1: For normal motor, the lower the speed, the poorer the cooling effect. Based on this
reason, if output frequency is lower than 30Hz, inverter will reduce the motor overload
protection threshold to prevent normal motor from overheat.
2: As the cooling effect of variable frequency motor has nothing to do with running speed,
it is not required to adjust the motor overload protection threshold.

Figure 6.35 Motor overload protection curve.
The value can be determined by the following formula:
Motor overload protection current = (motor rated current / inverter rated current) * 100%
