1 TWIN-TABLE CONTROL
1.1 Overview
In twin-table control, synchronization operation, single operation, and normal operation can
be switched for two or more specified axes by a signal input from the machine side.
The following operations can be performed for a machine tool having two tables, each of
which is independently driven by a separate controlled axis.
-Synchronization operation : According to a move command issued to one axis, the other
axis can be operated in synchronization.
- Single operation : With the use of a move command for the master axis, movement for
the master axis alone or for the slave axis alone can be performed.
- Normal operation : In the same way as in normal CNC control, specify respective axis
addresses for movement for the master axis and for the slave axis.
In synchronization operation, an axis for which a move command can be issued is called
the master axis, and an axis for which movement is performed in synchronization with that
for the master axis is called a slave axis.
