The M, S, and T functions, and secondary auxiliary functions (B
functions) are output directly in reverse movement and forward return
movement.
When an M, S, or T function, or secondary auxiliary function (B function)
is specified in a block containing a move command, the function and the
move command are output at the same time in forward movement, reverse
movement, and forward return movement. This means that the position
where an M, S, or T function, or secondary auxiliary function (B function)
is output differs in forward movement, reverse movement, and forward
return movement.
Even if a cutter compensation value or tool length compensation value is
modified in reverse movement or forward return movement, the tool
moves according to the compensation value used when the block was
executed in the forward movement.
All custom macro operations are ignored in reverse movement and
forward return movement.
The values of macro variables present at the end of forward movement
remain unchanged.
When the tool has been moved by manual intervention, return the tool to
the original position before moving the tool in the reverse direction after
a feed hold stop or single block stop.In reverse movement, the tool cannot
move along the path made during manual intervention. All movements
made by manual intervention are ignored in reverse movement and
forward return movement.
The tool cannot move along the path retraction or repositioning
performed using the tool withdrawal and return function. All retraction
and repositioning operations are ignored in reverse movement and
forward return movement.
When a block with the mirror image function specified by a signal or
setting is memorized in forward movement, the mirror image function is
eliminated; the block is memorized as originally programmed.
Accordingly, in reverse movement and forward return movement, the tool
moves along the programmed path.In reverse movement or forward
return movement, the mirror image function can be specified by a signal
or setting.
When the tool performs reverse movement or forward return movement
for a block where the mirror image function is specified by the
programmable mirror image code (G51.1), the tool moves along the
actual path incorporating the mirror image function.
