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%.
