. When the
actual current of motor reaches 140% of inverter rated current, inverter overload protection will
display after 1 minute.
Figure 9-12 Motor overload coefficient
When the output frequency is lower than 10Hz, the heat dissipation effect of common motor will
be worse. So when running frequency is lower than 10Hz, the threshold of motor overload value
will be reduced. Please refer to Figure 9-13 (F707=100%):
