Coordinate Rotation Using Measured Results(G168); Absolute Command And Incremental Command (G90, G91) - Brother TC-32B Manual

Chapter 3 Preparation Function
3.20 Coordinate rotation using measured results
(G168)
Command format
The coordinate system commanded in the absolute value is always recognized.
When this setting is omitted, the position in which the block has shifted from G69 to G168 (or
3
G68) is considered the center.
The coordinate is rotated using the angle obtained from the measurement.
Other features are the same as those for the coordinate rotation function.
3.21 Absolute command and incremental
command (G90, G91)
The axis movement amount can be specified by either the absolute command or the
incremental command.
(1) Absolute command (G90)
This is commanded by the G90 code. It specifies an end point of the block in the working
coordinate system.
(2) Incremental command (G91)
This is commanded by the G91 code. It specifies a distance from the start point to the end point in
the block.

G168 X_Y_Q_;
X,Y : Rotation center coordinate value.
Q : Selects the desired measured result by setting "1"
to "4".
When the selection is omitted, the setting is
considered to be "1".
