As rotary axis is not involve in metric-inch interconversion, the unit of rotary axis coordinate data is
deg. The ranges of rotary axis coordinate data is the same as linear axis coordinate data ranges in metric
system.

z Tool compensation data
The unit of tool compensation data is determined by metric/inch input system, namely, mm for metric
input, inch for inch input.
The range of tool compensation data is limited as 9999999, determined by inch input system and
increment system. It is smaller than command data. Shown as follows:

Screw-pitch error compensation data
The unit and range of linear axis screw-pitch error compensation data is codetermined by machine tool
type and increment system.

Rotary axes are not involved in metric-inch conversion. The unit of rotary axes screw-pitch error
compensation is determined by increment system. The range is the same as that of the metric machine
tool.
