1.1.3 Changing the Original Table
The original device table, the table which is used first, is selected automatically when a
new production program or table mode is selected. The conditions under which the
original table will change are listed below.
(1) Change Due to Change of Production Program
The original table is determined according to the table mode when the new production
program is selected. On-screen display content is shown in parentheses.
• Device Change Mode (2A1A) and Changeover Mode (2B1A/2A1B)
The original table changes depending on the setting in the production program as
explained below.
<For MCS>
[Program] Machine_data, 37. Original_table (Non, Table1, Table2)
Non: The table other than the table used until now is the original table. If table 1
had been used, table 2 will be the original table, and vice versa.
Table1: When the program has been changed and foreground transmission has been
carried out table 1 will be the original table.
Table2: When the program has been changed and foreground transmission has been
carried out table 2 will be the original table.
When Original_table is specified and many programs have used the same devices, then
time can be saved by not having to change feeder positions, or use commands to change
the original table.
<For F4G>
Selected at the Table_Mode section of the “CCIMF Generate” item which displays when
programs are transmitted to the machine.
• Joint Mode (JOINT)
There is no original table.

(2) Change Due to Change of Table Mode
• When changing from joint mode to changeover or device change mode, table 1 will
automatically become the original table. If the original table is specified in the
program, that table will be used when changing to device change mode.
• When switching from changeover mode or device change mode to joint mode, there
will be no original table.
• When switching from changeover mode to device change mode, the original table will
remain the same.
Every time the operations described in (1) and (2) above are dealt with, the original table
is changed and it is shown at the display. Press [SET], [STATUS] and [TABLE MODE] to
reach command Page 513/000 to change the original table if the selected original table is
different from the actual table to be used.
1.1.4 Device Tables: Part Pick-up Position and Resupply Position
There are two separate device tables each with 70 for CP-643E (50 for CP-643ME) device
positions. Each table can be resupplied at its respective resupply position.
There are 3 possible table modes that can be set to determine how the device table is to
be used. During operation the device table will move automatically to either its part
pick-up position or to its resupply position depending on the following conditions.
(1) Conditions for Moving to the Part Pick-up Position
The appropriate device table will move to its part pick-up 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 spare table is in parts set complete status.
• During production in device change mode, when the original table is changed to the
spare table in the resupply position which is in parts set complete status.
• 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 [POSITION] commands.

(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 pick-up
position is not the original table.
• During production in device change mode, when the original table in the part pick-up
position runs out of parts.
• When [D RESUPPLY] command is used to move the device table to the resupply
position.
(3) Shutter Operation
The appropriate shutter will open prior to the movement of the respective device table.
At any other time, the shutters will remain closed.
1.1.5 XY-Table Height Adjustment
In order to reduce the increased stress that is exerted on parts during placement, the
placement surface is aligned with the height given in part data by means of up and down
control of table movement via a Z-axis servo.
Note: On the CP-643E since the board clamp reference surface is the lower surface, which has
been the upper surface for CP-6/642, it is necessary to enter the PCB thickness item in
production program.
The Z-axis height during the placing operation thus becomes “Z0 - PCB thickness - part
height”.
When a block skip mark or fiducial mark is read or when board check is carried out, it is
done at the position defined by “Z0 - PCB thickness - 5.0 mm”.
Furthermore if a part is rejected, the Z-axis descends unconditionally in order to avoid
interference between parts that have been placed on the board and the part being rejected.
