4. Cause and Remedy of Beam Abnormal Approach

Detection

Whenever a beam abnormal approach error is detected, the machine stops in-

stantaneously in an error condition and an error message is issued regardless

of machine operation mode (“RUN”, “PAUSE”, or “STOP”) because machine

protection has top priority.

It is almost impossible for this kind of error to occur.

Whenever this error occurs, it is assumed that Beams A and B might have

collided each other. In this case, contact our marketing department.

Cause of Beam Abnormal Approach Detection

• There is an error in the system.

• A mechanical shift has occurred.

When Beams A and B did not collide with each other, follow the procedure

below to reset the machine to the normal condition.

Note: The P.C.B. in the middle of process (production) cannot be handled

successively. To re-start the operation, open the “AUTO OPN SUB-

MENU” display and follow the semi-automatic operation. (Hierarchi-

(2) Press the [READY] button to unlock the supply cover.

(3) Open the safety bar and the supply and maintenance covers. Then, push

Beams A and B by hand to separate them.

(4) Close the maintenance and supply covers and the safety bar.

the loads.

(7) Press the [RESET] button to cancel the error condition.

The system clear operation is executed.

(8) Press the [READY] button to lock the supply cover.

(9) Press the [ZERO] button to zero each device.

After all devices are zeroed completely, open the “AUTO OPN SUB-

MENU” display and perform the semi-automatic operation to re-start the

operation. (Hierarchical Sequence: “AUTO OPN MODE (PLACE-

5. Cancellation of P.E.C. Recognition Error

When the [RESET] button is pressed after a P.E.C. recognition error has oc-

curred during automatic operation, the “MANUAL ALIGNMENT” display

(Fig. 1.4 or 1.5) appears on the screen.

The display on the screen and the operation procedures differ according to the

mode set at “P.E.C. MANUAL ALIGNMENT MODE”. (Hierarchical Se-

quence: “AUTO OPN MODE (PLACEMENT)” Display → “AUTO OPN SUB-

MENU” Display → “OPERATION MODE” Display → “P.E.C. MANUAL

ALIGNMENT MODE” Display)

P.E.C. Manual Alignment Mode: STANDARD

Fig. 1.4

An image of the captured fiducial mark appears in the crossline section and a

template (identical to the fiducial mark in shape and size) at the center of the

crosslines on the recognition monitor.

(See Fig. 1.5.)

The X/Y beam must be moved until the image of the actual fiducial mark and

the template overlap each other at the center of the crosslines. (Manual Align-

ment)
