Setting Change And Measurement For Workpiece And Application - Panasonic HL-D3 Series User Manual

3-3-2 Setting Change and Measurement for
Workpiece and Application
Major setting values at shipment from the factory are as follows:
Measurement
range
Unit detection
time
Measurement
mode
Beam power
control count
Sampling cycle
Shape calculation
setting
Number of average
movements
Upper/lower limit
judgment value
OUT measurement
operation
*1 It is the actual value that can be checked by
when the head is connected.
For other settings at the shipment from the factory, refer to
and Default Values" (page 4-19).
Change settings according to your use. Examples are shown below.
 If a workpiece does not have sufficient light
intensity in default settings
Place a workpice at the correct distance and perform "Get detected light intensity
image" several times. If the beam shape is not displayed, the sensitivity condition
may not be suitable for the workpiece surface or the reflection rate. Increase the
"Unit detection time" (200 us, etc.) and check it again.
(In this case, the sampling cycle is longer.)
For details of the function, refer to
 Frequent alarms occur due to variation of light
intensity in the default settings
If the surface has a fine work or stripe pattern, the light reception status may be
unstable due to rough segment width. Set the "Beam pwr ctrl unit." of "Multi-zone
B.C. " to "All points", and check it again.
(In this case, the sampling cycle is longer.)
For details of the function, refer to "4-4-3 Setting for Measurement Mode·".
