(6)V command during multi–piece machining
(7)M code for punch/laser switching
4.
Limitations
(1)The retrace function is optional.
(2)Machining cannot be restarted if the NC mode differs from that
selected when backward movement was started.
(3)In backward movement end mode, restart is not possible until the
backward movement signal is set to 0.
(4)Backward movement can be performed for up to about 50 blocks
(depending on the program).
(5)To start backward movement, first apply feed hold, then set the
backward movement signal to 1. If the backward movement signal
is set to 1 without applying feed hold, backward movement after
the execution of the current block may not be possible.

RVSG08 Look–ahead control restart signal
This signal is set to 1 when re–forward movement in look–ahead control
mode is completed and the tool is automatically stopped in the block in
which backward movement was started. The signal is set to 0 when
machining is subsequently restarted.
