Parameter setting method of servo motor driver

1. Position proportional gain.

The larger the setting value, the higher the gain and the greater the stiffness. Under the same frequency command pulse condition, the position lag will be smaller. However, too large a value may cause oscillation or overshoot; the parameter value is determined by the specific servo system model and load conditions.

2. Position feedforward gain.

The larger the setting value, the smaller the position lag under any frequency command pulse; large feedforward gain of the position loop make strong characteristic of high-speed response of the control system, but will make the position of the system unstable and easy to oscillate; when high response characteristics are not required, this parameter is usually set to 0 to indicate the range: 0~100%.

3. Speed proportional gain.

The larger the setting value, the higher the gain and the greater the stiffness. The parameter value is determined according to the specific servo drive system model and load value. In general, the larger the load inertia, the larger the set value; under the condition that the system does not oscillate, try to set a larger value.
