Axis status display

This function displays the axis status to the left of the axis name in the
coordinate display screen.

Axis status display

Explanation

- Outline of the axis status display

This function displays the axis status to the left of the axis name in the
display of the machine coordinates, absolute coordinates, relative
coordinates, and remaining travel amounts.
For example, when the mirror image function is enabled for the X1
axis, the absolute coordinates are displayed as follows.

By displaying the axis status as shown above, the function prevents
improper operations at the time of execution.

- Axis status indication

The axis status is indicated as follows. These indications are listed in
order of priority.

AXIS DETACH

- Settings

In the operation confirmation function setting screen, check or
uncheck the "AXIS STATUS DISPLAY" box to enable or disable this
function. For information about how to display the setting screen,
how to set the function, and other details, see the item “Operation
confirmation setting” that describes the setting of the operation
confirmation function.

6.5.2.4

Confirmation of the start from a middle block

This function displays a confirmation message when you attempt to
execute a memory operation with the cursor placed on a block in the
middle of the program.

Confirmation of the start from a middle block

Explanation

- Outline of the confirmation of the start from a middle block

This function displays the confirmation message "START FROM
MIDDLE OF PROG (START/RESET)" when you attempt to execute
a memory operation with the cursor placed on a block in the middle of
the program. It lets you confirm whether you really want to start
execution from that block or not before executing the program.
The function prevents you from inadvertently making a cycle start
from a block in the middle of the program.

- Settings

In the operation confirmation function setting screen, check or
uncheck the "START FROM MIDDLE OF PROGRAM" box to
enable or disable this function. For information about how to display
the setting screen, how to set the function, and other details, see the
item “Operation confirmation setting” that describes the setting of the
operation confirmation function.

6.5.2.5

Data range check

This function lets you set an effective data range and check whether
the data to be used for execution is within the set range.

Data range check

Explanation

- Outline of the data range check

This function lets you set an effective data range for each data item
listed later and check whether the data to be used for execution is
within the set range. If the data is out of the effective range, the
alarm PS0334 "OFFSET DATA OUT OF EFFECTIVE RANGE" is
displayed.
The function detects data setting mistakes and prevents the program
from running with invalid data.

- Data for which this function is effective

•

Tool

compensation

•

Workpiece origin offset

•

Y-axis tool offset

•

Workpiece

shift

NOTE

To use this function, you need to set each effective
data range correctly. For information about how to
set the data ranges, see the item “Effective value
range for each data”.

6.5.2.6

Maximum incremental value check

This function checks the maximum incremental value specified for
each axis by the NC command.

Maximum incremental value check

Explanation

- Outline of the maximum incremental value check

When the maximum incremental value is specified by the NC
command described later, make sure that the absolute value of the
travel distance by the incremental command does not exceed the
specified value. If the specified value is exceeded, the alarm PS0337
"EXCESS MAXIMUM INCREMENTAL VALUE" is displayed.
A maximum incremental value can be specified on a per-axis basis
and remains effective until 0 is set or the value is reset.
For example, when AI contour control is used, the function checks
whether the amount of movement between blocks is kept to the
specified value or less. Through this process, it detects erroneous
program settings and prevents the program from running with invalid
data.

- Format

The format of the NC command used to specify the maximum
incremental value is as follows.

G91.1 IP_ ;

IP_ ; Maximum incremental value

To cancel the maximum incremental value check, set 0.
