• Use the torque boost function to raise the output torque if it is not sufficient at low speeds.
• This inverter provides two torque boost options: Manual torque boost for manual torque adjustment
and Automatic torque boost for automatic torque adjustment.
• To use the automatic torque boost function effectively, be sure to set the 1st/2nd Motor Capacity
(H003/H203) and the 1st/2nd Motor Pole Number (H004/H204) according to your motor.
