Torque (%)
When f615 = 1 (tripping), the inverter will trip if over-torque lasts for the period of time set with
f618 . In such a case, the over-torque signal remains ON.
Set to operate the fan only when the ambient temperature is high during operation. When the inverter
is on, the service life of the cooling fan is longer than if it is always running.
