Warning message

Content

START REJECTED

This program cannot be drawn.

NO PROGRAM SELECTED

No drawing target program is selected.

UNAVAILABLE COMMAND IS IN DRAWING

An NC statement/macro statement that can not execute drawing
is instructed.

ILLEGAL SETTING OF GRAPHIC PARAMETERS

Graphic parameters are not set correctly.

ILLEGAL SETTING OF TOOL FIGURE DATA

Tool figure data are not set correctly, or tool figure data are not
exist.

13.2.5

Note

NOTE

1 The coordinates used in drawing are absolute coordinates.

Therefore, even if the coordinate system is changed while it is drawing, it draws in
the coordinate system when having begun to draw.

2 The drawing target axes are the basic three axes.

The basic three axes are the X-axis, Y-axis, and Z-axis on the basic coordinate
system set with parameter No.1022.

3 In a drawing program having a sequence of contiguous small blocks, drawing

requires longer processing time, possibly causing machining time to become longer
than actual machining time.

4 When drawing is executed, data is treated as described below.

(1) Parameters

The same parameters as for automatic operation are used. However,
parameters cannot be rewritten with a command such as the G10 command.
If an attempt is made to rewrite a parameter with programmable parameter
input (G10L52), the command is ignored.
However, by setting bit 7 (GST) of parameter No.11329, drawing can be
temporarily stopped with the warning "UNAVAILABLE COMMAND IS IN
DRAWING".

(2) Tool compensation value/workpiece origin offset/extended workpiece origin

offset/macro variable/fixture offset data, etc.
For each of drawing execution and automatic operation, separate data is used.
At the start of drawing, data for drawing is produced by copying data for
automatic operation.    In subsequent operations, the data for drawing and the
data for automatic operation are treated independently of each other.    So,
even if data is rewritten with a command such as G10, drawing execution and
automatic operation do not affect each other.    Note, however, that data
rewritten in drawing execution is not reflected in the data for automatic
operation but is deleted.

(3) Tool life management data, tool number offset data, three-dimensional error

correction data
These data items are not used for drawing execution. So, if an attempt is
made to rewrite data with G10, the command is ignored.
However, by setting bit 7 (GST) of parameter No.11329, drawing can be
temporarily stopped with the warning "UNAVAILABLE COMMAND IS IN
DRAWING".

Restrictions

- Simultaneous drawing with multiple paths

This function does not support simultaneous tool path drawing by
program execution with multiple paths.
For example, the tool paths of programs executed simultaneously with
multiple paths on a 2-path or 3-path lathe or a combined machine tool
cannot be drawn. This function supports only drawing executed
singly with a single path.

- Simultaneous multipath display

The screens of this function do not support simultaneous multipath
display based on the setting of parameter No. 13131 and No. 13132.

- Functions that operate differently in drawing execution and automatic operation

The operations of the following functions in drawing execution differ
from the operations in automatic operation:

1. Operations that differ, depending on the custom macro

1) Interface

signal

#1000 to #1035 are assumed to be 0 at all times.

2) Message

output

A message to be output with #3006 is not displayed but is
ignored.

3) clock

#3001 and #3002 are ignored. So, note that drawing is not
continued, for example, if the following is specified:
#3001=0 ;
WHILE [#3001 LE 100] DO1 ;
END1 ;

4) Mirror

image

#3007 is assumed to be 0 at all times.

5) Program-restarted

state

#3008 is assumed to be 0 at all times.

6) External output command

BPRNT, DPRNT, POPEN, and PCLOS are ignored.

Functions that perform partly different operations
1) When G28 (automatic reference position return) is specified,

up to the intermediate point is drawn.

2) When G29 (automatic return from the reference position) is

specified, drawing is performed from the intermediate point.

3) When G27 (reference position return check) is specified, no

reference position return check is made.

4) No stored stroke limit check is made.
5) When G31 (skip function), or G31.1, G31.2, or G31.3

(multistage skip function) is specified, drawing is performed
up to the specified position, regardless of the skip signal.

6) When G60 (single direction positioning) is specified,

drawing is performed directly up to the specified position at
all times even if the positioning direction is opposite.

- Dynamic switching of diameter/radius specification in the background operation

It is possible to perform drawing by switching the amount-of-travel
setting on each axis that is to be specified in the drawing program to a
diameter or radius value, using programmable switching of
diameter/radius specification (G10.9 command) of the function of
dynamic switching of diameter/radius specification.

