This operating mode is used for machining different workpieces on each
table. The operation is the same as in ordinary CNC control, where the
movement of the master axis and slave axis is controlled by the
independent axis address (Y and V). It is possible to issue the move
commands to both the master axis and slave axis in the same block.
(1) The Y axis moves normally according to program command Yyyyy
issued to the master axis.
(2) The V axis moves normally according to program command Vvvvv
issued to the slave axis.
(3) The Y axis and the V axis move simultaneously according to program
command YyyyyVvvvv.
Both automatic and manual operations are the same as in ordinary
CNC control.
For how to switch between the synchronous operation and normal
operation modes, refer to the relevant manual published by the machine
tool builder.
When the automatic reference position return command (G28) and the
2nd/3rd reference position return command (G30) are issued during
synchronous operation, the V axis follows the same movement as the Y
axis returns to the reference position. If the V axis is or is not positioned
at the reference position after the return movement is complete, the
reference position return complete signal of the V axis goes on when that
of the Y axis goes on.
As a rule, commands G28 and G30 must be issued in the normal operating
mode.
NOTE
P/S alarm No.213 is issued if automatic reference position
return operation is specified without performing manual
reference position return operation after power–on.
When the automatic reference position return check command (G27) is
issued during synchronous operation, the V axis and Y axis move in
tandem. If the reference position along the Y–axis is reached upon
completion of travel, the reference position return completion lamp is
turned on for both of the Y–axis and V–axis, regardless of the position
reached along the V–axis. If either Y–axis is not at the reference position,
an alarm is issued. As a rule, command G27 must be issued in the normal
operating mode.
When a move command is issued to the slave axis during synchronous
operation, a P/S alarm (No.213) is issued.
The axis to be used as the master axis is set in parameter No.8311.
The slave axis is selected by an external signal.
Setting bit 7 (SMF) of parameter No.3105 to 1 suppresses display of the
actual speed of the slave axes.
