2.1.4.4.2. Winder/Unwinder

Use this template to enter required inputs to calculate the load profile for Winder
or Unwinder applications.

Figure 91 - Winder/Unwinder Template

For a Winder or Unwinder application, two index moves are created:

Maximum diameter, minimum rotation speed

(= maximum torque for center driven)

Minimum diameter, maximum rotation speed

(= minimum torque for center driven)

The maximum torque condition is the worst case for winding temperature so the
move time for this index is made large enough to dominate the temperature
calculations.

The maximum speed case is included to check that the specified speed can be
reached. If the application requires a different acceleration for the full roll
compared to the core, this can be done in
