• Use this function to stabilize the motor in hunting.
• If the motor is hunting, check first whether the 1st/2nd Motor Capacity (H003/H203) and 1st/2nd
Motor Pole Number (H004/H204) settings match your motor and, if they do not, match them.
If the motor’s primary resistance is smaller than that of the standard motor, increase the value set in
the 1st/2nd/3rd Stabilization Parameter (H006/H206/H306) gradually. To drive a motor with a capacity
larger than the rated capacity of the inverter, reduce the set value.
• To suppress hunting, you can try the following methods as alternatives to this function.
