G180 Modal travel "on"

Traverse one or several axes modally with the programmed speed in the
specified direction.

G180 AXES F

AXES

Axes to be traveled. The programmed value specifies the traversing
direction.
> 0: positive traversing direction,
< 0: negative traversing direction,
= 0: only preselect speed.

F

Modal traversing speed.

With G180, axes can be traversed modally in the specified direction, until the
traversing function is deactivated again with G181. The further execution of
the program is not blocked during this process, so that other axes can also be
traversed in the program in parallel.

If several axes are programmed in a G180, the acceleration ramp of the
individual axes is reduced such that all axes reach their programmed speed
at the same time. If a traversing direction is specified and the axis is already
modally traversed, the axis is accelerated to the new speed and direction
without stopping.

If a feed speed F is programmed, this applies to all the axes programmed in
the same block. However, if linear and rotation axes are involved, it only
applies to the linear axes. Preselecting a speed for one or several axes,
without starting them, is carried out by selecting the "Verfahrrichtung 0"
(traversing direction 0).

Modal travel axes cannot be positioned with geometry functions. They are
stopped by G181, the stop button and by errors of class 3 and 4.

N10 G180 X0 F1000

Preselect 1000 mm/min as the modal speed for X

N20 G180 A0 B0 F20

Preselect 20 U/min as the modal speed for A and B

N30 G180 X1 A1 B−1

Traverse X, A and B modally. X in positive direction with 1000
mm/min, A positive with 20 U/min and B negative with 20
U/min.

N40 G180 Y−1 F2000

Traverse Y with 2000 mm/min modally in negative direction

...

N80 G181 X0 Y0

X and Y stop, A and B continue.

N90 G181

stop all axes started with G180
