1. AXIS CONTROL
205
NOTE
1 More than one axis can be subjected to synchronous,
composite, or superimposed control. On the other hand, an
axis cannot be synchronized with more than one axis
simultaneously. Moreover, an axis under composite control
cannot be synchronized with another axis or cannot doubly
be subjected to composite control.
2 Synchronous, composite, or superimposed control cannot
be performed between a linear axis and a rotation axis.
3 Synchronous, composite, or superimposed control cannot
be specified simultaneously with simplified synchronous
control. Synchronous control within one path provides the
same functions as simplified synchronous control.
CAUTION
1 The same acceleration/deceleration time constants and
servo parameters should be used for axes subjected to
synchronous control as much as possible. If there is a large
difference in a set value between the axes, a deviation will
occur in the actual movement of the machine.
2 The workpiece coordinate system of a synchronous slave
axis is not affected by the synchronous master axis
operations that affect workpiece coordinate systems but do
not cause the machine to move, such as workpiece
coordinate system set/shift and geometry offset
commands.
3 If a wear offset command or tool–nose radius compensation
is performed for the synchronous master axis, the travel
path of the slave axis is shifted by the offset, but the shift is
not set as an offset (no offset vector is created).
4 A move command should not be issued to a synchronous
slave axis during synchronous control.
