Question:
Which settings are necessary in the template for a rewinder or unwinder?
Answer:
Both templates (DancerControl and TensionControl) have the following configuration:
- Rewinder = positive line speed
- Unwinder = negative line speed
For an
unwinder the global variable
g_bUnwindOperation must be set to TRUE in addition. The following settings result:
a) Template
DancerControl:
- In the StopControl function the reference diameter is used for unwinding (C3143).
b) Template
TensionControl:
- In the FrictionCompensation function the compensation torque (friction) is inverted.
- In the StopControl function the reference diameter is used for unwinding (C3143).
- In theDiameterCalculation function the calculated diameter can only decrease with active web break monitoring (g_bUnidirekt = TRUE).
Note:
Use the global variable
g_bCCWOperation for the setting winding from the top or bottom.
