronic thermal characteristics of the inverter.
Precautions for Correct Use
The inverter will trip if an overload is detected by either the inverter or motor electronic thermal
function.
The motor electronic thermal function detects E05. , and the inverter thermal function detects
E38. .
