If the motor capacity is small compared to the Drive capacity, or if the motor is operated using the factory

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 parameters as a percent taking the drive rated voltage to be 100%.
