Function blocks

For winder applications, the special function blocks described below are available.
5.1

Dancer control

The dancer control is a universal-use PID controller. The reference and actual values are defined via
percentage sources set in Parameters
The output is connected as an additional reference frequency directly to the speed controller input.
The dancer control can be used both for controlling a dancer position and for direct tension control,
e.g. via a pressure measuring device.
Control deviation is limited internally to a maximum of 300%.
