DESTINATION shows the position at which machining is to restart.

DISTANCE TO GO shows the distance from the current tool position

to the position where machining is to restart. A number to the left of

each axis name indicates the order of axes (determined by parameter

setting) along which the tool moves to the restart position.

The coordinates and amount of travel for restarting the program can

be displayed for up to five axes. If your system supports six or more

axes, pressing the [RSTR] soft key again displays the data for the

sixth and subsequent axes. (The program restart screen displays only

the data for CNC-controlled axes.)

M: Fourteen most recently specified M codes

T: Two most recently specified T codes

S: Most recently specified S code

Codes are displayed in the order in which they are specified. All

codes are cleared by a program restart command or cycle start in the

reset state.

6

Turn the program re-start switch OFF. At this time, the figure at the

left side of axis name DISTANCE TO GO blinks.

7

Check the screen for the M, S, and T codes to be executed. If they are

found, enter the MDI mode, then execute the M, S and T functions.

After execution, restore the previous mode.

These codes are not displayed on the program restart screen.

8

Check that the distance indicated under DISTANCE TO GO is correct.

Also check whether there is the possibility that the tool might hit a

workpiece or other objects when it moves to the machining restart

position. If such a possibility exists, move the tool manually to a

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.

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 P-type restart

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

performed:

D When automatic operation has not been performed since the power

was turned on

D When automatic operation has not been performed since an emergency

stop was released

D 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.

B-63524EN/01

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

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

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 (

1,

10, M, N).

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

1 magnification is 0.001

Handle interruption is disabled when the machine is locked

during automatic operation.

During DNC operation, the program currently being executed is

displayed on the program check screen and program screen.

The number of displayed program blocks depends on the program being

executed.

Any comment enclosed between a control-out mark (() and control-in

mark ()) within a block is also displayed.

D Custom macro

In DNC operation, custom macros can be specified, but no repeat

instruction and branch instruction can be programmed. If a repeat

instruction or branch instruction is executed, P/S alarm No. 123 is issued.

When reserved words (such as IF, WHILE, COS, and NE) used with

custom macros in DNC operation are displayed during program display,

a blank is inserted between adjacent characters.

4.10.1

“DNC operation with Memory Card” is a function that it is possible to

perform machining with executing the program in the memory card,

Specification

which is assembled to the memory card interface, where is the left side

of the screen.

There are two methods to use this function as follows.

(a) By starting automatic operation

(cycle start) during the DNC

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

operation) while a program is being read from a memory card, as by

using the external input/output unit such as a floppy cassette and so on.

(Fig. 4.10.1 (a))

(b) It is possible to read sub-programs written in the memory card and

execute them by the command Subprogram call (M198). (Fig. 4.10.1

(b))
