Note:
The web width measurement provided in this register is in the number of pixels. In order to convert
that measurement to engineering units the conversion is as follows: 1 pixel = 0.0635 mm or 1 pixel = 0.0025
in.
Note:
The web width measurement output includes the compensation factor that is calculated during the
teaching process. For example, when two sensors are used to measure the two edge positions, the width
measurement output includes the compensation based on the distance between the two sensors.
Note:
The register will have a valid output only after the controller is taught for the nominal web width on
the SCU5.
Note:
If the filter is enabled the output provided would be the filtered output.
When the SCU5 controller is not set to provide width, then the registers provide the mean widths of the
webs seen by each sensor. Register 14 will provide the mean width of the webs seen by sensor 1 and register
15 will provide the mean width of the webs seen by sensor 2.
Note:
The mean width is computed by adding all the widths of the webs seen by each sensor and dividing it
by thread count. This measurement is an instantaneous raw measurement for each sensor. Enabling and
disabling the filter in the controller will have no effect on the measurement output.
