Note that we have not used the pulley radius in the calculation. This is to
avoid the use of
π
, which cannot be expressed as a fractional number). In
toothed pulleys, the number of teeth and mm per tooth is commonly used.
The calculation of the multiturn limit setting is:
The smallest integer
m
for which this equation is valid is 8203. This results in
Pn205 = 8202.
In addition, to limit the motion units range to the moving range of the motion
part, the following axis parameters must be set:
REP_DIST = 4260
, and
REP_OPTION = 1
. With these settings, executing
MOVE(38)
moves the
moving part 38 mm in forward direction. The range of possible
MPOS
and
DPOS
values is 0 mm to 4160 mm.
