Part 1
6.4.1 Conditions for Moving to the Part Pickup Position
The appropriate device table will move to its part pickup position
under any of the following conditions.
• During production in joint mode, when the device table to be
used in the program is at its resupply position.
• During production in device change mode, when the original
table is out of parts and the parts set operation is complete on
the spare table.
• During production in device change mode, when the original
table is changed to the spare table in the resupply position on
which the parts set operation is completed.
• During production in changeover mode, when the table that
has been resupplied is set as the original table.
• When the device number is specified using manual commands.
6.4.2 Conditions for Moving to the Resupply Position
The appropriate device table will move to its resupply position
under any of the following conditions.
• During production in changeover mode, when the device table
in the part pickup position is not the original table.
• During production in device change mode, when the original
table in the part pickup position runs out of parts.
• When manual commands are used to move the device table to
the resupply position.
6.5 Shutter Operation
The appropriate shutter will open prior to the movement of the respective
device axis. At any other time the shutters will remain closed.

Part 1
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.
