6.6.3 Skipping holders (from NXT V3.00)
Use this function to skip using a holder for a head on a module. This function makes it
possible to not use a specified holder in order to avoid using a holder at which frequent
errors occur during production or for which air leakage or clogging problems prevent normal
use. In addition, the holder skip function serves as a calibration information backup
measure. It is important to note the following points about this function.
• A holder skip status is canceled when a head change occurs.
• A holder for which calibration using a jig nozzle has not been completed cannot
be skipped.
• The holder skip function cannot be used for the H01 head, or in cases where a
skip would leave no remaining nozzles for production.
• The holder skip function cannot be used in cases where the Q-axis and/or R-
axis are not operating normally or in cases such as mechanical valve failure, in
which other holders remain unaffected.
• Recovery processing occurs for parts that were supposed to be placed by the
skipped holder. Therefore, the skip function reduces throughput.
• When skipping a holder due to a holder failure, verify that the other holders are
operating normally.
• The nozzle in the skipped holder is returned to the nozzle station. If the nozzle
cannot be returned to the station due to some failure, remove the nozzle by
hand.
• It is possible that an accuracy deviation may occur using a head after a failed
holder has been skipped.
Skipping a holder on a head.
1. If START has not yet been pushed and the main screen is displayed after turning on the
power, push START to turn on the power to the head. Then stop the machine.
2. Ensure that the main screen is displayed at the module.
3. Start MEdit and select [Holder skip] from the [Tool] menu. The [Holder skip] dialog box
is displayed.
4. Select the factory, line, NXT machine, and the module in the [Module list]. A list of the
available holders on the head is displayed in the [Holder lists].
5. Select the check box for the holder to be skipped.
Note: Check boxes for multiple holders can be selected by using the [Shift] or [Ctrl] key. First, hold
down the [Shift] or [Ctrl] key and left-click on the number of the desired holders to highlight
those holders. Then, release the [Shift] or [Ctrl] key and select the check box for any one of
the highlighted holders. This will automatically select the check boxes for all highlighted
holders.
6. Click [Set] to apply the skip setting and then close MEdit.
7. Push START at the module in question to restart production. Production is continued
without using the skipped holder.
Note: If the skipped holder is holding a part, discard it. Return the nozzle to the nozzle station if
necessary.

NXT Programming Manual 169
When holders are specified to be skipped, the skipped holders are displayed in the
operation panel on the module. Confirm that the holder to be skipped is correct.
Clearing a holder skip setting for a head.
1. Push CYCLE STOP at the module with the skipped holder to stop production.
2. Ensure that the main screen is displayed at the module.
3. Start MEdit and select [Holder skip] from the [Tool] menu. The [Holder skip] dialog box
is displayed.
4. Select the factory, line, NXT machine, and the module in the [Module list]. A list of the
available holders on the head is displayed in the [Holder lists].
5. Clear the check box for the holder being skipped to clear to skip setting.
6. Click [Set] to apply the cleared skip setting and then close MEdit.
7. Push START at the module in question to restart production. Production is continued
using the previously skipped holder.

6.7 Testing Jobs (from NXT V3.10)
6.7.1 Introduction
The job test function enables users to view and edit jobs on the machine prior to starting
production. By doing this, errors that occur during the beginning of production for a new job
can be greatly reduced. There are two job test modes and the items checked by each mode
are different. Information about these two modes are provided below.
Simulation
The placement position for a specified sequence is captured using the mark camera and
the panel pattern is compared graphically with the part image (wire frame) in MEdit. This
allows the operator to check for any placement position deviations and problems with the
placing angle. In addition, it is possible to confirm that the part type is roughly correct by
comparing the wire frame of the part graphic to the actual pad arrangement. If there are
any calculated placing deviations, they can be corrected easily in MEdit and be reflected
back to the job.
The main items checked by this mode are fiducials, placement position, orientation, and
part types compared to the pads. Actual parts are not required to perform this test, just an
actual panel is required. If any problems with these items are located, corrections can be
made and checked again.
Place & Check
Parts are picked, vision processed and placed on the panel. Once a part is placed, the
mark camera takes an image of the position and that image is then displayed in MEdit with
a part graphic overlay in MEdit. This allows the operator to check for pickup errors, vision
errors, actual placement position deviations and problems with the placing angle. If there
are any errors, they can be corrected in MEdit and be reflected back to the job.
The main items checked by this mode are fiducials, feeding, feeding direction, vision data,
placing data, actual placement position, and orientation. Actual parts are required to
perform this test as well as an actual panel. If any problems with these items are located,
corrections can be made and checked again.
