Note:
The notch filter is the lag factor for the servo system, so, if the center frequency of control width is
large, the vibration may be strengthened. It is recommended to increase the width unit it meets the
requirements.
The relationship between the Q value, width and depth is as below:
 Q value of the notch filter=Center frequency of the notch wave /Width of the notch wave;
 If the width of the notch is 0, the width of the filter is the deviation between two frequencies when
the power of the center frequency drops to -3dB;
 The depth of the filter means the ratio of input and output, and its power spectrum strength
attenuates by 20log (P1.25%, P1.28%, P1.31%, P1.34%) dB.

7.4 Gain switching function
Gain switching operation is performed through internal data or external signal:
1) Can switch to lower gain to suppress vibration in the state when the motor is stopped;
2) Can switch to higher gain to shorten the positioning time in the state the motor is stop;
3) Can switch to high gain to obtain better command follow-up performance in the state when the
motor is running.
4) Can switch between different gain settings through external signal according to the conditions of
load, equipment and so on.
