SECTION 5 AUTOMATIC MODE OPERATION
6-2.
Sequence Restart
This function can be used only after the return search. (For the return search operation, refer to 6-1.
"Return Search" in this section.)
When the SEQ. RESTART switch on the machine
operation
panel is pressed, the program status up to the
specified block is returned automatically.
(1) Automatic Restoration of Miscellaneous Functions
(a)
Restoring the last
S code
If there is an S command, the S code of that command is executed unconditionally.
(b) A T code is
not restored automatically.
Since a T code (next tool command) is
not restored automatically, it is necessary to
set
the correct
tool number if the next tool number presently active
is
incorrect. If the
next
tool number
is "0", input
the tool number in the MDI operation before executing search.
(c) Only M codes related to spindle operation can be restored.
Since M codes are processed in groups, the last modal state of the individual M code groups is
restored.
-
M03, M04, M05, and M19 are regarded as M codes in the same group, and the last state of them
is restored.
-
M codes related to ATC operation (M06, M63, M64, and M65) and APC operation (M60, etc.) are
not restored automatically. The operator
must restore
the
correct status before restarting the
operation.
- One-shot
M codes (MOO, M01 , etc.) are not restored.
(d) The axes return to the point programmed in the return sequence
at
a manual
cutting feedrate.
(e) After
axes have reached the
return
point in the sequence return
operation,
the
operation stops
at that point independent of SINGLE BLOCK key setting. To resume the operation, the
CYCLE START switch must be pressed.
1) Key in N 100 after pressing function key [F2] (RESTART).
Then, press the WRITE key. This prepares for
the return of
the latest state up
to
the N100.
2) Press the SEQ. RESTART switch.
The miscellaneous commands (S, T, M) are output to the
PLC, then after the confirmation of the respective answer
signals,
the
axes
return to the point
commanded last
at
the
cutting feedrate.
3) After axes have reached the return point in the sequence
return operation, the operation stops at that point
independent of SINGLE BLOCK key
setting. To
resume
the
operation,
the CYCLE START switch must be pressed.
