ALF=… Programmable traverse direction (in motion block)
DISABLE(n) Deactivate interrupt routine number n
ENABLE(n) Reactivate interrupt routine number n
CLRINT(n) Clear interrupt assignments of interrupt routine number n
Retraction movement
The direction of the retraction movement is programmed by means of the G code LFTXT or
LFWP with the variable ALF.
• LFTXT
The plane of the retraction movement is determined by the path tangent and the tool
direction. This G code (default setting) is used to program the response on a fast lift.
• LFWP
The plane of the retraction movement is the active working plane selected with G codes
G17, G18 or G19. The direction of the retraction movement is not dependent on the path
tangent. This allows a fast lift to be programmed parallel to the axis.
• LFPOS
Retraction of the axis declared with POLFMASK to the absolute axis position
programmed with POLF. See also NC-controlled retraction in Function Manual M3
ALF has no affect on the lift direction for several axes and for several axes in a linear
system.
In the plane of the retraction movement, ALF is used, as before, to program the direction in
discrete steps of 45 degrees. With LFTXT, the retraction is defined in the tool direction for
ALF=1.
With LFWP the direction in the working plane is derived from the following assignment:
• G17:X/Y-levelALF=1retraction in X-direction
ALF=3retraction in Y-direction
• G18:Z/X-levelALF=1retraction in Z-direction
ALF=3retraction in X-direction
• G19:Y/Z-levelALF=1retraction in Y-direction
ALF=3retraction in Z-direction
