Set Values
·This function is used to stop accelerating the load if the output current exceeds the set
current value so that the Inverter will continue operating without stalling. The Inverter
accelerates the load while the output current is the same as or less than the set value.
·Set the parameter as percentage based on the rated Inverter current as 100%.
·The default setting does not need any changes in normal operation.
·Decrease the set value if the capacity of the motor is smaller than that of the Inverter or
the motor stalls with the default value.
The set value is normally 2 or 3 times higher than the rated current of the motor. Set this
current as percentage based on the rated inverter current as 100%.

Set Values
·This function will decrease the output frequency if the output current exceeds the set
current value by a minimum of approximately 100 ms so that the Inverter will continue
operating without stalling. The Inverter will increase the output frequency to return to
the set frequency reference level when the output current is less than the set value.
