6.3 Changing the Original Table

The original device table (that is, 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.

6.3.1 Change Due to Change of Production Program

The original table is determined according to the table mode when

the new production program is selected, as follows:

• Changeover mode (1A 2B)

The original table changes depending on the setting in

Original_table in Machine data, as explained below.

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 parts must be replaced and the

original table specified manually.

• Device Change Mode (1A 2A)

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.

• Joint Mode (JOINT)

There is no original table.

6.3.2 Change Due to Change of Table Mode

• When changing from joint mode to changeover mode, or to

device change mode, table 1 will automatically become the

original table. Note that if the original table is specified in the

program in device changeover mode, that table will be used.

• When changing from changeover mode or device change mode

to joint mode, there will be no original table.

• When changing from changeover mode to device change mode

the original table will remain the same.

When dealing with the operations described in 7.3.1 and 7.3.2, the

next original table number will be displayed. Press [SET],

[STATUS] and [TABLE MODE] to reach command Page 514/000 to

set the original table.

6.4 Device Tables: Part Pickup Position and Resupply Position

There are 2 separate device tables each with 80 device positions. Each

table can be resupplied at its respective resupply position.

If only one device table is used for production, parts for a different

program can be set on the other device table by moving this device table

to its 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 pickup position or to its resupply position

depending on the following conditions.

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.
