Reference values for line speed
The reference values for the line speed are set in Parameters
Line Speed Reference Value Hz
[mm/s] and
An absolute value function is applied internally to the line speed and winder speed be-
fore the calculation. For this reason, the sense of rotation of the winder drive and the
production direction do not have to be considered when setting up the Diameter Calcu-
lator.

Example of parameterization of 883 and 884
If the line speed is 1000 mm/s, the speed sensor at a clamping roll with a diameter of 100 mm will
supply the following frequency:
1000 mm/s
———————
100 mm · π
Since the speed sensor is connected to the winder frequency inverter, it uses the number of pole pairs
of the winder drive to calculate the electrical frequency of the speed sensor evaluation. In the case of
a drive with no. of pole pairs PPZ=2 twice the frequency would be output:
3.1831 s
The following parameter values result:
