Note1 : At extremely low speeds of lower than 1 Hz, an overload trip (ol3) occurs in a short period of time to
protect the inverter.
Note2 : At over 150%, an overload trip (ol1 ) occurs in a short period of time to protect the inverter.
4) Electronic thermal memory f632
When the power is OFF, it is possible to reset or maintain the overload totaling level.
This parameter's settings are applied both to the motor's electronic thermal memory and the electronic
