If an encoder is available enable the Length Outputs and set the Preceding Length and Full Length.
The procedure for the PI stability settings is explained in Controller Tuning, below.
It is assumed that the commissioning engineer has sufficient knowledge of winder control systems.
Controller Tuning - Speed Control
It is essential that all motor drives are correctly set in accordance with the suppliers instructions BEFORE
the Controller is commissioned. The Controller will not compensate for incorrectly set drives.
The winder drive should be set so that any tension error due to speed changes is as small as possible.
In Speed mode, with the tension OFF, the unwind speed voltage as determined by the diameter
calculator and the line speed only will be output from the Control Out terminal TB4/5. This should
correspond closely to +10V at minimum diameter and maximum speed if the Output Level Limit is 100%.
Output Level Bias
This item should be set to 0% in Speed Control mode.
Output Level Limit
This item should be set to a value equivalent to the winder drive speed input voltage at maximum speed.
If the winder drive speed input at maximum speed is +10V this item should be set to 100%, if the winder
speed input at maximum speed is +5V set this to 50%.
PI Stability Settings
There are two methods of setting the PI stability; through the Product Parameter menu with the machine
at rest or through the Adjust PI stability menu with the machine running.
Access the Adjust PI stability menu from the Commissioning menu. Run the machine with the Controller
in Auto at a Tension Set Point of approximately 50%. Use the SCROLL keys to select the parameter to be
