General

This chapter describes how to edit programs registered in the CNC.

Editing includes the insertion, modification, deletion, and replacement of

words. Editing also includes deletion of the entire program and automatic

insertion of sequence numbers. The extended part program editing

function can copy, move, and merge programs. This chapter also

describes program number search, sequence number search, word search,

and address search, which are performed before editing the program.

Explanation

D Concept of word and

A word is an address followed by a number. With a custom macro, the

editing unit

concept of word is ambiguous.

So the editing unit is considered here.

The editing unit is a unit subject to alteration or deletion in one operation.

In one scan operation, the cursor indicates the start of an editing unit.

An insertion is made after an editing unit.

Definition of editing unit

(i) Program portion from an address to immediately before the next

address

(ii)An address is an alphabet, IF, WHILE, GOTO, END, DO=,or ; (EOB).

According to this definition, a word is an editing unit.

The word “word,” when used in the description of editing, means an

editing unit according to the precise definition.

WARNING

The user cannot continue program execution after altering, inserting, or deleting data of the

program by suspending machining in progress by means of an operation such as a single block

stop or feed hold operation during program execution. If such a modification is made, the

program may not be executed exactly according to the contents of the program displayed on

the screen after machining is resumed. So, when the contents of memory are to be modified

by part program editing, be sure to enter the reset state or reset the system upon completion

of editing before executing the program.

9. EDITING PROGRAMS

OPERATION

B-63534EN/02

Explanations

Those blocks that are skipped do not affect the CNC. This means that the

D Operation during Search

data in the skipped blocks such as coordinates and M, S, and T codes does

not alter the CNC coordinates and modal values.

So, in the first block where execution is to be started or restarted by using

a sequence number search command, be sure to enter required M, S, and

T codes and coordinates. A block searched for by sequence number

search usually represents a point of shifting from one process to another.

When a block in the middle of a process must be searched for to restart

execution at the block, specify M, S, and T codes, G codes, coordinates,

and so forth as required from the MDI after closely checking the machine

tool and NC states at that point.

D Checking during search

During search operation, the following checks are made:

⋅ Optional block skip

⋅ P/S alarm (No. 003 to 010)

Limitations

D Searching in

During sequence number search operation, M98Pxxxx (subprogram call)

sub-program

is not executed. So a P/S alarm (No.060) is raised if an attempt is made

to search for a sequence number in a subprogram called by the program

currently selected.

OPERATION

9. EDITING PROGRAMS

Editing a program while executing another program is called background

9.8

editing. The method of editing is the same as for ordinary editing

BACKGROUND

(foreground editing).

EDITING

A program edited in the background should be registered in foreground

program memory by performing the following operation:

During background editing, all programs cannot be deleted at once.

Procedure for background editing

1

Enter EDIT or MEMORY mode.

Memory mode is allowed even while the program is being executed.

2

Press function key

PROG

3

Press soft key [(OPRT)], then press soft key [BG-EDT].

The background editing screen is displayed

(PROGRAM

(BG-EDIT) is displayed at the top left of the screen).

4

Edit a program on the background editing screen in the same way as

for ordinary program editing.

5

After editing is completed, press soft key [(OPRT)], then press soft

key [BG-EDT]. The edited program is registered in foreground

program memory.

Explanation

D Alarms during

Alarms that may occur during background editing do not affect

background editing

foreground operation. Conversely, alarms that may occur during

foreground operation do not affect background editing. In background

editing, if an attempt is made to edit a program selected for foreground

operation, a BP/S alarm (No. 140) is raised. On the other hand, if an

attempt is made to select a program subjected to background editing

during foreground operation (by means of subprogram calling or program

number search operation using an external signal), a P/S alarm (Nos. 059,

078) is raised in foreground operation. As with foreground program

editing, P/S alarms occur in background editing. However, to distinguish

these alarms from foreground alarms, BP/S is displayed in the data input

line on the background editing screen.

OPERATION

B-63534EN/02

The password function (bit 4 (NE9) of parameter No. 3202) can be locked

9.9

using parameter No.

3210

(PASSWD) and parameter No.

3211

PASSWORD

(KEYWD) to protect program Nos. 9000 to 9999. In the locked state,

FUNCTION

parameter NE9 cannot be set to 0. In this state, program Nos. 9000 to 9999

cannot be modified unless the correct keyword is set.

A locked state means that the value set in the parameter PASSWD differs

from the value set in the parameter KEYWD. The values set in these

parameters are not displayed. The locked state is released when the value

already set in the parameter PASSWD is also set in parameter KEYWD.

When 0 is displayed in parameter PASSWD, parameter PASSWD is not

set.

Procedure for locking and unlocking

Locking

1

Set the MDI mode.

2

Enable parameter writing. At this time, P/S alarm No. 100 is issued

on the CNC.

3

Set parameter No. 3210 (PASSWD). At this time, the locked state is

set.

4

Disable parameter writing.

5

Press the

RESET

key to release the alarm state.

Unlocking

1

Set the MDI mode.

2

Enable parameter writing. At this time, P/S alarm No. 100 is issued

on the CNC.

3

In parameter No. 3211 (KEYWD), set the same value as set in

parameter No. 3210 (PASSWD) for locking. At this time, the locked

state is released.

4

Set bit 4 (NE9) of parameter No. 3202 to 0.

5

Disable parameter writing.

6

Press the

RESET

key to release the alarm state.

7

Subprograms from program Nos. 9000 to 9999 can now be edited.

Explanations

D Setting parameter

The locked state is set when a value is set in the parameter PASSWD.

PASSWD

However, note that parameter PASSWD can be set only when the locked

state is not set (when PASSWD = 0, or PASSWD = KEYWD). If an

attempt is made to set parameter PASSWD in other cases, a warning is

given to indicate that writing is disabled. When the locked state is set

(when PASSWD = 0 and PASSWD = KEYWD), parameter NE9 is

automatically set to 1. If an attempt is made to set NE9 to 0, a warning

is given to indicate that writing is disabled.

D Changing parameter

Parameter PASSWD can be changed when the locked state is released

PASSWD

(when PASSWD = 0, or PASSWD = KEYWD). After step 3 in the

procedure for unlocking, a new value can be set in the parameter

PASSWD. From that time on, this new value must be set in parameter

KEYWD to release the locked state.
