In reverse movement and forward return movement, the skip signal is
ignored. In reverse movement and forward return movement, the beam
moves along the path actually followed in forward movement.

The M, T functions, and secondary auxiliary functions (B functions) are
output directly in reverse movement and forward return movement.
When an M, 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, 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 is modified in reverse movement or
forward return movement, the beam 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 nozzle has been moved by manual intervention, return the
nozzle to the original position before moving the nozzle in the reverse
direction after a feed hold stop or single block stop.In reverse movement,
the nozzle cannot move along the path made during manual intervention.
All movements made by manual intervention 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 beam
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 nozzle 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 beam moves along the
actual path incorporating the mirror image function.
CAUTION
During reverse movement, the nozzle may touch a
workpiece. To prevent this condition from occurring, raise
the nozzle, or take some other precautions, before starting
reverse movement.
