As with automatic selection, if there is no disk larger than the minimum back light disk
specified in Part Data, vision processing cannot be carried out properly and a
transmission error will result (error code 1101D04?).
1.4.5 Determining the Nozzle Rotation Direction and Nozzle
Assignment Table
Using the current nozzle position as a reference, the next nozzle indexing direction
(clockwise or anticlockwise) is determined by which direction requires the least amount
of rotation. Data describing which size of nozzle is installed in which nozzle holder is
recorded in the nozzle assignment table.
Nozzle indexing is reduced to a minimum when all six nozzles in the holder (specified in
the NAT) are different (presuming the target nozzle is not skipped).
A “Next Nozzle” can be specified by having more than one of the same nozzle type in
the holder. If this is the case, when the nozzle is skipped the machine automatically
changes to a different nozzle of the same size and production continues. However,
unlike "Next Device", the next nozzle number cannot be specified.

1.4.6 Nozzle Type and Nozzle Holder Check
At Station 17 a set of three sensors will check to see which nozzle is being used in order
to determine whether or not nozzle change is necessary for the next part to be picked. At
Station 19, another set of three nozzle change check sensors will check to see if the
appropriate change has been made.
1.4.7 Nozzle Origin Search Sensor
On the machine, the nozzle is changed at ST18 when the nozzle holder clutch and the
spline shaft engage. In order for the nozzle holder clutch and the nozzle spline shaft to
engage, it is necessary that both centers are aligned. (If the nozzle center is not aligned
when nozzle origin position check is performed at ST15, that nozzle holder will be
skipped and parts will not be picked up.)

Part 2 Chapter 1 Basic Operation
Edition 1.1 2-1-38 CP643E System Reference
Nozzle Origin Search which occurs at ST12 checks the position of the nozzle holder and
the nozzle holder clutch to insure that nozzle changeover can be performed correctly at
ST18.
There are three instances when nozzle origin search is performed. One is after zero
setting following bootup, the second is before automatic operation (step operation
included), and the third is during automatic operation.
Nozzle origin searches (which occur after a zero-setting and before automatic operation)
consist of detecting all the origin position markers when the START button is pressed.
Nozzle origin search after zero-setting
Push START for zero-setting. Zero-setting and Origin searching is performed.
Nozzle origin search performed before automatic operation.
Push START (for automatic operation) Origin searching and automatic operation is
performed.
Nozzle origin search is performed
• before measuring the nozzle center
• after an emergency stop during automatic operation, where the cam has stopped
between the cam angles of 10° and 350°
• when turning the C-axis more than one cycle using the cam handle or using the
inching keys
Nozzle origin search during automatic operation
The machine performs origin search with the cam at an angle of 267° when the shaft
positioned at ST12, does not engage the ST12 FRQ clutch during automatic
operation.
