Chapter 5 Next DevicePart 2
Part data: Carrying data
20. D_change_trigger
• Error: The device or device table will change
when the device is out of parts, not picking
properly or experiencing a vision
processing error.
• Parts: The device or device table will change only
when the current device is out of parts.
• Miss: The device or device table will change only
when the device is out of parts or not
picking properly.
5.2 Next Device Operation
Herein is an explanation of how the Next Device function operates.
(1) In the production program, a device number (D) from which parts are
to be picked is set in Sequence data. This is the original device.
(2) When the original device is out of parts, it will change to the device
number set in “Next” of Device data (D_data).
(3) After that, when parts run out again, if the number in “Next” is not
the original device, it will go to that device.
(4) If the number specified in "Next" is not the original device and there
are no parts on this feeder, and if the final next device is out of parts,
automatic operation will be interrupted.
Note: For further information on the Next Device function refer to the
MCS/2H Operation Manual.
5.3 Points to Remember When Using Next Device
In the production information the next device is not considered. Parts
picked from all original devices are totalled.
When setting next devices a loop must be set. This loop can use up to 30
devices.
When next devices have been set, the time required per cycle increases.

FCP IV-3 Operation
Chapter 6 Nozzle Statistical ProcessingPart 2
6. Nozzle Statistical Processing
The FCP IV-3 has a statistical processing function which monitors the number
of nozzle errors that occur, and automatically skips any nozzle that generates
errors frequently. This statistical processing function is called the nozzle skip
function.
6.1 Nozzle Skip Method
Nozzle skip can be set in Proper data. This function is effective for
detecting dirtied nozzles, or when there are too many rejected parts.
Nozzle skip can also be set manually, as described previously in this
manual. This is useful when there are dirty nozzles that the operator
already knows about.
6.2 Setting Nozzle Skip
If a nozzle becomes damaged during automatic operation so that it can no
longer be used, the nozzle can be automatically skipped without having
to interrupt production. This function is referred to as the nozzle skip
function.
6.2.1 Auto-skip
When there is a nozzle error (i.e. a picking error or vision
processing error), that nozzle will be declared inoperative and the
nozzle number will appear on the display monitor. In operation,
the total number of small, medium and large nozzles that are
defective, each have a limit below which the machine continues to
operate. The defective status of a nozzle can be cancelled manually
using the procedure described below.
6.2.2 Manual Nozzle Skip
Pressing the [SET], [MANUAL] and [NOZZLE SKIP] command
function keys in that order will either set or cancel the nozzle skip,
depending on the context of the situation. If, however, the nozzle
skip has been set manually it must be cancelled manually as well
and cannot be used again.
