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.

How to maintain the servo motor driver?

In order to prolong the lifespanof the servo system, you should pay attention to the following aspects. For the operating environment of the system, the temperature, humidity, dust, vibration and input voltage need to be considered. Please regularly clean the ventilation system of the numerical control device. Always check whether the cooling fans on the numerical control device are working properly. It should be inspected and cleaned every six months or a quarter depending on the environment of the workshop.
