Chapter Four Operation
253
Part 2
Operation
（
c
）
The machine immediately stops due to storage type travel limit alarm.
（
d
）
The coordinate system changes after the last automatic operation.
Example:
（
i
）
Specify G92 command through MDI.
（
ii
）
Move the coordinate system
（
iii
）
Set the automatic coordinate system after reference point returning.
（ iv ） Press SHIFT key.
（
v
）
Coordinates are changed due to reset.
（ a ） After power on or releases of emergency stop and travel limit alarm, the machine performs
the reference point return prior to the restart (see the notes below)
（
b
）
The tool is manually moved to the programmed start point of machining. Set modal data and
coordinate system to the state that the same as the state of machine restart.
（
c
）
If necessary, set or change the offset.
（
d
）
Set the Program Restart key on the operation panel of the machine to ON.
（ e ） Display program by pressing PROGRAM key. Search required programs when it is not
available.
（ f ） Return the program to the start. Press cursor key ↓ in AUTO mode.
Use Q key Sequence Number , cursor key
∨
. to search the sequence number that
the block restarts.
When the same sequence number appears for many times during searching, the higher four
digits are specified as number of times of sequence number appearance and the lower four digits as
its sequence number
(a) When retrieving is finished, contents displayed by LCD screen is the same as the system
starts.
(b) Set Program Restart switch to OFF.
(c) Observe the screen, if M, S, T and B code are not displayed on the program restart page.
(d) When the tool moves to the machining restarting position, make sure the tool does not contact
workpiece. If necessary, manually move the tool to a position that does not contact the workpiece.
(e) Check if the distance indicated by the DISTANCE TO Go is adequate.
(f) Return to the Auto mode and press the Cycle Start key, the tool moves to the restarting position
by dry run in sequence of the 4
th
axis, X, Y and Z axis, and restart machining.
Note 1: In the following conditions, program is not restarted by pressing P , Sequence
Number and cursor key ↓ .
（
a
）
After power on, no automatic operation is performed.
（
b
）
Automatic operation is not performed after the release of emergency stop or storage
travel limit alarm.
（
c
）
The automatic operation is set after the coordinate system is established, changed or
moved (offset of external workpiece origin is changed)
The above （ a ），（ b ） or 94—97, alarm reset causes P/S 97 alarm.
P/S 94 alarm is issued by the establishment of a coordinate system
。
P/S 95 alarm is issued by the move of a coordinate system
。
P/S 96 alarm is issued by the alteration of a coordinate system
The block for the restartable machining is one of the many blocks. The block follows the
block when the coordinate system is last set or changed before the interruption of machining.
Note 2: In P or Q type, the tool moves to the machining restarting position by one axis each
time. The stop of a single block is possible after the motion of the axis is finished.
However, manual operation rather than MDI operation can be inserted. The returned
axes cannot move.
Note 3: When input signals, offsets and other conditions are different from the past in
searching, the tool cannot return to the machining starting position. Set the single
block switch to ON or switch to Auto mode for continuous search operation.
Note 4: When feed hold is active during search or reset operation is performed after search,
carry out program restarting operation from the beginning. After the search, change
parameter 007 “CLEAR” to the reset state in MDI mode at reset time.
Note 5: When program automatic restart switch is set to ON, cycle start can be ignored.
