Activation of the inch measuring system
The inch measuring system is used to read and write geometric data in units of length.
Technological data in units of length, e.g. feedrates, tool offsets or settable zero offsets, as
well as machine data and system variables, are read and written using the parameterized
basic system (MD10240 $MN_SCALING_SYSTEM_IS_METRIC).
Activation of the metric measuring system
The metric measuring system is used to read and write geometric data in units of length.
Technological data in units of length, e.g. feedrates, tool offsets or settable zero offsets, as
well as machine data and system variables, are read and written using the parameterized
basic system (MD10240 $MN_SCALING_SYSTEM_IS_METRIC).
Activation of the inch measuring system
All geometrical and technological data in units of length (see above) are read and written
using the inch measuring system.
Activation of the metric measuring system
All geometrical and technological data in units of length (see above) are read and written
using the metric measuring system.
