MCO 305 Design Guide
5. Determine a whole number factor for the intervals in the index card → Curve Data so that the Fix points
are on the interpolation points. Set this using the "Set" button.
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.
6. Define → Fix points for the conveyor belt
(master) and the roller (slave). 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 that is
determined by two tangent points.
Double-click in the column → Type for the
fixpoint at position 2500.
Alternatively, you can move the cursor to the
fixpoint 2500, click on the right mouse button
and select → Change Type in the subsequent
context menu. Since two tangent points are
always required, the previous one (at 1500)
will also be changed at the same time.
8. Activate the diagram of the →
see the corresponding velocity curve:
9. Enter the → Cycles/min Master = 60 in the index card → Curve Info. This is the (maximum) number of
cardboard boxes that are processed per minute.
10. Verify whether the acceleration of the slave is within the limit. For this purpose, you must activate the
illustration of the →
11. In order to load the curve into your control system, you must first save the file as a .zbc file by clicking
the "Save As" button. You will see the name of the curve and the number of array elements in the title
bar. You will need the latter for the DIM instruction during programming.
12. Load the .zbc file with the modified parameters and the – automatically generated – curve arrays into
the FC 300 by means of Parameters → Restore from file.
