4.8 OUTPUT OF PROGRAM RESTART M, S, T AND B CODES
The following operations are possible after searching the program
execution restart block.
1 Before moving to the machining restart position
(1) The final M, S, T and B codes can be automatically output to
the PMC. If the final S code is specified to the same block
containing an G92, that S code is output as the maximum
spindle speed. Other S codes are output as the programmed
spindle speed. However, note that only the final programmed
S code is displayed in the program restart screen regardless
of whether it is specified in the same block as G92.
(2) All sampled M codes and the final S, T and B codes can be
automatically output to the PMC during searching of the
program execution restart block. However, note that only up
to 35 M codes can be sampled. If the number of M codes to
be sampled exceeds 35, the latest 35 M codes are output to
the PMC.
Whether (1) or (2) is to be performed is switched by bit 6 (BOA)
parameter No. 7620.
2 Until arrival at the machining restart position
You can specify M, S, T and B codes in the program restart screen
from the MDI panel in the MEMORY or TAPE modes.
Output of final M, S, T and B codes
If the Cycle Start button is pressed after the program execution restart
block is searched when bit 3 (MOP) of parameter No. 7620 is set to "1",
the final M, S, T and B codes are automatically output to the PMC
before the tool moves to the machining restart position.
If the Cycle Start button is pressed again after the final M, S, T and B
codes are output when the machine tool is in a single block halt state,
the tool moves to the machining restart position.
