3.5.5 Marker
The reference marker provided on the head assembly of the YV180X can
be used to minimize unwanted effects on recognition accuracy due to
mechanical changes over time. The following explains the method for
adjusting the reference marker offset values.
1 Run the “Multi Camera” − “Marker” command.
1. Select <3/3/B1 ADJUST TARGET> − ”Multi Camera” - “Marker” and
press the [ENTER] key.
2. Select the conveyor table and the camera No. by pressing the [ENTER]
key.
The A-table multi-vision camera is designated “Cam. 5” and the B-table
multi-vision camera “Cam. 6”.

2 Check safety, then press the [ENTER] key.
The head assembly moves and passes repeatedly over the multi-vision
camera and the marker offset is measured. The results (Marker 2 on the
YV180X) are then displayed in the upper right corner of the operation
monitor.

5 Save the data.
Select <B2 SAVE DATA> or <B0 SAVE & QUIT> and press the [ENTER]
key. (To quit without saving, select <B3 RECOVER ADJUST> or <B7
QUIT> and press the [ENTER] key.)
Reference
The marker offset values adjusted here are stored in “Precision” - “MultiCam Marker” in
MCH_DATA mode. (See “6.1” in Chapter 3.)
6 Check the data.
Enter the Adjust Assistant mode in DATA Manager and run the VISION
TEST command for the marker using any component data (not necessary to
actually pick up acomponent with the nozzle) and check that the [Marker
2] XY data values displayed on the lower part the Adjust Assistant screen
are within ±0.005.

3.6 R-axis accuracy offset
This is the angular offset for the R-axis that rotates each nozzle shaft to
mount a component. When you select <3/2/A1 SELECT TARGET > - ”R
Axis Accuracy” and press the [ENTER] key, the current offset settings for
mounting angles of 0, 180, 90 and -90 degrees are displayed as shown
below.

When the multi-vision camera with the reference mounting angle specified
at 0 degrees is used, mountings at 90, 180 and -90 degrees might deviate
slightly. This deviation or offset can be corrected with the R Axis Accuracy
command in the MCH_ADJUST mode, in which the multi-vision camera
recognizes an SOP component at each mounting angle to obtain the offset
with respect to the recognition result at 0 degrees. Since the parameter at 0
degrees is used as a reference, it is always set to 0.00 degrees.
