1. Overview
The input signal sent from the machine can switch the operation mode of two or more specified
axes: Synchronous, independent, or normal operation.
2. Details
2.1 Twin table control
When a machine has two tables that are independently driven with different control axes, the
following operation can be executed.
(1) Synchronous operation
This mode is used to machine a large workpiece that requires two tables at a time. When a
move command is specified for one of two axes, the other axis is synchronized with it. The
axis to which the move command can be specified is called the master axis. The axis which
is synchronized with the master axis is called the slave axis. When the Y-axis is used as
the master axis and the V-axis as the slave axis, the Y- and V-axes operate in
synchronization, as specified by command Yyyyy entered for the master axis.
The synchronous operation can be executed in automatic operation, continuous manual
feed, manual handle feed, and incremental feed. It can not be executed in manual return
to the reference position.
(2) Independent operation
This mode is used to machine a small workpiece on either of the two tables. The move
command specified for the master axis can determine the movement along the master or
slave axis.
(i) Command Yyyyy specified for the master axis determines the movement along the
Y-axis.
(ii) Command Yyyyy specified for the master axis determines the movement along the
V-axis.
The command specified for the master axis can be used even when only the slave
axis is operated. An identical command can be used, irrespective of the table on
which the workpiece is placed.
Independent operation can be executed in automatic operation. When it is executed in
manual operation, the resulting operation becomes the same as the normal operation
described below.

As in usual CNC operation, movements along the master and slave axes are specified by individual axis addresses, Y and V. The movements along the master and slave axes can be specified in an identical block.
