22.6.2 Output of Program Restart M, S, T and B (2nd Auxiliary
Function) Codes
The following operations are possible after searching the program
execution restart block.
M, S, T and B (2nd auxiliary function) functions
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 (MOA)
parameter No. 7620.
2 Until arrival at the machining restart position
You can specify M, S, T and B codes (second auxiliary function)
in the program restart screen from the MDI panel in the
MEMORY or DNC modes.
