Setting Precautions
• If the motor capacity is small compared to the Inverter capacity or if the inverter is operated using the fac-
tory settings and the motor stalls, lower the set value of L3-02.
• If using the motor in the field weakening range, L3-02 will be automatically lowered to prevent stalling. It
will be reduced to a fixed value of 50 % of the inverter rated current.
• Set the parameters as a percentage taking the inverter rated current to be 100%.
