6 Press the CURSOR<±> key.
7 Upon completion of search operation, the sequence number searched
for is displayed in the DPL screen.
Those blocks that are skipped do not affect the controller. This means that
the data in the skipped blocks such as coordinates and M, S and T codes
does not alter the controller 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 code 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 status
of the controller 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 an 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.
