PROGRAMMING20. AXIS CONTROL FUNCTIONS
B–63534EN/02
578
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 The machine coordinates for the slave/dummy axis are
updated in synchronization mode.
With a G80.5 b 0 command, synchronization is canceled.
b is the address of the slave axis.
1. Canceling synchronization for each axis by issuing a command
Synchronization of the slave axis specified by ? is canceled.
A cancellation command can be issued only for one axis in one block.
When b 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.
2. Canceling synchronization by a reset
For an axis for which a parameter is set to allow synchronization to be
canceled by a reset, HBR, bit 0 of No. 7700, is set to 0, allowing
synchronization to be canceled by a reset. When a 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) P/S alarm No.000 (indicating that the power should be
turned off)
A command compatible with that for a hobbing machine can be used as
a synchronization command.
Such a command cannot be used when a canned–cycle option is provided.
Specify which axes starts synchronization with such a command by using
parameter No. 7710.
(1)Synchronization start
When the following command is specified, synchronization of spindle
axis and C axis starts
