7. COORDINATE VALUE AND
A linear axis refers to an axis moving linearly, and for it values are
specified in mm or inches.
A rotation axis refers to a rotating axis, and for it values are specified in
For rotation axes, note the following:
D Inch–metric switching is not performed.
D The machine coordinate system is always normalized to the range
from 0deg to 360deg.
The rotation axis roll–over function rounds the absolute coordinate value
and relative coordinate value of a rotation axis to a coordinate value
within one rotation. This prevents coordinate values to overflow.
In an incremental command, the specified value is regarded as the amount
In an absolute command, the specified value is rounded to within one
rotation. The resulting coordinate value is used as the end point. A
parameter is used to specify whether to determine the move direction by
the sign of the specified value or by the move distance (the shortest move
distance to the end point is selected).
