Note
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.
7 Pitch error compensation and backlash compensation are applied to
the master axis and slave axis independently.
8 Synchronous control selection signals SYNC1, SYNC2, SYNC3, ... can
be switched from the PMC side by the use of an M function of a
program command. In this case, specify an M code to be used in
parameters Nos. 7633, 7634 and 7642, which are for the M code used
for switching synchronous control and twin table control.
9 A single operation cannot be applied when the machine is operated
manually.
To operate the machine manually, use a synchronization operation or
normal operation.
