Warning
WARNING
If the feed is stopped during threading, without
stopping the spindle, the depth of cut increases
dangerously. Therefore, the feed hold function is
disabled during threading. If an attempt to apply
feed hold is made during threading, an operation like
a single block stop is made after the first non-
threading block following the end of the threading
mode is executed. The feed hold lamp (SPL lamp),
however, lights when the feed hold button (machine
operator’s panel) is pressed. When a stop is made,
the feed hold lamp goes off (the CNC enters the
single-block stop state).
Caution
CAUTION
1 During threading, the feedrate override function is
disabled, and the override value is held to 100%.
2 If the feed hold button is pressed again in the first
non-threading block after the threading mode (or if
the button is kept pressed), a stop is immediately
made at the beginning of the non-threading block.
3 If threading is performed in the single block state, a
stop is made after a non-threading block is
executed.
4 If two threading blocks are successively executed,
the second block does not begin with the detection
of a one-rotation signal. Instead it starts the
specified movement immediately.
5 During a dry run, the feedrate is set so that the
longitudinal speed matches the dry run speed.
