- 247 -
βj : Slave-axis address
j :Slave-axis travel indicated in units of the minimum
travel increments (the range of valid settings for usual
axis movement applies)
When j = 0, the specified command is regarded as being
a command for the slave-axis speed, described below.
In this case, if L is not specified, an alarm is output.
2. Slave-axis speed
β0 L
±l : β :Slave-axis address
l :Slave axis speed (1≤ l ≤21)
CAUTION
1 A move command can be issued by a program to the
slave axis or other axes during synchronization. In
this case, the command shall be an incremental
command.
2 A G27, G28, G29, G30, G30.1, G33, or G53
command cannot be issued to the slave axis in
synchronization mode.
3 Controlled-axis removal cannot be used for the
master axis or the slave axis.
NOTE
1 A manual handle interruption can be issued to the
slave axis or other axes during synchronization.
2 The maximum feedrates for the master axis and the
slave axis are limited according to the position
detectors used.
3 An inch/metric conversion command (G20 or G21)
cannot be specified in synchronization mode.
4 Only the machine coordinates for the slave axis are
updated in synchronization mode.
- Synchronization end
1. Canceling synchronization for each axis by issuing a command
With a G80.5 0 command, synchronization is canceled.
is the address of the slave axis. Synchronization of the slave axis
specified by is canceled.
A cancellation command can be issued only for one axis in one
block.
When 0 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.
