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%.
