One’s place:
0: select MS frequency i, e.g. i=3, means the frequency forstage 3 is MS
frequency 3, see F8.00~F8.06.
1: the frequency is determined by F0.02

The overload protection is disabled. Be careful to use this function
because the inverter will not protect the motor in case of overload;
1
：
Common motor (with low speed compensation)
Since cooling conditions of common motor deteriorates at low speed,
the motor’s thermal protection threshold should also be adjusted. The
“Low Speed” here refers to the operating frequency lower than 30Hz.
2
：
Variable frequency motor (without low speed compensation)
The cooling effect of variable frequency motor is not affected by the
motor’s speed, so low speed compensation is not necessary.
In order to apply effective overload protection to different kinds of
motors, the Max output current of the inverter should be adjusted as
shown in Figure 6-75.
The efficient is calculated by the formula below:
Generally, the Max load current is the motor’s rated current.
