Moving the machine axes during an interruption

You can move the machine axes during an interruption in the same
way as in the Manual operation mode.
Danger of collision!
During a program interruption, the axes can be moved manually
(e.g., in order to retract out of a drilled hole. If, at the time of the
interruption, the Tilt the working plane function is active, then
the 3D ROT soft key becomes available. The 3D ROT function
can be used to deactivate the tilted working place or to limit
manual traverse exclusively to the active tool axis. A risk of
collision exists for incorrect 3D ROT settings!
It is better to use the TOOL AXIS function
Use a low feed rate
Modifying the preset during an interruption
If you modify the active preset during an interruption, resuming the
program run is only possible with GOTO or mid-program startup at
the interruption point.
Example:
Retracting the spindle after tool breakage
Interrupt machining
Enable the axis direction keys: Press the MANUAL TRAVERSE
soft key
Move the machine axes with the axis direction keys
On some machines you may have to press the NC start
key after the MANUAL TRAVERSE soft key to enable the
axis direction keys. Refer to your machine manual.
