1. Position proportional gain
Set the proportional gain of the position ring adjuster; The higher the set value, the higher the gain, the greater the stiffness, and the smaller the position lag under the same frequency command pulse. However, too large a value may cause oscillation or overshoot; The parameter values are determined by the specific servo system model and the load situation.
2. Position feedforward gain
Set the feedforward gain of the position ring; When the set value is larger, it means that the position lag is smaller under any frequency of command pulses; The feedforward gain of the position loop is large, and the high-speed response characteristics of the control system are improved, but the position of the system is unstable and easy to oscillate. When a high response characteristic is not required, this parameter is usually set to 0 to indicate the range: 0-100%.
3. Proportional gain of speed
set the proportional gain of the speed regulator; The higher the setting value, the higher the gain and the greater the stiffness. The parameter values are determined according to the specific servo drive system model and load value. In general, the larger the load inertia, the greater the set value; Under the condition that the system does not oscillate, try to set a large value.
4. Velocity integration time constant
set the integration time constant of the speed regulator; The smaller the setting value, the faster the integration will be. The parameter values are determined according to the specific servo drive system model and load situation. In general, the larger the load inertia, the greater the set value; Under the condition that the system does not oscillate, try to set a small value.
5. Velocity feedback filter factor
Set the characteristics of the low-pass filter for speed feedback; The higher the value, the lower the cut-off frequency and the less noise generated by the motor. If the load inertia is large, the set value can be reduced appropriately. If the value is too large, the response will be slower, which may cause oscillations; The lower the value, the higher the cut-off frequency and the faster the velocity feedback response. If a high speed response is required, the setpoint can be reduced appropriately.
6. Maximum output torque setting
Set the internal torque limit value of the servo motor; The set value is a percentage of the rated torque; At all times, this restriction effectively locates the completion range; Set the pulse range of positioning completion under the position control mode.

Buke servo motor - AC servo motor vibration fault analysis
Mechanical
1. Bearing
The bearing clearance on the lead screw housing is too large after wear, or the bearing roller elements and cages are severely worn due to the lack of grease in the bearing, resulting in excessive loads. After bearing wear, the clearance is too large, which will cause the coaxiality error between the center of the motor rotor and the center of the lead screw.

How to accurately control the torque of the Stepco servo motor - synchronous motor?
1. The indicated value is large (or out of range).
According to the investigation of our staff, this kind of problem often appears in the atmospheric pressure workshop. When we find that the counterweight of the float in the float level gauge is at a low point, the liquid level must be very high at this time, and the glass plate is inconsistent with the indication of the instrument.
