Stall Prevention Function Chapter 6-3
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%.
