- Relation with other functions

The following table indicates the relation between other functions and
the movement by handle interruption.

Table 4.6(a) Relation between other functions and the movement by

handle interruption

Signals Relation

Machine lock

Machine lock is effective. When machine lock is on, no
movement is made due to handle interruption.

Interlock

Interlock is effective. When interlock is on, no movement
is made due to handle interruption.

Mirror image

Mirror image is not effective. Interrupt functions on the plus
direction by plus direction command, even if this signal
turns on.

- Position display

The following table shows the relation between various position
display data and the movement by handle interruption.

Table4.6(b) relation between various position display data and the

movement by handle interruption

Signals Relation

Absolute coordinate
value

Handle interruption does not change absolute
coordinates.

Relative coordinate value

Relative coordinates are changed by the travel
distance specified by handle interruption.

Machine coordinate
value

Machine coordinates are changed by the travel
distance specified by handle interruption.

- Travel distance display

Press the function key

, then press the chapter selection soft key

[HNDL]. The move amount by the handle interruption is displayed.
The following 4 kinds of data are displayed concurrently.

(a) INPUT

UNIT:

Handle interruption move amount in input unit system

Indicates the travel distance specified by handle interruption
according to the least input increment.

(b) OUTPUT UNIT :

Handle interruption move amount in output unit system

Indicates the travel distance specified by handle interruption
according to the least command increment.

Position in relative coordinate system

These values have no effect on the travel distance specified by
handle interruption.

(d) DISTANCE TO GO:

The remaining travel distance in the current block has no effect
on the travel distance specified by handle interruption.

The handle interruption move amount is cleared when the manual
reference position return ends every axis.

- Display for five-axis systems or better

Systems having five or more axes provide the same display as the
overall position display. See III-12.1.3.

Note

NOTE

1 In a manual operation mode such as the jog feed

mode, manual handle feed mode, or TEACH IN
HANDLE mode, handle interruption cannot be
performed.

2 During a machine lock or interlock, handle

interruption does not cause movement.

3 Manual handle interruption is disabled for the axis in

any of the following states.
- Follow-up state
- PMC axis control state

4 Manual handle interruption cannot be performed for

the axis specified in the G00 mode.

MIRROR IMAGE

During automatic operation, the mirror image function can be used for
movement along an axis. To use this function, set the mirror image
switch to ON on the machine operator's panel, or set the mirror image
setting to ON from the MDI panel.

Tool

Y-axis mirror image goes on.

Procedure for mirror image

Procedure

The following procedure is given as an example. For actual operation,
refer to the manual supplied by the machine tool builder.
1

Press the single block switch to stop automatic operation.

When the mirror image function is used from the beginning of
operation, this step is omitted.

Press the mirror image switch for the target axis on the machine
operator's panel.

Alternatively, turn on the mirror image setting by following the
steps below:
2-1 Set the MDI mode.
2-2 Press the function key

2-3 Press the [SETING] soft key for chapter selection to display

the setting screen.

2-4 Move the cursor to the mirror image setting position, then

set the target axis to 1.

3 Enter an automatic operation mode (memory mode or MDI

mode), then press the cycle start button to start automatic
operation.

Explanation

•

The mirror image function can also be turned on and off by
setting bit 0 (MIRx) of parameter No.0012 to 1 or 0.

•

For the mirror image switches, refer to the manual supplied by
the machine tool builder.

Limitation

The direction of movement during manual operation, the direction of
movement from an intermediate point to the reference position during
automatic reference position return (G28), the direction of approach
during single direction positioning (G60), and the shift direction in a
boring cycle (G76, G87) cannot be reversed.

PROGRAM RESTART

This function specifies Sequence No. of a block to be restarted when a
tool is broken down or when it is desired to restart machining
operation after a day off, and restarts the machining operation from
that block. It can also be used as a high-speed program check
function.
There are two restart methods: the P-type method and Q-type
method.

Procedure for program restart by specifying a sequence number

Procedure 1

[P TYPE]

Retract the tool and replace it with a new one. When necessary,
change the offset. (Go to step 2.)

[Q TYPE]

1 When power is turned ON or emergency stop is released,

perform all necessary operations at that time, including the
reference position return.

2 Move the machine manually to the program starting point

(machining start point), and keep the modal data and coordinate
system in the same conditions as at the machining start.

If necessary, modify the offset amount. (Go to step 2.)

Procedure 2

[COMMON TO P TYPE / Q TYPE]

Turn the program restart switch on the machine operator's panel
ON.

2 Press

key to display the desired program.

Find the program head. Press

key.

4 Enter the sequence number of the block to be restarted, then

press the [P TYPE] or [Q TYPE] soft key.

If the same sequence number appears more than once, the
location of the target block must be specified. Specify a
frequency and a sequence number.

The sequence number is searched for, and the program restart
screen appears on the LCD display.

Fig. 4.8 (a) Program restart screen

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 four axes.    If your system supports
five or more axes, pressing the [RSTR] soft key again displays
the data for the fifth and subsequent axes.
M :  Up to 35 most recently specified M codes.    The maximum

number of displayed M codes differs depending on the size
of the display.
With 15-inch or 10.4-inch LCD/MDI panel :

Up to 30 M codes

With 7.2/8.4-inch LCD/MDI panel : Up to 6 M codes

T  :  Two most recently specified T codes
S  :  Most recently specified S code
B  :  Most recently specified B 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.

Turn the program re-start switch OFF. At this time, the figure
at the left side of axis name DISTANCE TO GO blinks.

Check the screen for the M, S, T, and B codes to be executed.
If they are found, enter the MDI mode, then execute the M, S, T,
and B functions. After execution, restore the previous mode.
These codes are not displayed on the program restart screen.

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.

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 No. 7310 settings. Machining
is then restarted.
