PROGRAM SEARCH

When memory holds multiple programs, a program can be searched
for. There are four methods as follows.

Procedure for program search

Method 1

1 Select EDIT or MEMORY mode.

2 Press function key

to display the program screen.

3 Enter a program number or program name. When entering a

program number, press address key

then type the program

number.

4 Press soft key [PROGRM SEARCH]. Alternatively, press the cursor

key

5 Upon completion of search operation, the program number searched

for is displayed in the upper-right corner of the screen

If the program is not found , alarm PS0071 occurs.

Method 2

1 Select EDIT or MEMORY mode.

2 Press function key

to display the program screen.

3 Press soft key [PROGRM SEARCH].

4 Then, press soft key [PREV PROGRM] or [NEXT PROGRM].

Pressing [PREV PROGRM] searches for the previous program on the
folder, and pressing [NEXT PROGRM] searches for the next program.

Method

This method searches for the program number (0001 to 0031)
corresponding to a signal on the machine tool side to start automatic
operation. Refer to the relevant manual prepared by the machine tool
builder for detailed information on operation.

1 Select MEMORY mode.

2 Set the reset state.

•

The reset state is the state where the LED for indicating that
automatic operation is in progress is off. (Refer to the relevant
manual of the machine tool builder.)

3 Set the program number selection signal on the machine tool side to a

number from 01 to 31.

4 Press the cycle start button.

•

When the signal on the machine tool side represents 00, program
number search operation is not performed.

•

If the program corresponding to a signal on the machine tool side
is not registered, alarm DS0059 is raised.

Method 4

When bit 4 (PGS) of parameter No. 11308 is 1, search for an O number
program by specifying digits only.

1 Select EDIT or MEMORY mode.

2 Press function key

to display the program screen.

3 Enter the digits of a program number. Address key

need not be

pressed before the digits.

4 Press soft key [PROGRM SEARCH]. Alternatively, press the cursor

key

Example

•

When bit 4 (PGS) of parameter No. 11308 is 1

Specify

"1000"

→

Search for program O1000.

Specify

"ABC"

→

Search for program ABC.

•

When bit 4 (PGS) of parameter No. 11308 is 0

Specify

"1000"

→

Search for program 1000.

Specify

"ABC"

→

Search for program ABC.

When bit 4 (PGS) of parameter No. 11308 is 1, it is not possible to
search for a program with any name consisting of digits only.

SEQUENCE NUMBER SEARCH

Sequence number search operation is usually used to search for a
sequence number in the middle of a program so that execution can be
started or restarted at the block of the sequence number.

Example)

Sequence number 02346 in a program (O0002) is searched for.

PROGRAM
O0001 ;
N01234 X100.0 Z100.0 ;

S12 ;

O0002 ;

N02345 X20.0 Z20.0 ;

N02346 X10.0 Z10.0 ;

O0003 ;

Selected program

Target sequence

number is found.

This section is searched
starting at the beginning.
(Search operation is
performed only within a

program.)

Procedure for sequence number search

Procedure

Select MEMORY mode.

Press function key

If the program contains a sequence number to be searched for,
perform the operations 4 to 7 below.

If the program does not contain a sequence number to be
searched for, select the program number of the program that
contains the sequence number to be searched for.

Press address key

Key in a sequence number to be searched for.

Press soft key [N SRH].

7 Upon completion of search operation, the sequence number

searched for is displayed in the upper-right corner of the screen.

If the specified sequence number is not found in the program
currently selected, alarm PS0060 occurs.

Explanation
- Operation during Search

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

- Checking during search

During search operation, the following checks are made:

•

Optional block skip

Limitation
- Searching in sub-program

During sequence number search operation, M98Pxxxx (subprogram
call) is not executed. So an alarm PS0060 is raised if an attempt is
made to search for a sequence number in a subprogram called by the
program currently selected.

O1234

:
:

M98 P5678 ;

Main program

Subprogram

O5678

N88888

M99 ;

If an attempt is made to search for N8888 in the example above, an alarm occurs.
