4.6. Diameter Calculation with Winding Rolls: F07.062 = 5
With this mode encoder 1 receives line impulses from a measuring wheel or a feed roll of a
winder or unwinder application. Furthermore the counter needs one trigger impulse from the
rotation of the winding roll. From both signals the counter can calculate and display the actual
roll diameter. All counting occurs in the background and only updated diameter readings appear
in the display. Encoder 2 is not in use with this application.
The scaling parameters F07.066 and F07.067 are automatically set to the appropriate values
with this application. Parameter F07.068 allows setting a core diameter.
When set to zero, the display will show the full roll diameter.
When set to a core diameter, the display will show the remaining material diameter
(full diameter – core diameter).
Besides the total material length and the actual diameter the unit also records the extreme
diameter values (minimum and maximum) coming up during the process.
Presets K1 and K2 are related to the actual line counter of encoder 1 (total material length
under the measuring roll).
Presets K3 and K4 are related to the actual diameter value of the winding roll.
