Master–axis travel Slave–axis travel
Specify the master–axis travel in either of the fol-
lowing ways.
1. Master–axis speed
T t : Master–axis speed (1 v t v 1000)
2. Master–axis pulse count
P p : Master–axis pulse count
(1 v p v 999999999)
Specify a pulse count on the condition that
four pulses correspond to one period in
the A and B phases.
Specify the slave–axis travel in either of the follow-
ing ways.
1. Slave–axis travel
bj b : 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
b 0 L"l b : Slave–axis address
l : Slave axis speed
(1 v l v 21)
G80.5 b0 ; Ends synchronization.
b:Slave axis address
Note) The start/end of synchronization cannot
be specified for two slave axes with a
single command.
f
G90_; Absolute command
G91_; Incremental command
G90_G91_; Change of workpiece coordinate system
Note) With the T series, these commands are appli-
cable when G code system B/C is used.
When G code system A is used, a distinction
between absolute and incremental com-
mands is made by address specification as
follows:
X_ Z_ C_ : Absolute command
U_ W_ H_ : Incremental command
f f
G92 _ ; Change of workpiece coordinate system
G92 S_ ; Constant surface speed control
Setting of maximum spindle speed
