OPERATION

B-63534EN/02

4. AUTOMATIC OPERATION

Explanation

The previous explanation of how to execute and stop memory operation

also applies to MDI operation, except that in MDI operation, M30 does

not return control to the beginning of the program (M99 performs this

function).

D Erasing the program

Programs prepared in the MDI mode will be erased in the following cases:

S In MDI operation, if M02, M30 or ER(%) is executed.

(If bit 6 (MER) of parameter No. 3203 is set to 1, however, the

program is erased when execution of the last block of the program

is completed by single-block operation.)

S In MEMORY mode, if memory operation is performed.

S In EDIT mode, if any editing is performed.

S Background editing is performed.

S When the

O

and

DELETE

keys are pressed.

S Upon reset when bit 7 (MCL) of parameter No. 3203 is set to 1

D Restart

After the editing operation during the stop of MDI operation was done,

operation starts from the current cursor position.

D Editing a program during

A program can be edited during MDI operation. The editing of a program,

MDI operation

however, is disabled until the CNC is reset, when bit 5 (MIE) of parameter

No. 3203 is set accordingly.

Limitations

D Program registration

Programs created in MDI mode cannot be registered.

D Number of lines in a

A program can have as many lines as can fit on one page of the screen.

program

A program consisting of up to six lines can be created. When parameter

MDL (No. 3107 #7) is set to 0 to specify a mode that suppresses the

display of continuous-state information, a program of up to 10 lines can

be created.

If the created program exceeds the specified number of lines, % (ER) is

deleted (prevents insertion and modification).

D Subprogram nesting

Calls to subprograms (M98) can be specified in a program created in the

MDI mode. This means that a program registered in memory can be

called and executed during MDI operation. In addition to the main

program executed by automatic operation, up to two levels of subprogram

nesting are allowed (when the custom macro option is provided, up to four

levels are allowed).

By activating automatic operation during the DNC operation mode

(RMT), it is possible to perform machining (DNC operation) while a

DNC OPERATION

program is being read in via reader/puncher interface, or remote buffer.

If the floppy cassette directory display option is available, it is possible

to select files (programs) saved in an external input/output unit of a floppy

format (Handy File, Floppy Cassettes, or FA card) and specify (schedule)

the sequence and frequency of execution for automatic operation.

(see III-4.6)

To use the DNC operation function, it is necessary to set the parameters

related to the reader/punch interface, and remote buffer in advance.

position from which the tool can move to the machining restart

position without encountering any obstacles.

9

Press the cycle start button. The tool moves to the machining restart

position at the dry run feedrate sequentially along axes in the order

specified by parameter settings (No. 7310). Machining is then

restarted.

Explanations

D Block number

When the CNC is stopped, the number of executed blocks is displayed on

the program screen or program restart screen. The operator can specify

the number of the block from which the program is to be restarted, by

referencing the number displayed on the CRT. The displayed number

indicates the number of the block that was executed most recently. For

example, to restart the program from the block at which execution

stopped, specify the displayed number, plus one.

The number of blocks is counted from the start of machining, assuming

one NC line of a CNC program to be one block.

Macro statements are not counted as blocks.

D Storing / clearing the

The block number is held in memory while no power is supplied. The

block number

number can be cleared by cycle start in the reset state.

D Block number when a

The program screen usually displays the number of the block currently

program is halted or

being executed. When the execution of a block is completed, the CNC

stopped

is reset, or the program is executed in single-block stop mode, the

program screen displays the number of the program that was executed

most recently.

When a CNC program is halted or stopped by feed hold, reset, or

single-block stop, the following block numbers are displayed:

Feed hold : Block being executed

Reset : Block executed most recently

Single-block stop : Block executed most recently

For example, when the CNC is reset during the execution of block 10, the

displayed block number changes from 10 to 9.

D MDI intervention

When MDI intervention is performed while the program is stopped by

single-block stop, the CNC commands used for intervention are not

counted as a block.

D Block number exceeding

When the block number displayed on the program screen exceeds eight

eight digits

digits, the block number is reset to 0 and counting continues.

Limitations

D P-type restart

Under any of the following conditions, P-type restart cannot be

performed:

⋅

When automatic operation has not been performed since the power

was turned on

⋅

When automatic operation has not been performed since an

emergency stop was released

⋅

When automatic operation has not been performed since the

coordinate system was changed or shifted (change in an external

offset from the workpiece reference point)

D Restart block

The block to be restarted need not be the block which was interrupted;

operation can restart with any block. When P-type restart is performed,

the restart block must use the same coordinate system as when operation

was interrupted.

807

OPERATION

4. AUTOMATIC OPERATION

B-63534EN/02

D Single block

When single block operation is ON during movement to the restart

position, operation stops every time the tool completes movement along

an axis. When operation is stopped in the single block mode, MDI

intervention cannot be performed.

D Manual intervention

During movement to the restart position, manual intervention can be used

to perform a return operation for an axis if it has not yet been performed

for the axis. A return operation cannot be done further on axes for which

a return has already been completed.

D Reset

Never reset during the time from the start of a search at restart until

machining is restarted. Otherwise, restart must be performed again from

the first step.

D Manual absolute

Regardless of whether machining has started or not, manual operation

must be performed when the manual absolute mode is on.

D Reference position return

If no absolute-position detector (absolute pulse coder) is provided, be

sure to perform reference position return after turning on the power and

before performing restart.

WARNING

As a rule, the tool cannot be returned to a correct position under the following conditions.

Special care must be taken in the following cases since none of them cause an alarm:

S Manual operation is performed when the manual absolute mode is OFF.

S Manual operation is performed when the machine is locked.

S When the mirror image is used.

S When manual operation is performed in the course of axis movement for returning operation.

S When the program restart is commanded for a block between the block for skip cutting and

subsequent absolute command block.

D Handle interruption axis selection signals

For the handle interruption axis selection signals, refer to the manual

supplied by the machine tool builder.

During automatic operation, handle interruption is enabled for an axis

if the handle interruption axis selection signal for that axis is on.

Handle interruption is performed by turning the handle of the manual

pulse generator.

WARNING

The travel distance by handle interruption is determined

according to the amount by which the manual pulse

generator is turned and the handle feed magnification (x1,

x10, xM, xN).

Since this movement is not accelerated or decelerated, it is

very dangerous to use a large magnification value for

handle interruption.

The move amount per scale at x1 magnification is 0.001 mm

(metric output) or 0.0001 inch (inch output).

NOTE

Handle interruption is disabled when the machine is locked

during automatic operation.
