13.7.2 NC-controlled reactions to retraction
Function
NC-controlled reactions require certain initial conditions listed below as restrictions. If these
prerequisites for retraction are satisfied, fast retraction will be activated.
The retraction position POLF must be programmed in the parts program. The activate
signals must be set for the retraction movement and remain set.
Programming
POLF[geo |mach]=,= value Target position of retracting axis
POLFA(axis, type, value)
Retraction position of single axes
The following abbreviated forms are
permitted:
POLFA(axis, type)
POLFA(axis, 0/1/2)type)
Abbreviated form for single axis
retraction
high-speed deactivation / activation
POLFA(axis, 0, $AA_POLFA[axis])
POLFA(axis, 0)
causes a preprocessing stop
does not cause a preprocessing stop
POLFMASK(axisname1, axisname2, ...)
Axis selection for the retraction
unconnected axes
POLFMLIN(axisname1, axisname2, ...)
Axis selection for the retraction
linearly connected axes
Notice
If the type is changed when using the abbreviated forms of POLFA, the user must ensure that
either the retraction position or the retraction path are assigned a meaningful value. In
particular, the retraction position and the retraction path have to be set again after Power On.
