1.3.4 Data Ranges and Unit of Increment System
z Speed parameter
Machine tool types decide the units of linear axes speed, i.e. mm/min for metric machine system is;
0.1inch/min for inch machine system.
The range of linear axis speed parameter is codetermined by machine tool type and increment system.
For example: data parameter NO.027: upper limit of cutting feedrate.

deg/min
As rotary axes are not involved in metric-inch interconversion, the rotation speed unit is always
deg/min.
The switch between different increment systems may cause the excess of permitted running speed set
by data parameter. Therefore, at the first power-on after switching, the system automatically modifies
relevant speed parameters and gives an alarm.
z Increment parameter
The unit and range of linear axis speed parameter are codetermined by machine tool type and
increment system.
For example: parameter NO.045: X axis software limit.

As rotary axes are not involved in metric-inch interconversion, the rotary axis increment parameter unit
is determined by increment system types. The ranges of rotary axis increment parameters are the same as
that of metric machine tool.

Coordinate data
（

The unit of linear axis coordinate data is determined by metric/inch input system, namely, mm for
metric system, inch for inch system.
The ranges of linear axis coordinate data are codetermined by metric/inch input system and increment
system. It is the same as command data input ranges. Shown as follows:
