E70 Series Instruction Manual
2.3 Restart Search
I - 49
(1) Set the tool offset amounts and parameters before proceeding the program restart search. If they are not set
beforehand, the axes will not return to the proper machining start position.
(2) Attempting the automatic start up during the restart search causes "T01 Cycle start prohibit 0111" and it will
not start up automatically.
(3) The axes will not return to the proper machining start position if a program using the user macro external signal
input, machine coordinate readout or external mirror image command executes the restart search.
(4) If an attempt was made to shift the coordinate systems by manual or MDI interrupt the last time the machining
program was being executed, the axes will not return to the position where the coordinate system was shifted
whether it restarts with type 1 or type 2.
(5) When using the type 1, a top search for the head of the program is not available.
Restart search of the type 1 searches from the previous operation start block and locates the designated block
as it memorizes the operation start block previously operated.
(6) When "#8914 Auto Top search" is set to "0" for the type 2, an error message "Top search not completed" will
be displayed if the search is attempted directly with the type 2 without executing the top search.
Conduct the top search first.
(7) The macro statement blocks cannot be searched .
It is possible to execute the restart search if the control parameter "#8101 MACRO SINGLE" is set to ON.
However, note that the tool path may change because of the radius compensation, the corner R/C, and
geometric read ahead blocks.
(8) When executing the restart for the type 1 with a tape, the axes will not return to the proper machinig start
position if the opearation starts from midway of the tape.
(9) WHILE/GOTO statement cannot be used for a tape operation. Thus, if a restart search is executed with the
tape operation which includes WHILE/GOTO statement, a program error (P295) will occur.
(10) A search error will occur if an intended ONB is not found even M99 block is detected in the main program.
(11) A error will occur if the M99 block in the main program is searched.
(12) When "#1122 pglk_c (Program display lock C)" is set to "2", the restart search cannot be executed as
"Program display lock C" is applied.
(13) If both N and B are omitted, it will be assumed as the head of the program and the number of repetitions is
considered as "1" even the P number is designated.
(14) When either N or B is omitted, the omitted one is assumed as "0".
(15) When you execute the restart search to a block in synchronous tapping cycle modal, issue the S code for a
tapping spindle from MSTB history menu. If it is not issued, the tapping spindle will execute the syncronous
tapping with current gear step without changing the gear.
(16) The possible designation range of the number of program repetition P is up to the total value of the number of
identical sub program repetition L which is described on the program.
(17) When "#8129 sub pro No. selection" is set "1" or "2", it will be restart search by sub program with O No. So,
when program No. is designated, specifying "O" at the head of program No. is required.
