      Servo driver related parameter setting method

      Position feedforward gain: set the feedforward gain of the positioning loop. The larger the set value is, the smaller the position delay isand the larger the feedforward gain of the position loop is, the high-speed response of the control system will rise, but the position of the system is unstable and prone to oscillation. When high response characteristics are not required, this parameter is usually set to 0, indicating the range of 0 ~ 100%.
