Encoder Movement Distance 1000.000 mm
“Encoder Movement Distance” is mainly used for detecting the movement
distance of flying objects during the process of mark on the fly.
4.16. Helical Line
The helical line can be added to objects outside the frame and the following
parameters can be set: equal pitch, unequal pitch and helical line setting from
inward to outward or from outward to inward, as well as the minimum radius,
the minimum and maximum pitches of helical line, variation of pitch, number of
rings of outer and inner boundaries, etc., as shown in Fig. 4-51:
Helix can be added to the outer frame object, and parameters such as equal
pitch, unequal pitch, helix setting from inside to outside, from outside to inside,
and minimum radius, minimum helix pitch, maximum helix pitch, pitch variation,
outer boundary ring number, inner boundary ring number can be selected
