again along the retraced path.
1) When the tool is moving in the reverse direction, turn off the
REVERSE switch on the operators panel during block execution.
2) When the tool is moving in the reverse direction, turn off the
REVERSE switch on the operators panel after a single block stop.
3) When the tool is moving in the reverse direction, turn off
theREVERSE switch on the operators panel after a feed hold stop.
In the case of 1) above, the tool starts forward return movement after
completion of the block currently being executed (after execution up to
the position of a single block stop). Turning off the REVERSE switch on
