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.

1.7 Device Check

When parts are replenished or changeover takes place, devices that have been set can be

verified one by one on the display in order to prevent parts from being mounted

incorrectly. This function is referred to as device check. It is also possible to set this

function such that operation does not begin again until every device has been checked.

1.7.1 Method and Function

There are two methods of carrying out the device check function. Device check can be

performed on the machine using the command keys, or it can be done with the use of the

PARTS SET COMPLETE switch.

Performing Device Check on the Machine

The device check function can be made mandatory with the commencement of automatic

operation or it can be carried out as a command key operation. When device check is to

be made mandatory with the start of automatic operation, the Proper data item 70:

Device Check SW must be set to either "Parts", "Miss", or "Error". When device check is

carried out as a command operation, setting values in Proper data is not necessary.

When a mandatory device check is carried out with the start of automatic operation,

device check is carried out in accordance with the setting made in Proper data item 70:

Device Check SW. Furthermore, anytime the production program is changed, device

check is carried out when automatic operation begins again. Operation is not possible

until the device check is completed.

To perform device check at the machine, press the following command keys:

[Program] – [Device] – [Check]

Note: For information concerning the commands refer to Part 3, "Commands".

PARTS SET COMPLETE switch

The PARTS SET COMPLETE switch is used as a final check switch once the parts set

operation is complete. When this switch is set to "COMPLETE" production becomes

possible and the resupplied device table will move to its part picking position.

On the other hand, if for some reason the device table in the resupply position is not to

be moved to its part picking position even though the parts set operation is complete,

then this switch can be set to "CANCEL" to prevent the table from being used in

production.

This switch is only enabled when the device table is in its resupply position. This

function does not work when the device table designated as the original table is in its

part picking position.

This switch works differently depending on whether the device check function is used or

not. This difference is explained below.

1. When the device check function is not used

In this case production becomes possible with the device table in question when the

switch is set to "COMPLETE." The signal tower on the rear fence will begin flashing.

On the other hand, if the switch is set to "CANCEL" then production with the device

table in question will not be possible. The signal tower on the rear fence will be lit.

2. When the device check function is used

In this case when all devices have been checked and the switch is set to "COMPLETE",

production becomes possible and the device table moves from its resupply position to

its part picking position.

If the switch is set to "CANCEL" the machine remains in device check mode and

production with that table is not possible. The signal tower on the rear fence will be

lit.

To operate in the device change mode the status of one of the tables, either table 1 or

table 2, must be ready for production.

Also note that to operate in the changeover mode it is necessary for the original table to

be ready for production.

In the case where operation is not possible because neither table is ready for production,

the message "Parts are unset" will display and the machine will wait for the PARTS SET

COMPLETE switch to be set to "COMPLETE".
