5.209 L_WndStopCtrl - stop controller
This FB serves to monitor the residual length to the reference diameter, on the basis of the current
diameter and the material thickness. Output signals for an accurately timed braking and a limit stop
are provided.
Inputs

Identifier/data type Information/possible settings
dwDiameter
DWORD
Current reel diameter in [μm]
• 1000 μm ≡ 1 mm; 1000000 μm ≡ 1 m
• Internal limitation to 10 m
dwThickness
DWORD
Current material thickness in [μm]
• 1000 μm ≡ 1 mm
