„ Setting Precautions
• The motor may stall if the motor capacity is relatively small compared to capacity of the MxC, or if the
motor is operated with its defaults settings. Here, lower the value set to parameter L3-14.
• If using the motor in the constant torque range, L3-14 will be automatically lowered to prevent stalling.
L3-03 is the limit value to prevent the stall prevention level in the constant torque range from being
reduced more than necessary.
• Set L3-14 as a percent with the MxC rated voltage as 100%.
