Programming Manual, 03/2006 Edition, 6FC5398-2BP10-1BA0
Geometry axis or channel/machine axis that retracts.
Axis designations of the valid single axes.
Position values of the single axes of the type:
Invalidate the position value
Position value is absolute
Position value is incremental (distance)
Retract position, WCS is valid for geometry axis, otherwise
MCS. If the identifiers for the geo axis and channel/machine
axis are identical, retraction is carried out in the workpiece
coordinate system.
Incremental programming is permissible.
Retraction position with type=1 for single axes
Retraction position with type=2 for single axes
The value is also accepted with type=0: Only this value is
marked as invalid and has to be reprogrammed for retraction.
The command POLF is modal.
If an axis is no a single axis, or if the type is missing or
type=0, the relevant alarms 26080 and 26081 are output.
The POLFMASK command enables the specified axes for retraction
– without a connection between axes.
The command POLFMASK() without any axis parameter deactivates
fastlift for all axes which were retracted without any
connection between axes.
The POLFMLIN command enables the specified axes for retraction
– with a linear connection between axes.
The command POLFMLIN() without any axis parameter deactivates
fastlift for all axes which were retracted with a linear
connection between axes.
Names of the axes that are to travel to positions defined with
POLF in case of LIFTFAST. All the axes specified must be in
the same coordinate system. Before fastlift to a fixed
position can be activated via POLFMASK or POLFMLIN, a position
must be programmed with POLF for the selected axes. No machine
data is provided for presetting the values of POLF.
During interpretation of POLFMASK or POLFMLIN, alarm 16016 is
issued if POLF has not been programmed.
