 <FIND LIMIT ALL AXIS> button

Finds the Limits of all axes.

 <Home Info.> Group

If the mirror axis is selected, the <Home Offset> edit box will be enabled. It is

used to perform calibration for the mirror axis.

 <Update> button

Transmits the set data to the machine and closes the dialog box.

 <Cancel> button

Ignores the set data and closes the dialog box.

Caution

If calibration is done again, the machine might not operate

properly unless the items related to the equipment position,

such as pick up position, ANC, placement origin are taught

again as the home position is changed.

After calibration, be sure to teach the items related to

position again.

1.2.2. 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 Compensation> must be performed before ‘return to

origin’ following initial installation or movement of

equipment. Otherwise, the equipment may be damaged

during operation.

 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.

 Click on the <Yes(Y)> button and <Update> button, and then homing of the

equipment is newly done in accordance with the applied skew information.

1.2.3. Fiducial Camera Scale Calibration

If the fiducial camera is not calibrated, the rest of the buttons are disabled.

 <1. Fid> button

Teach the position of the Reference fiducial mark located at the top surface of

the ANC.

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

placed on the top surface of the ANC by using the Reference fiducial camera.

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

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.
