POLF:
POLFA:
POLFMASK:
POLFMLIN:
Note
Before rapid retraction to a fixed position can be enabled via POLFMASK or POLFMLIN, a
position must have been programmed with POLF for the selected axes.
Note
If axes are enabled one after the other with POLFMASK, POLFMLIN or POLFMLIN, POLFMASK,
then the last definition always applies for the particular axis.

Programming Manual, 12/2019, 6FC5398-2EP40-0BA0
Address for specifying the target position of the retraction axis
POLF is modal.
Name of the geometry or channel/machine axis that retracts
<axis>:
Retraction position
<position>:
Type:
WCS is valid for geometry axes, otherwise MCS.
With the same identifiers for geometry and channel/machine
axes, retraction is in the WCS.
Predefined subprogram call for the specification of the retraction position of single
axes
Channel axis identifier
<axis>:
Position specification mode
<type>:
Type:
Value:
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)
<position>:
Note:
The position value is also accepted with type=0. Only this value
is marked as invalid and has to be reprogrammed for retraction.
Predefined subprogram call for selection of the axes that are to be retracted after
tripping of rapid lift independently of one another.
Names of the axes that are to be traversed to their positions
<axis_1>,...:
defined with POLF during rapid lift.
All the axes specified must be in the same coordinate system.
POLFMASK() without specification of an axis deactivates the rapid lift for all axes that
have been retracted independently of one another.
Predefined subprogram call for selection of the axes that are to be retracted after
tripping of rapid lift in linear relation.
See above.
<axis_1>,...:
POLFMLIN() without specification of an axis deactivates the rapid lift for all axes that
have been retracted in linear relation.
3.21 Extended stop and retract (ESR)
REAL
INT
Mark position value as invalid
0:
Position value is absolute
1:
Position value is incremental (distance)
2:
