7.15.1.2 Monitoring based on the dancer posion
In
addion to web monitoring, which operates on the basis of the direcon of the diameter
change, web breaks can also be considered the most likely cause of the dancer reaching the
lower limit posion during operaon in the case of dancer posion-controlled winders.
The method on which the web break monitoring is based is dened in the parameter Method
of web break monitoring. 40x5051:073
Method of web break monitoring 0x5051: 073 Bit Status Informaon

18 TRUE A web break is detected
when the Eecve actual
dancer posion falls below
the Threshold for lower
dancer posion when the
dancer control is acve.

also be based on detect-
ing changes in the diame-
ter. When the diameter
changes in a direcon dif-
ferent to the one expec-
ted, web break monitor-
ing is triggered.

The web break monitoring is acvated by seng bit 24 = TRUE in the parameter Con
trol sig-
nal. 40x5050:010 Bit 24
When a web break has been detected, bit 24 = TRUE is set in the parameter Status signal.
