- Reverse movement →Forward return movement
Three methods are available for moving the tool in the forward direction
again along the retraced path.
1) When the tool is moving in the reverse direction, turn off the
REVERSE switch on the operator’s panel during block execution.
2) When the tool is moving in the reverse direction, turn off the
REVERSE switch on the operator’s panel after a single block stop.
3) When the tool is moving in the reverse direction, turn off the
REVERSE switch on the operator’s 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 the operator’s
panel does not immediately start forward return movement.
