NOTE
1 During synchronization, manual handle interruption
can be performed on the workpiece and other
axes.
2 The maximum feedrates on the tool and workpiece
axes are restricted by the position detector used.
3 In synchronization mode, no inch/metric conversion
commands (G20 and G21) cannot be issued.
4 In synchronization mode, only the machine
coordinate on the slave axis is updated.
5 If EFX, bit 0 of parameter No. 7731, is 0, the
canned cycle for drilling cannot be used. To use
the canned cycle for drilling, set EFX, bit 0 of
parameter No. 7731, to 1 and use G81.8 instead of
G81 and G80.8 instead of G80.
6 If TDP, bit 0 of parameter No. 7702, is 1, the
permissible range of T is 0.1 to 100 (1/10 of the
specified value).
7 If, at the start of EGB synchronization (G81), L is
specified as 0, synchronization starts with L
assumed to be 1 if LZR, bit 3 of parameter
No.7701, is 0; if LZR, bit 3 of parameter No.7701,
is 1, synchronization is not started with L assumed
to be 0. At this time, helical gear compensation is
performed.
8 Feed per revolution is performed on the feedback
pulses on the spindle. By setting ERV, bit 0 of
parameter No. 7703, to 1, feed per revolution can
be performed based on the speed on the
synchronous slave axis.
9 In EGB synchronization mode, AI contour control
mode is temporarily canceled.
- Synchronization end
Synchronization of all synchronized axes is canceled.
When a synchronization cancellation command is issued, the absolute
coordinates for the slave axis are updated according to the amount of
travel during synchronization.
For a rotation axis, the value obtained by rounding off the amount of
travel during synchronization to the nearest 360 degrees is added to
the absolute coordinates.
In a G80 block, do not specify addresses other than O or N.
