6.2.6 MDT Scaling
Defining the Valid 16-bit Position Range
For general scaling information, see the Scaling Overview topic.
Because the RMC uses 16-bit positions, positions must all fit within a range of 65,536 position
units. Because position units are user definable, this range does not limit most applications. See
the section below on defining position units.
For MDT axes, the Offset parameter is used with the Scale parameter to define the position
range. If the Scale parameter is negative, then the position range extends from the Offset value
minus 65535 up to the Offset value. If the Scale parameter is non-negative, then the position
range extends from the Offset value up to the Offset value plus 65535. The following chart
summarizes this concept:
Scale Min. Position Max. Position
< 0 Offset - 65535 Offset
³ 0 Offset Offset + 65535
