■Setting of motor electronic thermal protection level 1 VJT (Same as H)
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 VJT so that it fits the motor's rated current.
