Note 1: If the load applied to the inverter exceeds 150% of its rated load or the operation frequency is less than
0.1Hz, the inverter may trip (
ol1
or
oc1
to
oc3
) in a shorter time.
Note 2: The inverter is default setting so that, if the inverter becomes overloaded, it will automatically reduce the
carrier frequency to avoid an overload trip (
ol1
or
oc1
to
oc3
). A reduction in carrier frequency
causes an increase in noise from the motor, but this does not affect the performance of the inverter.
If you do not want the inverter to reduce the carrier frequency automatically, set the parameter
f316
=
0
.
Note 3: Overload detection level is variable by condition of output frequency and carrier frequency.
Note 4: Regarding to characteristic for

setting, refer to section 3.5.5).
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.
