FANUC Series 30i-MODEL A
Start lock, Interlock signal
for each axis and direction
All axes Interlock signal *IT<G008#0>
[Classification] Input signal
[Function] This signal is used to inhibit the machine from moving, and is effective
regardless of the selected mode.
[Operation] When the *IT signal is “0”, the axis movement is decelerated and
stopped. In automatic operation, blocks containing M, S, T or B 2nd
auxiliary mode commands are executed consecutively until a block
containing an axis move command is encountered; the system then stops
and is placed into the automatic operation mode (cycle start lamp signal
STL is “1”, feed hold lamp signal SPL is “0”). When the *IT signal turns
to “1”, operation resumes (Figs. 2.5(c), (d)).
