POLF[]:
<Axis name>: Name of a geometry axis or machine axis
Note
LFON or LFOF can always be programmed, but the evaluation is performed exclusively during
thread cutting (G33).
Note
POLF with POLFMASK/POLFMLIN are not restricted to thread cutting applications.
Figure 5-1
Dynamic response of the retraction motion
The retraction motion is executed with maximum axis dynamic response:
● MD32000 $MA_MAX_AX_VELO[<Axis>] (velocity)
● MD32300 $MA_MAX_AX_ACCEL[<Axis>] (acceleration)
● MD32431 $MA_MAX_AX_JERK[<Axis>] (jerk)

Define absolute retraction position for the geometry axis or machine axis in
the index
Effectiveness: modal
In the case of geometry axes, the assigned value is inter‐
=<Value>:
preted as a position in the workpiece coordinate system. In
the case of machine axes, it is interpreted as a position in the
machine coordinate system.
The values assigned can also be programmed as incremen‐
tal dimensions:
