Definition of an axes configuration

With this NC command, a new axis configuration can be defined which replaces the existing axis configuration. This means, exactly the axes, which are programmed in NC command, form the new axes configuration of the NC channel.

#SET AX [<mode>] [<axis_name>,<axis_number><axis_index> {,<options>} ]
{ [<axis_name>,<axis_number><axis_index> {,<options>} ] } (non-modal)

<mode > With/without request for axis positions from the interpolator and a position initialization of the NC channel during the exchange of the axes.

Mode	Replacement of axis in the NC channel
	Default-setting: With request for set values from the interpolator and a position initialization of the NC channel.
FAST	Without request for set values from interpolator. Position initialization of the NC channel.

<axis_name > Permissible are strings with the starting characters A, B, C, Q, U, V, W, X, Y and Z. Multiple assigning of the same designation for different axes (identification through the logical axis number) causes an error message and an aborting of the NC-program.

<axis_number > The physical assignment of axes occurs via the logical axis number. Permissible are mathematical expressions. The logical axis number must be known in the axes management. During the request for an unknown logical axis number or several identical logical axis numbers an error message and an aborting of the NC-program will occur.

<axis_index >The axis index determines the location of the axis inside the axis group of the NC-channel. It defines thus the main and the synchronous axes (see the following table). Permissible are mathematical expression whose results are within the range [0 ... Maximum axes number -1]. The axis index must not yet be allocated with an axis. In case of a request to an index that is already allocated with another axis, an error message and an aborting of the NC-program will occur.

Index	Axes configuration
0	1. Main axis in the machining plane.
1	2. Main axis in the machining plane.
2	3. Main axis generally perpendicular to the machining plane.
3	1. Synchronous axis
...	...
n	(n-2). Synchronous axis.

<options> Offsets are axis-specifically maintained. The following are involved here:

Reference point offset,
Machine table offset,
Tool offset,
Zero offset,
Measurement offset,
manual operation offset,
Preset offset,

With the key words from the following table the inclusion of offsets can be controlled during the request for axes.

Key word	Exchange of axis
	No inclusion of offsets (default)
ALL	Inclusion of all offsets *
BPV	Inclusion of reference point offset
PZV	Inclusion of machine table offset
WZV	Inclusion of tool offset *
NPV	Inclusion of zero offset
MOFFS	Inclusion of measurement offset
SOFFS	Inclusion of manual operation offset
PSET	Inclusion of preset offset

Notice

*When the tool is selected, pay attention to the following when adopting tool offsets in the case of #SET AX:
If axes are only swapped (internal axis replacement) by #SET AX and otherwise no additional axes are specified or requested, all offsets (including the tool offsets) are also replaced and continue to remain active. Specifying key words to adopt offsets has no effect. If a new tool is then selected, the offsets also replaced are replaced by the new tool's offsets.
As soon as an axis release or an axis request is triggered by #SET AX (external axis replacement), the tool offsets are included again in calculation of the sequence of axes indexed in the tool data. Therefore, any adopted tool offsets are replaced by the current tool's offsets! If the original tool offsets in the corresponding axes are to continue to apply, a new tool must be selected in the case of which the offsets have been adapted to the new axis arrangement.
You are therefore advised to run #SET AX with the tool deselected and to ensure the correct assignment of tool offsets by the appropriate parameterization in the record of a newly selected tool.

CAUTION

Example:

Index of tool offsets in tool data	[0]	[1]	[2]	[3]
Parametrized tool offsets e.g. for T1	50	0	70	20
Axis configuration on program start	X	Y	Z	---
Included tool offsets after T1 selection	50	0	70	---
"Internal" #SET AX {Z, X, Y}:	Z	X	Y	---
Tool offsets are also swapped or	70	50	0	---
"External" #SET AX {Z, X, Y, B}:	Z	X	Y	B
Tool offsets are newly recalculated corresponding to T1	50	0	70	20

Example:

Assignment of axis names, logical axis numbers and axis indices at the time of program start:

Axis name	Logical axis number	Axis index
X	1	0
Y	2	1
Z	3	2

Programming example

(Setting of axis configuration:
(X-axis remains in its place;)
(Y-axis is released;)
(Z-axis is resorted acc. to Index 4;)
(Y1- and Z1-axis are requested)
%ACHSTAUSCH1
N10 #SET AX [X,1,0][Y1,4,2][Z1,5,3][Z,3,4]

Assignment of axis name , logical axis numbers and axis indices after N10:

Axis name	Logical axis number	Axis index
X	1	0
		1
Y1	4	2
Z1	5	3
Z	3	4
