The machine data
MD24030 $MC_FRAME_ACS_SET
can be used to set whether the SZS is with or without the prog. frame and the transformation
frame.
The value 0 is only made available for reasons of compatibility. The value 1 is set as a
default, and should be retained. All cycles should be reset so that they only use the cycle
frame.
Reconfiguring the SZS affects all SZS actual-value displays and the $AA_IEN[axis] system
variables. Traversing geometry axes in JOG mode in the SZS also depends on the
configuration.
2.4.5.3 Manual traverse in the SZS coordinate system
Previously, geometry axes have been traversed manually in JOG mode in the WCS. In
addition, there is also the option to carry out this manual operation in the SZS coordinate
system. The $AC_JOG_COORD variable enables the user to switch between manual
traversing in the WCS and SZS. The user can now select if he wants to traverse in the SZS
or the WCS.
