4 Applications
This chapter describes typical examples of winder applications. The function blocks used are described
in Chapter 5 “Function blocks”.
4.1
Example: Indirect tension control
The tension of a web is to be maintained at a fairly constant value. Tension-feedback which might be
used for direct control is not available.
•
The function block “Speed Setpoint” converts the Line Setpoint into a Reference Frequency such
that the winder drive wants to wind 5-10% faster than necessary at all times.
•
The function block “Tension Setpoint” limits the torque to a value which will be just sufficient for
developing the required tension at the current diameter.
•
The function block “Compensation Calculator” (Torque Compensation) calculates the torque addi-
tionally required for turning the winder and acceleration and adds it to the torque supplied by
function module “Tension Setpoint”.
