Step 7
1.
Clean the mapping plate using a
piece of lint free cloth and alcohol.
Dust and fingerprints can distort
images and cause the mapping to
fail.
2.
Align the left edge of the mapping
plate to the left edge of the
conveyor´s front top clamp.
Step 8
1.
Close the machine cover.
2.
Click OK. The machine locks the
cover, the table raises to clamp
the plate, and th
e camera starts to
move to the bottom right corner of
the plate.
Step 9
1.
The plate´s bottom right hand
cross fiducial comes into view.
Click on the cross to centre the
cross to the FOV.
2.
Set 2D M-Ring_G light between
10 ~ 20 (recommend 15) and all
other lighting values to 0.

Step 10
1.
Click on Focus icon.
2.
Set value between 50 ~ 60.
3.
Click Continue to start the teach
table mapping process.
The progress of the mapping is
continuously reported.
NOTICE
After about 31.5 minutes, at 50% completion, the table towers, the stopper rises, and the
plate will move forward to the stopper to continue the second stage of the mapping. Do
not be alarmed by this sudden movement. No user intervention is required.
Step 11
1.
After about 63 minutes, a
message pops up to report if the
teach process is completed.
Click OK.
2.
At the next message,
click OK to continue with
verification (see section “4.4.2
Table Mapping: Verify”)
or Cancel to end mapping teach.
NOTICE
If the mapping fails, clean the plate and repeat the procedure. Mapping failures are
caused by a failure to read a fiducial on the plate – usually caused by fingerprint
smudges on the fiducials. Verification of the mapping results is necessary after a
successful Teach.
1. Lower the conveyor lift cable.
2. Open the machine cover.
3. Remove the mapping plate.
4. Uninstall the coaxial light.
5. Reconnect the Low Ring light connector.
6. Open the machine cover.
NOTICE
The mapping information is stored in
C:\system\Log\TableMapping_timestamp*.log file (approx. 459KB).
The Delta of Gantry to fiducials` positions should be ≤ 20µm (0.020mm).

4.4.2 Table Mapping: Verify
● For verification of positional accuracy of the camera across the work area.
● Verify saves time. It takes only 5.5 minutes compared to 63 minutes in Teach.
● The procedure is similar to the Teach procedure.
● Verify the table mapping again if:
– The machine is already calibrated but is moved.
– The positional accuracy of the camera across the work area is suspect.
– Maintenance is performed on the gantry axes e.g. greasing.
Step 1
1. Go to DiagnosticPage
2.
Click System Test.
3.
Go to Utility, Table Mapping
Calibration
4.
Under Option, select Teach.
5.
Click Start.
6.
A message asking for the
mapping data file pops up.
7.
Copy the "mp_mess.dat" file to
the "c:\system\AS Table
Map Offset\" folder.
Switch back to ProcessLens GUI,
click Yes.
