When a tilted working plane command is not included in a 
block at the cursor position on a program editing screen 
 

The command type selection screen is displayed. A 
block created on the guidance screens is inserted after 
the block at the cursor position on the program editing 
screen. 

2  When a tilted working plane command is included in a 

block at the cursor position on a program editing screen 
 

The tilted working plane data setting screen is 
displayed, which shows the data for the tilted working 
plane command in the block at the cursor position on 
the program editing screen. When a block of a tool 
axis direction control command exists immediately 
after the tilted working plane command, the command 
data for the block is also shown. The tilted working 
plane command in the block at the cursor position on 
the program editing screen is replaced with a block 
created on the guidance screen. 

 

NOTE 

 

If the CNC is in the reset state or emergency stop 
state when horizontal soft key [GUIDANCE TWP] 
is pressed on the foreground editing screen or MDI 
editing screen, the warning "PROGRAM READ

NOTE 

1  For existing block modification, if the guidance 

screen is displayed when the cursor is placed in 
the middle of multiple blocks for a command, the 
parameters for the block(s) before the cursor are 
not reflected in the setting and selection items, but 
only the parameters for the block(s) after the 
cursor are reflected. If no data is to be reflected in 
a setting or selection item, the initial value is set in 
the item. 

2  For existing block modification, only the commands 

with parameter-specified axis names are reflected 
in the setting items on the screen. (The values 
specified in data for commands with incorrect axis 
names are not reflected in the setting items.)

Insertion of a block 

If the guidance screen is displayed when the block at the cursor 
position on the program editing screen does not include a tilted 
working plane command, horizontal soft key [INSERT] is displayed 
on the tilted working plane data setting screen. An operation for 
inserting a tilted working plane command block is described below. 
For warnings that may be issued at the time of block insertion, see 
"Limitation". 
 
1 

Press horizontal soft key [INSERT]. 
The confirmation message "ARE YOU SURE YOU WANT TO 
EXECUTE?" is displayed, and horizontal soft keys [YES] and 
[NO] are displayed. 

2 

Press horizontal soft key [YES]. 
A block is created from the command type and command data 
and then is inserted after the block at the cursor position in the 
program to be edited. After block insertion, the guidance screen 
is closed and the program editing screen is displayed. 
Pressing horizontal soft key [NO] takes you back to the tilted

Replacement of a block 

If the guidance screen is displayed when the block at the cursor 
position on the program editing screen includes a tilted working plane 
command, horizontal soft key [ALTER] is displayed on the tilted 
working plane data setting screen. An operation for replacing a tilted 
working plane command block is described below. 
For warnings that may be issued at the time of block replacement, see 
"Limitation".

  Press horizontal soft key [ALTER]. 

The confirmation message "ARE YOU SURE YOU WANT TO 
EXECUTE?" is displayed, and horizontal soft keys [YES] and 
[NO] are displayed. 

2

 

  Press horizontal soft key [YES]. 

A block is created from the command type and command data 
and then replaces the tilted working plane command in the block 
at the cursor position on the program editing screen. After block 
replacement, the guidance screen is closed and the program 
editing screen is displayed. 
Pressing horizontal soft key [NO] takes you back to the tilted 
working plane data setting screen. 

 

NOTE 

1  If a block to be replaced includes a command other 

than a tilted working plane command, the 
command is deleted during block replacement. 
However, only the sequence number at the 
beginning is preserved. 

2  If the guidance screen is displayed when the cursor 

is placed in the middle of multiple blocks for a 
command, the block(s) before the cursor are not 
replaced. These blocks remain unchanged after 
replacement. 

3  If horizontal soft key [GUIDANCE TWP] is pressed 

when the cursor is placed on a block of a tool axis 
direction control command, the command type 
selection screen is displayed in new insertion 
mode. A block created on the guidance screens is 
inserted after the block of the tool axis direction 
control command.

Warning Description 

“PROGRAM WRITE 
FAILED” 

•

  The guidance screen was displayed from the foreground 

editing screen or MDI editing screen, and a block insertion 
or replacement operation was performed when the CNC 
was in the reset state or emergency stop state.

 

”PROGRAM 
CANNOT BE 
WRITTEN” 

•

  A block insertion or replacement operation was performed 

after a program to be edited was updated due to program 
downloading by an external application while the guidance 
screen was displayed. 

•

  A block insertion or replacement operation was performed 

after the start of the main program was located by a reset 
while the guidance screen was displayed.

 

“WRITE PROTECT” 

•

  A block insertion or replacement operation was performed 

when the editing or display was prohibited for a program to 
be edited. 

•

  A block insertion or replacement operation was performed 

when the memory protection signal (KEY signal) for 
program registration or editing was off. 

•

  A block insertion or replacement operation was performed 

when the operation level of the 8-level data protection 
function was lower than the protection level of a part 
program editing operation.

 

 

Display of the command type selection screen 

When horizontal soft key [COMMAND TYPE] is pressed, the 
command type selection screen is displayed. When the command type 
is changed on the command type selection screen, the values set on the 
tilted working plane data setting screen are cleared. 
When a tilted working plane command is included in the block at the 
cursor position on the program editing screen, you can display the 
guidance screen, change the command type on the command type 
selection screen, and then perform block replacement. In this case, the 
block at the cursor position on the program editing screen is replaced 
with a block created from the command type and command data that 
have been set.

Absolute: 
 

It is assumed that values of specified data are in a workpiece 
coordinate system, regardless of whether tilted working 
plane command mode is set. 

Incremental: 
 

It is assumed that values of specified data are in a feature 
coordinate system if tilted working plane command mode is 
already set.

Origin of Feature Coordinate 

 

Specify the origin (X, Y, and Z of point P) of a feature 
coordinate system as coordinates in a workpiece coordinate 
system (for the absolute type) or the current feature coordinate
