6. Open the Sequence Data in the relevant program.

7. At the beginning of the sequence, insert the same number of lines as the number of

blocks.

8. Specify the following setting items at the inserted lines:

Block#: Enter the block number corresponding to that block skip mark.

Work Mode: Select “B”.

X: Enter the X-coordinate for that block skip mark.

Y: Enter the Y-coordinate for that block skip mark.

PD/Mark Name: Enter the block skip mark name (specified at step 5 above).

9. Overwrite and save the data.

(3) Global Skip Mark

This function has been introduced to control the number of times block skip marks are

read by the machine on a multiblock board. Standard production involves the placing of

all the blocks on a multi-block board, the machine therefore reads all the block skip

marks. In a production situation where the skipping of blocks is rare, a global skip mark

should be used. By using a global skip mark, the machine has only to read one block

skip mark instead of reading all the block skip marks on the board.

• Definition

The global skip mark is defined as the block skip mark with block number 0. (Settings

for standard block skip marks are 1 to 255.)

• Setting a global skip mark

Global skip mark should be placed before block skip marks of 1 ~ n (Place the global

skip mark at the top of the block skip mark reading sequences).

• Global Skip Mark Usage

If the global skip mark is present (the machine detects a global skip mark), the machine

proceeds to read all the block skip marks and skips blocks as necessary.

If the global skip mark is not present (the machine does not detect a global skip mark),

the machine proceeds with the placing of parts on all the blocks without reading the

block skip mark of each block.

• Proper Data Settings

It is necessary to make the following Proper data settings to enable the global skip

mark function.

11. Machine_Status A: ???? ???? X??? ????

X: "1" to enable the global skip function

X: "0" to disable the global skip function

• The following restrictions apply when using the global skip function.

It is not possible to skip or cancel the global skip mark (skip mark with block 0) at the

machine using commands. If the Proper data item "Machine_Status A" is set to "0" (at

the bit indicated above) and a production program including a global skip mark is

used, the machine still reads the specified global skip mark area, however the global

skip mark is not processed.

If multiple global skip marks have been set, the first mark is the mark which is treated

as the global skip mark. Any global skip marks after this are ignored.

(4) Board Check Function Using Block Skip Marks

If there is even one block skipped as a result of block skip mark recognition, the XY-table

will move to the loading position and the RESET button will be enabled. When the

RESET button is enabled, the block skip board can be replaced or cleared off.

After RESET is pressed the START button will be enabled. If the START button is then

pressed, fiducial mark and block skip mark acquisition will start again from the

beginning.

This function is premised on the idea that several small boards are loaded on a pallet and

that one board is considered as a block. In addition, if board replacement is carried out

after the machine stops, it must be possible for a board to be replaced with the pallet in

the clamped status. This is not necessary if a board is cleared off.

This is an optional function. It can be enabled by setting the third bit in the Proper data

item Machine_Status_A to “1”.

Machine_Status_A ???? ???? ???? ?1??

If even one block is skipped as a result of block skip mark recognition, the following

screen will be displayed.

Part 2 Chapter 1 Basic Operation

Edition 1.1 2-1-81 CP643E System Reference

If all blocks are skipped then only the following message will display.

“All Block Skip”

Skipped blocks can be verified on the screen shown above. If there are more than 40

blocks the blocks can be verified by pressing F1 and F2.

Precautions

• Activation of this option is limited to cases where the block skip board is to be

replaced and reused. Of course it must be possible for the block to be replaced. Since

a block on a multi-block board cannot be replaced, this function would serve no

purpose even if it was enabled.

• If this option has been enabled the block skip board must either be replaced or cleared

off with the pallet. If the board is removed without being replaced, operation cannot

be guaranteed. Since what will happen as a result of block skip mark recognition for a

block on a pallet on which there is no board can be determined, it is possible that parts

will be placed in the area where there is no board.

• If a block is skipped using the block skip command on the machine the skip status will

not be cleared even if RESET is pressed. However, the block skip status will be cleared

for a block that is skipped as a result of block skip mark recognition. If the block skip

command on the machine is executed while block skip mark acquisition is in progress

then those blocks that have been skipped up to that point as a result of block skip

mark recognition will not be cleared either even if RESET is pressed.
