A VF motor (a motor for use with an inverter) can be used in lower frequency ranges than the general- purpose motor, but if that frequency is extremely low, the effects of cooling on the motor will deteriorate.

■Setting the motor electronic thermal protection level 1

If the capacity of the motor being used 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.

* If the indications are in percentages (%), then 100% equals the inverter's rated output current (A).				5
