If a machining cycle being executed is interrupted by a reset or emergency
stop at (X), machining can be restarted at machining cycle start point (H)
after starting the machining retreat program. In this case, use the
following sequence:
1. Return the tool to machining cycle start point (H) with the retreat
program.
2. Press the
RESET
key.
3. Select the restart of machining at the machining cycle start point with
the machining restart point select switch.
4. Set the program restart switch to on.
5. Set the machining restart switch to on.
Thus, search operation is performed by virtually executing the programs
from the start of program number 1000 to machining cycle start sequence
number 8020 stored in macro variables. Upon completion of search
operation, the machining restart completion lamp is turned on.
Then, by pressing the cycle start button, machining is restarted from block
(I).
If a machining cycle being executed is interrupted by a reset or emergency
stop at (Y), machining can be restarted at the machining cycle start point
after starting the machining retreat program. In this case, the restart
sequence is the same as “restart of machining from a machining cycle
restart point (A),” except that the restart sequence number is 8030, and
machining is restarted at block (N) because the hole bottom reach flag is
set in a macro variable.
The following requirements must be satisfied to restart machining:
1. MEM mode is set.
2. The reset state is set.
3. Background editing is not performed.
4. Data required for machining cycles is stored in macro variables.
5. The notes for program restart operation must be observed.
