ESP-SPAC-WND1 — Software Package Winder V2.2
Function description
This function block 'L_WndCalcThickness' calculates the mean material thickness in [µm] from the change of the reel diameter and the change of the angle of rotation of the reel shaft.
After the current input values (dwDiameter, dnPos_p) have been stored, a preset number of reel shaft revolutions (wCalcRef) are made before the material thickness is calculated from the diameter change.
The current diameter and the current angle of rotation are stored after each calculation so that the next calculation cycle can start.
With the setting wCalcRef= 1000 rev the initially saved reference values for diameter and angle of rotation are maintained. The first calculation is already made after 100 revolutions. After that, the calculation is repeated whenever the FB is called. After 10000 revolutions, the calculation stops. The state is indicated by a status display at the output (nState = 40).
Applications
The calculation of the material thickness is used in the winding technology sector.
