Counter wobble
The Counter wobble function is used in certain applications to obtain a constant yarn tension when the
Traverse control function is producing considerable variations in speed on the yarn guide motor
([Traverse freq. high] (trH) and [Traverse Freq. low] (trL), see [Traverse freq. high] (trH) page
227
).
Two motors must be used (one master and one slave).
The master controls the speed of the yarn guide, the slave controls the winding speed. The function assigns
the slave a speed profile, which is in antiphase to that of the master. This means that synchronization is
required, using one of the master’s logic outputs and one of the slave’s logic inputs.
