Programming of Traversing Blocks 04.97
4.9.3 Tracking synchronism (G79)
In tracking synchronism G79, the slave axes are moved to the position of the master axis. G79
is effective block by block.
Programming:
N10 G01 G79 X(Y)1234.000 F1000.00
N20 X(Y)2000.000
N10: If the Y-axis (slave axis) is not in the same position as the master axis, the Y axis will
be traversed at speed F1000.000 to the position of the master axis. The position
value X(Y)1234.000 only serves for selecting the axis/axes. If the Y-axis is already in
the position of the master axis, N10 will be ignored.
N20: The synchronous axes X and Z are traversed together to X(Y)2000.000.
Synchronism monitoring must only be switched on when the axes have
been synchronized.
