1. By pressing the MODE/SET key, select the constant setting mode.
2. Press the UP or DOWN key to set the User constant No.
(for instance, Pn507)
3. Press the DATA/SHIFT key for more than 1 second.
The present user constant data, which is set in step 2 will be displayed. “00100”
4. Press the UP or DOWN key to change the data. “00085”
The display gradually changes by pressing the down key.
5. Press the DATA/SHIFT key more than 1 second. The display flashes and the data will be

Edition 6.0 Chapter 7. Camera Adjustment [1/16]
Chapter 7 Camera Adjustment
Parts Cameras
Two CCD cameras are mounted on the machine for inspection of the parts picked at the first station.
The raw image is captured by the cameras and compared with part data to ensure that the part’s
dimensions are within specified tolerances.
Problems that arise from an incorrectly adjusted camera include displaced parts, high error rates, and
skewed parts. Some other examples of possible reasons for re-calibration are:
• Lens replacement
• Camera replacement

7.1 Parts Camera removal
1. With the machine power OFF, remove the video cables from the cameras.
2. Remove the cameras from the machine.
3. Remove the four mounting bolts from the right hand side of the bracket and carefully remove the
cameras. (The four bolts within the rectangle in figure 2). When replacing the camera, the torque
value for tightening these bolts is 0.98N.m. (10Kgf/cm)

5. When installing the lens unit, apply a small amount of Loctite 425 to the threads and use a 3.92Nm
(“C-Type)” torque wrench to secure the lens unit.
7.2 Camera Settings
1. Make the following amplifier and aperture settings prior to returning the cameras to the machine:

2. Install the lens assembly to the new CCD module, and then remount the camera and lens unit to the
camera bracket.
3. Install the cameras in the machine.
4. Ensuring that the power supply to the machine is OFF, reconnect the video cables to the cameras.
