Time Chart
The following figure shows the frequency characteristics when L3-01 is set to 1.

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 set value of L3-02.
• If using the motor in the constant output range, L3-02 will be automatically lowered to prevent stalling.
L3-03 is the limit value to prevent the stall prevention level in the constant output range from being
reduced more than necessary.
• Set the constants as a percent taking the Inverter rated voltage to be 100%.
