6.8 Process Control
This section introduces three commonly used process control functions, the wobble function, fixed
length and counting.
6.8.1 The Wobble Function
The wobble function is applicable to industries such as textile and chemical fiber and winding
and unwinding applications. It indicates output frequency wobbles up and down with frequency
reference as center.
