Those blocks that are skipped do not affect the CNC. This means that the
data in the skipped blocks such as coordinates and M, S, and T codes does
not alter the CNC coordinates and modal values.
So, in the first block where execution is to be started or restarted by using
a sequence number search command, be sure to enter required M, S, and
T codes and coordinates. A block searched for by sequence number
search usually represents a point of shifting from one process to another.
When a block in the middle of a process must be searched for to restart
execution at the block, specify M, S, and T codes, G codes, coordinates,
and so forth as required from the MDI after closely checking the machine
tool and NC states at that point.
During search operation, the following checks are made:
Optional block skip
P/S alarm (No. 003 to 010)
During sequence number search operation, M98Pxxxx (subprogram call)
is not executed. So a P/S alarm (No.060) is raised if an attempt is made
to search for a sequence number in a subprogram called by the program
currently selected.
