MACHINE PARAMETERS.
(REF: 1402)
General machine parameters. Execution channels.
GEOCONFIG
Geometrical configuration of the axes of the channel.
Possible values: Plane / Trihedron.
Default value: Trihedron.
Associated variable: (V.)[ch].MPG.GEOCONFIG
Not being used at the mill model. On the lathe model, this parameter indicates the axis
configuration of the machine, trihedron or plane.
Configuration of "Trihedron" type axes.
This configuration has three axes forming a Cartesian XYZ type trihedron like on a milling
machine. There may be more axes, besides those forming the trihedron; that may be part
of the thihedron or be auxiliary axes, rotary axes, etc.
With this configuration, the planes behave in the same way as on a milling machine except
that the usual work plane will be G18 (if it has been configured like that in parameter IPLANE).
The order of the axes in the channel sets the main work planes, those selected with functions
G17, G18 and G19. Function G20 may be used to form any work plane with the axes of the
channel.
The CNC displays the ·G· functions associated with the work planes.
Configuration of "plane" type axes.
This configuration has two axes forming the usual work plane on a lathe. There may be more
axes, but they cannot be part of the trihedron; there must be auxiliary, rotary, etc.
With this configuration, the work plane is always G18 and will be formed by the first two axes
defined in the channel. If the X (firs axis of the channel) and Z (second axis of the channel)
have been defined, the work plane will be the ZX (Z as abscissa and X as ordinate).
The work plane is always G18; machine parameter IPLANE is not applied and it is not
possible to change planes via part-program. The ·G· functions associated with the work
planes have the following effects.
The CNC does not display the ·G· functions associated with the work planes because it is
always the same plane.
Configuration of "plane" type axes. Configuration of trihedron type axes.
Plane. Abscissa axis. Ordinate axis. Longitudinal axis.

Function. Meaning.
G17 It does not change planes and shows a warning about it.
G18 It has no effect (except when function G20 is active).
G19 It does not change planes and shows a warning about it.
G20 It is permitted if it does not change the main plane; i.e. it can only be used to change
the longitudinal axis.
