Setting Precautions
•
If the motor capacity is small compared to the Inverter capacity or if the motor is operated using the fac-
tory settings, resulting in the motor stalling, lower the value of L3-02.
•
If using the motor in the parameter output range, L3-02 will be automatically lowered to prevent stalling.
•
Set the parameters as a percentage taking the inverter rated current to be 100%.
