NOTE
1 During synchronization, manual handle interruption
can be performed on the slave and other axes.
2 The maximum feedrates on the master and slave
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 G81.5 is issued again during synchronization,
alarm PS1595 is generated if ECN, bit 3 of
parameter No. 7731, is 0. If ECN, bit 3 of
parameter No. 7731, is 1, the synchronization
coefficient can be changed to a newly specified one.
6 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.
7 In EGB synchronization mode, AI contour control
mode is temporarily canceled.
- Synchronization end
1 Canceling synchronization for each axis by issuing a command
With a G80.5 β0 command, synchronization is canceled.
β is the address of the slave axis. Synchronization of the slave
axis specified by β is canceled.
A cancellation command can be issued only for one axis in one
block.
When β0 is not specified, the synchronization of all currently
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.
2 Canceling synchronization by a reset
By setting HBR, bit 0 of parameter No. 7700, to 0,
synchronization is canceled with a reset. If the manual absolute
signal is ON, the absolute coordinates are updated.
3 Others
Synchronization is automatically canceled under the following
conditions.
<1> Emergency stop
<2> Servo alarm
<3> A slave axis overtravel (software, hardware) alarm is
generated
