14.3.2. Skew compensation

Skew means compensating the skew occurred horizontally in the X-axis frame against the

Y1-axis and Y2-axis after movement of equipment. This must be done upon initial

installation and after movement of the equipment to a new location. Method of skew

compensation for Y-axis is as follows;

Caution Skew means compensating the skew occurred horizontally

in the X-axis frame against the Y1-axis and Y2-axis after

movement of equipment. This must be done upon initial

installation and after movement of the equipment to a new

location. Method of skew compensation for Y-axis is as

follows;

 First, move the X frame manually to the center of equipment.

 Click on the <Skew compensation> button. Automatic homing on Z-axis is performed,

Y1-axis motor rotates and moves X frame until detecting the Y home sensor. Once the

home sensor has been detected, move to the Y-axis movement distance (Y Stroke) in

the opposite direction, and move to the opposite direction again until the Y Home

sensor is detected.

 Then, ‘Skew’ information is shown as follows, and asks whether to apply the value.

 <1. Fid. Scale Mark Position> button

Set the position of the reference fiducial mark located at the top surface of the ANC.

When performing the scale calibration of the fiducial camera by using the calibration

tool, place the calibration tool at the position for the calibration tool on the front ANC.

The following is the process that performs teaching of the calibration tool placed on

the top surface of the ANC by using the fiducial camera.

1. When performing the mark setup, select the gantry and click the <1. Fid. Scale

Mark Position> button. If the following screen appears, click the <Move> button

in the <Teach> group.

Then the fiducial camera moves to the corresponding position. The mark ID of

Gantry 1 is fixed as No. "7", and No. "8" for Gantry 2.

2. If the corresponding fiducial mark cannot be recognized correctly, teach the

position of the fiducial mark at the center of the calibration tool placed on the top

surface of the ANC. The size of the fiducial mark of the calibration tool is 1.6 mm.

3. If the fiducial mark position teaching is performed accurately, click the <Update>

button to apply the changed value.
