NOTE
1 In synchronization operation, reference position
return movement for the Y axis is also applied to the
V axis for an automatic reference position return
command (G28) and the second, third, and fourth
reference position return commands (G30). After
the return movement, when the tool is positioned to
the reference position along the V axis, a reference
position return completion signal for the V axis goes
on in the same way as for that for the Y axis.
In principle, specify the G28 and G30 commands for
normal operation.
2 In synchronization operation, the same movement is
performed along the Y and V axes for an automatic
reference position return check command (G27).
After the movement, when the tool reaches the
reference positions along the Y and V axes, the
respective reference position return completion
signals go on. If it is not located at the reference
positions, an alarm is indicated. In principle, specify
the G27 command for normal operation.
3 To specify the G28, G30, or G27 command, manual
reference position return must have been performed
after power on.
4 A command with no movement along an axis, such
as the workpiece coordinate system setting
command (G92) and the local coordinate system
setting command (G52), is applied to the master
axis in synchronization operation and the command
is applied to the slave axis in slave-axis single
operation by the use of a program command for the
master axis.
5 Perform manual reference position return in normal
operation.
6 Signals, such as an external deceleration signal, an
interlock signal, and a machine lock signal, are
effective only for the slave axis in slave-axis single
operation and are effective only for the master axis
in synchronization operation. The signals for the
other side in each case are ignored.
