Enter these values in the index card

"SYNCHRONIZATION" (the selected units
should always be whole numbers):
Syncfactor Master [49] = 2048
Syncfactor Slave [50] = 55
4.
Enter the gearing factor of the slave in UU
units:
Gearing factor = 5/1
Encoder resolution (incremental encoder) =
500
One revolution of the roller is 360 degrees. We
are going to work with a resolution of
1/10 degrees. This means that we are dividing
one revolution of the roller into 3600 work units:
Scaling factor = 3600
Enter these whole number values in the index
card

"ENCODER":
User factor numerator [23] = 25
User factor denominator [26] = 9
5.
Determine a whole number factor for the
intervals in the index card
→
"CURVE DATA"
so that the fixpoints are on the interpolation
points.
A complete cycle length of the master is
400 mm; this corresponds to 4000 MU.
The
→
"NUMBER OF INTERVALS" = 40
results in a reasonable interval time of 25 ms.

Define

"FIX POINTS" for the conveyor belt
(master) and the roller (slave) and the point
type „1“ for curve points. Click on the

"RECALC" button in order to depict the curve.
The function
→
"SNAP ON GRID" should be
activated.
7.
Master and slave must run synchronously with
the same velocity between the position 1500
and 2500. This requires a straight line which is
determined by two tangent points.
Enter „2“ for tangent point in the column
→
"TYPE" for the two positions in the index card
→
"FIX POINTS".
Alternatively, you can move the cursor to the
fixpoint 2500, click on the right mouse button
and select
→
"CHANGE TYPE" in the subse-
quent pop-up menu. Since two tangent points
are always required, the previous one (left) will
also be changed at the same time.
8.
The curve will not be shown because the cal-
culation of a spline always requires three
points. In this case, you will therefore need an
additional fixpoint before and after the tangent
(straight section).
