(2)Workpiece coordinate system for ordinary operation
(Master axis workpiece coordinate value)
= (parameter No. 1250 for the master axis)
+ (master axis machine coordinate value)
S If many slave axes are synchronized with one master axis, the master
axis is set with the workpiece coordinate system that corresponds to
the current position of the first slave axis that is synchronized with the
master axis.
S The same least command and input increments must be applied to both
master and slave axes.
S The tool offset is taken into consideration when the coordinate system
is set up. So, the coordinate system is set up normally even when tool
geometry compensation is applied.
S If synchronous control that involves automatic coordinate system
setting is started or terminated during automatic operation, a move
command or other commands that reference the current position of an
axis may not be specified in the current block and two blocks that
follow it (or three blocks for tool–nose radius compensation). An
exception is an M code in which the current block is not buffered. For
the M code, a move command can be executed in the block next to the
block that involves synchronous control.
[Classification] Input signal
[Function] These signals perform synchronous control.
[Operation] When one of these signals becomes “1”, the control unit:
S Starts synchronous control with the axis corresponding to this signal
used as the slave axis.
The axis with which the slave axis is synchronized is determined by
parameter No. 8180.
[Classification] Input signal
[Function] These signals place each axis in a parking state.
[Operation] When one of these signals becomes “1”, the control unit:
S Places the corresponding axis in a parking state.
If the corresponding axis is under synchronous control, it enters a parking
state immediately regardless of whether the axis is moving. If a parking
signal is set to “1” without specifying synchronous control, it is ignored.
