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 checkbox for the holder to be skipped.
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.
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 checkbox 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.
