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.

# AX DEF <mode>] [NAM, NBR, IDX] [<axis_exchange_sequence> {,<options>} ]
{ [<axis_exchange_sequence > {,<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.

NAM, NBR, IDX Logic switches for the handling of conflicts.

The logic switches can be programmed individual or in combination!

<axis_exchange_sequence> consisting of:

<Axisname> For the axis name strings with the following initial letters are allowed: A, B, C, Q, U, V, W, X, Y and Z.

With conflicts within the programmed axis exchange sequence: Redundant axes names -> ERROR, Abort of NC program With conflicts to already existing axes in NC channel: Axes names identical, Axes numbers different -> ERROR, Abort of NC program With active logic switch NAM the conflict is solved as follows: The axis gets the default name from its axis parameter list[2]-18. The user must ensure the clear definition of the default axis name in the list.

< axis_number> The physical assignment of axes takes place through the logical axis number. Permissible are mathematical expressions.The logical axis number must be known in axes management.

With conflicts within the programmed axis exchange sequence: Redundant axes numbers - >ERROR, Abort of NC program With conflicts to already existing axes in NC channel: Axis number already exists in NC channel -> WARNING With active logic switch NBR the conflict is solved as follows: The axis request is ignored, this means it is not executed!

< axis_index> The axis index determines the location of the axis within the current axis group of the NC-channels. It defines the main and synchronous axes (see following table). Permissible are mathematic expressions, whose results are in the value range [0 ... Maximum axes number -1]. The axis index should not yet be allocated with an axis.

However, it must be noted that the index of a coupled axis is important as regards various functionalities. For example, all transformational axes must be arranged with no gaps based on the main axes in the case of kinematic transformation (RTCP). Thus, in such cases, it is necessary also to explicitly program the axis index for the coupled axes.

With conflicts within the programmed axis exchange sequence: Redundant axes indices -> ERROR, Abort of NC program With conflicts to already existing axes in NC channel: Axis index is already used in NC channel, Axes names different -> ERROR, Abort of NC program With active logic switch IDX the conflict is solved as follows: For the axis automatically the next free index in the axes configuration of the NC channel is determined.

<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 of the following table, during requests for axes, the inclusion of offsets can be controlled.

Example:

With the programming of DEFAULT the default configuration corresponding to the channel parameter list [1]-27 can be forced. Also the combination with logic switches and additional axes requests is possible.

# AX DEF DEFAULT  (non-modal)

or

# AX DEF DEFAULT [NAM, NBR, IDX] { [<axis_exchange_sequence> {,<options>} ] } (non-modal)

Example:

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

Programming example

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

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

Restoring of default axes configuration:

%Axis_exchange 
N10 #AX DEF DEFAULT 
: 

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