 The Method of Setting Parameters of Servo Motor Drive

When in a new system, the parameters of servo motor drive cannot work, first set the position gain to ensure that the motor is noise-free, and set it as large as possible. The momentum of inertia ratio is also very important, and you can refer to the value you have set. Set the speed gain and speed integral time to ensure continuous and position accuracy control during low-speed operation.

1. Speed proportional gain of servo motor driver

Set the proportional gain of the speed regulator. The larger the setting value, the higher the gain and the greater the stiffness. The parameter value of the servo motor drive is determined according to the specific servo drive system model and load value. Generally, the greater the load inertia, the greater the setting value. Under the condition that the system does not oscillate, try to set a larger value.

2. Speed integral time constant of servo motor driver

Set the integral time constant of the speed regulator. The smaller the setting value, the faster the integral speed. The parameter values are determined according to the specific servo drive system model and load conditions. Generally, the greater the load inertia of the servo motor drive, the greater the setting value. Under the condition that the system does not oscillate, try to set a smaller value.

3. Speed feedback filter factor of servo motor driver

Set the characteristics of the speed feedback low-pass filter. The larger the value, the lower the cut-off frequency and the smaller the noise generated by the motor. If the load inertia is large, the setting value can be appropriately reduced. If the value of the servo motor driver is too large, it will slow down the response and may cause oscillation. The smaller the value, the higher the cut-off frequency and the faster the speed feedback response. If you need a high speed response, you can appropriately reduce the setting value.
