Refer to the industry and theories, GM>6db and PM>30 Deg are the conditions for system stability. This condition is
regarded as a reference for the completion of servo tuning.
In addition, the XY axis needs to maintain the same bandwidth, so that there will be no jitter when moving
simultaneously .
At present, most of the mechanisms of laser machines are double Y column at the bottom, the X axis is mounted on
the double Y column, and the Z axis is mounted on the X axis.
The axis tuning sequence is from axis on top, tuning to the axis in the bottom, complete tuning one axis at a time.
The tuning sequence is as follows: first tune the Z axis, then the X axis, and finally the Y axis, the Y1 axis setting
needs to be the same as Y axis. .
When tuning the X or Y axis, please lower the cutting head to the cutting height first.
2.2.1 2.2.1 Basic axial movement confirmation
Select each axis and enter the password 550, as A shown in the figure below
Set the bandwidth to 40Hz, and enter the ticked parameters in the figure below, as B shown in the figure
below
Confirmwhether the Notch Filter of each axis is closed, as C shown in the figure below
After setting, Jog the axis to see if the axis vibrates, if there is vibration, reduce the bandwidth to 30Hz, and
so on
