R3: Extended stop and retract
6.2 Control-managed ESR
Change coordinate system
If the coordinate system is to be changed, rapid lift must first be deactivated using POLFMASK
orPOLFMLIN, and only then can programming commence with POLF in the new coordinate
system.
Deactivate rapid lift
POLFMASK or POLFMLIN without specifying an axis deactivates rapid lift for all axes activated
in the enable call.
Interactions, POLFMASK/POLFMLIN
The last data entered for a specific axis in one of the two instructions applies. For example:
Program code
N200 POLFLIN(X,Y,Z)
...
N300 POLFMASK(Z)
N500 POLFMLIN(X,Z)
Part program start
The retraction positions (POLF) and axial enable signals (POLFMASK, POLFMLIN) are deleted
when the part program is started. This means that the user must reprogram the retraction
positions and the axial enable signals (POLFMASK, POLFMLIN) in every part program.

Possible trigger sources

A distinction must be made between the ESR trigger sources on a user-for-user basis by
evaluating system variables. This is the reason that all system variables are available, which
can be read in synchronized actions.

Description
; Linear retraction motion for X, Y and Z
; Independent retraction for Z
; (no longer any linear interpolation with X and Y)
; Linear retraction motion for X and Z
; The independent retraction of Z, activated with POLFMASK, is
; deleted. The retraction of Y, activated with POLFMLIN, is
; also deleted.
; Only X and Z carry out a retraction movement
