7 Conguring the "Winder Dancer" TA
For the dancer control, the web tension is generated exclusively via an upstream dancer
de
vice. The advantage of a dancer device is its compensaon behaviour in the event of
dynamic disturbances, e.g. those which occur during acceleraon and imbalances in the reel.
In this case, only the dancer posion changes while the tensile force remains constant. The
dancer control is used in cases where the tensile force accuracy and tensile force consistency
must remain within a very small tolerance zone. In the case of the dancer control, the limits
are not determined by the torque seng range, but by the mechanical design of the dancer,
the dynamics (mass, fricon etc.) and the speed seng range of the drive.
Dancer-controlled systems can be used to rewind and unwind the following example materials
at speeds of up to 1000 [m/min]:

Cable
