WebPro Winder Tension Controller
Controller Tuning - Clutch Winder
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.
Output Level Bias
Thread up and run the machine slowly with a reel at minimum diameter (core). With the Controller in Auto
adjust the tension set point slowly using the +/- keys until the measured tension digital display and bar
graph shows the minimum desired tension as set in the Machine Parameter menu. Record the output %
value. Stop the machine and enter this % value as the Output Level Bias in the Machine Parameter
menu.
Output Level Limit
Thread up and run the machine slowly with a reel of maximum diameter. Select high tension and with the
Controller in Auto increase the tension set point slowly using the +/- keys until the measured tension
digital display and bar graph shows 100%, maximum. Record the output % value. Stop the machine and
enter this % value as the Output Level Limit in the Machine Parameter menu.
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
changed and adjust the parameter using the numeric keys or the +/- keys. Press the CONFIRM key to
implement and save the change. An asterisk alongside the Product Number indicates that a parameter
has been changed and that the CONFIRM key must be pressed to implement and save the change.
When the best performance is achieved stop the machine, remember to press CONFIRM and then press
SET UP to return to the Commissioning menu.
To simplify the tuning there are five factory set PI values. One of these values should be suitable for most
applications. If it is found necessary to apply different PI values, select Custom and starting from PI
values that gave stable but sluggish operation, reduce the P band % value and reduce the I time value
until the desired performance is achieved. Remember to press the CONFIRM key before exiting the
Product Parameter or the Adjust PI stability menus in order to implement and save any changes.
The five preset PI values are:
very slow slow medium fast very fast
Proportional band 2000% 1200% 800% 500% 200%
Integral time 20 sec 12 sec 8 sec 5 sec 2 sec
Soft Start and Soft Stop Time
The Controller is activated immediately the Machine Start or Select Auto contact is closed or the Auto key
is pressed. In Clutch Winder mode only, the Controller remains active for the Soft Stop Time after the
Machine Start or Select Off contact is opened. This will maintain control as the machine slows to rest. The
Controller is de-activated immediately the Tension Off key is pressed.
