VF motors (motors designed for use with inverters) can be used in frequency ranges lower than those for
standard motors, but their cooling efficiency decreases at frequencies below 6Hz.
Setting of motor electronic thermal protection level 1 thr (Same as f173)
If the capacity of the motor is smaller than the capacity of the inverter, or the rated current of the motor is smaller
than the rated current of the inverter, adjust the electronic thermal protection level 1  so that it fits the
motor's rated current.
