Retracting after a program interruption

Retracting in the Manual Operation mode
You can interrupt the thread cutting process by pressing the NC
Stop key. A soft key for retracting the tool from the thread is
displayed in the soft-key row below the screen. When you press
this soft key and the NC Start key, the tool retracts from the
hole and returns to the starting point of machining. The spindle
is stopped automatically and the TNC displays a message.
Retracting in the Program Run, Single Block or Full Sequence
mode
You can interrupt the thread cutting process by pressing the
NC Stop key. The TNC shows the soft key MANUAL TRAVERSE.
After pressing MANUAL TRAVERSE you can retract the tool
in the active spindle axis. To resume machining after the
interruption, press the RESTORE POSITION soft key and NC
Start. The TNC moves the tool back to the position it had
assumed before the NC Stop key was pressed.
Danger of collision!
A danger of collision exists if you move the tool during retraction
in a negative direction instead of e.g. in a positive direction.
When retracting the tool you can move it in the positive and
negative tool axis directions
Be aware of the direction in which you retract the tool from
the hole before retracting
