Note:
If scales with single/periodic reference marks are used, it is important to always to start from the end of travel and
to move the axis in the same direction during both setting and restoring reference
If scales with smart (distance coded) reference marks installed, it will only take about 1” of movement anywhere in either
direction along the axis to set or recover the absolute position.
