Single Block
When the SINGLE BLOCK switch on the machine operation panel is switched ON, the single block
function is turned on and the program
stops
after executing the current program block.
There are two types
of single blocks.
(1) Execute Single Block
This stops by the block accompanying
axis movement execution, miscellaneous function
operation
or coordinate system setting. This does not stop by control statements such as CALL,
GOTO, etc.,
or a
macro call
command,
return
command, and NOEX statement.
(2)
Read Single Block
This stops at all blocks including
the
control statement.
(a) Execute single block is generally used, but for checking programmed operation, read single
block is used.
(b) Read single block is switched on by setting 1 at bit 0 of NC optional
parameter
(bit) No. 2.
(c) Execute single block is determined by switch status after one-block execution.
The read single block
is determined by switch
status
when one block is read.
(d) If
the single block is switched on during automatic
operation and single block OFF
state,
the
block under execution is completed and the machine
stops operation. If there is any buffered
block
at
this
stage,
one block is executed every time the CYCLE START switch is pressed. If
the buffer empties, a new block is read and executed.
(e) Read single block is used to stop the execution of
a program
by each control statement, IF,
GOTO
and VSET in
the
schedule program.
(f) During the program execution
called in MDI mode, setting of the SINGLE BLOCK key is
effective.
(g) For the details of the stopping manner during fixed cycle operation, refer to "FIXED CYCLES"
in the Programming Manual.
(h) During the area machining mode, the axis stops at the completion of each motion when the
single block is on.

Optional Block Skip
When the BLOCK SKIP switch on the machine
operation panel is switched ON, the block skip function is
turned on and the blocks preceded by the slash code (/) are skipped.
For details, consult "OPTIONAL BLOCK SKIP" in the Programming Manual.
