• 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.

Insertion of Recovery Sequence

If a vision processing error occurs or there are no parts and the machine is set to carry

out a recovery operation, the recovery sequence will be inserted either 6 or 15 sequences

later.

If an error occurs between station 17 ~ 2 then recovery processing takes place at station 2

(this is done 6 sequences later however, this recovery processing does not include such

things as parts being discarded due to an emergency stop).

When an error occurs between station 3 ~ 10, recovery processing for such things as the

discarding of parts due to an emergency stop takes place at station 11 (15 sequences

later).

1.4 Nozzle Related Functions

1.4.1 Nozzle Check Function

This function checks the production program to confirm that the appropriate nozzle is

installed in each holder. This is done by performing a check on the nozzle diameter and

the back light disk size.

If a program has been transmitted to the foreground, then once program changeover has

been completed the Nozzle Check function is carried out when automatic operation

begins. If the nozzles installed in the previous production program have the same nozzle

diameter and back light disk size as the nozzles set to be used in the current production

program then no check is performed. If either the nozzle diameter or the back light disk

size are different then a check is performed. A check does not occur, for example, if a

white nozzle is replaced with a black nozzle, regardless of the nozzle size, etc.

It is necessary to set the appropriate Proper data item to enable this function. Make the

setting in the following manner:

[Proper]

136. Nozzle Check SW: This Proper data item determines whether or not the function

will be carried out.

(Example) 136. Nozzle Check SW Yes No

Yes: Mandatory nozzle check occurs

No: Mandatory nozzle check does not occur

When the Nozzle Check function is enabled a display like the one below will appear.

SET: Press this key to set the selected nozzle.

▲: Press this key to move the cursor up.

▼: Press this key to move the cursor down.

RETURN: Press this key to enter the nozzle center of rotation measurement command.

"UNSET" is displayed in red and "SET" is displayed in green.
