Device Change Mode Tables 1 and 2 are used separately. A maximum of 70 devices is possible on each table. Either table 1 or 2 can be used, and the table not in use is referred to as the spare table. This mode can be used…

Production Modes

Product: This mode is used for producing boards. Parts are picked up, parts inspection

is performed and the parts are placed on the boards.

Simulate: This mode is used for such purposes as verifying placing coordinates. Parts

are not picked up. The XY-table and the device tables operate as they do during

production.

Idle: This mode is used for such purposes as machine adjustment, testing or machine

warm-up. Continuous operation is performed without changing the board or

performing vision processing. The placing heads descend at stations 1 and 11. The

carrier operation is not performed. When using this mode, the feeders should be

removed from the device tables.

Idle 2: This mode is also used for such purposes as machine adjustment, testing or

machine warm-up. In addition to the Idle operation, the carrier operation is performed.

When using this mode, the feeders should be removed from the device tables.

Command Pass: [AUTO] or [STEP] - [MODE] - Select [PRODUCT], [SIMULATE], [IDLE]

or [IDLE 2]

Pass: This mode is used when the machine is not used in current production. The

machine simply acts as a board conveyor, moving the board on to the next machine in

the line.

Pass Mode

The two ways of carrying out Pass mode are described below.

• Set Production_mode in the program to Pass.

• Select the command sequence [SET] – [STATUS] – [PASS].

If Pass mode was set in Production_mode in the program then the message “Pass” will

display in yellow at the machine. If Pass mode was set using the command keys at the

machine then the message "Pass" will display in blue (at the machine).

1.3.3 Setting the Device Table Mode

On the machine there are three device table modes: joint mode, device change mode and

changeover mode. An explanation of each mode follows.

Joint Mode

Tables 1 and 2 move synchronously as one large table capable of handling up to 140

devices.

This mode is used in programs with a large number of parts.

The device table from which parts are being picked is referred to as the "production

table" while the table from which parts are not being picked is called the "follow-up

table".

Device Change Mode

Tables 1 and 2 are used separately. A maximum of 70 devices is possible on each table.

Either table 1 or 2 can be used, and the table not in use is referred to as the spare table.

This mode can be used to eliminate down time on the production line.

Changeover Mode

Tables 1 and 2 are used separately. A maximum of 70 devices is possible on each table.

Either table 1 or 2 can be used and the other table can be prepared for use with the next

production program.

When the program is changed the next device table moves to its part picking position.

The table used until now moves to its resupply position.

This is useful for when the operator has many small production runs.

Command Pass: [SET] - [STATUS] - [T MODE] - [CHANGE]

Note: For Device Change and Changeover modes, press [TABLE1] or [TABLE 2] to select the

production table.

1.3.4 Parts Error Handling

When a part cannot be picked, or when a part is judged to be defective, the same type of

part is picked again at the next opportunity. This is called recovery. Recovery mode can

be set in host computer status data or at the machine by pressing [SET], [STATUS],

[RECOVERY] and [CHANGE]. There are three types of recovery modes: auto recovery,

error stop and error pass, each of which are explained below.

Auto Recovery

If a part is rejected during inspection or if the part is not picked, the device number is

recorded in the error recovery counter, and the recovery operation is automatically

carried out. When the error recovery counter exceeds a preset number, the machine

stops. The error recovery counter number can be set either through host computer or by

pressing: [SET], [STATUS], [RECOVERY] and [TIMES].

[Example] If the counter is set at two, the machine will stop when a part at the same

device number is mispicked three times.

• Error Recovery Counter

Each device number is registered in the counter, and every error is registered and

sorted by device number. Each error increases the counter by one. If a part is

determined as good this counter is cleared. However, when the number of part errors

or missing parts for any given device number reaches a preset number the machine

stops.

• After a Recovery Limit Error

After the error recovery counter reaches its preset number the machine stops when the

head with the defective part reaches station 8. In this case, it is likely that sequences

for the same part have been allocated to other heads (between station 1 and 7) which

will also cause an error. To ensure the same error does not recur for part which has be

resupplied (when the machine is restarted), the error count is ignored for these parts.

• Next Device

If the error recovery counter reaches its preset number and a next device has been

specified, the next device will be used to supply parts. For detailed information

related to the next device function refer to section 1.20 “Next Device” of this chapter.

• Device Change Mode

When the error recovery counter reaches its preset number while operating in device

change mode, the other table will be used if parts have been set. For detailed

information refer to sub-section 1.3.3 “Setting the Device Table Mode” of this chapter.

• Large Parts Pick-up Check

At Station 2 the machine can check whether or not large parts have been picked. If the

results of this check indicate that a part has not been picked, the machine immediately

stops. In this case the machine stops after the first missing part is detected without

regard to the number of recovery times. Recovery is carried out when the machine is

restarted.

• Clearing the Counters After Program Change

In device change mode and joint mode, all the device number counters will be cleared.

In changeover mode, only the table which has been set as the original table will be

cleared.

Error Stop

In this mode, when parts out or an error is detected the machine will stop every time.

After the START button is pressed, a recovery operation will be carried out. Even when

operating in device change mode or when using the next device function, device change

is not carried out and the detection of an error or of parts out will halt operation.

Error Pass

In this mode, when parts out or an error is detected the machine will not stop. A

recovery operation will not be carried out. Even when operating in device change mode

or when using the next device function, device change is not carried out and operation

continues.
