Part 2

(2) Insert a block skip mark sequence in the sequence data.

To create a block skip mark sequence line, enter “B” in the “Working Mode”

column of the sequence data and then input the X and Y coordinates of the

center of the block skip mark. In the “PD/Mark Name” column input the

name of the block skip mark data file created in step (1) above.

4.3 Block Skip Specifications

• Block number restrictions

The block number must be between 0 and 255.

• Block skip mark restrictions

Size:

There are no restrictions on size or shape as long as the mark is larger than the

specified area in "scan".

Color:

Must yield a distinct light/dark contrast when viewed by the camera.

Position:

Same as defined for fiducial marks.

Number of marks per board:

Up to 255 marks can be set for one board, including fiducial marks.

2 – 32

• Conditions for reading block skip marks

To specify a block skip mark sequence, input "B" in the "Working Mode" column in

the program editor’s sequence data.

• Conditions for skipping the block

The color in the area specified in "scan" around the center of the given point is

checked and the corresponding block is skipped if the entire area is the color set as

the block skip mark color.

• Processing of sequences skipped in the production program

Sequences set to be skipped in the production program are skipped by the machine

regardless of the skip flag: block, device, or sequence.

These skip settings cannot be cancelled at the machine.

4.4 Cautions When Using the Block Skip Function

• A block skip mark reading sequence can refer to a fiducial mark; however, the

fiducial mark sequence must appear before the block skip mark reading sequence in

the program.

• When block skip marks are input at the machine, if the program being used has no

block skip sequences already, then the marks set at the machine remain valid until

cancelled by the operator.

However, if the production program does contain block skip sequences, then the

settings input at the machine are cleared when a new board is loaded (program

block skip marks take priority).

• In a GL-541E program, the block skip sequences and fiducial mark sequences must

come before all other types of sequences.
