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 out-
put current is less than the set value.
• The Inverter accelerates or decelerates the output frequency according to the preset acceleration or
deceleration time set in n116 (stall prevention acceleration/deceleration time setting).
• 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 in
percentage based on the rated Inverter current as 100%.
