1.12.10 Board Check Conditions
When automatic operation or step operation is started, movement to the board check
position takes place and a board check is carried out under the following circumstances.
1. At restart after an emergency stop.
2. At restart after selection of the I/O check command.
3. At restart after XY-table board unclamping (excluding unclamping that takes place in
the context of a series of operations such as when a board is replaced).
4. When the power is turned on.
5. At restart after loader command selection (excluding the loading position command).
6. At restart after a change in the operation mode.
Product, Idle, Simulate
7. If the number of boards being managed by the software differs from the board check
result and the F6 key is used to temporarily quit automatic operation.
8. If an error occurs during board transport or changeover that has caused automatic
operation to be quit.
1.12.11 Placement Check Function
Using the live image display of the mark camera, an image of the placed parts can be
output to the image processing monitor and the parts placement status can be checked
visually.
Checking of placed parts is performed using the following procedure.
[1] Set the placement check function.
[2] Terminate board production.
[3] Check placed parts. (Page PCK)
[4] Continue production.
Setting the placement check function
Prior to terminating board production (before performing the final placement sequence),
select [PLT CHK STOP] (see page 150).
When desiring to cancel this setting, select one of the other production modes (see page
150).
Board production after setting the function
If the placement check functions is set, "Plmt Chk" is displayed in Status (P Mode) and
"Placement check stop processing" is displayed in the Help area. After production is
terminated, the placement check command (Page PCK) automatically becomes effective.

Placement check screen (Page PCK)
The "Page PCK" screen is shown below.
In the first area, information on the sequence currently displayed in the monitor is shown
(only for parts that have already been placed). Whenever any of the data are unspecified,
a "*" is displayed instead of a numerical value.
F1: GAIN/OFFSET This executes the Gain/Offset command for the mark camera. The
Proper Data values are not changed by this command. This is
effective only when in Page PCK.
F2: CAM ORG POS If pressed continuously, the cam shaft is returned to its origin
position.
F4: SEQ. NO Carries out sequence number specification.
F6: RECOVER Terminates the placement check and returns to Page 100.
START switch: This blinks if the cam shaft is at the origin position and the process
has not been completed up to the final sequence. If the START
switch is pressed, the XY table moves in the sequence order.
Resuming Production after Completing the Placement Check
When the placement check has been completed, production returns to the normal
continuous production (P Mode: Product). If the START switch is pressed, the board
was checked is unloaded, and a new board is loaded. The placement check function is
not automatically effective upon completion of board loading.

Cautions
1. The F mark and B mark cannot be checked using this function. Only placed parts are valid.
2. In Page PCK, the mark is not reread. If the board is not clamped correctly due to Z axis
inching or abnormalities in the air pressure, coordinate deviation can occur.
3. Changes in the Gain/Offset are effective only in Page PCK. Once you exit from Page PCK,
the Gain/Offset values return to their original settings.
4. Single-board production cannot be stopped during placement check stop processing.
1.12.12 Function for Checking Board Displacement Using Fiducial
Marks
The offset value when reading the fiducial mark (the distance between the mark camera's
center and the fiducial mark) shows the amount of board displacement, and when
necessary, the machine will be stopped. This is effective in cases where parts are
mounted on the bottom surface of the boards and there is danger of interference between
the mounted parts and backup pins during production. However, it is not possible to
prevent such interference in advance.
If the machine is error-stopped, check for interference between the mounted parts and
any backup pins. A decision can then be made either to resume production or cancel
production and unload the board.
If you continue production, it is necessary to adjust the positions of the boards. Failure
to do this could result in another error stop. The permissible values for board
displacement deviation are set in the production program.
Pcb_data
Pcb_position_tolerance (0 to 12.49 mm) = 0.
The default value is 0 (the function is OFF).
Screen Display of Machine Stop Time
"Mark Check Error: Seq_no"
"Check the board's status."
"The mark correction amount exceeded the permissible value. Adjust the board
position and restart the machine, or remove the board."
