Note 1: At extremely low speeds of 1 Hz or less, an overload trip (ol3) can occur in a short time to protect the
inverter.
Note 2: At over 150% current , an overload trip (ol1) can occur in a short time to protect the inverter.
Note 3: Overload detection level is variable by condition of output frequency and carrier frequency.
Note 4: Regarding to characteristic for aul=2 setting, refer to section 5.6.5).
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
thermal memory for inverter protection.