When the G10.9 command of the function of dynamic switching of
diameter/radius specification is enabled (bit 5 (PGD) of parameter No.
3400 = 1), drawing is performed by internally switching the
diameter/radius specification for the move command for each axis in
the background operation, as follows:

•

If the specified address value is 0 (radius specification)

→

Drawing is performed with the radius specification.

•

If the specified address value is 1 (diameter specification)

→

Drawing is performed with the diameter specification.

NOTE

1 For the G10.9 command in the background

operation, the diameter/radius specification
switching status signal of the function of dynamic
switching of diameter/radius specification is not
output.

2 The diameter/radius specification switching signal

of the function of dynamic switching of
diameter/radius specification is ineffective to the
background operation.

3 The switching due to the G10.9 command in the

background operation is canceled if the
background operation is stopped.

4 Using this command requires the function of

dynamic switching of diameter/radius specification.

Data items and commands that can be switched

For the following data item and command, switching of
diameter/radius specification is performed according to the
switched specification:
-

Move command from a program

Current position display

•

Data items that cannot be switched

For the following data items, switching of diameter/radius
specification is not performed because they follow the setting of
bit 3 (DIAx) of parameter No. 1006.
- Parameter
- Offset
-

Workpiece coordinate system

In custom macros, coordinates that can be read with the system
variables indicating position information, listed below.
#5001 to #5020 and #100001 to #100050: End point position in
the immediately preceding block (workpiece coordinate system)
#5021 to #5040 and #100051 to #100100: Specified current
position (machine coordinate system)
#5041 to #5060 and #100101 and #100150: Specified current
position (workpiece coordinate system)
#5061 to #5080 and #100151 to #100200: Skip position
(workpiece coordinate system)

NOTE

For offsets, the settings of bit 1 (ORC) and bit 2
(ODI) of parameter No. 5004 take precedence.

Screen center coordinates and values of blank (position) drawing
parameters are handled with radius specification regardless of the
setting of parameter bit DIAx.

- Operation of the P-CODE workpiece number search function in the background

operation

When drawing is started with the setting of bit 3 (WNS) of parameter
No. 11349, the execution macro specified in system variable #8610 is
executed before the drawing program.

•

Calling conditions and operations
a) Bit 6 (PWSR) of compilation parameter No. 9002 is set to

b) The program number of an execution macro is set in system

variable #8610 before the start of drawing.

If the conditions above are met, pressing soft key [START] or
[1BLOCK] to execute drawing causes the following operations
to be performed:

GRAPHIC

FUNCTION

OPERATION

B-63944EN/03

- 1954 -

(1) The execution macro specified with system variable #8610

is called.
If bit 4 (P98) of compilation parameter No. 9163 is 0, the
execution macro is called with an operation equivalent to a
simple call (G65), and if P98 is 1, it is called with an
operation equivalent to a subprogram call (M98).

(2) When the execution macro terminates, the drawing program

is executed.

NOTE

1 This function calls an execution macro if the

conditions described in a) and b) are met,
regardless of the program selected. Thus, if using
this function to perform drawing with an execution
macro, modify the program of the execution macro
so that macro statements, auxiliary functions, and
other commands in the execution macro that are
not necessary for drawing are not executed, by
referring to the system variable below.

#3010

-1 Drawing

execution

2 System variable #8610, referenced during the

execution of drawing, is the same as that used
during automatic operation. If, therefore, the value
of the variable is changed to execute drawing, it is
necessary to return the variable to the original
value before automatic operation is performed.
Also, automatic operation is performed with the
variable value at the time drawing is started and,
therefore, caution is required so that the value set
is not changed during automatic operation.

•

Nesting and local variables

Nesting is accumulated in an execution macro. An execution
macro is called with an operation equivalent to a simple call
(G65) or a subprogram call (M98) and, therefore, other execution
macros can be called from the called execution macro with all
calling methods.

In the case of an operation equivalent to a simple call (G65), the
level of local variables is changed to that of the drawing program.
That is, the drawing program do not inherit the local variables
used in the execution macro.

In the case of an operation equivalent to a subprogram call (M98),

the local variables at the same level as the drawing program are
used. That is, the drawing program inherits the local variables
used in the execution macro.

- Drawing start position

In tool path drawing, if G92, G52, or G92.1 (machining center
system) or G50, G52, or G50.3 (lathe system) is specified at the start
of a drawing target program, the position specified with the G code is
the drawing start position. If none of these G codes is specified, the
end point of the first moving command is the drawing start position.
In animation drawing, the current position when the tool figure is
displayed is the drawing start position.
