6.6 XY Table Height Adjustment
To reduce the stress put on parts during the placing process, there is a
vertical movement control system using a Z axis servo motor to match
part heights with the mounting surface. When reading block skip and
fiducial marks, the Z axis returns to its origin position. Also, when parts
are being rejected, if there are no table height settings, the Z axis lowers in
order to prevent parts that have been placed from interfering with parts
being rejected.
6.7 Parts Supply Position
If the machine stops during automatic or step operation for some reason
such as a part running out, then the position of the device table at which
parts will be resupplied must be determined at that time.
6.7.1 Joint Mode
If the part which has caused the alarm has been set at device
number 81 or above, then the device table will move up to a device
position 18 positions higher than the device number in question.
The device table will wait for parts to be supplied at that position.
If the part is set at device number 80 or below, then the device table
will move down by 18 device positions and wait there for parts to
be supplied.

6.7.2 Device Change Mode
If the part causing the alarm is set on device table 1, the table will
move to the right side (as viewed from the front of the machine) to
its resupply position.
If the part causing the alarm is set on device table 2, the table will
move to the left (as viewed from the front) to wait at its resupply
position.
However, if the recovery mode is set to Error Stop, there are 2 ways
of selecting the resupply position (based on settings made in Proper
data) so that the device table does not change.
The item in Proper data that must be set is 139: D ESC SW.
• If this Proper data item is set to YES then the device table will
move to its resupply position.
• If this item is set to NO then device table movement will be
much the same as it is in joint mode. In this case device number
40 is used to determine the supply position of the device table.
6.7.3 Changeover Mode
In Changeover mode there are two types of movement modes that
can be set in Proper data. The item in Proper data that must be set
is 139: D ESC SW.
• If this item is set to NO then device table movement will be
much the same as it is in joint mode.
If the part which has caused the alarm has been set at device
number 41 or above, then the device table will move up to a
device position 18 positions higher than the device number in
question. The device table will wait for parts to be supplied at
that position.
• If this Proper data item is set to YES then the device table in
question will move to its resupply position.
If device table 1 is used in automatic operation, the table will
move to the right (viewed from the front of the machine) to its
resupply position. If device table 2 is used it will move to the
left (front view perspective) and wait at its resupply position.

6.8 Discarding Picked Parts
On the FCP IV-3 data is managed for the picked parts that are at each
station. In the case that distribution of part information to each station
cannot be guaranteed, the picked parts will unavoidably have to be
discarded in order to preserve placement accuracy and reliability.
The discarding of picked parts will be carried out in the following cases.
• After an emergency stop
After the occurrence of an emergency stop the status of the parts that
have been picked and vision processed may not have been preserved.
If the cam axis is rotated manually (using the cam handle) the picked
parts will be discarded since there is a possibility that the information
for the processed parts is different from the actual status of the parts.
• After the cam axis has been inched
For the same reason as mentioned above, picked parts will be
discarded if the cam axis is rotated via inching since there is a
possibility that the information for the processed parts will be
different from the actual status of the parts.
• After the placing sequence order has been changed
If the number of the placing sequence or a block skip is specified by a
command operation, the picked parts will be judged as useless and
thus discarded since the placing sequence order will have changed.
• Execution of the nozzle center measurement command
Picked parts will be discarded when nozzle center measurement is
carried out since these parts are a hindrance to the execution of this
command.
