14.3.8.10. R-Axis Offset Calibration

If the recognized angle and placement angle of the R axis are different, the R axis error

cannot be compensated through the Vision. Therefore, the placement accuracy decreases.

Therefore, perform R axis offset calibration to minimize such error by compensating an

approximate value with the R axis motion data.

To perform this Calibration, first confirm that the CNT20 nozzle is installed in ANC Hole

No.1 before operation.

The following is the procedure to calibrate the ‘R-Axis Offset’:

1. If the CNT20 nozzle is not installed, click the <Nozzle Prepare> button to manually

insert the CNT20 nozzle into ANC Hole No.1.

2. If the <16. R-Axis Offset> is clicked after selecting the <Automatic Next> check box,

calibration is performed for the selected gantry automatically.

3. Recognize the 2 fiducial marks on the bottom surface of the calibration tool by using

the fly camera while rotating the head from -360 degrees to 360 degrees at 5 degree

intervals.

4. If the calibration procedure is completed for all heads normally, the result is displayed

as shown in the following figure.

The measurement result can be confirmed in the R Axis dialog box.

Machine Calibration

Memo The reference values for the calibration of the R-Axis Offset is as

follows.

 Real Max(Min): The Max.(Min.) offset between command value

and calibration value

Head1~Head10 : -0.5 ~ 0.5 (deg)

 Err Max(Min) The Max.(Min.) offset between compensation

value and calibration value

Head1~Head10 : -0.2 ~ 0.2 (deg)
