Default value: All 0
Bit 5 Path dimension from PLC, F73
This function provides a way of traversing NC axes in incremental or absolute
dimensions from the PLC. The data is transferred from the PLC to the NC via a
rapid "command channel". Tool offsets and zero offsets are not taken into account.
Application: positioning of auxiliary axes.
Bit 4 Indexing division from PLC
You must set this bit if indexing is to be used from the PLC.

and exit from
contour
Default value: All 0
Bit 6 Soft approach to and exit from contour
A contour tangential is approached or exited to avoid cutting edge marks. See the
Programming Guide.
Bit 5 Scale factor
You can simplify programming by entering a factor with which the coordinate values
of a part program can be weighted. See the Programming Guide.
Bit 2 High-resolution rotary axis
This option increases the position control resolution of rotary axes from the 0.005°
of the basic version to 0.000005°.
1) *
Bit 1 Increase of tool offset memory from 408 to 819 tools
The tool offset memory is expanded from 16 KB to 32 KB. This is enough for 819
tools if each tool has 10 parameters. The bit becomes active when you press the
softkey "Format tool data" and enter the initial clear mode.
1) *
Bit 0 Increase of tool offset memory from 204 to 409 tools
The tool offset memory is expanded from 8 KB to 16 KB. This is enough for 409
tools if each tool has 10 parameters. The bit becomes active when you press the
softkey "Format TO data" in initial clear mode.
_______
1) With SW 3 and higher, these bits can no longer be altered. The tool offset memory is set to 32 KB on
POWER ON RESET. Only these values are permissible if standard tool management is used.
* For SW 4 and higher see functional description "Flexible Memory Configuration".
