After setting, exposure and gain time corresponding to the percentages
automatically shows.
Note: Too large percentage of Expose results in low captured frame rate. Thus, Expose should be
set properly.
After setting Expose, you need to consider whether to increase the shoot delay
time(unit: ms).
In general, the requirement of shoot delay time is as the follows:
Shoot Delay Time ＞ 100ms + Exposure Time
Among them, 100ms refer to the machine’s stop time.
Example
If Expose is set to 7%, the corresponding exposure time is 0.035s (35ms). Thus, it is
reasonable to set the shoot delay time to 200ms.
4.2. Debug CCD and the Machine
Focal length, magnification and offset are fixed after the machine tool is installed. If
the machine tool is replaced or repaired (e.g. the camera or lens is reinstalled), these
three values need to be re-measured. That is, debugging CCD and the machine tool is
required.
To debug CCD and the machine tool, do the following:
1. Click Basic Setting → Set and check Setting ON.
2. Measure the focal length
3. Measure the magnification
4. Measure the offset between the spindle and CCD
4.2.1. Measure the Focal Length
Aim of the operation: Before shooting, X-axis and Y-axis move to the shooting point
and Z-axis moves to the focal height.
To measure the focal length, do the following:
1. Manually move Z-axis until the camera can take a clear picture.
2. Enable X10 with handwheel to move Z-axis until Z-axis finds the clearest
position.
