"When ￿￿￿￿=￿ (tripping), the inverter will trip if low current lasts for the period of time set with ￿￿￿￿.

After tripping, the low current signal remains ON.

￿, ￿, ￿: A check is made once at the first start of operation after the power is turned on or the inverter is reset.

Note: If the input voltage is rather high (480V as a guide) or the inverter is used to operate a high-speed motor, set

￿￿￿￿to ￿ or ￿. Any other setting may cause the motor to malfunction, because a high-speed motor has a very low impedance. If the inverter malfunctions for reasons of impedance even though ￿￿￿￿ is set to ￿ or ￿, then set ￿￿￿￿ to ￿ or ￿.
