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.

6.7.2 Testing a job using simulation mode

Use this mode to perform a basic check of the part types, placing positions and orientation.

Starting simulation mode.

1. Transmit the job to be tested to the machine and wait for the main screen to display on

all of the operation panels for the modules.

2. Start MEdit and log on if necessary.

3. Click [Open Current Job] from the [File] menu. The [Acquire current production job]

dialog box displays.

4. Double-click the line with the machine for the job to be tested and then double-click the

machine name to display the modules. Select the module on which the job is to be

tested. The name of the job in the module is automatically displayed in the [Job] group

box.

5. If necessary, select the lane on the module with the job to be tested.

6. Click [OK] and the specified data from the job is opened.

7. Select [Job Test] - [Simulation] from the [Tool] menu. The background color of the

operation panel for the module in question turns violet to indicate that that module is in

a test mode.
