If the bit [Single Block Operation Mode] is already ON before execution of par-
allel branching, each branch will be executed one block at a time. At the end
(JWAIT command) of parallel execution, branches follow execution of the
branch with the most blocks.
When the bit [Single Block Operation Mode] is turned ON during execution of
parallel branching, all the branches will be stopped at the ends of the blocks
currently being executed. When each block currently being executed in all the
branches is stopped, the bit [In Block Stop] will be turned ON.
The block with NSTOP command in the motion program will ignore the Single
Block Operation Mode. The Single Block Operation Mode will be ignored even
when the bit [Single Block Operating Mode] is turned ON during execution of
the block with NSTOP command, and execution will stop before the block
without NSTOP command.
NO.NSTOP
• Machine Lock function prohibits the output of movement commands to the
axes so that operation sequences other than axis operations can be
debugged.
• Though the output of movement commands to the axes is prohibited, cal-
culations for the movement commands are executed and command posi-
tion will be updated.
• Machine Lock can be used not only for debugging of the motion pro-
grams, but also for debugging of the ladder program in the CPU Unit.
Stops after execution of 1 bloc
Even in parallel execution, the
program stops after execution
of 1 block in each branch.
With NSTOP NO NSTOP
