Mode 4 One of the magazines is used for parts
resupply and the other is used for
production. When parts run out at the
production magazine, the drawer with
the empty tray is unloaded to slot 12 of
the resupply magazine. A new tray is
then moved from the resupply
magazine to a slot in the production
magazine and then production
continues.

Mode 1: Producing panels with many part types
Features
• When producing with several different part types that exceed 12 slots, the job is
set up to use both magazines as one.
• Production efficiency is improved by setting alternate trays at empty slots.
When setting alternate trays inside the same magazine, partially used trays do
not occur. However, when setting alternate feeders in the other magazine,
partially used trays occur frequently.
• If parts resupply is not complete while the other magazine is being used in
production, production stops.
Job settings
1. At the [Machine Configuration - Modules] tab, select the [Stage Type] for the module
where the tray unit is located. Refer to "3.3.3 Configuring an NXT machine" for details.
2. Optimize the job. (Refer to "3.6 Optimizing" for details.)
3. Select the [Feeder Setup] tab and then check the tray allocation for magazines A and B.
4. If necessary, specify alternate trays. (Refer to "3.3.5 Assigning an alternate feeder" for
details.)
5. Send the job to the machine.

Mode 2: Producing with minimized downtime during parts resupply
Features
• The job is set up to produce while using each magazine separately. Up to 12
slots can be used (24 when using both subslots on the tray unit-LT).
• This mode minimizes downtime by allowing a magazine to continue production
when a recovery limit is reached at the other magazine. The magazine that
reached the recovery limit is then replenished with parts.
• Partially used trays occur easily because the magazine is exchanged at each
recovery limit.
Job settings
1. At the [Machine Configuration - Modules] tab, select the [Stage Type] for the module
where the tray unit is located. Refer to "3.3.3 Configuring an NXT machine" for details.
2. Optimize the job. (Refer to "3.6 Optimizing" for details.)
