Because 2

/50 is a number with an infinite number of decimal digits, we can
choose the following:
Therefore, the parameters are:
With these settings, executing MOVE(50) moves the moving part 50 mm, or
one station.
Example 6
fig. 24
The mechanical system consists of a ball screw. It uses a servo motor with a
17-bit absolute encoder. The mechanical gear ratio of the gearbox is 1:3.
The screw pitch of the ball screw is 10mm per revolution. The total travel
distance of the ball screw is 540 mm. The mechanical measurement units
must be mm.
With the same procedure as in example 1, we have:
