[Using a VF motor (motor for use with inverter)]
Setting of electronic thermal protection characteristics selection
Setting value Overload protection
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
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
that it fits the motor's rated current.
* If the indications are in percentages (%), then 100% equals the inverter's rated output current (A).
