1.5 Nozzle Statistical Processing
The machine has a statistical processing function which monitors the number of nozzle
errors that occur, and automatically skips any nozzle that generates errors frequently.
This statistical processing function is called the nozzle skip function.
1.5.1 Nozzle Skip Method
Nozzle skip can be set in Proper data. (Hereafter referred to as “auto skip”.) This
function is effective for detecting dirtied nozzles, or when there are too many rejected
parts.
Nozzle skip can also be set manually. This is useful when there are damaged nozzles on
the nozzle holder.
Auto-skip
When there is a nozzle whose errors exceed the error rate set in Proper data (i.e. a
picking error or vision processing error), that nozzle will be skipped and the nozzle
number will appear at the monitor.
There is also a limit (set in Proper data) to the number of nozzles which can be skipped
for each nozzle position. If this limit is reached, the machine stops.
The “Skip” status of the nozzle is cleared when operation is restarted after stopping due
to the nozzle skip limit, or can be changed by the operator at the machine using the
following procedure.
Manual Nozzle Skip
Pressing the [SET], [MANUAL] and [NOZZLE SKIP] command function keys in that
order will either set or cancel the nozzle skip, depending on the context of the situation.
If the nozzle skip has been set manually it must be canceled manually as well and cannot
be used again.
Setting the Error Rate
This error rate determines when a nozzle will be skipped. For each individual nozzle,
the number of errors in the most recent 16 placements is counted and if this rate exceeds
the error rate that has been set then the nozzle will be skipped automatically. For
example, if this value is set at 1 and any one nozzle is defective more than about 6% of
the time (i.e., 1/16 of the time), that nozzle will be skipped.

How to Set the Proper Data
The appropriate Proper data settings are shown below.
129 Skip Number: The number entered here will become the error rate number
described above.
130 Skip Nozzle 1: This sets the maximum permissible number of defective No. 1
nozzles.
131 Skip Nozzle 2: This sets the maximum permissible number of defective No. 2
nozzles.
132 Skip Nozzle 3: This sets the maximum permissible number of defective No. 3
nozzles.
133 Skip Nozzle 4: This sets the maximum permissible number of defective No. 4
nozzles.
134 Skip Nozzle 5: This sets the maximum permissible number of defective No. 5
nozzles.
135 Skip Nozzle 6: This sets the maximum permissible number of defective No. 6
nozzles.
Display Monitor
When nozzle skip and manual nozzle skip take place, information on the skipped
nozzles will be displayed on the screen.
The yellow display indicates a nozzle has been automatically skipped and the blue
display indicates a nozzle has been skipped manually.
Points to Remember When Using Nozzle Skip
When the manual skip is set during production of a board, the manual skip will be
immediately effective and the part currently held by that nozzle will not be placed. To
avoid this, set the skip between boards.

1.6 Setting the Production Quantity
1.6.1 Scheduled Production Run
The operator can set the scheduled production run quantity either in the program or by
using the [PROGRAM] - [QTY. SET] command.
When specified in the program, transmit the program from the host computer to the
machine.
If the number has been set in the program, the program must be transmitted from the
host computer to the machine.
Moreover, once the scheduled production run is completed, the program must be
retransmitted for the next run, so the machine command is the method more often used.
Caution: The scheduled production run quantity can be set from 0 to 65,000. If 0 is set, the
machine will continue to operate indefinitely.
When the scheduled production run is completed the machine stops and displays the
messages “Production Complete” and the RESET button flashes.
When the RESET button is pressed, the message “Ready” appears. If the operator tries to
start automatic operation at this point the message “Production Complete” appears and
automatic operation cannot be executed. To continue production the operator should
enter the number which is bigger than the completed board counter or 0 as the scheduled
production number.
Cautions:
• If production is ended before reaching the program’s scheduled production quantity, both
the “scheduled production quantity” and the “completed board count” values are stored in
memory even if another program is then run. When the original program is subsequently
run again, operation resumes from the “completed board count” and continues until the
“scheduled production quantity” is reached. The machine stops at that time.
• The number of completed boards (“completed board count”) is only counted in “offline”
communications with the host computer.
