5.3.2 Adjust processing acceleration
The speed of high-clicking can be set as high as possible, such as 500mm / s.
When complete a click, moving distance is required to be long enough, in order to
ensure that speed can be accelerated to the setting value.
Observe the torque curve of click movement by the servo debugging software.
For example, if the maximum torque is less than 80%, appropriately increase the
processing acceleration; if the maximum torque is higher than 80%, appropriately
reduce the processing acceleration.
Adjust the acceleration, until the maximum torque nearly is 80%. Generally, the
processing acceleration withstood by lead screw is not more than 0.5G. Rack and pinion
generally is not more than 2G.
5.3.3 Adjust move acceleration
Directly fill the maximum acceleration calculated by ServoTool software, or
appropriately increase the move acceleration on the basis of processing acceleration,
for example, set as 1.5 to 2 times of the processing acceleration. It’s required that the
maximum torque of the servo is not more than 150%, and the mechanical structure
does not occure significant deformation and vibration under this acceleration. Screw
affordable air movement acceleration generally is not more than 0.5G. Rack and
pinion generally is not more than 2G.
5.3.4 Adjust FIR frequency
When you set up the FIR frequency parameter, you can cut a sample image. It’s
proposed that, at the beginning, turn down the laser power, and mark the plate. Observe
the accuracy of marking path. Cutting sample image includes various sized small
round, regular 6-gon, regular 12-gon, star, rectangular, etc. As shown below:
Adjust the FIR frequency as high as possible in the case of no affecting the
accuracy. It is required the corner does not generate waves when cutting a rectangle,
polygon and star. It can be set according to experienced value of the following table, Or
debug the FIR frequency within the upper and lower two ranges after determining a
processing acceleration. These two parameters, processing acceleration and FIR
