Some parameter settings for the servo motor driver:
1. Increase the proportion of positions.
A higher proportional gain setting for the position loop regulator results in higher gain, greater rigidity, and less position hysteresis under the same frequency command pulse conditions. However, excessively high values may cause vibration or over-adjustment. The parameter values are determined by the specific servo system model and load conditions.
II. Position feedforward benefits.
A higher feedforward gain setting for the position loop results in smaller position hysteresis under command pulses of any frequency, leading to a higher high-speed response characteristic of the control system. However, when the system's position is unstable and a high-response characteristic that easily generates vibration is not required, this parameter is usually set to 0. The range is 0-100%.
Third, the speed ratio increases.
A higher proportional gain setting for the speed regulator results in higher gain and greater rigidity. The parameter value depends on the specific servo drive system model and load. Generally, the greater the load inertia, the higher the setting value should be; assuming no system vibration, set the value as high as possible.

IV. Velocity point time constant.
The smaller the integral time constant setting of the speed regulator, the faster the integral speed. The parameter value depends on the specific servo drive system model and load conditions. Generally speaking, the greater the load inertia, the larger the setting value; when the system is not vibrating, try to set the smallest possible value.
V. Speed Feedback Filter.
Set the speed feedback to low. A higher filter characteristic value results in a lower cutoff frequency and less noise from the motor. If the load inertia is large, the set value can be appropriately reduced. A value that is too large will result in a slow response and may cause vibration. A lower value results in a higher cutoff frequency and faster feedback speed. If a high-speed response is required, the set value can be adjusted.
6. Set the maximum output torque.
Set the internal torque limit value of the servo motor; the setting value is a percentage of the rated torque; this limit can effectively position the completed range at any time; set the positioning completion pulse range under position control mode.
Servo drive control mode selection:
1. If the speed and position of the motor are not required, and only a certain torque needs to be output, select the torque mode.
2. If a certain level of accuracy is required for position and speed, and real-time torque is not a major concern, then using torque mode is inconvenient. It is best to use speed or position mode instead.
3. If the high-level controller has good closed-loop control capabilities, speed control will be more effective. If the requirements are not very high or there are basically no real-time requirements, then position control mode should be used.
