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.

2.
A message pops up asking for the
removal of the coaxial light and
mapping plate. .
Click Ok once completed.
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.
The mapping information is stored in
C:\system\Log\TableMapping_timestamp*.log file (approx. 459KB).
