Automatic gain adjustment part - Sunland inverter

In fact, there are also options for automatic gain adjustment, which generally divide the control response into several levels, such as high echo, medium echo, and low echo, which can be set by the user according to actual needs.

Azimuth Share Buff:

1. Set the share gain of the azimuth ring adjuster;

2. The larger the setting value, the higher the gain, the greater the stiffness, and the smaller the azimuth lag under the same frequency command pulse condition. However, too large a value may cause vibration or overshoot;

3. The parameter value is confirmed by the detailed servo system model and load condition.

Azimuth feedforward gain:

1. Set the feedforward gain of the azimuth ring;

2. The larger the set value, the smaller the azimuth lag under any frequency of command pulses;

3. The feedforward gain of the azimuth ring is large, and the high-speed echo characteristics of the control system are improved, but the orientation of the system will be unstable and the vibration will simply occur;

4. When there is no need for high echo characteristics, this parameter is generally set to 0 to indicate the scale: 0-100%.

Speed Share Gain:

1. Set the share gain of the speed regulator;

2. The larger the setting value, the higher the gain and the greater the stiffness. The parameter values are confirmed according to the detailed servo drive system model and load value. Under normal conditions, the larger the load inertia, the greater the set value;

3. Under the condition that the system does not vibrate, try to set a larger value.

Velocity integration time constant:

1. Set the integration time constant of the speed regulator;

2. The smaller the setting value, the faster the integration speed. The parameter values are checked according to the detailed servo drive system model and load condition. Under normal conditions, the larger the load inertia, the greater the set value;

3. Under the condition that the system does not vibrate, try to set a small value.

Velocity Response Filter:

1. Set the characteristics of the low-pass filter for speed response;

2. 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 set value can be reduced appropriately. If the value is too large, the formation of echoes will be slower, which may cause vibration;

3. The smaller the value, the higher the cut-off frequency, and the faster the speed response. If a higher speed response is required, the setpoint can be reduced appropriately.

*Large Output Torque Setting:

1. Set the internal torque constraint value of the servo motor;

2. The set value is the percentage of extra torque;

3. At any time, this constraint is useful for positioning the end scale;

4. Set the size of the positioning end pulse under the azimuth control method;

5. This parameter provides the basis for the driver to judge whether the positioning is completed under the azimuth control method, when the number of remaining pulses in the azimuth error counter is less than or equal to the set value of this parameter, the driver thinks that the positioning has been completed, and the switch signal in place is ON, otherwise it is OFF;

6. When the azimuth control method is used, the output of the azimuth positioning completion signal, acceleration and deceleration time constant;

7. The setting value indicates the acceleration time of the motor from 0 to 2000 r/min or the deceleration time from 2000 to 0 r/min;

8. The acceleration and deceleration characteristics are linear arrival speed scale;

9. Set the arrival speed;

10. In the non-azimuth control method, if the speed of the motor exceeds the set value, the speed arrival switch signal is ON, otherwise it is OFF;

11. Under the azimuth control method, this parameter is not necessary;

12. It has nothing to do with the direction of rotation.
