Coordinate Data
Programming machine-referenced coordinates:
M91/M92
Scale reference point
On the scale, a reference mark indicates the position of the scale
reference point.
Machine datum
The machine datum is required for the following tasks:
Defining the limits of traverse (software limit switches)
Moving to machine-referenced positions (such as tool change
