Syntax
POLF(<axis>)=<position>
POLFA(<axis>,<type>,<position>)
POLFMASK(<axis_1>,<axis_2>,...)
POLFMLIN(<axis_1>,<axis_2>,...)
The following abbreviated forms are permitted for
POLFA(<axis>,<type>) ; Abbreviated form for single axis retraction
POLFA(axis,0/1/2) ; Quick deactivation or activation
POLFA(axis,0,$AA_POLFA[axis]) ; Causes a preprocessing stop
POLFA(axis,0) ; Does not cause a preprocessing stop
Meaning

: Address for specifying the target position of the retraction axis
is modal.
POLF
:
<axis>
<position>
: Predefined subprogram call for the specification of the retraction position of
single axes
:
<axis>
:
<type>
<position>
Name of the geometry or channel/machine axis that
retracts
: Retraction position
Type: REAL
WCS is valid for geometry axes, otherwise MCS.
With the same identifiers for geometry and
channel/machine axes, retraction is in the WCS.
Channel axis identifier
Position specification mode
Type: INT
Value: :
0
:
1
:
2
Note:
If an axis is not a single axis or if the type is missing or
type=0, then a corresponding alarm is output.
: Retraction position (see above)
Note:
The position value is also accepted with type=0. Only this
value is marked as invalid and has to be reprogrammed
for retraction.
