Enable the machine axis direction buttons.
Move the axes with the machine axis direction buttons.
On some machines you may have to press the machine START button after the MANUAL OPERATION soft key
to enable the axis direction buttons. See your machine tool manual.
Resuming program run after an interruption
• If a program run is interrupted during a fixed cycle, the program must be resumed from the beginning of the
cycle. This means that some machining operations will be repeated.
• If the program run is interrupted during a program section repeat or during a subprogram, you must use the
function RESTORE POS AT N to resume program run from the same point.
When a program run is interrupted the TNC stores:
• The data of the last called tool
• Active coordinate transformations
• The coordinates of the last defined circle center
The stored data are used for returning the tool to the contour after
manual machine axis positioning during an interruption (RESTORE
POSITION).
Resuming program run with the START button.
You can resume program run by pressing the machine START button if
the program was interrupted in one of the following ways:
• Pressing the machine STOP button
• A programmed interruption
